iOS Camera not opening - ios

Question

I created an app a couple of years ago and had it working no problem at all. I've been asked to resurrect it and have stumbled apron a problem. When selecting a button to open up the camera and/or photo library it comes up with this message when choosing either option:
Warning: Attempt to present <UIImagePickerController: 0x100a13400> on :<ViewController: 0x100843a00> which is already presenting <UIAlertController:0x1001e8d40>`
Im wondering has there been changes between iOS's that i need to amend my code because of? Here is what I currently have:
- (IBAction)pickImage {
AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
if(status == AVAuthorizationStatusAuthorized) { // authorized
}
else if(status == AVAuthorizationStatusDenied){ // denied
}
else if(status == AVAuthorizationStatusRestricted){ // restricted
}
else if(status == AVAuthorizationStatusNotDetermined){ // not determined
[AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
if(granted){ // Access has been granted ..do something
} else { // Access denied ..do something
}
}];
}
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Pick Image"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"from Camera", #"from Library", nil] ;
[actionSheet showInView:self.view];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePickerController setDelegate:self];
[self presentModalViewController:imagePickerController animated:YES];
} else {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil
message:#"Your device has no camera."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
}
else if (buttonIndex == 1) {
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[imagePickerController setDelegate:self];
[self presentModalViewController:imagePickerController animated:YES];
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[imageView setImage:[info objectForKey:UIImagePickerControllerOriginalImage]];
[self dismissModalViewControllerAnimated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissModalViewControllerAnimated:YES];
}
Many Thanks for your help.

Not able to replicate that error message with that code, however, you can try replacing your UIActionSheet and UIAlertView with a UIAlertController.
Both of these are deprecated as of iOS 8.0, and have been replaced with the UIAlertController.
https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIAlertController_class/
You can set the preferred style attribute to "UIAlertControllerStyleAlert" or "UIAlertControllerStyleActionSheet".
