I'm adapting my app to iphone 5 and I've got a problem. I saw all documentation regarding this and it didn't work yet.
I put the Default-568h#2x.png and everything resized successfully.
The problem is in the touch stuff. I've got a toolbar on the bottom and when I touch it nothing happens :( in the retina 4" simulator. Works fine in retina 3.5
In retina 4", if I set the toolbar in the inspector above 439 px in the Y position works fine. Anything below this makes my toolbar not to work.
As I said, I tried many many things unsuccessfully.
I'm using Xcode 4.6.1, I've got a Main View (not having a Window option in the Attributes inspector).
Thanks in advance.
Your window or the main view is not resizing correctly. Make sure you have set them up such that they autoresize in both directions. Try to set different background colors to your views to find the view that is not resizing correctly.
Ensure that all of your views are auto-resizing correctly to fill the screen. It sounds like the main container view you have isn't being resized and is drawing the toolbar outside of its frame. This will work from a visual point of view as UIView - clipsToBounds defaults to NO, but touches won't work outside the frame.

This might be a silly question, but why in the world can't I see the the following button that I simply dragged and dropped to the view from the interface builder?
I am using Simulator iPhone Retina (3.5 inch) / iOS 7. When I try to scroll to the bottom, the scrolling ends and I cannot see the button that I placed at the bottom. Why is that? Thanks.
EDIT: I didn't do anything fancy. I simply created a new single view app, and then dragged the button to the bottom of the view on storyboard and then clicked run.
Storyboard simulate size of 4 inch display. When you run it on 3.5 inch display, content at the bottom of the screen will be clipped.
Just add constraints to attach button to bottom of the screen.
I am in the process of transitioning an app to iOS7. All of the views throughout the app have a 44px empty space at the bottom that appears to be for a bottom toolbar or something, but I am not trying to display a bottom toolbar. This space also exists on views that do have a bottom toolbar and the toolbar just shows directly above it.
The red space shown is actually a view behind the black view. No matter what size I set the frame of the black view to, the red space is always shown. I am also hiding the status bar in plist, so don't know if this is an artifact from that or if it has something to do with navigation bar as they are both normally 44px in height.
I have looked at the transitioning guide and haven't found anything that's worked. Any ideas to what could be causing this and how to fix?
UPDATE:
I have tried setting edgesForExtendedLayout = UIRectEdgeAll and extendedLayoutIncludesOpaqueBars = YES (also tried NO) with no effect. When I look at the subviews of the navigation controller it shows a UIToolBar as hidden, but shows it contains a frame in the exact area the view refuses to resize to even with autolayout constraints.
UPDATE 2:
This is actually a problem with ViewDeckController (https://github.com/Inferis/ViewDeck) and the way it sets it's center view bounds.
I believe it has to do with the UINavigationBar. Try toggling the following options in Storyboard and see if it solves the problem. Namely, the 'Extend Edges' options:
These options can also be set in code with the edgesForExtendedLayout and extendedLayoutIncludesOpaqueBars properties on UIViewController.
If you are transitioning to iOS 7, you should be using an Auto Layout constraint to anchor to the Bottom Layout guide. Control drag from your view to the Bottom Layout guide and choose Vertical Space from the popup menu.
Using frames in iOS 7 is harder and is the way of the past.
Auto Layout is hard to grasp at first, but it is very powerful once you get the feel.
This is actually a problem with third party library ViewDeckController (https://github.com/Inferis/ViewDeck) and the way it sets centerViewBounds for IIViewDeckControllerIntegrated. I was able to figure it out after changing to IIViewDeckControllerContained and seeing the view sized correctly.
In IIViewDeckController.m, just return self.referenceBounds for iOS7 like it does for IIViewDeckControllerContained.
I'm making an iPad application with 19 buttons which are alle graphics. They are aligned next to and underneath eatchother, like in a grid. In portrait mode they are displayed nicely (because that's how I've set them) but I don't know what settings I need to choose for landscape mode.
When the device turns to landscape I've got room for 4 columns in stead of 3 in portrait for instance.
How can I make the app automatically adjust they layout of the buttons when rotated?
Thanks
In iOS5.1 or older, you will need to do this in code. In iOS6, its possible you can use a UICollectionView - not sure haven't played with it.
I'm trying to make and iOS app with both portrait and landscape views, but if I open it and change the orientation to Landscape, some buttons got offscreen, after going to IB and reordering the buttons, in Portrait they go off screen.
After googling, I dont have ANY ideia how to 'change' views according to orientation.
Could you guys give me some help?
Ah, also, Apple Support Documents seems pretty useless to me :P
Thanks!
There a method - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{}
which is useful in such cases.
You should change autosizing properties in IB (they're in the same place where frame size is) or change autoresizingMask properties of your inner views and controls programmatically. This controls what happens to the elements of your screen after it gets resized (for example when the screen is rotating). You can glue your components to left or right or both, top or bottom or both and similar. Play with it, it's pretty powerful and you don't need any code for that if what they can do is enough.
I appreciate I'm probably missing something basic here, but...
My iPad app will only support landscape mode, and has a MainWindow.xib Window that I'd like to work on in landscape mode in XCode 4, however the pull-down menu to change this (Simulated Metrics -> Orientation) is always grayed out.
I notice that Views can be rotated just fine, it's only Windows that can't be rotated in XCode 4 using this setting.
Is there a workaround for this, or do I have to put a View on top of the MainWindow in order to rotate it?
I think it's because apps always starts up in portrait and then rotates to appropriate oriantations. From the UIViewController docs:
Note: At launch time, applications should always set up their
interface in a portrait orientation. After the
application:didFinishLaunchingWithOptions: method returns, the
application uses the view controller rotation mechanism described
above to rotate the views to the appropriate orientation prior to
showing the window.
So you'll need the UIViewController magic for the simulated metrics to make any sense. If you used the "Window-based application" template as a starting point for your project try the "View-based application" template instead.
