添加到 UIImageView 的点击手势没有响应

Question

我想让UIImageView 响应用户的点击。我在情节提要中添加图像视图，并为它们设置标签。然后在viewDidLoad:

UIGestureRecognizer *tapGesture = [[UIGestureRecognizer alloc] initWithTarget:self action:@selector(openCourseView:)];
[self.view viewWithTag:IMAGE_VIEW_TERM].userInteractionEnabled = YES;
[self.view viewWithTag:IMAGE_VIEW_1V1].userInteractionEnabled = YES;
[self.view viewWithTag:IMAGE_VIEW_SPECIAL].userInteractionEnabled = YES;

[[self.view viewWithTag:IMAGE_VIEW_TERM] addGestureRecognizer:tapGesture];
[[self.view viewWithTag:IMAGE_VIEW_1V1] addGestureRecognizer:tapGesture];
[[self.view viewWithTag:IMAGE_VIEW_SPECIAL] addGestureRecognizer:tapGesture];

但我的响应方法openCourseView: 从未调用过。然后我尝试使用IBOutlet 将手势识别器添加到图像视图，仍然没有响应。

有什么问题？

这是 LokeshChowdary 发现的一个错误。

在我的代码中，UIGestureRecognizer 应该是 UITapGestureRecognizer。
