iOS 6 apps - how to deal with iPhone 5 screen size

Question

Possible Duplicate    How to develop or migrate apps for iPhone 5 screen resolution        I was just wondering with how should we deal with the iPhone 5 bigger screen size   As it has more pixels in height  things like GCRectMake that use coordinates  and just doubled the pixels with the retina non retina problem  won t work seamlessly between versions  as it happened when we got the Retina   And will we have to design two storyboards  just like for the iPad   I personally don t think Apple will require you to check the screen size every time you have to draw something  like many answers say  Does that happen with the iPad

Pascal s comment on the OP s question is right  By simply adding the image  it removes the black borders and the app will use the full height   You will need to make adjustments to any CGRects by determining that the device is using the bigger display  I e  If you need something aligned to the bottom of the screen   I am sure there is a built in method  but I haven t seen anything and a lot is still under NDA so the method we use in our apps is quite simply a global function  Add the following to your  pch file and then its a simple if  is4InchRetina             call to make adjustments to your CGRects etc   static BOOL is4InchRetina         if    UIApplication sharedApplication  statusBarHidden  amp  amp   int   UIScreen mainScreen  applicationFrame  size height    548     UIApplication sharedApplication  statusBarHidden  amp  amp   int   UIScreen mainScreen  applicationFrame  size height    568          return YES       return NO

I think you can use  UIScreen mainScreen  bounds size height and calculate step for your objects  when you calculate step you can set coordinates for two resolutions    Or you can get height like above and if iphone5  then    else if iphone4  then    else if ipad   Something like this   If you use storyboards then you have to create new for new iPhone i think

No   if    UIScreen mainScreen  bounds  size height  gt  960    on iPhone 5 is wrong  if    UIScreen mainScreen  bounds  size height    568

I have just finished updating and sending an iOS 6 0 version of one of my Apps to the store  This version is backwards compatible with iOS 5 0  thus I kept the shouldAutorotateToInterfaceOrientation  method and added the new ones as listed below   I had to do the following   Autorotation is changing in iOS 6  In iOS 6  the shouldAutorotateToInterfaceOrientation  method of UIViewController is deprecated  In its place  you should use the supportedInterfaceOrientationsForWindow  and shouldAutorotate methods   Thus  I added these new methods  and kept the old for iOS 5 compatibility    -  BOOL shouldAutorotate       return YES     -  NSUInteger supportedInterfaceOrientations       return UIInterfaceOrientationMaskAllButUpsideDown           Used the view controller   s viewWillLayoutSubviews method and adjust the layout using the view   s bounds rectangle   Modal view controllers  The willRotateToInterfaceOrientation duration   willAnimateRotationToInterfaceOrientation duration   and didRotateFromInterfaceOrientation  methods are no longer called on  any view controller that makes a full-screen presentation over itself   for example  presentViewController animated completion   Then I fixed the autolayout for views that needed it  Copied images from the simulator for startup view and views for the iTunes store into PhotoShop and exported them as png files  The name of the default image is  Default-568h 2x png and the size is 640 times 1136  It  s also allowed to supply 640 times 1096 for the same portrait mode  Statusbar removed   Similar sizes may also be supplied in landscape mode if your app only allows landscape orientation on the iPhone  I have dropped backward compatibility for iOS 4  The main reason for that is because support for armv6 code has been dropped  Thus  all devices that I am able to support now  running armv7  can be upgraded to iOS 5  I am also generation armv7s code to support the iPhone 5 and thus can not use any third party frameworks  as Admob etc   until they are updated    That was all but just remember to test the autorotation in iOS 5 and iOS 6 because of the changes in rotation

