Status bar and navigation bar appear over my view's bounds in iOS 7

You can achieve this by implementing a new property called edgesForExtendedLayout in iOS7 SDK. Please add the following code to achieve this,

if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
        self.edgesForExtendedLayout = UIRectEdgeNone;

You need to add the above in your -(void)viewDidLoad method.

iOS 7 brings several changes to how you layout and customize the appearance of your UI. The changes in view-controller layout, tint color, and font affect all the UIKit objects in your app. In addition, enhancements to gesture recognizer APIs give you finer grained control over gesture interactions.

Using View Controllers

In iOS 7, view controllers use full-screen layout. At the same time, iOS 7 gives you more granular control over the way a view controller lays out its views. In particular, the concept of full-screen layout has been refined to let a view controller specify the layout of each edge of its view.

The wantsFullScreenLayout view controller property is deprecated in iOS 7. If you currently specify wantsFullScreenLayout = NO, the view controller may display its content at an unexpected screen location when it runs in iOS 7.

To adjust how a view controller lays out its views, UIViewController provides the following properties:

• edgesForExtendedLayout

The edgesForExtendedLayout property uses the UIRectEdge type, which specifies each of a rectangle’s four edges, in addition to specifying none and all. Use edgesForExtendedLayout to specify which edges of a view should be extended, regardless of bar translucency. By default, the value of this property is UIRectEdgeAll.

• extendedLayoutIncludesOpaqueBars

If your design uses opaque bars, refine edgesForExtendedLayout by also setting the extendedLayoutIncludesOpaqueBars property to NO. (The default value of extendedLayoutIncludesOpaqueBars is NO.)

• automaticallyAdjustsScrollViewInsets

If you don’t want a scroll view’s content insets to be automatically adjusted, set automaticallyAdjustsScrollViewInsets to NO. (The default value of automaticallyAdjustsScrollViewInsets is YES.)

• topLayoutGuide, bottomLayoutGuide

The topLayoutGuide and bottomLayoutGuide properties indicate the location of the top or bottom bar edges in a view controller’s view. If bars should overlap the top or bottom of a view, you can use Interface Builder to position the view relative to the bar by creating constraints to the bottom of topLayoutGuide or to the top of bottomLayoutGuide. (If no bars should overlap the view, the bottom of topLayoutGuide is the same as the top of the view and the top of bottomLayoutGuide is the same as the bottom of the view.) Both properties are lazily created when requested.

You don‘t have to calculate how far to shift everything down, there‘s a build in property for this. In Interface Builder, highlight your view controller, and then navigate to the attributes inspector. Here you‘ll see some check boxes next to the words "Extend Edges". As you can see, in the first screenshot, the default selection is for content to appear under top and bottom bars, but not under opaque bars, which is why setting the bar style to not translucent worked for you.

As you can somewhat see in the first screenshot, there are two UI elements hiding below the navigation bar. (I‘ve enabled wireframes in IB to illustrate this) These elements, a UIButton and a UISegmentedControl both have their "y" origin set to zero, and the view controller is set to allow content below the top bar.

This second screenshot shows what happens when you deselect the "Under Top Bars" check box. As you can see, the view controllers view has been shifted down appropriately for its y origin to be right underneath the navigation bar.

This can also be accomplished programmatically through the usage of -[UIViewController edgesForExtendedLayout]. Here‘s a link to the class reference for edgeForExtendedLayout, and forUIRectEdge

[self setEdgesForExtendedLayout:UIRectEdgeNone];

I created my view programmatically and this ended up working for me:

- (void) viewDidLayoutSubviews {
    // only works for iOS 7+
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect viewBounds = self.view.bounds;
        CGFloat topBarOffset = self.topLayoutGuide.length;

        // snaps the view under the status bar (iOS 6 style)
        viewBounds.origin.y = topBarOffset * -1;

        // shrink the bounds of your view to compensate for the offset
        viewBounds.size.height = viewBounds.size.height + (topBarOffset * -1);
        self.view.bounds = viewBounds;
    }
}

If you want the view to have the translucent nav bar (which is kind of nice) you have to setup a contentInset or similar.

Here is how I do it:

// Check if we are running on ios7
if([[[[UIDevice currentDevice] systemVersion] componentsSeparatedByString:@"."][0] intValue] >= 7) {
      CGRect statusBarViewRect = [[UIApplication sharedApplication] statusBarFrame];
      float heightPadding = statusBarViewRect.size.height+self.navigationController.navigationBar.frame.size.height;

      myContentView.contentInset = UIEdgeInsetsMake(heightPadding, 0.0, 0.0, 0.0);
}

edgesForExtendedLayout does the trick for iOS 7. However, if you build the app across iOS 7 SDK and deploy it in iOS 6, the navigation bar appears translucent and the views go beneath it. So, to fix it for both iOS 7 as well as for iOS 6 do this:

self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
    self.edgesForExtendedLayout = UIRectEdgeNone;   // iOS 7 specific

In your apps plist file add a row, call it "View controller-based status bar appearance" and set it to NO.

The simplest trick is to open the NIB file and do these two simple steps:

1. Just toggle that and set it to the one you prefer:

1. Select those UIView‘s/UIIMageView‘s/... that you want to be moved down. In my case only the logo was overlapped an I‘ve set the delta to +15; (OR -15 if you chose iOS 7 in step 1)

And the result:

I would like to expand on Stunner‘s answer, and add an if statement to check if it is iOS-7, because when I tested it on iOS 6 my app would crash.

The addition would be adding:

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)

So I would suggest adding this method to your MyViewControler.m file:

- (void) viewDidLayoutSubviews {
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect viewBounds = self.view.bounds;
        CGFloat topBarOffset = self.topLayoutGuide.length;
        viewBounds.origin.y = topBarOffset * -1;
        self.view.bounds = viewBounds;
    }
}

I have a scenario where I use the BannerViewController written by Apple to display my ads and a ScrollViewController embedded in the BannerViewController.

To prevent the navigation bar from hiding my content, I had to make two changes.

1) Modify BannerViewController.m

- (void)viewDidLoad
{
   [super viewDidLoad];
   float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
   if (systemVersion >= 7.0) {
      self.edgesForExtendedLayout = UIRectEdgeNone;
   }
}

2) Modify my ScrollViewContoller

- (void)viewDidLoad
{
    [super viewDidLoad];
    float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (systemVersion >= 7.0) {
        self.edgesForExtendedLayout = UIRectEdgeBottom;
    }
}

Now the ads show up correctly at the bottom of the view instead of being covered by the Navigation bar and the content on the top is not cut off.

To me, the simplest solution is to add two keys into the plist

Add the key "View Controller-based status bar appearance" from the dropdownlist as a row in info.plist. Something like this:

Steps For Hide the status bar in iOS 7:

1.Go to your application info.plist file.

2.And Set, View controller-based status bar appearance : Boolean NO

Hope i solved the status bar issue.....
