Here is how i use my IPC:
ipc = nil; // reset (camera may be running)
ipc = [[UIImagePickerController alloc] init];
[ipc setDelegate:self];
ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:ipc animated:YES completion:^(void){
[self cancelShoot];
}];
It works well on 3GS with iOS 6, also i have no issues on iOS 7 simulator. While testing on iOS 7 devices (iPod 5 gen, iPhone 4, iPhone 5) it always crashes.
Is there anything new to the latest OS that i should be aware of?
Is "ipc" a pointer? Given how you are setting sourceType it looks like it isn't..

Im trying to send an sms programmatically and in ios 6 its works perfect but in ios 7 its not working. Its open a white view with nothing inside and just stuck my app!
my code looks like this:
MFMessageComposeViewController *messageVC = [[MFMessageComposeViewController alloc] init];
[messageVC setMessageComposeDelegate:self];
if ([MFMessageComposeViewController canSendText]) {
NSString *smsString = [NSString stringWithFormat:#"bla bla bla"];
messageVC.body = smsString;
messageVC.recipients = #[userPhone];
messageVC.messageComposeDelegate = self;
[self presentViewController:messageVC animated:YES completion:nil];
}
please help!! ios7 driving me crazy!
Your code works fine, but the message "Text messaging is not available" is given on devices that are not capable to send messages. I tested on an iPad Mini and it's working fine.
I am still using iOS 5 SDK and Xcode 4.2 (Snow Leopard). I am adding Game Center to my game and while it passed authentication I get an ARC error whenever I try to show a leaderboard with this code (from Apple):
- (void) showLeaderboard: (NSString*) leaderboardID
{
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
if (leaderboardController != nil)
{
**leaderboardController.leaderboardDelegate = self;**
leaderboardController.timeScope = GKLeaderboardTimeScopeToday;
leaderboardController.category = leaderboardID;
[self presentViewController: leaderboardController animated: YES completion:nil];
}
}
I get this error:
Passing "ViewController *const__strong' to parameter of incompatible type 'id <GKLeaderboardViewControllerDelegate>"
Is there any other solution than using iOS 6 SDK on lion?
Thanks!
Ah,
Found a similar problem, using id(self) fixed it;

is there any way to check video camera capability available on iPhone?
Most of the camera related availability support is exposed through the UIImagePickerController. A bit tricker thing is detection of Video Camera. You can detect the presence of a video camera in a iOS device using the following method.
- (BOOL) isVideoCameraAvailable
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
NSArray *sourceTypes = [UIImagePickerController availableMediaTypesForSourceType:picker.sourceType];
[picker release];
if (![sourceTypes containsObject:(NSString *)kUTTypeMovie ]){
return NO;
}
return YES;
}
Found this code (based on UIDevice) which helped me with this issue:

Can I programmatically turn on the camera flash on a new iPhone 4 device, before taking a picture with -takePicture?
I'm developing a photo taking app for iOS 4 and want to power on the flash light before the user takes a picture, so they can see the effect of the flash in advance.
The problem seems to be that for the flash light to stay on, you'll need to set the torchMode on and this is only possible in 'video mode' (UIImagePickerControllerCameraCaptureModeVideo), while you can only ask the UIImagePickerController to takePicture when it is on 'photo mode' (UIImagePickerControllerCameraCaptureModePhoto).
So, the following works, but only shows the flash light when taking a picture:
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.navigationBarHidden = YES;
picker.toolbarHidden = YES;
picker.mediaTypes = [NSArray arrayWithObjects:#"public.image", nil];
picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
picker.cameraFlashMode = UIImagePickerControllerCameraFlashModeOn;
[self presentModalViewController:picker animated:YES];
And this also works (shows the torch the whole time), but then I cannot take a picture.
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.navigationBarHidden = YES;
picker.toolbarHidden = YES;
picker.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, nil];
picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
picker.cameraFlashMode = UIImagePickerControllerCameraFlashModeOn;
[self presentModalViewController:picker animated:YES];
When I try the toggleTorch code found here: Turn on torch/flash on iPhone there seems to not be any live video feed in the UIImagePickerController.
Are these UIImagePickerController and AVCaptureSession compatible with each other? or are you supposed to choose for either one or the other?
And does anybody know a workaround to get both the flash mode on (or torchMode) and to be able to takePicture?
Have a look at the WWDC 2010 sessions (specifically 409) where they go into functionality like the one you're looking for.
Essentially you need to move away from UIImagePickerController if you're looking to perform these custom camera functions and move towards AVFoundation classes.
HI,
I need to record video using iPhone. To do that i used UIImagePickerController. I have an iPhone 3G, with me. when i run my code to check if source type available it says device not supported. My OS is 3.2.1, where i am wrong, can some one tell me what i need to change.
Also is there some other way to record video. What i need to do is to get the video stream as it is recorded.
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
NSArray *sourceTypes =
[UIImagePickerController availableMediaTypesForSourceType:picker.sourceType];
if (![sourceTypes containsObject:(NSString *)kUTTypeVideo ]){
NSLog(#"device not supported");
return;
}
//picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeVideo];
picker.videoQuality = UIImagePickerControllerQualityTypeHigh;
[self presentModalViewController:picker animated:YES];
Thanks,
That is because the 3G isn't supported for video recording.
Lance is correct. The native UIImagePickerController does not work on iPhone 3G. If an app does do video recording on a 3G they are doing a hack like taking multiple photos in succession and manually encoding a video file using the individual images.
