textViewDelegate代理里面有个url点击跳转的回调，- (BOOL)textView:(UITextView*)textView shouldInteractWithURL:(NSURL*)URL inRange:(NSRange)characterRange；我们在UITextView里面做一些超链接特别好用。但是在8/9系统上要触发这个回调是需要一种特殊的手势-->点击并按住，普通的tap事件根本触发不了它，那么怎么解决呢？
Add your tap recognizer:
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(addGestureRecognizer:)];
[myTextView addGestureRecognizer:tapRecognizer];
实现对应的方法即可：
- (void)addGestureRecognizer:(UIGestureRecognizer*)gestureRecognizer
{
if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]])
{
UITextView* textView = (UITextView*)gestureRecognizer.view;
CGPoint tapLocation = [gesture RecognizerlocationInView:textView];
UITextPosition*textPosition = [textView closestPositionToPoint:tapLocation];
NSDictionary *attributes = [textView textStylingAtPosition:textPosition inDirection:UITextStorageDirectionForward];
NSURL*url = attributes[NSLinkAttributeName];
if(url) {
NSRangerange = [self.text rangeOfString:@“xxx”];
if([self.delegateconformsToProtocol:@protocol(UITextViewDelegate)] && [self.delegaterespondsToSelector:@selector(textView:shouldInteractWithURL:inRange:)]) {
[self.delegate textView:self shouldInteractWithURL:url inRange:range];
}
}
}
[super addGestureRecognizer:gestureRecognizer];
}
