iOS开发 添加全局右滑返回手势

1. 创建类 继承 UINavigationController

2.- (void)viewDidLoad {

    [super viewDidLoad];

    // 获取系统自带滑动手势的target对象

    id target = self.interactivePopGestureRecognizer.delegate;

    // 创建全屏滑动手势, 调用系统自带滑动手势target的action方法

   UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:target action:NSSelectorFromString(@"handleNavigationTransition:")];

    // 设置手势代理, 拦截手势触发

    pan.delegate=self;

    // 给导航控制器的View添加全屏滑动手势

    [self.view addGestureRecognizer:pan];

    //禁止使用系统自带的滑动手势

    self.interactivePopGestureRecognizer.enabled = NO;

}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer*)gestureRecognizer

{

    //如过是根视图 , 返回NO

    if (self.childViewControllers.count == 1) {

        returnNO;

    }

    return YES;

}

3.不要忘记签协议<UIGestureRecognizerDelegate> ,然后成功了, 然后快乐就行了
