Status bar and navigation bar issue in IOS7

Fix for status bar issue in IOS 7

Finally I fixed the status bar over lap issue using the delta value property in xcode5. First I have increased origin - y 20pxl to all the controller used in the Xib (it seams to be working fine only in IOS 7), after that I set the delta value for all the view controller origin -y to -20 it works fine in both iOS 6 and iOS 7.

Steps to do that.

Xcode 5 provide preview option to view the appearance of the xib in different view based on the OS version.

Choose preview option from assistant editor

Click assistant editor

and choose preview option to preview selected view controller in different version.

view controller view preview option.

in preview you can find the toggle option to preview view in different version. In preview u can feel the status bar issue clearly if its not fixed properly by toggle the version.

Three steps to fix the status bar issue:step 1: Make sure the view target us 7.0 and later in File inspector.

Step 2 : Increase the origin - y with 20 pixel (exactly the size of the status bar) for all the controls added in the view controller.

Step 3 : Set the delta value of origin y to -20 for all the controls then only it will adjust automatically based on the version. Use preview now and feel the differ that the controls automatically adjust because of the delta value.

Once the status bar issue fixed, issue while presenting the model view (ZbarSDk controller) is also fixed automatically.

I am late for this Answer, but i just want to share what i did, which is basically
the easiest solution

First of all-> Go to your info.plist File and add Status Bar Style->Transparent Black Style(Alpha of 0.5)

Now ,here it Goes:-

Add this code in your AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions    {     //Whatever your code goes here  if(kDeviceiPad){     //adding status bar for IOS7 ipad         if (IS_IOS7) {              UIView *addStatusBar = [[UIView alloc] init];              addStatusBar.frame = CGRectMake(0, 0, 1024, 20);              addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //change this to match your navigation bar              [self.window.rootViewController.view addSubview:addStatusBar];                    }                }    else{         //adding status bar for IOS7 iphone        if (IS_IOS7) {            UIView *addStatusBar = [[UIView alloc] init];            addStatusBar.frame = CGRectMake(0, 0, 320, 20);            addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //You can give your own color pattern            [self.window.rootViewController.view addSubview:addStatusBar];        }    return YES;   }

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];    // Override point for customization after application launch.    self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];    self.window.rootViewController = self.viewController; if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {        [application setStatusBarStyle:UIStatusBarStyleLightContent];         [application setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];        self.window.clipsToBounds =YES;                    self.window.frame =CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height-20);    }   [self.window makeKeyAndVisible];    return YES;}

set the following to info.plist

View controller-based status bar appearance = NO;
