方式一：
前提：如果使用的自定义UINavigationController基类，请不要在此基类里写相关的手势操作方法。
代码如下：
-(void)viewDidAppear:(BOOL)animated{
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
}
-(void)viewWillDisappear:(BOOL)animated{
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}
方式二：
流程：先设置代理---->重写手势操作方法
-(void)viewDidAppear:(BOOL)animated{
self.navigationController.interactivePopGestureRecognizer.delegate = self;
}
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer
*)gestureRecognizer{
return NO; //YES：允许右滑返回 NO：禁止右滑返回
}
