blocks|key|273822|text|但是，如果使用UIImagePicker，状态栏将再次出现。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|273823|在这种情况下，您应该隐藏状态栏，如下所示：|273824|-+(void)imagePickerController:(UIImagePickerController+*)aPicker+didFinishPickingMediaWithInfo:(NSDictionary+*)info+{

However, if you use UIImagePicker, the status bar appears again.

In that case, you should hide the status bar as below,

<pre><code>- (void)imagePickerController:(UIImagePickerController *)aPicker didFinishPickingMediaWithInfo:(NSDictionary *)info {

 [[UIApplication sharedApplication] setStatusBarHidden:YES];

After some long searching, I finally found a very simple solution which also takes care of the <code>UIImagePickerController</code> problem.

As mentioned in the other answers, set your status bar hidden in your AppDelegate didFinishLaunching, and set the "View controller-based status bar appearance" to NO.

Then, in your AppDelegate:

<pre><code>- (void)application:(UIApplication *)application didChangeStatusBarFrame:(CGRect)oldStatusBarFrame
{
 [application setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}
</code></pre>

et voila - your Status Bar will remain hidden even when the UIImagePickerController is foremost.

This is better than 'rehiding' it every time you present a UIImagePickerController as it remains hidden throughout the app.

I found this solution for me. It works like a charm.
Write this code on your viewcontroller which you wanted to use UIImagePickerController on.

<pre><code>- (void)viewWillDisappear:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}
- (void)viewWillAppear:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
 }
</code></pre>

blocks|key|57343|text|除了上面的答案之外，还要确保实现imagePickerControllerDidCancel方法，并在其中添加相同的代码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|57344|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In addition to the answer from alones above, make sure to implement the imagePickerControllerDidCancel method and add the same code there too.

blocks|key|273942|text|我对UIImagePicker也有一些问题。类似于Alones的回答，我的解决方案如下。我添加了以下行或代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|273943|[[UIApplication+sharedApplication]+setStatusBarHidden:YES];|code-block|syntax|javascript|273944|添加到此函数：|273945|-+(void)navigationController:(UINavigationController+*)navigationController+willShowViewController:(UIViewController+*)viewController+animated:(BOOL)animated|273946|我没有在iOS+6或更早的版本上测试过这一点，但它在iOS+7上运行得很好。|273947|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I was having issues with UIImagePicker as well. Similar to Alones answer, my solution was the following. I added this line or code:

<pre><code>[[UIApplication sharedApplication] setStatusBarHidden:YES];
</code></pre>

to this function:

<pre><code>- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
</code></pre>

I haven't tested this with iOS 6 or older but it works great in iOS 7.

blocks|key|57595|text|我使用的是Xcode6，这个解决方案适用于我的iOS+7和8：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|57596|首先，在plist文件中将“查看基于控制器的状态栏外观”设置为NO。|57597|其次，在AppDelegate中添加以下内容：|57598|-+(void)application:(UIApplication+*)application+didChangeStatusBarFrame:(CGRect)oldStatusBarFrame

I am using Xcode 6, this solution works on iOS 7 and 8 for me:

First, Set the "View controller-based status bar appearance" to NO in plist file.

Second, in AppDelegate, add this:

<pre><code>- (void)application:(UIApplication *)application didChangeStatusBarFrame:(CGRect)oldStatusBarFrame
{
 [application setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}
</code></pre>

blocks|key|274188|text|我的问题是我使用了视图控制器容器。例如，只有嵌入到导航控制器中的最顶部的视图控制器才能隐藏或显示状态栏。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|274189|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

My problem was that I used view controller containment. Only the top most view controller, which is embedded into a navigation controller for example, can hide or show the status bar.

I'm creating an application and I want the status bar hidden. When I test the app, the status bar is hidden whilst the splash screen is shown, but once the app is fully loaded, the status bar reappears.

I'm using Xcode 5 and iOS 7, and have tried disabling the status bar programatically

<pre><code> ([[UIApplication sharedApplication] setStatusBarHidden:YES 
 withAnimation:UIStatusBarAnimationFade];),
</code></pre>

in the info.plist file, and using the attributes inspector on the .xib file. Nothing appears to work. 

Any ideas?

Status bar won't disappear

我正在创建一个应用程序，并且我希望隐藏状态栏。当我测试应用程序时，状态栏隐藏，而闪屏显示，但一旦应用程序完全加载，状态栏重新出现。我正在使用Xcode5和iOS 7，并尝试以编程方式禁用状态栏  ([[UIApplication sharedApplication] setStatusBarHidden:YES          withAnimation:UIStatusBarAnimation
