Okay guys, maybe you can help me out with this one. I'm about ready to pull my hair out.
Recently I decided to upgrade my app and make it look better, and with that I wanted to move it into full support for iPad platforms as well. For a while everything worked great. Just press copy MainWindow.xib for iPad, add the views that I used on the iPhone configurations, and everything should be great, but that didn't work too well. Take a look:
Here is the iPhone screenshot:
Here is the iPad screenshot:
Where's the tab bar? I don't understand! I added the initial view when I was first putting it together, but when I linked all of the IBOutlets to the proper pieces, the tab bar no longer shows up.
Screenshot of IB:
Tab Bar properties:
Tint: A bluish color
Image Tint: A goldish color
Mode: Scale to fill
Tag: 0
User Interaction Enabled: (Checked)
Multiple Touch: (Unchecked)
Alpha: 1
Opaque: (Checked)
Hidden (Unchecked)
Clears Graphic Context: (Checked)
Clip Subviews: (Unchecked)
Autoresize Subviews: (Checked)
Stretching: (x,y,w,h):(0,0,1,1)
The viewController.h file is a delegate for UITabBar, UITextField, and UITextView
ViewDidLoad (bar is the IBOutlet for the tab bar):
- (void)viewDidLoad
{
[super viewDidLoad];
[self playMovieIntro];
NSURL *url = [NSURL URLWithString:#"http://www.faithlifefellowship.us/Audio/Sermons/NewSermonBanner.png"];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *image = [UIImage imageWithData:data];
if(!image == NULL)
{
NewSermonBanner.image = image;
}
series = [[Series alloc] init];
SeriesName = #"";
NSRange range = [[[UIDevice currentDevice] name] rangeOfString:#"iPad"];
int i = 0;
if(range.location != NSNotFound)
i = 1;
bar.selectedItem = hometab;
//set delegates
[bar setDelegate:self];
[personalName setDelegate:self];
[personalEmail setDelegate:self];
[content setDelegate:self];
[prContent setDelegate:self];
[prName setDelegate:self];
[prEmail setDelegate:self];
}
I'm stumped. If you have any ideas or need any more information, let me know.
Thanks!
I'm going to give you a few things I'm getting in order to fix this. It will be tons easier if you could upload the source code for me/us to download and be able to pinpoint the problem.
Sometimes (I can't remember exactly when) I've had my navigation bar not show up because it was missing a connection.
Make sure you are not hiding the tab bar anywhere in code, though it doesn't seem to be the case since it shows up on iPhone.
Otherwise I'm gonna take a guess and say it's something in the NIB. Here are some things you can try:
Check all your connections to outlets
Make sure your objects in the NIB are of the correct class
Verify that the tab bar's "hidden" property is not check in Interface Builder
Compare and verify all the structure of the NIB file between iPhone and iPad
These are just some ideas :) again if you can post the code it would be fantastic.
Let us know how it goes,

I had this problem with a app that support both iPhone and iPad. Make sure 'is initial view controller' is checked for the UITabBarController when you examine the view controller using the object inspector. When you do this, xcode will display a 'inbound' arrow on the left side of the view controller if you're using storyboards.

As weird as it sounds...
App loaded through test flight or iTunes does not show image on the screen, but it does when it is loaded through Xcode. I believe the UIImageView is there, and the UIImage is loaded.
App loaded through the Xcode works.
If the device is connected to the Xcode and debugging, device connected with USB cable. App works despite the load method...
Core data seems to works in all cases.
Any idea, somebody has seen something similar. I am quite lost.
Also if you have any tip on how to debug this on the device I will appreciate it.
The few code I think it is involve.
I am loading the UIImage from disk using
UIImage * previewImage = [UIImage imageWithContentsOfFile:path];
The image is located in Documents Directory fileName is the input
NSURL *documentsFolderURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
NSString *documentsFolderPath = [documentsFolderURL path];
if (![_documentsDirectory isEqualToString:documentsFolderPath]) [self generateLocaFolderPath];
NSString *returnedPath = [_documentsDirectory stringByAppendingPathComponent:fileName];
return returnedPath;
and setting the image in the imageView with
previewView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, frameImageThumbnail.size.width, frameImageThumbnail.size.height)];
[previewView setImage:previewImage];
Everything else seems to work well...
