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 have a page view controller embedded inside a container view in order to swipe between images. But now I am trying to add a touch that will make the image go full screen "lightbox" with zoom available and also swipe through the images while in full screen mode.
I can get it to work, and messing around with auto layout seems to be much work consider I have a lot of other stuff in that VC.
So does anyone know a good image slider from github written in swift? - without the need of cocopods.
thanks!
It's easy enough to write one yourself. In full-screen mode, use another UIPageViewController, because it already has the swipe left & right support built in.
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 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.
I have question regarding changing orientation on iPad.
I use MonoTouch, but if Obj-C programmers can help, it will be just as great.
First of all, I figured out if I provide different splash screen images for different orientations, app will show the right one. This can be done for any orientation, such as "Default-LandscapeLeft.png", or generic one "Default-Landscape.png".
All of my images are of correct dimensions and yet, when I start it in portrait mode, it shows it enlarged. All of other modes work perfectly well.
Second problem is I want my app to continue to be in that orientation after my first controller appear. At the moment, it shows portrait in any case. I started generating orientation notifications before first controller appeared (UINavigationController), but I think it responds only on orientation changes. After I moved device, it rotates and from that moment, everything works fine. BUT, I want to "inherit" orientation info from my splash screen.
Any idea will be appreciated.
Thanks guys and girls.
Cheers
Images for different orientations:
Default.png and Default-Landscape.png should be provided + setting the app settings to provide the required orientations.
Second problem:
After creating the first controller call
myController.WillRotate(UIApplication.SharedApplication.StatusBarOrientation, 0);
I have a application that I am working on that is in landscape mode and does not rotate. However I can not get the text field to rotate. I have been putting in way to many hours so don't be to harsh if this is a easy answer...
Are you using Interface Builder to create the view? In that case, adding the UITextField to the UIView in landscape mode. In case you do not know how to use IB for creating views in landscape mode, open the UIView object in IB. There is a small arrow on the top-right corner of the view. Click on that arrow to rotate the view to landscape mode.
Edit your Info.plist file so that it includes the "Initial device orientation" key and specify UIDeviceOrientationLandscapeLeft (the Home button should be to the right if an app opens in landscape, according to Apple's UI guidelines). Some samples come with this property already in the plist, but most don't.
