iOS7返回手势的开启与禁用

1. 在有的时候，我们不需要手势返回功能，那么可以在页面中添加以下代码：  

[objc]
view plaincopyprint?

- (void)viewDidAppear:(BOOL)animated  

{  

    [super viewDidAppear:animated];  

  

    // 禁用 iOS7 返回手势  

    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {  

        self.navigationController.interactivePopGestureRecognizer.enabled = NO;  

    }  

}  

  

- (void)viewWillDisappear:(BOOL)animated  

{  

    [super viewWillDisappear:animated];  

  

    // 开启  

    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {  

        self.navigationController.interactivePopGestureRecognizer.enabled = YES;  

    }  

}
