我有一个像这样的NSAttributedString：
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"testing it out @clickhere"]; NSInteger length = str.length; [str addAttribute:NSForegroundColorAttributeName value:[UIColor bestTextColor] range:NSMakeRange(0,length)];
NSMutableAttributedString设置为UILabel,如下所示：
label.attributedText = str;
如何在另一个视图控制器中为上面的字符串中的’@clickhere’做出一个轻击手势(或可点击的东西)？
谢谢！
解决方法
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.
}
}
