iOS Dev (4) 用TTTAttributedLabel创建变化丰富的UILabel

1. 不同颜色的字段混合在一个Label里怎么实现？

TTTAttributedLabel

TTTAttributedLabel *hintLabel1 = [[TTTAttributedLabel alloc] initWithFrame:CGRectMake(10.0, 10.0, 300, 30.0)];
[hintLabel1 setNumberOfLines:2];
[hintLabel1 setFont:[UIFont systemFontOfSize:12.0f]];
[hintLabel1 setBackgroundColor:[UIColor clearColor]];
[hintLabel1 setTextAlignment:NSTextAlignmentLeft];
[hintLabel1 setLineBreakMode:NSLineBreakByWordWrapping];
NSMutableAttributedString *hintString1 = [[NSMutableAttributedString alloc] initWithString:@"今天是个好日子。"];
[hintString1 addAttribute:(NSString *)kCTForegroundColorAttributeName value:(id)[[UIColor blueColor] CGColor] range:NSMakeRange(3,3)];
[hintLabel1 setText:hintString1];
[self.view addSubview:hintLabel1];
