题
多种颜色 NSString
或者 NSMutableStrings
不可能。所以我听说过 NSAttributedString
这是与 iPad SDK 3.2 (或大约3.2),并且在iPhone上可用 iPhone SDK 4.0 Beta.
我想拥有一个具有三种颜色的字符串。
我不使用3个单独的NSSTRINGS的原因是因为三个的长度 NSAttributedString
子字符串经常发生变化,因此我希望不使用任何计算来重新定位3单独 NSString
对象。
如果有可能使用 NSAttributedString
我如何进行以下操作 - (如果不可能使用NSATTRIB的字符串,您将如何做):
编辑:记住, @"first"
, @"second"
和 @"third"
随时将被其他字符串替换。因此,使用硬编码的nsrange值无法正常工作。
解决方案
当构建归因的字符串时,我更喜欢使用可变的子类,只是为了使情况保持更干净。
话虽如此,这是您创建一个三色属性字符串的方式:
NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@"firstsecondthird"];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,5)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(5,6)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(11,5)];
在浏览器中输入。 警告实施者
显然,您不会在这样的范围内进行硬码。也许您可以做类似的事情:
NSDictionary * wordToColorMapping = ....; //an NSDictionary of NSString => UIColor pairs
NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@""];
for (NSString * word in wordToColorMapping) {
UIColor * color = [wordToColorMapping objectForKey:word];
NSDictionary * attributes = [NSDictionary dictionaryWithObject:color forKey:NSForegroundColorAttributeName];
NSAttributedString * subString = [[NSAttributedString alloc] initWithString:word attributes:attributes];
[string appendAttributedString:subString];
[subString release];
}
//display string
其他提示
问题已经得到回答...但是我想展示如何添加阴影并使用NSATTRIBETDERSTRING更改字体,以便当人们搜索此主题时,他们不必继续寻找。
#define FONT_SIZE 20
#define FONT_HELVETICA @"Helvetica-Light"
#define BLACK_SHADOW [UIColor colorWithRed:40.0f/255.0f green:40.0f/255.0f blue:40.0f/255.0f alpha:0.4f]
NSString*myNSString = @"This is my string.\nIt goes to a second line.";
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.alignment = NSTextAlignmentCenter;
paragraphStyle.lineSpacing = FONT_SIZE/2;
UIFont * labelFont = [UIFont fontWithName:FONT_HELVETICA size:FONT_SIZE];
UIColor * labelColor = [UIColor colorWithWhite:1 alpha:1];
NSShadow *shadow = [[NSShadow alloc] init];
[shadow setShadowColor : BLACK_SHADOW];
[shadow setShadowOffset : CGSizeMake (1.0, 1.0)];
[shadow setShadowBlurRadius : 1];
NSAttributedString *labelText = [[NSAttributedString alloc] initWithString : myNSString
attributes : @{
NSParagraphStyleAttributeName : paragraphStyle,
NSKernAttributeName : @2.0,
NSFontAttributeName : labelFont,
NSForegroundColorAttributeName : labelColor,
NSShadowAttributeName : shadow }];
这是一个迅速的版本...
警告!这适用于4s。
对于5s,您必须将所有浮点值更改为双值(因为编译器尚未正常工作)
Swift Enum选择字体:
enum FontValue: Int {
case FVBold = 1 , FVCondensedBlack, FVMedium, FVHelveticaNeue, FVLight, FVCondensedBold, FVLightItalic, FVUltraLightItalic, FVUltraLight, FVBoldItalic, FVItalic
}
用于枚举访问的Swift数组(需要枚举无法使用' - '):
func helveticaFont (index:Int) -> (String) {
let fontArray = [
"HelveticaNeue-Bold",
"HelveticaNeue-CondensedBlack",
"HelveticaNeue-Medium",
"HelveticaNeue",
"HelveticaNeue-Light",
"HelveticaNeue-CondensedBold",
"HelveticaNeue-LightItalic",
"HelveticaNeue-UltraLightItalic",
"HelveticaNeue-UltraLight",
"HelveticaNeue-BoldItalic",
"HelveticaNeue-Italic",
]
return fontArray[index]
}
Swift属于文本功能:
func myAttributedText (myString:String, mySize: Float, myFont:FontValue) -> (NSMutableAttributedString) {
let shadow = NSShadow()
shadow.shadowColor = UIColor.textShadowColor()
shadow.shadowOffset = CGSizeMake (1.0, 1.0)
shadow.shadowBlurRadius = 1
let paragraphStyle = NSMutableParagraphStyle.alloc()
paragraphStyle.lineHeightMultiple = 1
paragraphStyle.lineBreakMode = NSLineBreakMode.ByWordWrapping
paragraphStyle.alignment = NSTextAlignment.Center
let labelFont = UIFont(name: helveticaFont(myFont.toRaw()), size: mySize)
let labelColor = UIColor.whiteColor()
let myAttributes :Dictionary = [NSParagraphStyleAttributeName : paragraphStyle,
NSKernAttributeName : 3, // (-1,5)
NSFontAttributeName : labelFont,
NSForegroundColorAttributeName : labelColor,
NSShadowAttributeName : shadow]
let myAttributedString = NSMutableAttributedString (string: myString, attributes:myAttributes)
// add new color
let secondColor = UIColor.blackColor()
let stringArray = myString.componentsSeparatedByString(" ")
let firstString: String? = stringArray.first
let letterCount = countElements(firstString!)
