Status bar and navigation bar issue in IOS7

Question

I am migrating my application to iOS 7. For handing the status bar issue I have added this code

if([[[UIDevice currentDevice] systemVersion] floatValue] >         


        

Answer 1

Hear we can do this for all views at once

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{
// Notification for the orientaiton change
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(applicationDidChangeStatusBarOrientation:)
                                             name:UIApplicationDidChangeStatusBarOrientationNotification
                                           object:nil];

// Window framing changes condition for iOS7 or greater
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    statusBarBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, -20, self.window.frame.size.width, 20)];//statusBarBackgroundView is normal uiview
    statusBarBackgroundView.backgroundColor = [UIColor colorWithWhite:0.000 alpha:0.730];
    [self.window addSubview:statusBarBackgroundView];
    self.window.bounds = CGRectMake(0, -20, self.window.frame.size.width, self.window.frame.size.height);
}
// Window framing changes condition for iOS7 or greater

self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];


return YES;
}

And While we are using orientation we can add below method in app delegate to set it via orientation.

- (void)applicationDidChangeStatusBarOrientation:(NSNotification *)notification
{
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    statusBarBackgroundView.hidden = YES;
    UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
    int width = [[UIScreen mainScreen] bounds].size.width;
    int height = [[UIScreen mainScreen] bounds].size.height;

    switch (orientation) {
        case UIInterfaceOrientationLandscapeLeft:
            self.window.bounds =  CGRectMake(-20,0,width,height);
            statusBarBackgroundView.frame = CGRectMake(-20, 0, 20, height);
            break;
        case UIInterfaceOrientationLandscapeRight:
            self.window.bounds =  CGRectMake(20,0,width,height);
            statusBarBackgroundView.frame = CGRectMake(320, 0, 20, height);
            break;
        case UIInterfaceOrientationPortraitUpsideDown:
            statusBarBackgroundView.frame = CGRectMake(0, 568, width, 20);
            self.window.bounds =  CGRectMake(0, 20, width, height);
            break;
        default:
            statusBarBackgroundView.frame = CGRectMake(0, -20, width, 20);
            self.window.bounds =  CGRectMake(0, -20, width, height);
            break;
    }
    statusBarBackgroundView.hidden = NO;
}
}

You should Add below navigation controller category for it

.h

#import 
#import 
@interface UINavigationController (iOS6fix)

@end

.m

#import "UINavigationController+iOS6fix.h"
@implementation UINavigationController (iOS6fix)  

-(BOOL)shouldAutorotate
{
      return [[self.viewControllers lastObject] shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
      return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
     return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}

@end