My first question!!! Thanks for reading!
_ edit _
I had the strong believe now that the problem is not in the UIImage, I have use the same methods in other parts of the app and it is working fine.
But now I believe the problem is in the animation I perform to the UIView that contains the UIImageView.
[_view setFrame:frameImageThumbnail];
[_view setClipsToBounds:YES];
[_view setAutoresizesSubviews:YES];
[_image setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
[_view addSubview:_image];
[UIView animateWithDuration:0.4
delay:0.1
options:UIViewAnimationOptionCurveEaseInOut
animations:^(void){
CGRect destination1Frame = _view.frame;
//... some complicated calculations with the rect ...
[_view setFrame:destination1Frame];
[UIView transitionFromView:_customView toView:_view duration:0 options: UIViewAnimationOptionShowHideTransitionViews completion:^(BOOL finisehdCompletion){
//stop showing video in _customView
}];
}];
I am using NSAutolayout in the storyboard. Though my application only allows one landscape orientation. No idea if all this meshing up with the frames it is making.
dizzy to the poor auto layout guy...
Make sure you have / your image is set in Copy Bundle Resources. You can check if your image path is valid also. But I think the image is not set to copy at Build Phases.
I had the same problem.. Haven't find a correct solution.
But I deleted the image(check if it's deleted in ur Bundle resources), then put the image again, with ANOTHER name.
It worked for me. It's a temporary solution, idk if it's an apple bug or what.
Ok After more than 20 ipa files build and installed in my devices. In all this process to get rid of the problem I removed the _view from the storyboard, and initiallize the view programmatically. I remember that _view was originally set to (weak, nonatomic) property because was made with the storyboard, this super nice ctrl+.
That was I change I made, weak to Strong, and works now.
I don't know why it didn't work only when the program was install through iTunes with the ipa file or through the test flight app. That is still a mystery to me.
I have a custom UIView that I have created to display my custom buttons and toolBar. When I first called for it to show, the bar is on top of the Shutter (which is good). But after the camera is loaded, the shutter comes in front of it, then opens.
If you look at the native camera.app, it doesn't do this. The toolbar stays there the whole time. Here is my code:
// .h
UIImagePickerController *theCamera;
#property (nonatomic, retain) UIImagePickerController *theCamera;
// .m
theCamera = [[UIImagePickerController alloc] init];
theCamera.delegate = self;
theCamera.sourceType = UIImagePickerControllerSourceTypeCamera;
theCamera.showsCameraControls = NO;
theCamera.toolbar.alpha = 0;
theCamera.navigationBarHidden = YES;
theCamera.toolbarHidden = YES;
theCamera.wantsFullScreenLayout = YES;
theCamera.cameraViewTransform = CGAffineTransformMakeScale(1.25, 1.25);
UIImageView *tabBarBack = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"tab_bar_back.png"]];
tabBarBack.frame = CGRectMake(0, 422, 320, 58);
[customView addSubview:tabBarBack];
theCamera.cameraOverlayView = customView;
[self presentModalViewController:theCamera animated:YES];
Obviously there are more buttons I add to the customView, but you get the concept.

AVCaptureSessionDidStartRunningNotification
This is when the iris open animation begins. If you add a cameraOverlayView during this time, it will be properly covered up by the iris. It is posted at the same time as that PL… private notification. This is a documented approach that does not risk app rejection.
AFAIK there is no direct way to do this. If you use cameraOverlay, you will get shutter for the complete screen.
How ever there are some alternate methods (playing around with the view hierarchy) that will help you in making your preview screen as parent view. I am not sure if this approach is correct as per app store guidelines.
have a look at Hide/Show iPhone Camera Iris/Shutter animation for better understanding on how to achieve this.