if firstString {
myAttributedString.addAttributes([NSForegroundColorAttributeName:secondColor], range:NSMakeRange(0,letterCount))
}
return myAttributedString
}
首先和最后一个扩展名,用于在字符串数组中查找范围:
extension Array {
var last: T? {
if self.isEmpty {
NSLog("array crash error - please fix")
return self [0]
} else {
return self[self.endIndex - 1]
}
}
}
extension Array {
var first: T? {
if self.isEmpty {
NSLog("array crash error - please fix")
return self [0]
} else {
return self [0]
}
}
}
新颜色:
extension UIColor {
class func shadowColor() -> UIColor {
return UIColor(red: 0.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 0.3)
}
class func textShadowColor() -> UIColor {
return UIColor(red: 50.0/255.0, green: 50.0/255.0, blue: 50.0/255.0, alpha: 0.5)
}
class func pastelBlueColor() -> UIColor {
return UIColor(red: 176.0/255.0, green: 186.0/255.0, blue: 255.0/255.0, alpha: 1)
}
class func pastelYellowColor() -> UIColor {
return UIColor(red: 255.0/255.0, green: 238.0/255.0, blue: 140.0/255.0, alpha: 1)
}
}
我的宏观替代者:
enum MyConstants: Float {
case CornerRadius = 5.0
}
我的按钮制造商带有文本:
func myButtonMaker (myView:UIView) -> UIButton {
let myButton = UIButton.buttonWithType(.System) as UIButton
myButton.backgroundColor = UIColor.pastelBlueColor()
myButton.showsTouchWhenHighlighted = true;
let myCGSize:CGSize = CGSizeMake(100.0, 50.0)
let myFrame = CGRectMake(myView.frame.midX - myCGSize.height,myView.frame.midY - 2 * myCGSize.height,myCGSize.width,myCGSize.height)
myButton.frame = myFrame
let myTitle = myAttributedText("Button",20.0,FontValue.FVLight)
myButton.setAttributedTitle(myTitle, forState:.Normal)
myButton.layer.cornerRadius = myButton.bounds.size.width / MyConstants.CornerRadius.toRaw()
myButton.setTitleColor(UIColor.whiteColor(), forState: .Normal)
myButton.tag = 100
myButton.bringSubviewToFront(myView)
myButton.layerGradient()
myView.addSubview(myButton)
return myButton
}
我的Uiview/Uilabel Maker带有归因的文本,阴影和圆角:
func myLabelMaker (myView:UIView) -> UIView {
let myFrame = CGRectMake(myView.frame.midX / 2 , myView.frame.midY / 2, myView.frame.width/2, myView.frame.height/2)
let mylabelFrame = CGRectMake(0, 0, myView.frame.width/2, myView.frame.height/2)
let myBaseView = UIView()
myBaseView.frame = myFrame
myBaseView.backgroundColor = UIColor.clearColor()
let myLabel = UILabel()
myLabel.backgroundColor=UIColor.pastelYellowColor()
myLabel.frame = mylabelFrame
myLabel.attributedText = myAttributedText("This is my String",20.0,FontValue.FVLight)
myLabel.numberOfLines = 5
myLabel.tag = 100
myLabel.layer.cornerRadius = myLabel.bounds.size.width / MyConstants.CornerRadius.toRaw()
myLabel.clipsToBounds = true
myLabel.layerborders()
myBaseView.addSubview(myLabel)
myBaseView.layerShadow()
myBaseView.layerGradient()
myView.addSubview(myBaseView)
return myLabel
}
通用影子添加:
func viewshadow<T where T: UIView> (shadowObject: T)
{
let layer = shadowObject.layer
let radius = shadowObject.frame.size.width / MyConstants.CornerRadius.toRaw();
layer.borderColor = UIColor.whiteColor().CGColor
layer.borderWidth = 0.8
layer.cornerRadius = radius
layer.shadowOpacity = 1
layer.shadowRadius = 3
layer.shadowOffset = CGSizeMake(2.0,2.0)
layer.shadowColor = UIColor.shadowColor().CGColor
}
查看的视图样式的扩展:
extension UIView {
func layerborders() {
let layer = self.layer
let frame = self.frame
let myColor = self.backgroundColor
layer.borderColor = myColor.CGColor
layer.borderWidth = 10.8
layer.cornerRadius = layer.borderWidth / MyConstants.CornerRadius.toRaw()
}
func layerShadow() {
