iOS attributedText in UILabel 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];
