UIImagePickerController doesn't delete temp video capture file from /tmp/capture - ios

Question

My app is recording videos using a UIImagePickerController and saves it to the camera roll just fine but my problem is that the recorded video is also being saved in the /tmp/capture directory and doesn't get deleted. My app slowly accumulates a long list of videos stored in the tmp/capture directory using lots of unnecessary data because of this. I am using ARC and iOS7 SDK.
-(BOOL)startCameraControllerFromViewController:(UIViewController*)controller usingDelegate:(id )delegate forType: (int)type
{
if (([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil)
|| (controller == nil)) {
return NO;
}
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
if(type == IMAGE )
cameraUI.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeImage, nil];
if(type == VIDEO)
{
cameraUI.videoMaximumDuration = 60.0f;
cameraUI.videoQuality = UIImagePickerControllerQualityType640x480;
cameraUI.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
}
cameraUI.allowsEditing = NO;
cameraUI.delegate = delegate;
[controller presentViewController: cameraUI animated: YES completion:nil];
return YES;
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
if(CFStringCompare ((__bridge_retained CFStringRef)mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo)//video
{
NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath))
UISaveVideoAtPathToSavedPhotosAlbum(moviePath, self,#selector(video:didFinishSavingWithError:contextInfo:), nil);
[self dismissViewControllerAnimated:NO completion:nil];
globalDel.videoPath = moviePath;
globalDel.videoToUpload = [NSData dataWithContentsOfFile:moviePath];
}
}
globalDel.videoPath is defined as: #property(nonatomic,retain)NSString *videoPath;
globalDel.videoToUpload is defined as: #property(nonatomic,retain)NSData *videoToUpload;
I set them to NULL once done with them.
I use a delegate file to keep those references for use between different navigation controllers.
Why is the app saving the file to the tmp folder each time and how do I stop it from doing that?
Thanks

You need to delete the directory containing the movie once your upload is finished (which will also delete the temp file):
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:globalDel.videoPath]) {
NSError *error;
// Attempt to delete the folder containing globalDel.videoPath
if ([fileManager removeItemAtPath:[globalDel.videoPath stringByDeletingLastPathComponent] error:&error] != YES) {
NSLog(#"Unable to delete file: %#", [error localizedDescription]);
}
}