let layer = self.layer
let frame = self.frame
layer.cornerRadius = layer.borderWidth / MyConstants.CornerRadius.toRaw()
layer.shadowOpacity = 1
layer.shadowRadius = 3
layer.shadowOffset = CGSizeMake(2.0,2.0)
layer.shadowColor = UIColor.shadowColor().CGColor
}
func layerGradient() {
let layer = CAGradientLayer()
let size = self.frame.size
layer.frame.size = size
layer.frame.origin = CGPointMake(0.0,0.0)
layer.cornerRadius = layer.bounds.size.width / MyConstants.CornerRadius.toRaw();
var color0 = CGColorCreateGenericRGB(250.0/255, 250.0/255, 250.0/255, 0.5)
var color1 = CGColorCreateGenericRGB(200.0/255, 200.0/255, 200.0/255, 0.1)
var color2 = CGColorCreateGenericRGB(150.0/255, 150.0/255, 150.0/255, 0.1)
var color3 = CGColorCreateGenericRGB(100.0/255, 100.0/255, 100.0/255, 0.1)
var color4 = CGColorCreateGenericRGB(50.0/255, 50.0/255, 50.0/255, 0.1)
var color5 = CGColorCreateGenericRGB(0.0/255, 0.0/255, 0.0/255, 0.1)
var color6 = CGColorCreateGenericRGB(150.0/255, 150.0/255, 150.0/255, 0.1)
layer.colors = [color0,color1,color2,color3,color4,color5,color6]
self.layer.insertSublayer(layer, atIndex: 2)
}
}
实际视图确实加载功能:
func buttonPress (sender:UIButton!) {
NSLog("%@", "ButtonPressed")
}
override func viewDidLoad() {
super.viewDidLoad()
let myLabel = myLabelMaker(myView)
let myButton = myButtonMaker(myView)
myButton.addTarget(self, action: "buttonPress:", forControlEvents:UIControlEvents.TouchUpInside)
viewshadow(myButton)
viewshadow(myLabel)
}
我认为这是一种非常方便的使用方式 regular expressions
找到应用属性的范围。这就是我这样做的方式:
NSMutableAttributedString *goodText = [[NSMutableAttributedString alloc] initWithString:articleText];
NSRange range = [articleText rangeOfString:@"\\[.+?\\]" options:NSRegularExpressionSearch|NSCaseInsensitiveSearch];
if (range.location != NSNotFound) {
[goodText addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Georgia" size:16] range:range];
[goodText addAttribute:NSForegroundColorAttributeName value:[UIColor brownColor] range:range];
}
NSString *regEx = [NSString stringWithFormat:@"%@.+?\\s", [self.article.titleText substringToIndex:0]];
range = [articleText rangeOfString:regEx options:NSRegularExpressionSearch|NSCaseInsensitiveSearch];
if (range.location != NSNotFound) {
[goodText addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Georgia-Bold" size:20] range:range];
[goodText addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:range];
}
[self.textView setAttributedText:goodText];
我正在搜索可用属性的列表,但在此处和课堂参考的第一页中没有找到它们。因此,我决定在此处发布有关此信息的信息。
属性字符串支持文本的以下标准属性。如果键不在字典中,请使用下面描述的默认值。
NSString *NSFontAttributeName;
NSString *NSParagraphStyleAttributeName;
NSString *NSForegroundColorAttributeName;
NSString *NSUnderlineStyleAttributeName;
NSString *NSSuperscriptAttributeName;
NSString *NSBackgroundColorAttributeName;
NSString *NSAttachmentAttributeName;
NSString *NSLigatureAttributeName;
NSString *NSBaselineOffsetAttributeName;
NSString *NSKernAttributeName;
NSString *NSLinkAttributeName;
NSString *NSStrokeWidthAttributeName;
NSString *NSStrokeColorAttributeName;
NSString *NSUnderlineColorAttributeName;
NSString *NSStrikethroughStyleAttributeName;
NSString *NSStrikethroughColorAttributeName;
NSString *NSShadowAttributeName;
NSString *NSObliquenessAttributeName;
NSString *NSExpansionAttributeName;
NSString *NSCursorAttributeName;
NSString *NSToolTipAttributeName;
NSString *NSMarkedClauseSegmentAttributeName;
NSString *NSWritingDirectionAttributeName;
NSString *NSVerticalGlyphFormAttributeName;
NSString *NSTextAlternativesAttributeName;
完整的参考是 这里.
