iphone - 在触摸事件中获取自定义 SuperView？

Question

我正在开发一个小游戏，我想在 super View 上做一些功能.. super View 是一个自定义类，即 Reflection View..并希望在用户移动 View 时隐藏反射..

这是我所做的..(查看代码中的注释了解详情)

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesBegan:touches withEvent:event];
    NSLog(@"Touch Began");
    frame2 = dragImageView1.frame;
     NSLog(@"uiview origin: %@", NSStringFromCGPoint(frame2.origin));
     // here i want to get the superview Programatically because i will work on multiple such views and [touch view].superview does not give me the ReflectionView Functions
     [_reflectionView1 hideReflection];
    UITouch *touch = [[event allTouches] anyObject];


      if ([[touch view] tag]!=0) {
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        [[touch view] setFrame:CGRectMake(frame2.origin.x, frame2.origin.y, 125.0 * 1.1, 135.0 * 1.1)];
    } else {
        [[touch view] setFrame:CGRectMake(frame2.origin.x, frame2.origin.y, 52.08 * 1.1, 63.28 * 1.1)];
    }
        [self.view bringSubviewToFront:[touch view].superview]; 
      }
}

如 0x7fffff 所述，您需要将 super View 转换为自定义 View 。喜欢

[(ReflectionView *)touch.view.superview updateReflection];

如果您确定在父 View 始终是 ReeflectionView 的地方调用它，则使用此方法，否则如果您在父 View 不是反射的地方使用它，您的应用程序将崩溃。然后将其添加到您的代码中

if(touch.view.superview isEqual:[ReflectionView class])
{
   [(ReflectionView *)touch.view.superview updateReflection];
}
