我有一个NSAttributedString像这样：
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"testing it out @clickhere"];
NSInteger length = str.length;
[str addAttribute:NSForegroundColorAttributeName value:[UIColor bestTextColor] range:NSMakeRange(0,length)];
NSMutableAttributedString被设置为UILabel，如下所示：
label.attributedText = str;
如何为上方字符串中的'@clickhere'单词向另一个viewcontroller做出点击手势（或可点击的操作）？
谢谢！
我认为，最好的方法是将添加UIGestureRecognizer到您的文件UILabel并验证您想要的框架。
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, 0, 300, 44);
if(YES == CGRectContainsPoint(validFrame, touchPoint)
{
//Handle here.
}
}