该解决方案将适用于任何长度
NSString *strFirst = @"Anylengthtext";
NSString *strSecond = @"Anylengthtext";
NSString *strThird = @"Anylengthtext";
NSString *strComplete = [NSString stringWithFormat:@"%@ %@ %@",strFirst,strSecond,strThird];
NSMutableAttributedString *attributedString =[[NSMutableAttributedString alloc] initWithString:strComplete];
[attributedString addAttribute:NSForegroundColorAttributeName
value:[UIColor redColor]
range:[strComplete rangeOfString:strFirst]];
[attributedString addAttribute:NSForegroundColorAttributeName
value:[UIColor yellowColor]
range:[strComplete rangeOfString:strSecond]];
[attributedString addAttribute:NSForegroundColorAttributeName
value:[UIColor blueColor]
range:[strComplete rangeOfString:strThird]];
self.lblName.attributedText = attributedString;
我写了助手来轻松添加属性:
- (void)addColor:(UIColor *)color substring:(NSString *)substring;
- (void)addBackgroundColor:(UIColor *)color substring:(NSString *)substring;
- (void)addUnderlineForSubstring:(NSString *)substring;
- (void)addStrikeThrough:(int)thickness substring:(NSString *)substring;
- (void)addShadowColor:(UIColor *)color width:(int)width height:(int)height radius:(int)radius substring:(NSString *)substring;
- (void)addFontWithName:(NSString *)fontName size:(int)fontSize substring:(NSString *)substring;
- (void)addAlignment:(NSTextAlignment)alignment substring:(NSString *)substring;
- (void)addColorToRussianText:(UIColor *)color;
- (void)addStrokeColor:(UIColor *)color thickness:(int)thickness substring:(NSString *)substring;
- (void)addVerticalGlyph:(BOOL)glyph substring:(NSString *)substring;

您还可以通过Cocoapods安装: pod 'MASAttributes', '~> 1.0.0'
由于iOS 7,您可以使用 NSAttributedString
使用HTML语法:
NSURL *htmlString = [[NSBundle mainBundle] URLForResource: @"string" withExtension:@"html"];
NSAttributedString *stringWithHTMLAttributes = [[NSAttributedString alloc] initWithFileURL:htmlString
options:@{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType}
documentAttributes:nil
error:nil];
textView.attributedText = stringWithHTMLAttributes;// you can use a label also
您必须将文件“ String.html”添加到您的项目中,并且HTML的内容可以如下:
<html>
<head>
<style type="text/css">
body {
font-size: 15px;
font-family: Avenir, Arial, sans-serif;
}
.red {
color: red;
}
.green {
color: green;
}
.blue {
color: blue;
}
</style>
</head>
<body>
<span class="red">first</span><span class="green">second</span><span class="blue">third</span>
</body>
</html>
现在,您可以使用 NSAttributedString
如您所需的,即使没有HTML文件,例如:
//At the top of your .m file
#define RED_OCCURENCE -red_occurence-
#define GREEN_OCCURENCE -green_occurence-
#define BLUE_OCCURENCE -blue_occurence-
#define HTML_TEMPLATE @"<span style=\"color:red\">-red_occurence-</span><span style=\"color:green\">-green_occurence-</span><span style=\"color:blue\">-blue_occurence-</span></body></html>"
//Where you need to use your attributed string
NSString *string = [HTML_TEMPLATE stringByReplacingOccurrencesOfString:RED_OCCURENCE withString:@"first"] ;
string = [string stringByReplacingOccurrencesOfString:GREEN_OCCURENCE withString:@"second"];
string = [string stringByReplacingOccurrencesOfString:BLUE_OCCURENCE withString:@"third"];
NSData* cData = [string dataUsingEncoding:NSUTF8StringEncoding];
NSAttributedString *stringWithHTMLAttributes = [[NSAttributedString alloc] initWithData:cData
options:@{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType}
documentAttributes:nil
error:nil];
textView.attributedText = stringWithHTMLAttributes;
我总是发现与归因串一起工作是一个令人难以置信的长时间乏味的过程。
因此,我制作了一个为您创建所有代码的Mac应用程序。

使用属性字符串扩展名的更轻松的解决方案。
extension NSMutableAttributedString {
// this function attaches color to string
func setColorForText(textToFind: String, withColor color: UIColor) {
