attributedText in UILabel

Introduction#

The current styled text that is displayed by the label.

You can add HTML text in UILabel using attributedText property or customized single UILabel text with different property

HTML text in UILabel

NSString * htmlString = @"<html><body> <b> Example bold text in HTML </b> </body></html>";
NSAttributedString * attrStr = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];

UILabel * yourLabel = [[UILabel alloc] init];
yourLabel.attributedText = attrStr;

Set different property to text in single UILabel

The first step you need to preform is to create a NSMutableAttributedString object. The reason we create a NSMutableAttributedString instead of NSAttributedString is because it enables us to append string to it.

NSString *fullStr = @"Hello World!";
NSMutableAttributedString *attString =[[NSMutableAttributedString alloc]initWithString:fullStr];

// Finding the range of text.
NSRange rangeHello = [fullStr rangeOfString:@"Hello"];
NSRange rangeWorld = [fullStr rangeOfString:@"World!"];

// Add font style for Hello
[attString addAttribute: NSFontAttributeName
                  value: [UIFont fontWithName:@"Copperplate" size:14]
                  range: rangeHello];
// Add text color for Hello
[attString addAttribute: NSForegroundColorAttributeName
                  value: [UIColor blueColor]
                  range: rangeHello];

// Add font style for World!
[attString addAttribute: NSFontAttributeName
                  value: [UIFont fontWithName:@"Chalkduster" size:20]
                  range: rangeWorld];
// Add text color for World!
[attString addAttribute: NSForegroundColorAttributeName
                  value: [UIColor colorWithRed:(66.0/255.0) green:(244.0/255.0) blue:(197.0/255.0) alpha:1]
                  range: rangeWorld];

// Set it to UILabel as attributedText
UILabel * yourLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 150, 200, 100)];
yourLabel.attributedText = attString;
[self.view addSubview:yourLabel];
