UITapGestureRecognizer 在 UIImageView 中不起作用 [英] UITapGestureRecognizer not working in UIImageView
本文介绍了UITapGestureRecognizer 在 UIImageView 中不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下代码:
UITapGestureRecognizer *showStoryTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showNewsStory:)];
[showStoryTapRecognizer setDelegate:self];
[self.storyImageView_ addGestureRecognizer:showStoryTapRecognizer];
[showStoryTapRecognizer release];
然而这并没有触发 showNewsStory，这是为什么呢?我在图像视图中启用了 userInteraction.
This however doesn't trigger the showNewsStory, why is this? I have enabled userInteraction in the image view.
推荐答案
UITapGestureRecognizer *oneTouch=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(OneTouchHandeler)];
[oneTouch setNumberOfTouchesRequired:1];
[imageView addGestureRecognizer:oneTouch];
imageView.userInteractionEnabled = YES;
