双击隐藏UIPopoverController

Question

我有分割视图应用程序，当然在垂直细节视图中有一个弹出控制器，如何用双击隐藏？感谢

您必须添加doubleTap手势识别器并调用dismissPopoverAnimated:

首先声明一个手势识别器并将其配置为您的视图：

 UITapGestureRecognizer * doubleTapGesture = [[UIGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTapCallback:)];
 doubleTapGesture.numberOfTapsRequired = 2;
 [yourView addGestureRecognizer:doubleTapGesture];
 [doubleTapGesture release];

然后实现回调：

- (IBAction) doubleTapCallback: (UITapGestureRecognizer *) sender
{
    [yourPopOverController dismissPopoverAnimated:YES]

}
