Question

I’m creating iOS app that has a label. I want to set two colors. One for first part and other color for remaining part.
I’ve seen some messages in Stack over flow that, TTTAttributedLabel has the ability to set more than one color to text. My text will be like “ABC > def”. For “ABC”, i want to set brown color and for “def”, i want to set white color.
How can I set that?

Answer 1

NSString* text = @"ABC > def";
attributedLabel = [[[TTTAttributedLabel alloc] initWithFrame:frame] autorelease];
attributedLabel.numberOfLines = 0;
attributedLabel.lineBreakMode = UILineBreakModeWordWrap;
attributedLabel.fontColor = [UIColor brownColor];
[attributedLabel setText:text afterInheritingLabelAttributesAndConfiguringWithBlock:^(NSMutableAttributedString *mutableAttributedString) {
    NSRange whiteRange = [text rangeOfString:@"def"];
    if (whiteRange.location != NSNotFound) {
    // Core Text APIs use C functions without a direct bridge to UIFont. See Apple's "Core Text Programming Guide" to learn how to configure string attributes.
        [mutableAttributedString addAttribute:(NSString *)kCTForegroundColorAttributeName value:(id)[UIColor whiteColor].CGColor range:whiteRange];
    }

    return mutableAttributedString;
}];

[attributedLabel sizeToFit]; //this may not be needed if the frame provided is large enough

That searches for “def” in your string and sets the foreground color of the text to white for that range. Hope this helps. I only just learned this yesterday. Came across your question whilst trying to figure it out for myself.