All apps will continue to work in the vertically stretched screen from what I could tell in today s presentation  They will be letterboxed or basically the extra 88 points in height would simply be black   If you only plan to support iOS 6   then definitely consider using Auto Layout  It removes all fixed layout handling and instead uses constraints to lay things out  Nothing will be hard-coded  and your life will become a lot simpler   However  if you have to support older iOS s  then it really depends on your application  A majority of applications that use a standard navigation bar  and or tab bar  could simply expand the content in the middle to use up that extra points  Set the autoresizing mask of the center content to expand in both directions   view autoresizingMask   UIViewAutoresizingFlexibleWidth   UIViewAutoresizingFlexibleHeight    It works great out of the box for table views  however  if your app used pixel-perfect layout for displaying content  then your best bet would be to re-imagine the content so that it can accommodate varying heights   If that s not a possibility  then the only remaining option is to have two UIs  pre iPhone 5  and iPhone 5    If that sounds ugly  then you could go with the default letterboxed model where the extra points pixels just show up black   Edit  To enable your apps to work with iPhone 5  you need to add a retina version of the launcher image  It should be named Default-568h 2x png  And it has to be retina quality - there s no backward compatibility here      You could also select this image from within Xcode  Go to the target  and under the Summary section  look for Launch Images  The image has to be 640x1136 pixels in size  Here s a screenshot of where to find it  if that helps

As it has more pixels in height  things like GCRectMake that use coordinates won t work seamlessly between versions  as it happened when we got the Retina    Well  they do work the same with Retina displays - it s just that 1 unit in the CoreGraphics coordinate system will correspond to 2 physical pixels  but you don t didn t have to do anything  the logic stayed the same   Have you actually tried to run one of your non-retina apps on a retina iPhone  ever    For the actual question  that s why you shouldn t use explicit CGRectMakes and co    That s why you have stuff like   UIScreen mainScreen  applicationFrame

You need to add a 640x1136 pixels PNG image  Default-568h 2x png  as a 4 inch default splash image of your project  and it will use extra spaces  without efforts on simple table based applications  games will require more efforts    I ve created a small UIDevice category in order to deal with all screen resolutions  You can get it here  but the code is as follows   File UIDevice Resolutions h   enum       UIDeviceResolution Unknown             0      UIDeviceResolution iPhoneStandard      1        iPhone 1 3 3GS Standard Display   320x480px      UIDeviceResolution iPhoneRetina4      2        iPhone 4 4S Retina Display 3 5    640x960px      UIDeviceResolution iPhoneRetina5       3        iPhone 5 Retina Display 4         640x1136px      UIDeviceResolution iPadStandard        4        iPad 1 2 mini Standard Display    1024x768px      UIDeviceResolution iPadRetina          5        iPad 3 Retina Display             2048x1536px     typedef NSUInteger UIDeviceResolution    interface UIDevice  Resolutions   -  UIDeviceResolution resolution   NSString  NSStringFromResolution UIDeviceResolution resolution     end   File UIDevice Resolutions m    import  UIDevice Resolutions h    implementation UIDevice  Resolutions   -  UIDeviceResolution resolution       UIDeviceResolution resolution   UIDeviceResolution Unknown      UIScreen  mainScreen    UIScreen mainScreen       CGFloat scale     mainScreen respondsToSelector  selector scale     mainScreen scale   1 0f       CGFloat pixelHeight    CGRectGetHeight mainScreen bounds    scale        if  UI USER INTERFACE IDIOM      UIUserInterfaceIdiomPhone           if  scale    2 0f                if  pixelHeight    960 0f                  resolution   UIDeviceResolution iPhoneRetina4              else if  pixelHeight    1136 0f                  resolution   UIDeviceResolution iPhoneRetina5             else if  scale    1 0f  amp  amp  pixelHeight    480 0f              resolution   UIDeviceResolution iPhoneStandard         else           if  scale    2 0f  amp  amp  pixelHeight    2048 0f                resolution   UIDeviceResolution iPadRetina             else if  scale    1 0f  amp  amp  pixelHeight    1024 0f                resolution   UIDeviceResolution iPadStandard                       return resolution        end   This is how you need to use this code   1  Add the above UIDevice Resolutions h  amp  UIDevice Resolutions m files to your project  2  Add the line  import  UIDevice Resolutions h  to your ViewController m  3  Add this code to check what versions of device you are dealing with  int valueDevice     UIDevice currentDevice  resolution        NSLog   valueDevice   d       valueDevice        if  valueDevice    0                  unknow device - you got me            else if  valueDevice    1                  standard iphone 3GS and lower           else if  valueDevice    2                  iphone 4  amp  4S           else if  valueDevice    3                  iphone 5           else if  valueDevice    4                  ipad 2           else if  valueDevice    5                  ipad 3 - retina display
