I followed the instructions in the read me file exactly, but for some reason, in my app, every time I hit the UIButton corresponding to the code to play the sound "[soundA play]; the app just crashes without any detailed error description except for lldb. I'm using Finch because it plays the audio using OpenAL, and I need to use OpenAL for the type of app I'm making because AVAudioPlayer or System Sounds are not usable for what I'm making. Here is the code that I am using.
Main file:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
soundFactory = [[FIFactory alloc] init];
engine = [soundFactory buildSoundEngine];
[engine activateAudioSessionWithCategory:AVAudioSessionCategoryPlayback];
[engine openAudioDevice];
soundA = [soundFactory loadSoundNamed:#"1.caf" maxPolyphony:16 error:NULL];
soundB = [soundFactory loadSoundNamed:#"2.caf" maxPolyphony:16 error:NULL];
soundC = [soundFactory loadSoundNamed:#"3.caf" maxPolyphony:16 error:NULL];
soundD = [soundFactory loadSoundNamed:#"4.caf" maxPolyphony:16 error:NULL];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
} else {
return YES;
}
}
- (IBAction) PlaySoundA {[soundA play];}
- (IBAction) PlaySoundB {[soundB play];}
- (IBAction) PlaySoundC {[soundC play];}
- (IBAction) PlaySoundD {[soundD play];}
#end
Header file:
#import <UIKit/UIKit.h>
#import "FISoundEngine.h"
#import "FIFactory.h"
#import "FISound.h"
#interface ViewController : UIViewController {
FIFactory* soundFactory;
FISoundEngine* engine;
FISound* soundA;
FISound* soundB;
FISound* soundC;
FISound* soundD;
}
#end
Any help would be appreciated! Thanks!
Most likely the sound player cannot find your sound file. try right clicking on the audio file and selecting view in finder. make sure the file is actually in your project directory and not

Please note that the answer below - do not work for iOS6 so I still need an answer!
My application is enabled only for Portrait mode.
However, if I embed a UIImagePickerController inside as a subview, and rotate the device, the top and bottom bar stays in the same location, however UIImagePickerController does rotate.
How can I prevent it from rotating?
This is the code:
[self.view.window addSubview:self.imagePickerController.view];
self.imagePickerController.showsCameraControls = NO;
self.imagePickerController.view.frame = CGRectMake(0, 90, 320, 320);
self.imagePickerController.allowsEditing = NO;
EDITED
I am using iOS6 where shouldAutorotate is not being calle
Add this UIImagePickerController category in your class,
#interface UIImagePickerController(Nonrotating)
- (BOOL)shouldAutorotate;
#end
#implementation UIImagePickerController(Nonrotating)
- (BOOL)shouldAutorotate {
return NO;
}
#end
include the following in your controller this will work, I'm just creating the category of UIImagePickerController
#interface UIImagePickerController (private)
- (BOOL)shouldAutorotate;
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;
- (NSUInteger)supportedInterfaceOrientations;
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
#end
#implementation UIImagePickerController (Private)
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotate {
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#end
One possibility is to override the
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;
method of UIImagePickerController. I'm not sure if this is the best possibility but it will work.
So if you only want your UIImagePickerController to be rotated to portrait use the following code
#interface PortraitUIImagePickerController : UIImagePickerController
#end
And the implementation should look like the following
#implementation PortraitUIImagePickerController
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return UIInterfaceOrientationIsPortrait(toInterfaceOrientation);
}
#end
The category in the most voted answer works, but since it is discouraged to use categories, you can also make a subclass of UIImagePickerController and use that.
If you want to avoid rotating of the UIImagePickerController add the following class
UINonRotatableImagePickerController.h
#interface UINonRotatableImagePickerController : UIImagePickerController
#end
UINonRotatableImagePickerController.m
#implementation UINonRotatableImagePickerController
- (BOOL)shouldAutorotate
{
return NO;
}
#end
You have to change the UIImagePicker class in the storyboard to use UILandscapeImagePickerController, or if you allocate it in code, change
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
to
UIImagePickerController *picker = [[UINonRotatableImagePickerController alloc] init];
and include UINonRotatableImagePickerController.h in your code.
I'm having what seems to be a fairly common problem, but my searches and implementations of solutions have not worked out.
I've built a Cocos2d game that is intended to be landscape only, but needs to access Gamecenter. Gamecenter is working, with portrait mode enabled, but it's also allowing the game to flip to portrait mode too.
I've attempted the following fixes:
Game center login lock in landscape only in i OS 6
GameCenter authentication in landscape-only app throws UIApplicationInvalidInterfaceOrientation
Error in iOS 6 after adding GameCenter to a landscape-only cocos2d app
Cocos 2d 2.0 shouldAutorotate not working?
I believe the problem is that I've built the game using CCLayers instead of UIViewControllers
Example:
MenuLayer.h
#interface MenuLayer : CCLayer <GKAchievementViewControllerDelegate, GKLeaderboardViewControllerDelegate, UINavigationControllerDelegate>{
..my header info..