On iOS 6+, if you've added your controller as the delegate for the UIImagePickerController, this code should ensure that the shutter stays behind your cameraOverlayView:
- (void) navigationController:(UINavigationController*) navigationController willShowViewController:(UIViewController*) viewController animated:(BOOL) animated {
self.imagePickerController.cameraOverlayView = ...; // your camera overlay view
}
I haven't tested on versions of iOS prior to iOS 6 though.
I admit I'm a newby to Objective-C but came pretty far, I guess. Now I'm having an issue and would need some help.
In my app I display images in portrait modes amongst other information and want to display them full screen in landscape mode. I learned that you'd do this defining a Landscape m, h and nib file and load this view when the device is moved to landscape orientation (working with an observer), right?
In portrait mode the images in the end depend on user interaction so the Landscape class needs to be told, which image to display. I created a putImage method in the Landscape class
-(void) putImage:(NSString *)theImage {
pict.image = [UIImage imageNamed: theImage];
NSLog(#"PICT %#",pict.image);
NSLog(#"IMAGE %#",theImage);
}
and call it from the portrait one and here comes the issue:
NSString *actualImage = [NSString stringWithFormat:#"Picture%i.jpg",selected];
pict.image = [UIImage imageNamed: actualImage];
[landscapeViewController putImage:actualImage];
that works perfectly every time except the very first one. So whatever I do I need to first make the App load a new image plus change to landscape orientation (being displayed no image) in any manner. Then after it always works displaying the correct images.
I added debug information and see that the correct image is assigned to pict in landscape class - however it seems it needs to be displayed before it really sets the image.
Any help you guys could give?
Not sure if this it it since your example code is pretty sparse. But when you load your first picture do you do that in init? If so, try to do it in viewWillAppear or viewDidAppear.
thank you for all the hints and tries to help. Now I found the solution myself ... here's what I did:
1) in the LandscapeViewController.h I defined an NSString:
#interface LandscapeViewController : UIViewController
{
IBOutlet UIImageView *pict;
NSString *actualImage;
}
2) I changed the putImage method to only assign the image name to my local NSSTRING variable:
-(void) putImage:(NSString *)theImage {
actualImage = theImage;
[actualImage retain];
}
3) loading the image I only do in viewWillAppear:
- (void)viewWillAppear:(BOOL)animated {
pict.image = [UIImage imageNamed: actualImage];
[super viewWillAppear:animated];
}
So the answer to my question is almost answered - I guess that this issue arose because I did set the image before I loaded the view first time so that it was not instanciated. I was able to call the method but had no Image Object to set ... does that sound logical to you guys?
Thank you all again!
iPad question:
We have views that we're initializing from .xibs, with each .xib containing both landscape and portrait layouts.
The first view we load respects the orientation of the device, but any subsequent views seem to have confusion over which orientation they should be using. Or, rather, they seem to ignore orientation altogether and go with whichever orientation the .xib file was saved with. (i.e. We saved a .xib file in landscape, and even though the device was held in portrait position, it loaded the view from the .xib with a landscape layout.)
This is how we're calling in these views:
Settings *settingsTEMP = [[Settings alloc] init];
self.settings = settingsTEMP;
[self.view insertSubview:settings.view atIndex:0];
[settingsTEMP release];
The first of the calls (the one that respects the device's orientation) is in the viewDidLoad. The second, which uses a different view (the one that doesn't respect the device's orientation) is in a method that's called after a button is pressed, but uses the same syntax.
If we put both into viewDidLoad, they both respect the orientation.
We've tried searching for anyone having similar issues but have been thus far unsuccessful. Thanks in advance for any help you can provide.
