ios - UIlabel 中的 UITapGestureRecognizer 错误

Question

我在 UILabel 上使用 UITapGestureRecognizer。

但是当我点击UILabel时它崩溃了。

以下是我的代码。

UITapGestureRecognizer *gester = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(moveToDetail:)];
gester.numberOfTapsRequired = 1;
[label addGestureRecognizer:gester];
label.userInteractionEnabled = YES;

以下是moveToDetail方法

- (void)moveToDetail:(id)sender {
}

以下是崩溃消息

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITapGestureRecognizer rootViewIfClass:]: unrecognized selector sent to instance

如何解决这个问题。

试试这个代码

UITapGestureRecognizer *gester = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(moveToDetail)];
gester.numberOfTapsRequired = 1;
label.userInteractionEnabled = YES;
[label addGestureRecognizer:gester];

- (void)moveToDetail
{

}
