Objective c - ios : How to pick video from Camera Roll?

Here is a compilation and cleanup of the answer above plus a few more details.

(0) Ensure you have these two includes.

#import <UIKit/UIKit.h>#import <MobileCoreServices/MobileCoreServices.h> // needed for video types

(1) Add two delegates to your .h file: UINavigationControllerDelegate and UIImagePickerControllerDelegate. For us, it looked like this:

@interface ATHViewController () <UITabBarDelegate, UINavigationControllerDelegate,UIImagePickerControllerDelegate>

(2) Present the user with choice of videos from their library. Add this code to your .m file somewhere.

    // Present videos from which to choose    UIImagePickerController *videoPicker = [[UIImagePickerController alloc] init];    videoPicker.delegate = self; // ensure you set the delegate so when a video is chosen the right method can be called    videoPicker.modalPresentationStyle = UIModalPresentationCurrentContext;    // This code ensures only videos are shown to the end user    videoPicker.mediaTypes = @[(NSString*)kUTTypeMovie, (NSString*)kUTTypeAVIMovie, (NSString*)kUTTypeVideo, (NSString*)kUTTypeMPEG4];    videoPicker.videoQuality = UIImagePickerControllerQualityTypeHigh;    [self presentViewController:videoPicker animated:YES completion:nil];

(3) Handle the responses from the picker. Add this code to your delegate class.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {    // This is the NSURL of the video object    NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];    NSLog(@"VideoURL = %@", videoURL);    [picker dismissViewControllerAnimated:YES completion:NULL];}

(4) Handle when the user cancels choosing anything.

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {    [picker dismissViewControllerAnimated:YES completion:NULL];}

Please use the following code to select video from iOS gallery

UIImagePickerController *videoPicker = [[UIImagePickerController alloc] init];videoPicker.delegate = self;videoPicker.modalPresentationStyle = UIModalPresentationCurrentContext;videoPicker.mediaTypes =[UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypePhotoLibrary];‌​videoPicker.mediaTypes = @[(NSString*)kUTTypeMovie, (NSString*)kUTTypeAVIMovie, (NSString*)kUTTypeVideo, (NSString*)kUTTypeMPEG4];videoPicker.videoQuality = UIImagePickerControllerQualityTypeHigh;[self presentViewController:videoPicker animated:YES completion:nil];
