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框架并导入它。
