Navigation bar and Status bar issue in iOS 7

问题

I have created an application using XIB without Status Bar before for iOS7, now i need to add Status bar on my app and Status bar background color should same as Navigation bar background color. So i have tried like (In my info.plist) :

1) Set View controller-based status bar appearance to NO
2) Set Status bar style to UIStatusBarStyleLightContent

here is my code for App Delegate:

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];

[[UINavigationBar appearance] setBarStyle:UIBarStyleDefault];
[[UINavigationBar appearance] setBackgroundColor:[UIColor colorWithRed:(51/255.0) green:(51/255.0) blue:(51/255.0) alpha:1.0]];
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:(51/255.0) green:(51/255.0) blue:(51/255.0) alpha:1.0]];

So i am getting the output like the below image :

also i am getting misplacement of UIButtons that i have given below in my screen (It's hiding 20 pixels).

Can you please help me that how can i fix this issue? I need my output like the below image :

Any help will be very appreciated, Thanks.

Add following code in your viewDidLoad method :

float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];

if (systemVersion >= 7.0) 
{
    self.edgesForExtendedLayout = UIRectEdgeNone;
}

回答2:

Please define this in AppDelegate.h (or) constants.h

  #define isIOS7  ([[[UIDevice currentDevice]systemVersion]floatValue] >=7.0)?YES:NO

under viewDidLoad Write this lines.

  if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
   UIView *addStatusBar = [[UIView alloc] init];
   addStatusBar.frame = CGRectMake(0, 0, 320, 20);
    addStatusBar.backgroundColor = [UIColor colorWithRed:0.973 green:0.973 blue:0.973 alpha:1];


     //change this to match your navigation bar
    [self.window.rootViewController.view addSubview:addStatusBar];
  }

OR we can change it manually in the xib.

By moving each element 20px down.

Surprise at how few people have suggested this. Here is the correct way (no hacking)

First, make your navigationBar have a Y origin of 20.

Then in the .h file, set your ViewController as a UIBarPositioningDelegate:

@interface XYZViewController : UIViewController <UIBarPositioningDelegate>

And in the .m file:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.navigationBar.delegate = self;
}

- (UIBarPosition)positionForBar:(id<UIBarPositioning>)bar { 
    return UIBarPositionTopAttached; 
}