}
MenuLayer.m
...
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
-(BOOL)shouldAutorotate {
return [[UIDevice currentDevice] orientation] != UIInterfaceOrientationPortrait;
}
-(void)authenticateLocalPlayer
{
GKLocalPlayer * localPlayer= [GKLocalPlayer localPlayer];
if(localPlayer.authenticated == NO)
{
NSString *reqSysVer = #"6.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending)
{
[[GKLocalPlayer localPlayer] setAuthenticateHandler:(^(UIViewController* viewcontroller, NSError *error) {
if (viewcontroller != nil) {
AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
[[app navController] presentModalViewController:viewcontroller animated:YES];
}else if ([GKLocalPlayer localPlayer].authenticated)
{
//do some stuff
}
})];
}
else
{
[localPlayer authenticateWithCompletionHandler:^(NSError *error){
if(localPlayer.isAuthenticated)
{
//Peform Additionl Tasks for the authenticated player.
}
}];
}
}
}
...
Since I've built the game using CCLayers instead of UIViewControllers, what alternatives do I have? Am I correct in assuming that CCLayers don't call use supportedInterfaceOrientations or shouldAutorotate?
Or am I supposed be changing this code somehow to fix the problem:
// Create a Navigation Controller with the Director
navController_ = [[UINavigationController alloc] initWithRootViewController:director_];
navController_.navigationBarHidden = YES;
This frustrated me for awhile too. After digging around for awhile on the 'Net I found a couple of sources and some worked with iOS 6, some with iOS5, but I had to make some modifications so that it worked the way I wanted on both iOS5 and iOS6. This is the code I am using, it works on my iPhone using 5.1 and 6. Note that the Game Center login still comes up in portrait orientation, there doesn't appear to be anything you can do about that. But the rest of the game will remain in landscape mode.
enable portrait mode as a supported orientation in your build settings (info.plist).
Create a new subclass of UINavigationController. Name this class whatever makes sense to you.
In your AppDelegate, include your new custom UINavigationController header file.
In your App Delegate, comment out the original call and instead call your custom class.
That should do the trick. Here is the code from my custom class:
#import <UIKit/UIKit.h>
#interface CustomNavigationViewController : UINavigationController
-(UIInterfaceOrientation) getCurrentOrientation;
#end
And the implementation file:
#import "CustomNavigationViewController.h"
#interface CustomNavigationViewController ()
#end
#implementation CustomNavigationViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
// This is required to allow GameCenter to login in portrait mode, but only allow landscape mode for the rest of the game play/
// Arrrgg!
-(BOOL) shouldAutorotate {
return YES;
}
-(NSUInteger) supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
-(UIInterfaceOrientation) preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationLandscapeRight; // or left if you prefer
}
-(NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
return UIInterfaceOrientationMaskLandscape;
else {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
}
-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return [[UIDevice currentDevice] orientation] != UIInterfaceOrientationPortrait;
}
-(UIInterfaceOrientation) getCurrentOrientation {
return [[UIDevice currentDevice] orientation];
}
#end
Note that last method getCurrentOrientation isn't required I just put that in there in case I wanted to determine what the current orientation is.
The custom class is called in AppDelegate.m like this: (comment out the original code)
navController = [[CustomNavigationViewController alloc] initWithRootViewController:director];
window.rootViewController = navController;
navController.navigationBarHidden = YES;
[window makeKeyAndVisible];
Hope this helps.
I'm not experienced in programming.
I was trying to do an easy iOS app (just to try some tutorials) that works as a "sendmail"
Easy interface with just 1 button that when pressed, it opens the MFMailComposeViewController window.
That's the code.
ViewController.h
#import <UIKit/UIKit.h>
#import <MessageUI/MFMailComposeViewController.h>
#import <MessageUI/MessageUI.h>
#interface ViewController : UIViewController <MFMailComposeViewControllerDelegate>
-(IBAction)showPicker:(id)sender;
#end
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
-(IBAction)showPicker:(id)sender
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
NSArray *toRecipients = [NSArray arrayWithObject:#"example#example.com"];
[picker setToRecipients:toRecipients];
[picker setSubject:#"TEST SUBJECT"];
[self presentViewController:picker animated:YES completion:nil];
}
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
On the iPhone and iPad simulator it works like a charm.
But when testing it on the device it crashes giving signal SIGABRT and showing as evidence that part of main.m:
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
with a "Thread 1 - Signal SIGABRT" near.
Any tip?
Thanks to everyone in advance.
Two things to try:
Clean the files <SHIFT+CMD+K>
Uninstall the file from your device and try with the cleaned one
Right at the beginning of showPicker: add this :
if [MFMailComposeViewController canSendMail]
{
// Your code
}
else
NSLog(#"No mail account configured on device or not supported");
I am trying to do something similar to what was requested in this question:
Playing audio with controls in iOS
I am using Storyboards with XCode 4.2. On my initial view page, I just have buttons that call other views, and no sounds are played there. These other views contain a UINavigationController with a BarButtonItem to allow you to go back. Other view pages will have buttons that allow one to play a sound. Each sound has its own play button, and there are resume, pause and stop buttons.
