Run Code Online (Sandbox Code Playgroud) 我想UIWindow用以下代码添加一个视图:
AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
UIWindow *window = delegate.window;
UIView *aView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
aView.backgroundColor = [UIColor blackColor];
[window addSubview:aView];

这段代码不起作用.我想克隆UIAlertView的属性.当我们调用[alertViewInstance show];方法时,它会弹出一切
.
试过这个:
UIView *aView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
UIWindow* window = [UIApplication sharedApplication].keyWindow;
if (!window) {
window = [[UIApplication sharedApplication].windows objectAtIndex:0];
}
[window addSubview:aView];
[window bringSubviewToFront:aView];

我修复了根据约束更新帧的问题.选择下图中的第一个选项.但是,当我重新打开Xcode时,同样的问题一再出现.我必须一直重做它.是什么导致了这个问题以及如何解决它?

我有一个Kotlin代码:

if (AdsPrefs.shouldShowInterstitialAd()) {
mInterstitialAd.show()
this.callback = callback

现在,我想从Java类中调用此方法。我对如何称呼它感到困惑。这是我尝试过的
showAdWithCallback(() -> {
return null;

在应用程序视图层次结构中的所有视图上添加模式视图。
但这给我带来了问题。有时会按预期添加子视图,但有时不起作用。在哪种情况下,这将行不通,并且是在像UIAlertView这样的视图层次结构中添加模态视图的最佳方法是什么。
