The Screen UI is developed for 3:2, but when I run the app in iOS Simulator for iphone 5 and above, I see there is a white patch below in the bottom of the screen. The rest of the screens are appearing correctly.
- (void)applicationDidFinishLaunching:(UIApplication *)application {
[self startup];
[window addSubview:loginViewController.view];
//For Eula
NSDictionary *eulaDict = [EULAController getEULADictionary];
if (eulaDict == nil || [ self checkForVersionChange] == TRUE) {
eulaController = [[EULAController alloc] initWithNibName:#"eula"bundle:[NSBundle mainBundle]];
//temp fix as for some reason this is showing up 20 pixels shifted upwards. if this works in your scenario then remove this adjustment
CGRect frame1 = CGRectMake(0,20,320,460);
[eulaController.view setFrame:frame1];
[window addSubview:eulaController.view];
}
[self updateVersionAndBuild];
[window makeKeyAndVisible];
}
Not sure, why its not fitting the entire screen. I didn enable athe AutoLayout option but it didnt help, as during the launch of the app, it stops for iphone 5/6.
Thanks in advance !
I guess you are missing the Default-568h#2x.png default launch image...
If so, just add one to your project and it will work.
You've hardcoded the frame to iPhone 4 size:
CGRect frame1 = CGRectMake(0,20,320,460);
You've said your using autoLayout. I'd remove this and use autoLayout constraints instead and it will scale.

I have a universal application running both on iPads and iPhones. The application starts with a .xib file, built in interface builder, which acts as the launch image. Once the app launched, it switches to the appropriate view controller based on device size set in the app delegate:
CGSize screenSize = [[UIScreen mainScreen] bounds].size;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
if (screenSize.height <= 568.0f) {
// iPhone 4, 4S, 5, 5C, 5S, SE
self.viewController = [[iPhoneSmallViewController alloc] init];
} else {
// All other iPhones
self.viewController = [[iPhoneLargeViewController alloc] init];
}
} else {
// All iPad models
self.viewController = [[iPadViewController alloc] init];
}
The iPad view controller supports all interface orientations (set in app targets/main setup page), but on iPhones I only allow portrait mode restricted in the view controller as such:
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);
}
I have two problems with this method:
If the iPhone is held horizontally, the app still loads in portrait mode (as per the restrictions, which is all good) but all measurements are in landscape upon initialization. UI elements stick out on the side because they were measured for a landscape view but placed on a portrait.
I use the window's size to set up everything inside the view by initializing the following variable in the ViewDidLoad method:
windowSize = [[UIScreen mainScreen] bounds].size;
Tt gives me landscape dimensions in phone is held horizontally, even though landscape mode is not allowed.
If the app loads with landscape measurements initially, all my sorting of screen sizes in the app delegate are off since I identify iPhone models by measuring screen width that is only good in portrait mode.
Question: does anyone have a way to handle this complex problem in an elegant and simple way?
Some additional info: I use Xcode 10, support all the way back to iOS9 and do everything programmatically in Objective C.
p.s: I think this method worked before but not any more in iOS 12. But I could be wrong...
Edit: I provide an image of what I want to accomplish, and all help would be greatly appreciated. As I said, this has worked before (the app is quite old), but in recent iOS releases got increasingly buggy and desperately needs a cleanup, which is what I need help with.
One thing that might solve my problem, is if I could somehow restrict interface orientations based on device type in the launchScreen.xib, as I believe that is what causes the faulty behavior on iPhones.
Maybe this SO will be helpful,
They are detecting the device orientation and then rotating the view, look at first answer:
Change orientation programmatically with button - iOS
UIInterfaceOrientation currentOrientation = [UIApplication sharedApplication].statusBarOrientation;
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:value forKey:#"orientation"];
[UIViewController attemptRotationToDeviceOrientation];
A better way to detect device is explained here:
iOS detect if user is on an iPad
if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad )
{
return YES; /* Device is iPad */
}
I've been experimenting with this for days, and worked out a solution. Although this is probably not the most elegant way to do it, so if anyone has a better solution, please feel free to post it.
It is important to allow all interface orientations in the info.plist because I was unable to restrict them based on device size in the launchScreen.xib.
Create the universal launch screen that supports both iPads and iPhones. Because all interface orientations are allowed in the info.plist, this will have no restrictions.
Below is my current method in the app delegate. This is not the best way to do identifying the smaller iPhones (which I need for reasons... :), but because of the size differences, this works quite well.
