大佬教程收集整理的这篇文章主要介绍了在外部点击iOS 8上关闭模式表格表视图,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@SELEctor(handleTapBehind:)]; [recognizer setnumberOfTapsrequired:1]; recognizer.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [self.view.window addGestureRecognizer:recognizer]; - (void)handleTapBehind:(UITapGestureRecognizer *)sender { if (sender.state == UIGestureRecognizerStateEnded) { CGPoint LOCATIOn = [sender LOCATIOnInView:nil]; //Passing nil gives us coordinates in the window //Then we convert the tap's LOCATIOn into the local view's coordinate system,and test to see if it's in or outside. If outside,dismiss the view. if (![self.view poinTinside:[self.view convertPoint:LOCATIOn fromView:self.view.window] withEvent:nil]) { // Remove the recognizer first so it's view.window is valid. [self.view.window removeGestureRecognizer:sender]; [self dismissModalViewControllerAnimated:YES]; } } }
但是它没有检测到外部视图点击,任何建议?
我通过添加UIGestureRecognizerDelegate协议和实现来解决这个问题
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer*)otherGestureRecognizer { return YES; }
另外,别忘了注册代表
recognizer.delegate = self;
现在,手势识别器应该识别手势,并且将调用目标方法(handleTapBehind :)。
这是iOS 8中的第二个问题:LOCATIOnInView:如果将nil作为视图传递,似乎不考虑设备方向。相反,传递根视图是有效的。
这是我的目标代码,似乎适用于iOS 7.1和8.0:
if (sender.state == UIGestureRecognizerStateEnded) { UIView *rootView = self.view.window.rootViewController.view; CGPoint LOCATIOn = [sender LOCATIOnInView:rootView]; if (![self.view poinTinside:[self.view convertPoint:LOCATIOn fromView:rootView] withEvent:nil]) { [self dismissviewControllerAnimated:YES completion:^{ [self.view.window removeGestureRecognizer:sender]; }]; } }
