将手势识别器添加到导航栏

Question

我试图在导航栏上添加平移手势识别器：

[self.navigationController.navigationBar addGestureRecognizer:self.panGestureRecognizer];

但它似乎没有触发手势。有什么想法吗？

Answer 1

首先创建pangesture对象。 将手势识别器添加到导航栏视图。

然后调用您的手势识别器方法。

UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(pushVC:)];

[self.nav.view addGestureRecognizer:panGesture];


-(void)pushVC:(UIPanGestureRecognizer *)gesture
{
    if(gesture.state == UIGestureRecognizerStateEnded)
    {
        pushVC *pushvc = [[pushVC alloc] initWithNibName:@"pushVC" bundle:nil];

        [self.nav pushViewController:pushvc animated:YES];
    }
}