let range: NSRange = self.mutableString.range(of: textToFind, options: .caseInsensitive)
self.addAttribute(NSAttributedStringKey.foregroundColor, value: color, range: range)
}
}
尝试一下并查看(在Swift 3和4中进行了测试)
let label = UILabel()
label.frame = CGRect(x: 120, y: 100, width: 200, height: 30)
let first = "first"
let second = "second"
let third = "third"
let stringValue = "\(first)\(second)\(third)" // or direct assign single string value like "firstsecondthird"
let attributedString: NSMutableAttributedString = NSMutableAttributedString(string: stringValue)
attributedString.setColorForText(textToFind: first, withColor: UIColor.red) // use variable for string "first"
attributedString.setColorForText(textToFind: "second", withColor: UIColor.green) // or direct string like this "second"
attributedString.setColorForText(textToFind: third, withColor: UIColor.blue)
label.font = UIFont.systemFont(ofSize: 26)
label.attributedText = attributedString
self.view.addSubview(label)
这是预期的结果:
在Swift 4中:
let string:NSMutableAttributedString = {
let mutableString = NSMutableAttributedString(string: "firstsecondthird")
mutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.red , range: NSRange(location: 0, length: 5))
mutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.green , range: NSRange(location: 5, length: 6))
mutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.blue , range: NSRange(location: 11, length: 5))
return mutableString
}()
print(string)
您可以加载 HTML
归因于字符串 Swift
如下
var Str = NSAttributedString(
data: htmlstring.dataUsingEncoding(NSUnicodeStringEncoding, allowLossyConversion: true),
options: [ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType],
documentAttributes: nil,
error: nil)
label.attributedText = Str
加载a html
从文件
if let rtf = NSBundle.mainBundle().URLForResource("rtfdoc", withExtension: "rtf", subdirectory: nil, localization: nil) {
let attributedString = NSAttributedString(fileURL: rtf, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil, error: nil)
textView.attributedText = attributedString
textView.editable = false
}

并根据您所需属性设置字符串....遵循此。
http://makeapppie.com/2014/10/20/swift-swift-using-using-attributed-strings-in-swift/
我制作了一个使它容易得多的库。查看 zencopy。
您可以创建样式对象,和/或将它们设置为键以稍后引用。像这样:
ZenCopy.manager.config.setStyles {
return [
"token": Style(
color: .blueColor(), // optional
// fontName: "Helvetica", // optional
fontSize: 14 // optional
)
]
}
然后,您可以轻松构造字符串并将其定型并具有参数:)
label.attributedText = attributedString(
["$0 ".style("token") "is dancing with ", "$1".style("token")],
args: ["JP", "Brock"]
)
您还可以通过Regex搜索轻松塑造东西!
let atUserRegex = "(@[A-Za-z0-9_]*)"
mutableAttributedString.regexFind(atUserRegex, addStyle: "token")
这将以“代币”风格在其前面使用“@”样式。 (例如@jpmcglone)
我仍然需要使它有效 NSAttributedString
必须提供,但我认为 fontName
, fontSize
和颜色覆盖它的大部分。预计很快会有很多更新:)
如果需要,我可以帮助您开始。还要寻找反馈,因此,如果这使您的生活更轻松,我会说完成任务。
- (void)changeColorWithString:(UILabel *)uilabel stringToReplace:(NSString *) stringToReplace uiColor:(UIColor *) uiColor{
NSMutableAttributedString *text =
[[NSMutableAttributedString alloc]
initWithAttributedString: uilabel.attributedText];
[text addAttribute: NSForegroundColorAttributeName value:uiColor range:[uilabel.text rangeOfString:stringToReplace]];
[uilabel setAttributedText: text];
}
为了解决此类问题,我在Swift中创建了库,称为Atributika。
let str = "<r>first</r><g>second</g><b>third</b>".style(tags:
Style("r").foregroundColor(.red),
Style("g").foregroundColor(.green),
Style("b").foregroundColor(.blue)).attributedString
label.attributedText = str
你可以在这里找到它 https://github.com/psharanda/atributika

let attrBold:Dictionary = [NSAttributedStringKey.font : UIFont(name: "Raleway-SemiBold", size: 15)]
let attrBoldWithColor: Dictionary = [NSAttributedStringKey.font : UIFont(name: "Raleway-SemiBold", size: 15),
