如何在 iPhone 中喜欢这张图片？任何人都可以帮助我。我应该使用核心动画还是文本核心还是其他？ http://s7.postimage.org/qgbhw7c3v/Capture.png

Answer 1

    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);    

注意 => 在项目中添加CoreText框架并导入。
