I am trying to do the following
UISplitViewController in portrait on iPhone shows detail VC instead of master
Open UISplitViewController to Master View rather than Detail
They all revolve around the delegate method collapseSecondary secondaryViewController:UIViewController, onto primaryViewController:UIViewController
I've been subclassing, moving classes, delegates etc for 4 hours now. This method won't get called. Hooked it up to an actual iPad in case it's a simulator problem. I now even ran the sample Master Detail project and it also doesn't call this method
What are you supposed to do to get this method triggered? When it won't even execute in the standard template project where you'd expect to have the delegate etc. set up correctly?
Steps to reproduce:
File > New > Project
Master-Detail App
In AppDelegate.swift search for collapseSecondary secondaryViewController
Make it end in ... -> Bool {
print("CALLED"); return true}
Wait 2 years for this to finally print because it won't.
Please help me I am so frustrated with this. Setting this up in Android took me 3 minutes but for iOS being so special and everything I probably need to request for a written permission to unlock this "feature" for me.
On the iPad, enter multi-tasking by dragging an app from the dock onto the right side, then drag the splitter line over to the left. Now your app is in horizontal compact and collapseSecondary will be called.
App orientation has suddenly stopped working as intended. I have an app with a tabBarController working mainly in portrait mode. Some VC's override this to allow landscape. The deployment target is iPhone on iOS 9.0+.
The shouldautorotate method is no longer being called anywhere in the app, but supportedInterfaceOrientations is called about 10 times (in the tabbarController) for each rotation (for different subVC's I guess).
This has all worked brilliantly before but if I check out an older branch where I know 100% that it worked, it still doesn't work. (I know this because I have a test build which works properly when I download it)
I've tried backtracking, cleaning, updating, reinstalling, re-downloading entire project, switching branches etc. but nothing works. I've gone through all warnings in the debugger output and tried a bunch of code solutions.
I'm wondering if it could be some sort of plist or project setting causing this. But, honestly, I hardly ever change project settings so I doubt it's that.
PS. This is not a duplicate of similarly titled questions. I've gone through them already. I'd be very grateful if anyone has any idea.
Autorotation is the bane of my iOS existence. There was a perfectly good way of doing this pre-iOS 6, then there was a new way of doing this in iOS 6, then another way in iOS 7, and yet another way in iOS 8. According to the UIViewController documentation:
As of iOS 8, all rotation-related methods are deprecated. Instead, rotations are treated as a change in the size of the view controller’s view and are therefore reported using the viewWillTransitionToSize:withTransitionCoordinator: method. When the interface orientation changes, UIKit calls this method on the window’s root view controller. That view controller then notifies its child view controllers, propagating the message throughout the view controller hierarchy.
Note that this method is called on the root view controller for the window, not the active/visible/whatever view controller. My root view controller dismisses any popovers then calls setNeedsLayout on its view. (I manually layout all my views so your requirements may be different.)
I was given a project that was started by someone else who no longer works here.
I have a UITabBarController which holds some UIViewControllers.
If the application is running on iOS 6, everything runs fine, However as soon as I run it on iOS 5, all UIViews are rotated 90 degrees and given an origin value of something around -100 to -300
I have been able to loop through all view controllers of the tabBar and set
myView.transform = CGAffineTransformMakeRotation(0.0);
myView setFrame:CGRectMake(0,0,1024,748);
The initial view controllers on UITabBarController appear correctly, However, if I ever try to launch a modal view controller, everything is stuffed again. including the modal.
I am running out of ideas on how I could fix this once and for all. I couldn't find anything in the code that rotates the views.
What I could deduce is
on iOS 6, the first subview of the main view holding the UITabBarController is UILayoutContainerView
but on iOS 5 the first subview is of class UIView
If this is an issue with UILayoutContainerView not being supported in iOS5, how can I make the application backwards compatible now?
Note: we only support Landscape (Right/Left) and only on iPad.
