iOS 7 禁用向后滑动

Question

在 iOS 应用中，有一个从左边缘向右滑动的默认手势，应用 navigationController 将弹出视图控制器。

但是有没有办法为特定视图禁用它？

Answer 1

您可以通过公共 API 禁用它，请参阅 UINavigationController Class Reference

  //iOS7 Customization, swipe to pop gesture
  if ([navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
      navigationController.interactivePopGestureRecognizer.enabled = NO;
  }

此外，您可以在需要时切换回之前的状态

Answer 2

if(navigationController) {
  if ([navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
    navigationController.interactivePopGestureRecognizer.enabled = NO;
  }
}

Answer 3

有可能，但可能会导致您的应用被拒绝

-(void) viewWillAppear:(BOOL)animated 
{
    [super viewWillAppear:animated];
    self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
