Question

我要做的是在scrollBar上方放置一个滚动视图，但仍然有导航栏获取触摸输入。

我看了响应链，看起来似乎没有。

FowardScrollView* _scrollView = [[FowardScrollView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 480.0f, 40.0f)];


UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController: [[UIViewController alloc] init] ];
navController.topViewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"hello world" style:UIBarButtonItemStylePlain target:nil action:nil];
[navController.view setFrame:self.view.frame];
[self.view addSubview: navController.view];

[self.view addSubview: _scrollView];

然后在前视图的imp

中

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{

    [self.nextResponder touchesBegan:touches withEvent:event];
//    [super touchesBegan:touches withEvent:event];
}

如果您需要了解实际的触摸事件，比如说，将其转发到导航栏，您可以始终覆盖UIApplication及其触摸处理方法。

ScrollView触摸转发到UINavigationController
