如何从窗口中删除视图？
我使用 Cocos2D 作为我的主要框架。在某些情况下，我希望 Cocos2D 加载 nib 文件并将其作为视图：
window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
TargetPlayerViewController *myController = [[TargetPlayerViewController alloc]initWithNibName:@"TargetPlayerViewController" bundle:nil];
[window addSubview:[myController view]];
[window makeKeyAndVisible];
这按预期工作，并显示 TargetPlayerViewController。精彩的！
我需要知道的是：加载该视图后，如何让视图自行删除？我尝试了几种不同的方法，但所有方法都会导致程序崩溃。
为了测试，我在视图上设置了一个按钮来触发此方法：
- (IBAction)GTFOnow:(id)sender {
NSLog(@"GFTO");
//window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
//[self.view removeFromSuperview];
//[window makeKeyAndVisible];
}
GTFOnow 是 TargetPlayerViewController 中的一个方法。当它被调用时，当前的子视图（在上面的 Cocos2D 代码中调用）应该从窗口中删除。
I am using Cocos2D for my main framework. In some cases, I want Cocos2D to load a nib file and have that be the view:
window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
TargetPlayerViewController *myController = [[TargetPlayerViewController alloc]initWithNibName:@"TargetPlayerViewController" bundle:nil];
[window addSubview:[myController view]];
[window makeKeyAndVisible];
This works as expected, and shows the TargetPlayerViewController. Wonderful!
What I need to know is: once that view has been loaded, how can I have the view remove itself? I've tried a few different ways, but all of them result in the program crashing.
To test I have a button on the view set up which triggers this method:
- (IBAction)GTFOnow:(id)sender {
NSLog(@"GFTO");
//window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
//[self.view removeFromSuperview];
//[window makeKeyAndVisible];
}
GTFOnow is a method in TargetPlayerViewController. When it is called, the current subview (that was called in the Cocos2D code above) should be removed from the window.

首先，您不应该仅仅因为要删除子视图而创建新窗口。其次，无论发生其他情况，都不会导致应用程序崩溃。您在哪一堂课上有
GTFOnow方法？我想在TargetPlayerViewController类中？First of all, you shouldn't create a new window just because you want to remove a subview. Secondly, whatever else happens, this shouldn't cause the app to crash. In which class do you have the
GTFOnowmethod? I suppose in theTargetPlayerViewControllerclass?
