UINavigationBar出现在UIStatusBar下面

Question

UINavigationBar出现在UIStatusBar in iOS 6下(它在iOS 7中运行正常)，我使用的是Xocde 5的故事板。

​

这是我的代码片段

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [UIApplication sharedApplication].statusBarHidden = NO;

    if ([[[UIDevice currentDevice] systemVersion] floatValue] < 7) //iOS 6
    {
        [[UITabBar appearance] setBackgroundImage:[UIImage imageNamed:@"TabImg.png"]];
        [[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:.7 green:.2 blue:.1 alpha:1.0]];
        [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
    }

    return YES;
}

HomePage上的代码，

- (void)viewDidLoad
{
    [super viewDidLoad];

        CRViewController *Obj=[[CRViewController alloc] init];
        [self.tabBarController presentViewController:Obj animated:YES completion:nil];

}

当我在didFinishLaunchingWithOptions方法之后运行我的应用程序时，viewDidLoad被解雇了，这就调用了CRViewController类。

CRViewController上的代码，

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self.navigationController setNavigationBarHidden:YES];
    self.tabBarController.tabBar.hidden = YES;
    [UIApplication sharedApplication].statusBarHidden = YES;

     ...
     ...
     ...

}



- (IBAction)SkipClick:(id)sender {
    [self dismissViewControllerAnimated:YES completion:nil];
}

-(void)viewDidDisappear:(BOOL)animated{
    [self.navigationController setNavigationBarHidden:NO];
    self.tabBarController.tabBar.hidden = NO;
    [UIApplication sharedApplication].statusBarHidden = NO;
}

，我在哪里做错了??

预先谢谢.

Navigation is showing in ios 7 than you have check this it will work


NSString *version = [[UIDevice currentDevice] systemVersion];
int ver = [version intValue];
if (ver > 7)
{
}
else
{
    self.edgesForExtendedLayout = UIRectEdgeNone;

}

self.tabBarController.tabBar.hidden = YES；在ios 7中不工作，它显示的是黑色屏幕。比你能隐藏的还要多

-(void)hideTabBar

{

UITabBar *tabBar = self.tabBarController.tabBar；

UIView *parent = tabBar.superview；// UILayoutContainerView

UIView *content = parent.subviews objectAtIndex:0；// UITransitionView

UIView *window = parent.superview；

[UIView动画:0.5

动画：^{

CGRect tabFrame = tabBar.frame；

TabFrame.原.y= CGRectGetMaxY(window.bounds)；

tabBar.frame = tabFrame；content.frame = window.bounds；

}]；

}
