两个视图控制器的TouchesMoved方法 [英] TouchesMoved method for two view controllers

问题描述

在我的应用中，有两个视图控制器.我在两个视图控制器中都编写了touchesmoved方法.但是，即使我触摸模拟器上的第二个视图控制器，也会调用第一个VC touches移动的方法.

In my app there are two view controllers. I wrote touchesmoved method in both the view controllers. But even if i touch on second view controller on simulator, the first VC touches moved method is called.

//VCOne

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"first view vc move method");

     UIStoryboard *storyboard = self.storyboard;
     ThreadedView *secViewController = [storyboard instantiateViewControllerWithIdentifier:@"threaded"];
     [self.view addSubview:secViewController.view];

     [self viewDidUnload];
}

因此，一旦调用了上述方法，它将导航到第二个视图控制器"ViewDIDLoad"方法.在这个文件中，我还写了另一种感动的方法.

So once the above method is called, it will navigate to second view controllers "ViewDIDLoad" method. In this file, i have written one more touches moved method.

//VCTwo

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"second view vc move method");
}

现在，如果我在第二个视图控制器中进行触摸，则将调用第一个VC touches方法，而不是第二个VC touches方法.

Now if i touch in second view controller, the first VC touchesmethod is called instead of second VC touches method.

有没有办法做到这一点?我需要针对不同的视图控制器使用不同的touched移动方法.

Is there any way to do this? I needed different touches moved method for different view controllers.

推荐答案

如果您要从第一个视图控制器过渡到第二个视图控制器， 您可以尝试以下方法:presentModalViewController:animated:.

If you want to transit from first view controller to second view controller, you can try this method: presentModalViewController:animated:.

在第一个视图控制器的touchesMoved:withEvevt:中

In your touchesMoved:withEvevt: of first view controller

NSLog(@"first view vc move method");

UIStoryboard *storyboard = self.storyboard;
ThreadedView *secViewController = [storyboard instantiateViewControllerWithIdentifier:@"Threaded"];
[self presentModalViewController:secViewController animated:NO];

在第二个视图控制器中，您可以使用dismissModalViewControllerAnimated:返回第一个视图控制器.

In second view controller, you can use dismissModalViewControllerAnimated: to go back to first view controller.