At this point, the phone can be in any of the four interface orientations set in the info.plist, but because only the small handsets have a 320-width it is easy to catch it:
// Get screen size
CGSize screenSize = [[UIScreen mainScreen] bounds].size;
// Determine device based on screen dimensions
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
if ( (screenSize.height == 320.0f) || (screenSize.width == 320.0f) ){
// iPhone 4, 4S, 5, 5C, 5S, SE
self.viewController = [[iPhoneSmallViewController alloc] init];
} else {
// iPhone 6, 6S, 6P, 6SP, 7, 7P, 8, 8P X, XS, XM, XR
self.viewController = [[iPhoneLargeViewController alloc] init]; //Same as previous
}
} else {
// All iPad models
self.viewController = [[iPadViewController alloc] init];
}
Restrict interface orientations in the iPhone view controllers (all other view controllers will inherit the ones we set in the info.plist).
Do it like so:
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait);
}
There is another trick we need to do for the above to work though. When the window loads for the first time, it will not take into consideration the restriction we added to the view controller. That means, if we do our setup in the viewDidLoad method, we will receive landscape screen dimensions if the device is held horizontally (even though this orientation is not allowed). Restriction will be applied once the viewDidLoad method has concluded.
Therefore, to prevent buggy behavior, you need to create a separate method in which you do your setup (such as postViewDidLoad) and call it once the real viewDidLoad had concluded:
- (void) viewDidLoad
{
[super viewDidLoad];
[self performSelector:#selector(postViewDidLoad) withObject:nil afterDelay:0.0f];
}
In this method, you will get access the real screen size based on your restrictions you set in the supportedInterfaceOrientations method.
And that is basically it. If you have multiple views, all with different restrictions, just follow steps 4 and 5 in each of them to properly setup your workflow.
I am trying to cover status bar with my own view and to do that I calculcate frame for my view by doing something like that (also after rotation):
UIScreen *screen = [UIScreen mainScreen];
CGRect statusBarFrame = [UIApplication sharedApplication].statusBarFrame;
For iOS8+ (because since ios8 UIScreen is orientantion-dependant):
CGRect frame = [screen.coordinateSpace convertRect:statusBarFrame toCoordinateSpace:screen.fixedCoordinateSpace];
[self setFrame:frame];
For iOS7:
[self setFrame:statusBarFrame];
It works just fine for iOS8 and below but when building my app with Xcode 7 beta 4 and iOS 9 SDK something is wrong when starting app in landscape or upsidedown (it works fine if app starts in portrait) ...
ie. when I start the app while Upsidedown the custom uiwindow which should cover status bar will always end up at the bottom side of screen, any ideas what might be wrong?
Without additional information, the best solution would be to simply hide the status bar. If you still want the "status bar" for animation purposes or some other reason, the typical solution in this scenario is to simulate it by calling
- (UIView *)snapshotViewAfterScreenUpdates:(BOOL)afterUpdates on UIScreen
and use the returned view as the background for whatever view/window you're presenting. As of iOS 9, there's no public method that'll allow you to get the specific behavior you specified.
I am experiencing an issue when using the iPad Camera in iOS 8. I've seen some older questions and a thread on the Apple Developer Forums from during the beta but still haven't find a solution.
There seems to be two parts to this issue.
1) The camera itself rotates when the device orientation rotates, eg the world is on its side
2) When opening the camera in Landscape, the overlay does not appear. When opened in Portrait it is fine.
It is an app using iOS7 as the Base SDK, problem only occurs when running the app on a device that has been upgraded to iOS8. The app is not using storyboards, it is using nibs.
I'm hoping to push out a fix for this with Xcode 5.1.1 before moving onto the iOS8 specific fixes and using it as a Base SDK in the next version.
Here is my code to bring up the camera:
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES) {
// Create Camera
imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
imagePicker.showsCameraControls = NO;
// Set up custom controls view
[[NSBundle mainBundle] loadNibNamed:#"OverlayView" owner:self options:nil];
self.overlayView.frame = imagePicker.cameraOverlayView.frame;
imagePicker.cameraOverlayView = self.overlayView;
self.overlayView = nil;
// Show Camera
[self presentViewController:imagePicker animated:NO completion:nil];
[imagePicker release];
}
I have also tried
And the Layout of the Toolbar (sitting at the bottom) of the OverlayView:
If I change that to sit "at the top" it appears in both portrait and landscape! So it must have to do with the view/window/something size, though it's strange how its behaviour would change when the layout has stayed the same.
I have tried it with both showsCameraControls = YES and hashing out the OverlayView block, and problem #1 persists so it's not to do with the overlay at app.
I'm hoping someone has found an answer to this, it seems like quite a common problem.
Please let me know if you need any further details.
