iOS禁用系统侧滑返回手势

-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
if([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
}

• (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];
  if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
  self.navigationController.interactivePopGestureRecognizer.enabled = YES;
  }
  }

不管用画的用这个
id traget = self.navigationController.interactivePopGestureRecognizer.delegate;
UIPanGestureRecognizer * pan = [[UIPanGestureRecognizer alloc]initWithTarget:traget action:nil];
[self.view addGestureRecognizer:pan];
