iPhone视图和状态栏

发布于 2024-10-22 04:25:46 字数 126 浏览 3 评论 0原文

当我将一个视图（view1）添加到另一个视图（view2）时，我发现一个错误：如果状态栏没有隐藏，添加视图（view1）后，下面的view1会出现20像素高的空栏。如果状态栏被隐藏，这种现象就会消失。谁能帮我解决这个问题。想你了！

只需检查状态栏是否隐藏并通过添加 20 个像素来调整第二个 UIView 的框架

if([[UIApplication sharedApplication] isStatusBarHidden])
        view2.frame = CGRect(x,y,width,height);
    else
        view2.frame = CGRect(x,y+20,width,height);

Just check if the statusbar is hidden and adjust the frame of your second UIView by adding 20 pixels

if([[UIApplication sharedApplication] isStatusBarHidden])
        view2.frame = CGRect(x,y,width,height);
    else
        view2.frame = CGRect(x,y+20,width,height);

作为一个更具体的示例，我有一个情况，在应用程序启动后，我实际上还没有准备好让用户看到屏幕上发生的情况。在这种情况下，我有一个仍在渲染的 Web 视图，因此我将 Default.png 文件覆盖到我的视图上，而后台发生了一些垃圾。

// put the default image over the whole screen while we wait for the html to load
UIImageView * defaultImageView = [[UIImageView alloc] initWithImage: [UIImage imageNamed:@"Default.png"]] ;
[self.view addSubview:defaultImageView];  


// adjust for status bar
if(![[UIApplication sharedApplication] isStatusBarHidden]) {//http://stackoverflow.com/questions/5310975/iphone-view-and-statusbar
    CGRect imageRect = defaultImageView.frame;
    imageRect.origin.y = imageRect.origin.y - 20;
    defaultImageView.frame = imageRect;
  }

Now, later in the code, remove the subview....

As a more concrete example, I have a case where, after the application has launched, I'm actually not quite ready for the user to see what is happening on the screen. In this case, I have a webview that is still rendering, so I overlay the the Default.png file onto my view while some junk happens in the background.

// put the default image over the whole screen while we wait for the html to load
UIImageView * defaultImageView = [[UIImageView alloc] initWithImage: [UIImage imageNamed:@"Default.png"]] ;
[self.view addSubview:defaultImageView];  


// adjust for status bar
if(![[UIApplication sharedApplication] isStatusBarHidden]) {//http://stackoverflow.com/questions/5310975/iphone-view-and-statusbar
    CGRect imageRect = defaultImageView.frame;
    imageRect.origin.y = imageRect.origin.y - 20;
    defaultImageView.frame = imageRect;
  }

Now, later in the code, remove the subview....
