需求:A控制器是我push过来的，我希望这个控制器只能点击导航条左边的返回按钮来pop，而侧边右滑动的手势pop我希望能把它禁用掉。当然其他控制器我希望不还是有这个pop的手势
在 A 控制器里写：
- (void)viewWillAppear:(BOOL)animated{
[superviewWillAppear:animated];
self.navigationController.interactivePopGestureRecognizer.delegate=self;
}
- (void)viewWillDisappear:(BOOL)animated{
[superviewWillDisappear:animated];
self.navigationController.interactivePopGestureRecognizer.delegate=nil;
}
// 给该控制器添加协议 - (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{
returngestureRecognizer !=self.navigationController.interactivePopGestureRecognizer;
}