Edit 1: Fixed the Overlay (Issue #2)
It wasn't applying the orientation to the OverlayView, fixed it like this:
// Grab the window frame and adjust it for orientation - from http://stackoverflow.com/a/15707997/520902
UIView *rootView = [[[UIApplication sharedApplication] keyWindow]
rootViewController].view;
CGRect originalFrame = [[UIScreen mainScreen] bounds];
CGRect screenFrame = [rootView convertRect:originalFrame fromView:nil];
...
self.overlayView.frame = imagePicker.cameraOverlayView.frame;
I suspect that it's related to the camera not realising it's orientated too, will keep searching for a fix for Problem #1.
Edit 2: Update on Issue #1
Looks like the camera rotating might be an Apple issue. On iOS8 if you open up the Contacts app, edit a contact and choose 'Take Photo', the exact same issue occurs - in a default Apple app!
I still can't find a fix so I am just destroying and recreating the imagePicker on each orientation change for now, it's ugly but will suffice until Apple release a fix or a better solution pops up.
Apple fixed this problem in iOS 8.1.
I am using a UIPopoverController and populating it with a MPMediaPickerController to choose songs from iPod library. I have got it working just fine. However, I added a completely unrelated feature ( touch a button and image scale to large size ) and now the UIPopoverController behaves strangely only after using the new feature.
After using the button scale feature, the UIPopoverController appears in a strange manner. It looks like it is animating from a rotated state off the screen and lands in the correct place, but the expected behavior is that it should just appear in the right location.
// code for if the interface is a an iPhone, do not use popup
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
[self presentModalViewController:picker animated:YES];
// code if not iPhone uses popover media picker
else {
UIPopoverController* pop =
[[UIPopoverController alloc] initWithContentViewController:picker];
self.currentPop = pop;
// checks if the iPad is portrait or landscape and displays the popover media picker accordingly
if (vertMode == TRUE)
{
// if in portrait mode
[pop presentPopoverFromRect:CGRectMake(668.0f, 846.0f, 10.0f, 10.0f) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:NO];
// otherwise if in landscape mode
}
else if (vertMode == FALSE)
{
[pop presentPopoverFromRect:CGRectMake(900.0f, 580.0f, 10.0f, 10.0f) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:NO];
}
[pop release];
}
}
OK, well I feel a bit silly answering my own question, but I hope that it may help someone else in the future.
I am not exactly sure why, but in my function for the button that scales the image to a large size, I forgot to add:
[UIView commitAnimations];
the intention of that was to complete the animated movement of the scaling image, I am guessing because I never commit the animation, that it was still in some state of trying to animating things. Then when I called my popup , it made the weird animation occur.
So I fixed this by just adding the above one line!
I feel SO much better figuring this one out! I hope it helps someone else out there.
I have a split view app running fine on the iPad. It is using the default setup (Popover in Portrait, table view on the left in landscape). The views shift correctly once the app is running. The problem I am seeing is that when the app starts (in the simulator) running in landscape mode the UI paradigm is the one intended for Portrait mode (Master List is a popover) is what loads.
I am thinking this is some strangeness with the simulator, or I am missing an option on my main view controller.
I ran into the same problem as is described here. The solution was, embarrassingly, as simple as manually setting the view's frame before adding it to the window.
Just check the interface orientation and, if it's landscape, switch the application frame width and height dimensions (i.e., width becomes height, height becomes width).
CGRect frame = [[UIScreen mainScreen] applicationFrame];
switch(controller.interfaceOrientation){
case UIInterfaceOrientationPortrait:
case UIInterfaceOrientationPortraitUpsideDown:
[controller.view setFrame:frame];
break;
case UIInterfaceOrientationLandscapeLeft:
case UIInterfaceOrientationLandscapeRight:
[controller.view setFrame:CGRectMake(frame.origin.x, frame.origin.y, frame.size.height, frame.size.width)];
break;
}
Adding this as an answer as well in the hopes it will be more apparent to those in need of the same fix.
I solved this. I was waiting for an external XML stream to be loaded & parsed. As a result I was loading the window with the splitViewController view AFTER my applicationDidFinishLaunching method.
Adding:
[window addSubview: splitViewController.view];
[window makeKeyAndVisible];
back into that method fixed the orientation recognition
I succeeded into displaying a loading view by doing
[window addSubview:self._splitViewController.view];
[window addSubview:self._myLoadingView];
self._splitViewController.view.hidden = YES;
[window makeKeyAndVisible];
[self loadAllDatas];
self._splitViewController.view.hidden = NO;
i works fine
It doesn't work correctly because the default detail view controller of UISplitViewController is just a plain UIViewController. The shouldRotate method of UIViewController returns YES for portrait mode only.
Adding a generic UIViewController returning YES in shouldRotate for all orientations solved the problem for me.