I use the following
UIInterfaceOrientation toInterfaceOrientation = self.interfaceOrientation;
if ((toInterfaceOrientation == UIDeviceOrientationLandscapeLeft) ||
(toInterfaceOrientation == UIDeviceOrientationLandscapeRight))
{
NSLog(#"vSettings UIDeviceOrientationLandscape");
CGRect contentRect = CGRectMake(0,0,1024,768);
vSettings.bounds = contentRect;
CGRect myFrame = vSettings.frame;
myFrame.origin.x = 0.0;
myFrame.origin.y = 0.0;
vSettings.frame = myFrame;
UIImage *image;
image = [UIImage imageNamed: #"Default-Landscape.png"];
[backGroundSettings setImage:image];
}
I hate having to do this as it seems a right fudge but it works for me. Called just after I create the view.
I'm using MPMoviePlayerViewController - with the player controls set to: MPMovieControlStyleFullscreen
I'm having a problem with some of buttons that are in MPMovieControlStyleFullscreen: forward, reverse, and fullscreen (the one with the arrows pointing at eachother).
I would like to either remove the forward, reverse, and fullscreen buttons or control what they do when the user taps them.
Thank you!
There isn't a way to customize the MPMovieControlStyle values provided by Apple. What you need to do is is turn off the Apple controls (MPMovieControlStyleNone) and then create your own custom controls. Apple is fine with you putting your own UIViews in to the hierarchy here, so you can get started with something like this:
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: YOUR_URL];
moviePlayer.controlStyle = MPMovieControlStyleNone;
UIView *movieView = moviePlayer.view;
[movieView addSubview: _movieControlsView];
[movieView bringSubviewToFront: _movieControlsView];
Where _movieControlsView was set up earlier in code or in IB.
Aesthetically, you can do what you want, but I would recommend sticking with something that looks like Apple's choices so as not to confuse the user. For the project I just finished, I created a transparent button the exact size of the movie player. Clicking the button fades in a control bar on the bottom with my custom controls. If one of the controls isn't clicked, the control bar fades back out again after a few seconds.
First off, MPMoviePlayerController is a little different than MPMoviePlayer*View*Controller, so some of these answers lead to problems when converting applications that were built in an iOS 4.3+ environment.
I've built some apps using MPMoviePlayerController that worked fine when built in iOS 3.2. When I rebuilt it with XCode 3.2.6, (iOS 4.3), the videos don't even play on the iPhone. I since fixed that by adding the MPMoviePlayerController instance to a subView, then presenting a modal (Player is a UIViewController) with the movplayer in fullScreenMode:
//from didSelectRowAtIndexPath
Vid *selected = [items objectAtIndex:position];
player = [[Player alloc] init];
movplayer = [[MPMoviePlayerController alloc] initWithContentURL:selected.vidURL];
movplayer.view.frame = player.view.bounds;
movplayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight |
UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
[player.view addSubview:movplayer.view];
[self presentModalViewController:player animated:YES];
[movplayer setFullscreen:YES animated:NO];
[movplayer play];
[player release];
//movplayer is released inside - (void)exitedFullscreen:(NSNotification*)notification
This was done on account of the UINavigationBar being half cut off when rotating.
When I got to the iPad version of the app the modal option wouldn't work aesthetically. It was also having the UISplitViewController navBar and toolbars half cut off when rotating in full screen mode. So I tried implementing MPMoviePlayerViewController instead of MPMoviePlayerController. With this conversion, XCode gave me errors when trying to set:
movplayer.controlStyle = MPMovieControlStyleEmbedded;
The proper way to do this with a MPMoviePlayerViewController is:
movplayer.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
When the player is added as a subView, the pinch gestures will toggle the player between fullScreen and the size of your parentView (player.view.bounds) smoothly, as well as preserve the toolbars and navBars native to the parent.
//iPad version with a view (viewForMovie) inside the DetailViewController
movplayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[current vidURL]];
movplayer.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
movplayer.view.backgroundColor = [UIColor clearColor];
movplayer.view.frame = viewForMovie.bounds;
[viewForMovie addSubview:movplayer.view];
So these two examples show some workarounds for those who want to convert their iPhone or iPad apps to a newer iOS version.
Try setting MPMovieControlStyle of your MPMoviePlayerController object to MPMovieControlStyleNone
