iphone - Navigation bar appear over the views with new iOS7 SDK

Question

CGRect cgRect1 = [[UIScreen mainScreen] applicationFrame];


UISearchBar  *mySearchBar = [[UISearchBar alloc] 
               initWithFrame:CGRectMake(0, 0, cgRect.size.width, 40)];

mySearchBar.autoresizingMask = 
              UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight ;


UITableView  *myTableView = [[UITableView alloc] 
     initWithFrame:CGRectMake(0, 40, cgRect.size.width, cgRect.size.height-40)];

myTableView.autoresizingMask = 
               UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;


[self.view addSubview:mySearchBar];
[self.view addSubview:myTableView];

In the earlier versions it is working correctly. The search bar is appearing below the statusbar and navigation bar. The tableview is appearing below the search bar

But when I run this on Xcode 5 sdk iOS 7, the search bar is not visible (I think its placed under the status bar and navigation bar) , and also the navigation bar is appearing over the table view.

Will it be fixed with iOS 7 stable release ?

Or is it the problem of my coding ?

Or should we handle it by adding the y (y = statubar height + nav bar height) value for iOS 7 ?

I recently downloaded Xcode 5 DP to test my apps in iOS 7. The first thing I noticed and confirmed is that my view's bounds is not always resized to account for the status bar and navigation bar.

In viewDidLayoutSubviews, I print the view's bounds:

{{0, 0}, {320, 568}}

This results in my content appearing below the navigation bar and status bar.

I know I could account for the height myself by getting the main screen's height, subtracting the status bar's height and navigation bar's height, but that seems like unnecessary extra work.

Has anyone else experienced this issue?

UPDATE:

I've found a solution for this specific problem. Set the navigation bar's translucent property to NO:

self.navigationController.navigationBar.translucent = NO;

This will fix the view from being framed underneath the navigation bar and status bar.

However, I have not found a fix for the case when you want the navigation bar to be translucent. For instance, viewing a photo full screen, I wish to have the navigation bar translucent, and the view to be framed underneath it. That works, but when I toggle showing/hiding the navigation bar, I've experienced even stranger results. The first subview (a UIScrollView) gets its bounds y origin changed every time.

Answer 1

That’s not entirely true. There has been a new property introduced in iOS 7 that lets you adjust the layout behavior as in previous versions of iOS. Place this piece of code in your view controller, and you should be good to go! The space your navigation bar takes up should be accounted for automatically

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

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

Note: You should be using the latest GM release of iOS 7 and Xcode 5 now since the API has changed from beta versions.
