如何從UIView導航到UIViewController

Question

我知道uiview沒有導航控件。因此，我無法將uiview推到下一個uview控制器。

這裏是我的方法的代碼。請幫忙。謝謝！

- (void)scrollViewDoubleTapped:(UITapGestureRecognizer*)recognizer { 
    CGPoint pointInView = [recognizer locationInView:self]; 
    NSLog(@"%f , %f",pointInView.x,pointInView.y); 

    if ((pointInView.x >= (231.0) && pointInView.x <=(293) && pointInView.y >= (193) && pointInView.y <=(218))) 
    { 

     // how to push to next viewcontroller here? 

     UIView *view = [UIGestureRecognizer view]; //what should i do for this code? 


     [self viewController]; 
    } 
} 

-(TestViewViewController*)viewController 
{ 
    for (UIView *next = [self superview]; next; next = next.superview) 
    { 
     UIResponder *nextResponder = [next nextResponder]; 

     if([nextResponder isKindOfClass:[TestViewViewController class]]) 
     { 

      return (TestViewViewController*)nextResponder; 
     } 
    } 

    return nil; 
}

如果你想獲得的ViewController具有視野比你可以使用nextResponder方法

所以首先你從gestureRecognizer的觀點：

UIView *view = [gestureRecognizer view]; 

，比搜索包含的視圖 - 控制查看

Look here

編輯：

if ((pointInView.x >= (231.0) && pointInView.x <=(293) && pointInView.y >= (193) && pointInView.y <=(218))) 
    { 

     // how to push to next viewcontroller here? 

     UIView *view = [recognizer view]; //what should i do for this code? 

     UIViewController *viewController = [self getViewControllerFromView:view]; 

     if(viewController) { 
      // do whatever you want... 
     UIViewController *newViewController = ... 
     [viewController.navigationController pushViewController:newViewController animated:YES]; 
     } 

    } 

... 我重寫方法得到的ViewController您的案件。從某些觀點得到它：

-(UIViewController*)getViewControllerFromView:(UIView*) view 
{ 
    if([[view nextResponder] isKindOfClass:[UIViewController class]]) 
    { 
     return (UIViewController*)[view nextResponder]; 
    } 
    else { 

     for (UIView *next = [view superview]; next; next = next.superview) 
     { 
      UIResponder *nextResponder = [next nextResponder]; 

      if([nextResponder isKindOfClass:[UIViewController class]]) 
      { 
       return (UIViewController*)nextResponder; 
      } 
     } 
    } 

    return nil; 
} 

新的編輯::

您EAGLView有@property (nonatomic, retain) UIViewController *viewController; ADD @synthesize viewController = _viewController;到.m文件。

CoreMotionAppDelegate ::

MainViewController * itemsViewController = [[MainViewController alloc]init]; 

    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:itemsViewController]; 
    glView.viewController = itemsViewController; 


    [glView startAnimation]; 
    [[self window]setRootViewController:navController]; 

，比你scrollViewDoubleTapped方法只是

EAGLView *v = (EAGLView*)[recognizer view]; 
UIViewController *viewController = v.viewController;
