You can do this by using CAtextLayer with string attributes.... — Venk, Dec 06 '12 at 06:34

You can use `NSAttributedString` to do this. You no longer need any other work around. — iDev, Dec 06 '12 at 06:40

    NSString *test = @"How can i Do that? (just only one string and don't devided into 2 part)";

    CFStringRef string =  (CFStringRef) test;
    CFMutableAttributedStringRef attrString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 0);
    CFAttributedStringReplaceString (attrString,CFRangeMake(0, 0), string);



    /*
     Note: we could have created CFAttributedStringRef which is non mutable, then we would have to give all its
     attributes right when we create it. We can change them if we use mutable form of CFAttributeString.
     */




    CGColorRef _red=[UIColor redColor].CGColor;

    CFAttributedStringSetAttribute(attrString, CFRangeMake(0, 11),kCTForegroundColorAttributeName, _red);

Note => Add CoreText framework in the project and import it.

i want to change each pixcel of letter in sentence, for example, letter "A", I just only want to change red color for 1/2 part of letter "A", how can I do that? – hackchick Dec 06 '12 at 07:13
here if you want to multicolor every letter then you wan use this logic dude.. just set color with image using this [UIColor colorWithPatternImage:[UIImage imageNamed:@""]]; try it just implement it and change some code – Paras Joshi Dec 06 '12 at 07:23

yah, my idea is build an basic karaoke app. Lyric will show and color will change of each pixcel of letter, like this http://www.youtube.com/watch?v=MZxvu2sXzug, but I don't know I should use Core Animation, Core Text or Quazt 2D, it is very hard for me, i'm newbie in Xcode and I from Vietnam so translate document write by English maybe hard for me :( – hackchick Dec 06 '12 at 07:32
after some time you'll also master in xcode and iphone if you love to your this work dude.. :) – Paras Joshi Dec 06 '12 at 07:34