Also, I have noticed that if the user rotates the application before initialiazing the UITabBarController and its sub controllers. everything works fine. Even if you re-run the application and not rotate again, still works.
Thanks in advance
If you want your application to stick in landscape mode you the blow code, the issue resides in iOS 5, many people face this issue
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
BOOL returningValue=NO;
if (interfaceOrientation==UIInterfaceOrientationIsPortrait(interfaceOrientation))
{
returningValue=NO;
}
else if(UIInterfaceOrientationIsLandscape(interfaceOrientation))
{
returningValue=YES;
}
return returningValue;
}
Apparently, this is where I went wrong
For iOS 5
when setting the view of the main window of the application, one must use
[self.window addSubview: tabBarController.view];
Instead of (iOS6 only)
[self.window setRootViewController: tabBarController];
I am unsure how that changes everything, and the reason it won't work for iOS 5. Nevertheless, it worked.
Thanks everyone :)
I'm pretty new to MonoTouch and I'm having problems getting my app to rotate from portrait to landscape mode.
My project has two XIB files, the MainWindow added by MonoTouch and MainController.xib which I have added. The MainController has a single label and no other controls. In my Main.cs I have the following to load the MainController.xib file:
UIViewController controller = new MainController();
window.AddSubview(controller.View);
In the MainController code I added
public override bool ShouldAutorotateToInterfaceOrientation (UIInterfaceOrientation toInterfaceOrientation)
{
return false;
}
It all runs fine and the label displays but when I rotate the simulator nothing rotates. I'm sure it's something really simple that I'm getting wrong but I just can't seem to crack it.
Any help would be appreciated.
You can look at TweetStation for a sample.
In this particular case, you might want to return "true" instead of false in the sample above.
Please note that this question is from 2008 and now is of only historic interest.
What's the best way to create an iPhone application that runs in landscape mode from the start, regardless of the position of the device?
Both programmatically and using the Interface Builder.
Historic answer only. Spectacularly out of date.
Please note that this answer is now hugely out of date/
This answer is only a historical curiosity.
Exciting news! As discovered by Andrew below, this problem has been fixed by Apple in 4.0+.
It would appear it is NO longer necessary to force the size of the view on every view, and the specific serious problem of landscape "only working the first time" has been resolved.
As of April 2011, it is not possible to test or even build anything below 4.0, so the question is purely a historic curiosity. It's incredible how much trouble it caused developers for so long!
Here is the original discussion and solution. This is utterly irrelevant now, as these systems are not even operable.
It is EXTREMELY DIFFICULT to make this work fully -- there are at least three problems/bugs at play.
try this .. interface builder landscape design
Note in particular that where it says "and you need to use shouldAutorotateToInterfaceOrientation properly everywhere" it means everywhere, all your fullscreen views.
Hope it helps in this nightmare!
An important reminder of the ADDITIONAL well-known problem at hand here: if you are trying to swap between MORE THAN ONE view (all landscape), IT SIMPLY DOES NOT WORK. It is essential to remember this or you will waste days on the problem. It is literally NOT POSSIBLE. It is the biggest open, known, bug on the iOS platform. There is literally no way to make the hardware make the second view you load, be landscape. The annoying but simple workaround, and what you must do, is have a trivial master UIViewController that does nothing but sit there and let you swap between your views.
In other words, in iOS because of a major know bug:
[window addSubview:happyThing.view];
[window makeKeyAndVisible];
You can do that only once. Later, if you try to remove happyThing.view, and instead put in there newThing.view, IT DOES NOT WORK - AND THAT'S THAT. The machine will never rotate the view to landscape. There is no trick fix, even Apple cannot make it work. The workaround you must adopt is having an overall UIViewController that simply sits there and just holds your various views (happyThing, newThing, etc). Hope it helps!
