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.

Solution 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.

Solution 2

If you are working in Storyboard (which I strongly recommend!) this is the solution: You can disable "Extend Edges" of your ViewController in storyboard. You have to do this for each viewController. You can disable extended edges by clicking the viewController icon in stortyboard (besides the productOwner beneath the view itself) and then selecting the attributes inspector (Like the images shows).

This will also set the alignment lines like iOS 6.

Another great tool in xCode 5 is "Preview": click on the butler Button (assistant editor) and select Preview. there you can select iOS 6 and see how your storyboard design will look like on iOS 6.

Its just great:D

[Update]

Be careful: disabling "Extend Edges" might result in a black glow on the navigation bar when the app enters background on iOS7. the glow will also be visible on the multitasking view (double press on home button). this can be solved by setting the background color of the navigation's bar view to white.

[self.navigationController.view setBackgroundColor:[UIColor whiteColor]];

Solution 3

As the OP says, there is a simple solution to this which is to set the navigation bar to be opaque. Rather than doing this in code, simply untick "Translucent" for your root navigation bar:

Solution 4

self.edgesForExtendedLayout=UIRectEdgeNone;

It works on iOS 7 simulator(Xcode 5 DP5)

Solution 5

these answers were all helpful, especially MQoder's, but for me i also had to set the default top bar to "opaque black navigation".

Beta software. Apple developer forums are more appropiate. Also, the problem is explicitely mentioned in the transition guide.

[Admin]

in My code it says edgesForExtendedLayout. Use of undeclared identifier UIExtendedEdgeNone. Please help.

[Simon]

It's changed to UIRectEdgeNone

[Sulthan]

That's exactly the reason why such a question shouldn't be asked or answered here.

[jerrygdm]

I don't undestand why if you want to keep compatibility with ios6 you are forced to introduce a conditional case by code to check if the controller has that property or not..

[Sathe_Nagaraja]

if you don't check, u'll end up with an exception

[loganathan]

this works fine in ios7 but if i ran the app on ios 6 and earlier again the views are moved up. Any solution for this?. Also we need to set this property in each view controller viewdid load method?

[One Man Crew]

Read the question , it's for iOS iOS7

[pojo]

This only seems to work if the view's embedded in a UINavigationController.

[KarenAnne]

@pojo Does it only work if the app uses UINavigationController?

[KarenAnne]

Yah, I saw in this answer that edgesForExtendedLayout only works when it is a Container View Controller.

[Erhan Demirci]

it's working very well. because sometimes my object position is going onether position . when ı add to viewdidload , it's solved

[Aviel Gross]

you can always check if the current iOS is 7 with this if: if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1)

@OneManCrew yes its working fine for me. but my app have Tabbacontroller alos. Rest of the viewcontroller is working fine. Issue in Tabbar view controller. suppose i have 5 tab. 1. when i click on tab (List screen open) it working fine when i click on list detail open fine. up to yet its working fine 2. when i click on tab 2 (another list) open. that time when i clickon tab1 than detail screen main view frame decrease to 64px. i have tried to forcefully increase but not working .. what can i do in this case ??

[jpittman]

Yep, this is the solution coming at it from a storyboard perspective. Thank you.

[piaChai]

What if the view is not embedded in a UINavigationController,and storyboard or xib etc are not used, then what is the solution?

[Johnus]

Does changing the title bar to not be translucent affect this behaviour?
