问题描述
在新的 iOS 7 UINavigationController 中，有一个滑动手势可以在视图之间切换.有没有办法检测或拦截手势?
In the new iOS 7 UINavigationController, there is a swipe gesture to switch between views.
Is there a way to detect or intercept the gesture?
推荐答案
交互式弹出手势识别器通过 UINavigationController 的 interactivePopGestureRecognizer 属性公开.您可以添加自己的控制器作为手势识别器的目标并做出适当的响应:
The interactive pop gesture recognizer is exposed through UINavigationController's interactivePopGestureRecognizer property. You can add your own controller as a target of the gesture recognizer and respond appropriately:
@implementation MyViewController
...
- (void)viewDidLoad
{
[super viewDidLoad];
[self.navigationController.interactivePopGestureRecognizer addTarget:self
action:@selector(handlePopGesture:)];
}
- (void)handlePopGesture:(UIGestureRecognizer *)gesture
{
if (gesture.state == UIGestureRecognizerStateBegan)
{
// respond to beginning of pop gesture
}
// handle other gesture states, if desired
}
...
@end
