我的观点是显示y = -20 dispite，其框架设置为y = 0。旋转后，它会快速回到y = 0 [英] My view is displaying y=-20 dispite its frame set to y=0. After rotation it snaps back to y=0

问题描述

我开始创建一个基于通用窗口的应用程序。从iPhone版开始，我创建了一个UIViewController和相关的nib。

I started by creating a universal window based app. Starting with the iPhone version I created a UIViewController and associated nib.

我的应用代表：

rootViewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
[window makeKeyAndVisible];
[window addSubview:rootViewController.view];
return YES;

我的RootViewController：

My RootViewController:

- (void)viewDidLoad {
[super viewDidLoad];
adBannerView = [[ADBannerView alloc] initWithFrame:CGRectZero()];
[self.view addSubview:adBannerView];

}

我尝试过实验按钮而不是adBanner，我得到相同的结果。

I've tried instanciating buttons instead of the adBanner and I get the same result.

我的RootViewController的nib没有被更改，因为x-code为我创建了它。
我的MainWindow_iPhone.xib也是股票。

My RootViewController's nib has not been changed since x-code created it for me. My MainWindow_iPhone.xib also is stock.

造成这种情况的原因是什么？

What's causing this?

更新

更改应用程序的方向后，adBannerView（或按钮...）将在y = 0处捕捉到正确的位置。我已经尝试将adBannerView的y位置设置为20，可能是为了补偿状态栏，这使得所有内容都能正确显示，直到我改变方向。然后一切都向下移动20个像素，并在adBannerView和状态栏之间留出20个像素的空间。

After changing the app's orientation the adBannerView (or button...) will snap into the correct place at y=0. I've tried setting adBannerView's y location to 20 presumably to compensate for the status bar and that makes everything display correctly until I change orientation. Then everything moves down 20 pixels and will leave a 20 pixel space between the adBannerView and the status bar.

推荐答案

尝试添加 viewDidLoad 中的下一行（在 [super viewDidLoad]; 之后）：

Try to add the next line in your viewDidLoad (right after [super viewDidLoad];):

self.view.frame = [[UIScreen mainScreen] applicationFrame];
