IOS 自定义返回按钮 滑动返回假死解决方法

1、自定义返回按钮

2、添加滑动返回操作后出现假死现象

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    // 滑动返回
    self.interactivePopGestureRecognizer.enabled = YES;
    self.interactivePopGestureRecognizer.delegate = self;
}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
    return self.childViewControllers.count > 1;
}
