iphone - UITapGestureRecognizer 在 UIImageView 中不工作

Question

我有以下代码:

UITapGestureRecognizer *showStoryTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showNewsStory:)];
[showStoryTapRecognizer setDelegate:self];
[self.storyImageView_ addGestureRecognizer:showStoryTapRecognizer];
[showStoryTapRecognizer release];

但这并没有触发 showNewsStory，这是为什么呢？我在 ImageView 中启用了 userInteraction。

Answer 1

您应该为 UIImageView 对象启用用户交互:

[self.storyImageView_ setUserInteractionEnabled:YES];

编辑:

尝试删除

[showStoryTapRecognizer setDelegate:self];

据我所知，我认为 UITapGestureRecognizer 没有它的委托(delegate)方法。
