How to display the copyright icon in UILabel text?

StackOverflow https://stackoverflow.com/questions/1614689

Question

Does any one know how to display the copyright icon in UILabel text? This is the icon with a circle around c. The html code for it is: © or ©.

I tried the following code:

UILabel *contactInfo = [[UILabel alloc] initWithFrame:CGRectMake(-55,135,420,100)];
contactInfo.text = @"'©):'2009 Nationwide ";

or

contactInfo.text = @"'©'2009 Nationwide ";

or

contactInfo.text = @"©2009 Nationwide ";

It just prints everything as text and no icon.

This would work in a webView but I need it as UILabel text. Any help?

Was it helpful?

Solution

If your source files are in UTF-8, what they should be, this should work just fine. Otherwise you should use .strings-files in combination with the NSLocalizedString() macro and put your text into UTF-16 files.

Works for me: myUILabel.text = @"© by me";

© by me

Edit: Now that I see that you've tried to insert the symbol as HTML entity - this does not work, just insert the symbol as it appears.

OTHER TIPS

In interface builder try Option and G together.

If you don't have an Option key, try with ALT.

Another way to insert symbols without dealing with your source files' character encoding is to encode them as UTF-8 bytes using \x escapes.

According to Fileformat.info, the Copyright sign in UTF-8 bytes is 0xC2 0xA9.

So this works: @"\xC2\xA9 Nationwide"

That's how I do all of mine.

Copy and paste the copyright symbol © directly into your source code.

It's usually not a great idea to put non-ASCII strings through the compiler. The UTF-8 approach is thus better, if unreadable. You could use

NSLocalizedString(@"copyright", @"");

and then a .strings file with

copyright = "©2009";

would be a lot easier to generalize to other non-ASCII strings.

(BTW, it's option + g, not option + c.)

From iOS6> we can use NSAttributedString concept. Please see the below code snippet. Please ignore if anyone already aware of this. 

static NSString *html =
    @"<html>"
    "  <body>Here is copyright &copy; </i></body>"
    "</html>";

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 280, 300, 200)];
    NSError *err = nil;
    label.attributedText =
    [[NSAttributedString alloc]
     initWithData: [html dataUsingEncoding:NSUTF8StringEncoding]
     options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType }
     documentAttributes: nil
     error: &err];
    if(err)
        NSLog(@"Unable to parse label text: %@", err);
