QMUI中添加全屏手势,如果你使用了QM中的导航,是与FDFullscreenPopGesture存在冲突的,隐藏导航的处理冲突,FD会展示出导航,两者只能选其一,具体处理如下:

参考:

github.com/Tencent/QMU… github.com/Tencent/QMU…

1. 添加全屏手势

-(void)viewDidLoad{

    [super viewDidLoad];
        //这里需要注意:如果没有使用QM ,target=self.interactivePopGestureRecognizer.delegate

    id target = self.qmui_interactivePopGestureRecognizerDelegate;

    SEL handler = NSSelectorFromString(@"handleNavigationTransition:");

    // 获取添加系统边缘触发手势的View

    UIView *targetView = self.interactivePopGestureRecognizer.view;

    // 创建pan手势 作用范围是全屏

    UIPanGestureRecognizer *fullScreenGesture = [[UIPanGestureRecognizer alloc]initWithTarget:target action:handler];

    fullScreenGesture.delegate = self;

    [targetView addGestureRecognizer:fullScreenGesture];

    self.fullScreenGesture = fullScreenGesture;

    // 关闭边缘触发手势 防止和原有边缘手势冲突(不关闭处理过程中发现很多问题,直接给关闭了)

    [self.interactivePopGestureRecognizer setEnabled:NO];
}

2.添加手势代理处理

// iOS 13.4 开始会优先询问该方法，只有返回 YES 后才会继续后续的逻辑(这里我没有做特殊处理)

- (BOOL)_gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveEvent:(UIEvent *)event {

    return YES;
}

//这里处理手势逻辑
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {

    //这里由于是替代interactivePopGestureRecognizer 所以只识别右滑返回
    if (gestureRecognizer == self.fullScreenGesture) {

        CGPoint translation = [self.fullScreenGesture translationInView:self.fullScreenGesture.view];

        if (translation.x > 0) {

            //判断是否可以向右滑
            BOOL canPopViewController = [self canPopViewController:self.topViewController byPopGesture:YES];
            
            if (canPopViewController) return YES;

        }

        return NO;

    }

    return YES;

}

- (BOOL)canPopViewController:(UIViewController *)viewController byPopGesture:(BOOL)byPopGesture {

    if (self.viewControllers.count > 1) {

        //判断是否有拦截返回QMUI方法shouldPopViewControllerByBackButtonOrPopGesture,如果自定义方法也可以,不需要拦截情况下只判断self.viewControllers.count > 1 即可返回YES 

        if ([viewController respondsToSelector:@selector(shouldPopViewControllerByBackButtonOrPopGesture:)] &&

            [viewController shouldPopViewControllerByBackButtonOrPopGesture:byPopGesture] == NO) {

            return NO;
        }
        return YES;
    }
    return NO;
}
