UIImagePickerControllerDelegate not responding properly - iphone

Question

I'm using the UIImagePickerController in iOS 4.2.1 on an iPhone 3Gs. I've previously used the deprecated method
- (void)imagePickerController: didFinishPickingImage: editingInfo:
without a problem. I have another app using the new didFinishPickingMediaWithInfo API in another app, and the method is never getting called by the picker once media is chosen.
//MyViewController.h
#interface MyViewController : UIViewController < UIImagePickerControllerDelegate, UINavigationControllerDelegate>
//MyViewController.m
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
UIImagePickerController *picker = [[UIImagePickerController new] autorelease];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
picker.videoQuality = UIImagePickerControllerQualityTypeHigh;
picker.allowsEditing = NO;
[self presentModalViewController:picker animated:TRUE];
}
- (void)imagePickerController:(UIImagePickerController *)picker imagePickerController:didFinishPickingMediaWithInfo:(NSDictionary *)editingInfo{
//**NEVER CALLED**
}

Answer 1

you have
- (void)imagePickerController:(UIImagePickerController *)picker imagePickerController:didFinishPickingMediaWithInfo:(NSDictionary *)editingInfo
where you probably want
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

Answer 2

You have this:
- (void)imagePickerController:(UIImagePickerController *)picker imagePickerController:didFinishPickingMediaWithInfo:(NSDictionary *)editingInfo
Look like you repeated the 'imagePickerController:' part of that method.

Answer 3

Putting the picker in the autorelease pool may be your problem -- it probably doesn't stick around long enough to call its delegate. Retain it instead:
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
And then in the delegate you can release it:
[picker dismissModalViewControllerAnimated:YES];
[picker release];

Answer 4

It may be that this line:
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
is returning false. This happens if the user's photo library is empty; this would be true on the iPhone simulator, for example.
EDIT: As the other examples show, you've also mistyped the delegate method. It should be:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

This is program that i have used to upload video to webservice through iOS 4.2 on 3g
-(void)uploadeVideoClicked{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
ipc.allowsEditing=NO;
ipc.videoQuality = UIImagePickerControllerQualityTypeMedium;
ipc.mediaTypes =[UIImagePickerController availableMediaTypesForSourceType:ipc.sourceType];
ipc.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
ipc.delegate = self;
[self presentModalViewController:ipc animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSMutableDictionary *infoDict = [[NSMutableDictionary alloc]init];
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:#"public.image"]){
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"" message:#"You Select a image Please select Movie" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[myAlertView show];
[myAlertView release];
} else if ([mediaType isEqualToString:#"public.movie"]){
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
mAppDelegate.uploadType = #"Video";
NSData *webData = [NSData dataWithContentsOfURL:videoURL];
[infoDict setValue:webData forKey:#"VideoUrl"];
[infoDict setValue:[[mAppDelegate.userInfoArray objectAtIndex:1]valueForKey:#"user_id"] forKey:#"user_id"];
//Call webService to upload video ;
}
[picker dismissModalViewControllerAnimated:YES];
[infoDict release];
}