All sounds play fine, but if I hit the back button to the main page, the sound keeps playing. The desired behavior is for the sound to stop when navigating back to the main page via the back button.
Before storyboards, I could easily code a back button to stop the audio, but storyboards appear not that simple. It appears that I have to implement the method prepareForSegue. Okay, I can set the Segue identifier can be set in the Attributes Inspector, and referring back to the earlier post, I will use showPlayer.
But I was thinking I could code the prepareForSegue in one of my sound views, as seen in this cool example:
http://www.scott-sherwood.com/?p=219
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([[segue identifier] isEqualToString:#"showPlayer"]){
SoundPageController *theAudio = (SoundPageController *)[segue ViewController];
theAudio.delegate = self;
}
}
In the main page ViewController.m, I tried adding:
#property (strong, nonatomic) AVAudioPlayer *theAudio;
And I tried adding something like:
- (void)viewDidLoad {
[super viewDidLoad];
// this is the important part: if we already have something playing, stop it!
if (audioPlayer != nil)
{
[audioPlayer stop];
}
// everything else should happen as normal.
audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
I wasn't able to get this to work, so I reverted the changes back to original. I will put my simplified code below, and if you have suggestions how to do it right, please let me know!
ViewController.h:
#interface ViewController : UIViewController {
}
ViewController.m (pretty much default):
#import "ViewController.h"
#import "AppDelegate.h"
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
SoundPage1.h:
#import
#import <AVFoundation/AVAudioPlayer.h>
#interface occupy : UIViewController <AVAudioPlayerDelegate> {
AVAudioPlayer* theAudio;
}
//-(IBAction)PressBack:(id)sender; now the back button is linked up through storyboard
-(IBAction)pushButton1;
-(IBAction)pushButton2;
-(IBAction)play;
-(IBAction)stop;
-(IBAction)pause;
#end
SoundPage1.m
#import "SoundPage1.h"
#import "AppDelegate.h"
#import "ViewController.h"
#implementation SoundPage1
-(IBAction)pushButton {
NSString *path = [[NSBundle mainBundle] pathForResource:#"sound1" ofType:#"mp3"];
if(theAudio)[theAudio release];
theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate = self;
theAudio.volume = 1.0;
[theAudio play];
}
-(IBAction)pushButton2 {
NSString *path = [[NSBundle mainBundle] pathForResource:#"sound2" ofType:#"mp3"];
if(theAudio)[theAudio release];
theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate = self;
theAudio.volume = 1.0;
[theAudio play];
}
// Old code from XCode 3.x when creating a back button that could stop the audio was easy
//-(IBAction)PressBack:(id)sender{
// [theAudio stop];
// ViewController* myappname = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
// [self.navigationController pushViewController:myappname animated:NO];
// }
- (void)viewDidLoad
{
[super viewDidLoad];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
Add in the code for play, stop and pause for the buttons.
I tried to format this, sorry in advance if it is hard to read.
Thanks for any suggestions!

You should stop the AVAudioPlayer in viewWillDisappear.
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
if(theAudio && theAudio.isPlaying) {
[theAudio stop];
}
}
ViewDidUnload is only called by the program when the device is reaching the end of memory capacity, not when you change views. Only just found this out myself this week, while struggling with the same problem.
Hope that clears things up.
My app supports only Landscape. I've added an MPMoviePlayerController to the view of my view controller.
When I press full screen button, it works fine and it will rotate in Landscape only for iOS versions prior to iOS 5. However, in iOS 5.0+, it also supports portrait (only when I enter into full screen mode).
How can I prevent portrait support in iOS 5.0 and above?
Try subclassing MPMoviePlayerViewController and overriding the shouldAutorotatoToInterfaceOrientation method to only support landscape modes:
-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
if((toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight))
{
return true;
}
else
{
return false;
}
}
I resolved this problem thus: create custom navigation controller what support 2 orientation:
UIInterfaceOrientationLandscapeLeft && UIInterfaceOrientationLandscapeRight
More details:
1. Create custom navigation controller
CustomNavigationController.h file
#import <UIKit/UIKit.h>
#interface CustomNavigationController : UINavigationController
-(CustomNavigationController*)initWithRootViewController:(UIViewController *)rootViewController;
#end
CustomNavigationController.m file
#implementation IORNavigationController
-(CustomNavigationController*)initWithRootViewController:(UIViewController *)rootViewController
{
self = [super initWithRootViewController:rootViewController];
if (self)
{
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
#end
2.In Appdelegate add self navigation controller
Appdelegate.h
#property (nonatomic, retain) CustomNavigationController* navigationController;
Appdelegate.m
self.navigationController = [[[CustomNavigationController alloc] initWithRootViewController:start] autorelease];
self.navigationController.view.autoresizesSubviews = YES;
window.rootViewController = self.navigationController;
[self.navigationController setNavigationBarHidden:YES];
And now you have app with two orientation and video in landscape orientation.
