UIImagePickerControllerDelegate not responding properly

Question

I am using UIImagePickerController in iOS 4.2.1 on iPhone 3Gs. I used an obsolete method earlier

- (void)imagePickerController: didFinishPickingImage: editingInfo:

no problem. I have another application using the new didFinishPickingMediaWithInfo API in another application, and this method will never be called by the collector after selecting the media.

//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 do you probably want

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

Answer 2

Perhaps this line:

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {

returns false. This happens if the user's photo library is empty; for example, this would be true on the iPhone simulator.

, webservice iOS 4.2 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"];
