在UISearchBar上更改光标颜色而不更换TintColor

Question

我希望我的搜索栏的色调颜色为白色（意味着取消按钮是白色的）。当色调为白色时，光标不可见。有没有办法分别设置光标颜色？

Answer 1

将颜色设置为要取消按钮的颜色，然后使用 UIAppearance协议更改文本字段上的色调颜色为您希望光标的颜色。前：

[self.searchBar setTintColor:[UIColor whiteColor]];                
[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setTintColor:[UIColor darkGrayColor]];

.

Answer 2

如果你喜欢功能，但令人讨厌的单行队员在Swift中，我有enjamin的循环到这个：

searchController.searchBar.tintColor = UIColor.whiteColor()

searchController.searchBar.subviews[0].subviews.flatMap(){ $0 as? UITextField }.first?.tintColor = UIColor.blueColor()

.

Answer 3

swift 3.0和4版本

searchController.searchBar.tintColor = .white        
UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).tintColor = .black

.

请注意，搜索栏不能是可选的。

Answer 4

Compact Swift 2.0解决方案使用 for-其中语法（无需断开循环）：

// Make SearchBar's tint color white to get white cancel button.
searchBar.tintColor = UIColor.white()

// Loop into it's subviews and find TextField, change tint color to something else.
for subView in searchBar.subviews[0].subviews where subView.isKindOfClass(UITextField) {
        subView.tintColor = UIColor.darkTextColor()
}

.

Answer 5

searchBar.tintColor = [UIColor whiteColor];
searchBar.backgroundColor = [UIColor clearColor];
for ( UIView *v in [searchBar.subviews.firstObject subviews] )
{
    if ( YES == [v isKindOfClass:[UITextField class]] )
    {
        [((UITextField*)v) setTintColor:[UIColor blueColor]];
        break;
    }
}

.

Answer 6

这似乎也在迅速推动我。

    searchController.searchBar.tintColor = UIColor.whiteColor()
    UITextField.appearanceWhenContainedInInstancesOfClasses([searchController.searchBar.dynamicType]).tintColor = UIColor.blackColor()

.

Answer 7

对于那些希望在SWIFT中做同样的事情，这是一个解决方案，我在很多麻烦后来了accros：

override func viewWillAppear(animated: Bool) {
    self.searchBar.tintColor = UIColor.whiteColor()

    let view: UIView = self.searchBar.subviews[0] as! UIView
    let subViewsArray = view.subviews

    for (subView: UIView) in subViewsArray as! [UIView] {
        println(subView)
        if subView.isKindOfClass(UITextField){
            subView.tintColor = UIColor.blueColor()
        }
    }

}

.

Answer 8

我只会使用以下代码添加到UisearchBar的扩展。

extension UISearchBar {
    var cursorColor: UIColor! {
        set {
            for subView in self.subviews[0].subviews where ((subView as? UITextField) != nil) {
                subView.tintColor = newValue
            }
        }
        get {
            for subView in self.subviews[0].subviews where ((subView as? UITextField) != nil) {
                return subView.tintColor
            }
            // Return default tintColor
            return UIColor.eightBit(red: 1, green: 122, blue: 255, alpha: 100)
        }
    }
}

.

Answer 9

IOS 9及更高版本

为取消按钮和文本域设置TintColor的最简单方法，使用以下方式：

[self.searchBar setTintColor:[UIColor whiteColor]];
[[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTintColor:UIColor.blueColor];

.

Answer 10

这是最简单的解决方案。

let textField = self.searchBar.value(forKey: "searchField") as! UITextField

    textField.tintColor = UIColor.white

.

Answer 11

在swift 5中最简单5：

    UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).tintColor = .black

.

Answer 12

这里是Felipe答案的“功能”版本（SWIFT 4.2）

// Make SearchBar's tint color white to get white cancel button.
searchBar.tintColor = .white

// Get the TextField subviews, change tint color to something else.
if let textFields = searchBar.subviews.first?.subviews.compactMap({ $0 as? UITextField }) {
        textFields.forEach { $0.tintColor = UIColor.darkGray }
}
