How do I get a photo from the phone gallery? - iphone

Question

I have a huge problem as am trying to open image picker but don't know why my app crashes at this line
[self presentViewController:(UIViewController *)imgpkrController animated:YES completion:nil];
I have used this this code in many application and code is working fine but in my current apps this code giving exception of preferred interface orientation.
The code which is used :
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
if (cameraAvailable == TRUE) {
if (buttonIndex == 0) {
imgpkrController.delegate = self;
imgpkrController.allowsEditing = YES;
imgpkrController.sourceType = UIImagePickerControllerSourceTypeCamera;
//[self presentModalViewController:(UIViewController *)imgpkrController animated:YES];
[self presentViewController:(UIViewController *)imgpkrController animated:YES completion:nil];
}
else if(buttonIndex == 1){
imgpkrController.delegate = self;
imgpkrController.allowsEditing = YES;
imgpkrController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
//[self presentModalViewController:(UIViewController *)imgpkrController animated:YES];
[self presentViewController:(UIViewController *)imgpkrController animated:YES completion:nil];
}
}
if (buttonIndex == 0) {
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
imgpkrController.delegate = self;
imgpkrController.allowsEditing = YES;
imgpkrController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
//imgpkrController.modalPresentationStyle=UIModalPresentationFullScreen;
//[self presentModalViewController:imgpkrController animated:YES];
[self presentViewController:(UIViewController *)imgpkrController animated:YES completion:nil];
//[self presentViewController:imgpkrController animated:YES completion:nil];
}
else{
NSLog(#"ipad photo");
imgpkrController.delegate = self;
popoverController = [[UIPopoverController alloc] initWithContentViewController:imgpkrController];
[popoverController presentPopoverFromRect:CGRectMake(260.0, 0.0, 400.0, 570.0) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
else{
if (buttonIndex == 0) {
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
imgpkrController.delegate = self;
imgpkrController.allowsEditing = YES;
imgpkrController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
//[self presentModalViewController:(UIViewController *)imgpkrController animated:YES];
[self presentViewController:(UIViewController *)imgpkrController animated:YES completion:nil];
}else{
NSLog(#"ipad photo");
imgpkrController.delegate = self;
popoverController = [[UIPopoverController alloc] initWithContentViewController:imgpkrController];
[popoverController presentPopoverFromRect:CGRectMake(260.0, 0.0, 400.0, 570.0) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
}
}
Code crashes on this line
[self presentViewController:(UIViewController *)imgpkrController animated:YES completion:nil];
with exception:

Answer 1

Not sure what's causing your error message as it seems to be related to the device orientation but I managed to get this working with the following code:
- (IBAction)attachPhotosClicked:(id)sender
{
if (![UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear])
{
_imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[_popoverController presentPopoverFromRect:self.attachButton.frame inView:self.view
permittedArrowDirections:(UIPopoverArrowDirectionLeft)
animated:YES];
return;
}
else
{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Choose a source"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"Camera", #"Photo Library", nil];
[actionSheet showFromRect:self.attachButton.frame inView:self.view animated:YES];
}
}

Answer 2

- (IBAction)selectPhoto:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}

Answer 3

You will find this issue in iOS 6.0. have a look at the following link,
UIPopoverController orientation crash in iOS 6
It should be fixed in later versions.

Answer 4

I think your problem is due to an iOs version problem. The interfaceOrientation protocol is changed in iOs 6.
I think this link could help you.
