iOS 隱藏狀態欄

當系統版本號高於iOS7.0,那麼原來的隱藏狀態欄方式就可能不好使了. 因為你要是用修改plist的方法實現的隱藏方法,還是管用的.

 1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 2     // Override point for customization after application launch.
 3     if ([UIDevice currentDevice].systemVersion.floatValue < 7.0) {
 4         [UIApplication sharedApplication].statusBarHidden = YES;
 5     }
 6     else if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)])
 7     {
 8         // iOS7及以上
 9         [self prefersStatusBarHidden];
10         //這個是更新狀態欄的顯示狀態,只支持iOS7及以上,使用performSelector是為了不影響主線程的其他工作
11         [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
12     }
13     return YES;
14 }
15 
16 - (BOOL)prefersStatusBarHidden
17 {
18     return YES;//隱藏為YES，顯示為NO
19 }
