ios – 为UILabel的一部分添加点击手势

NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"testing it out @clickhere"];
NSInteger length = str.length;
[str addAttribute:NSForegroundColorAttributeName value:[UIColor bestTextColor] range:NSMakeRange(0,length)];

label.attributedText = str;

我认为,最好的方法是将UIGestureRecognizer添加到您的UILabel并验证您想要的帧.

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
[_yourLabel addGestureRecognizer:singleTap];

- (void)handleTap:(UITapGestureRecognizer *)tapRecognizer
{
    CGPoint touchPoint = [tapRecognizer locationInView: _yourLabel];

    //Modify the validFrame that you would like to enable the touch
    //or get the frame from _yourLabel using the NSMutableAttributedString,if possible
    CGRect validFrame = CGRectMake(0,300,44);

    if(YES == CGRectContainsPoint(validFrame,touchPoint)
     {
        //Handle here.
     }
}
