Question

公司APP类似Uber,从最左侧滑动会出现菜单,但需要用到地图,添加全屏的tap手势会产生冲突,求大神支招,如何结局啊?急急急

Answer 1

Do you want it to only work if you swipe right from the left edge of the screen? If so, adding an edge gesture will do the trick! As follows:

- (void)viewDidLoad {
    [super viewDidLoad];
    
    UIScreenEdgePanGestureRecognizer* screenEdgePan = [[UIScreenEdgePanGestureRecognizer alloc]initWithTarget:self action:@selector(action:)];
    screenEdgePan.edges = UIRectEdgeLeft;
    [self.view addGestureRecognizer:screenEdgePan];
 
}
    
-(void)action:(UIScreenEdgePanGestureRecognizer*)sender{
    if (sender.edges == UIRectEdgeLeft) {
        NSLog(@"正在从左边滑动");
        switch (sender.state) {
            case UIGestureRecognizerStateBegan:
                NSLog(@"手势开始");
                break;
            case UIGestureRecognizerStateChanged:
                NSLog(@"手势进行中");
                break;
            case UIGestureRecognizerStateEnded:
                NSLog(@"手势结束");
                break;
                
            default:
                break;
        }
        
    }
}

I don’t know ios, but in Android it can be limited by judging the x coordinate position of the first point. This is just an idea, I haven’t tried it. I wonder if there is a similar idea for ios