From the Apple Dev Site:
To start your application in landscape
mode so that the status bar is in the
appropriate position immediately, edit
your Info.plist file to add the
UIInterfaceOrientation key with the
appropriate value
(UIInterfaceOrientationLandscapeRight
or
UIInterfaceOrientationLandscapeLeft),
as shown in Listing 2.
Listing 2: Starting your application
in landscape mode
<key>UIInterfaceOrientation</key>
<string>UIInterfaceOrientationLandscapeRight</string>
Summary and integration from all the posts, after testing it myself; check the update for 4.x, 5.x below.
As of 3.2 you cannot change the orientation of a running application from code.
But you can start an application with a fixed orientation, although doing so this is not straightforward.
Try with this recipe:
set your orientation to UISupportedInterfaceOrientations in the Info.plist file
in your window define a 480x320 "base view controller". Every other view will be added as a subview to its view.
in all view controllers set up the shouldAutorotateToInterfaceOrientation: method (to return the same value you defined in the plist, of course)
in all view controllers set a background view with
self.view.frame = CGRectMake(0, 0, 480, 320)
in the viewDidLoad method.
Update (iOS 4.x, 5.x): the Apple iOS App Programming Guide has a "Launching in Landscape Mode" paragraph in the "Advanced App Tricks" chapter.

interface builder landscape design
interface builder landscape design-1
First I set in info.plist
<key>UIInterfaceOrientation</key>
<string>UIInterfaceOrientationLandscapeRight</string>
then I put this code in applicationDidFinishLaunching:
CGAffineTransform rotate = CGAffineTransformMakeRotation(1.57079633);
[window setTransform:rotate];
CGRect contentRect = CGRectMake(0, 0, 480, 320);
window.bounds = contentRect;
[window setCenter:CGPointMake(160.0f, 240.0f)];
This way I can work on the view in Interface Builder in landscape mode.
sasb's and michaelpryor's answer appears to be correct, but if it's not working for you, try this alternative:
- (void)applicationDidFinishLaunchingUIApplication *)application {
application.statusBarOrientation = UIInterfaceOrientationLandscapeRight;
}
Or this one:
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
Or this one:
[application setStatusBarOrientation: UIInterfaceOrientationLandscapeRight animated:NO];
You may also have to call window makeKeyAndVisible; first.
A few links: Developing in landscape mode, iPhone SDK: How to force Landscape mode only?
#Robert: please refer to The iPhone SDK, NDA, and Stack Overflow.
I'm surprised no one has come up with this answer yet:
In all my tests when a dismissing a modal view controller the parent view controller's preferred orientation set in shouldAutorotateToInterfaceOrientation is honored even when part of a UINavigationController. So the solution to this is simple:
Create a dummy UIViewController with a UIImageView for a background. Set the image to the default.png image your app uses on startup.
When viewWillAppear gets called in your root view controller, just present the dummy view controller without animation.
when viewDidAppear gets called in your dummy view controller, dismiss the view controller with a nice cross dissolve animation.
Not only does this work, but it looks good! BTW, just for clarification i do the root view controller's viewWillAppear like this:
- (void)viewWillAppear:(BOOL)animated
{
if ( dummy != nil ) {
[dummy setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:dummy animated:NO];
[dummy release];
dummy = nil;
}
...
}
The latest iPhone OS Programming Guide has a full section on this, with sample code. I am sure this is a recent addition, so maybe you missed it. It explains all the conditions you have to comply with; basically...
set the Info.plist properties (this changes the position of the status bar, but not the view)
rotate your view manually around its center, on either your UIViewController viewDidLoad: method or your applicationDidFinishLaunching: method or implement auto rotation ("Autoresizing behaviors", page 124)
Look for "Launching in Landscape Mode", page 102.
See this answer: Landscape Mode ONLY for iPhone or iPad
add orientation to plist
shouldAutorotateToInterfaceOrientation = YES in all files
Although if you're using mixed modes, you might be better off with
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
