UIImagePickerController *videoPicker = [[UIImagePickerController alloc] init];
videoPicker.delegate = self;
videoPicker.modalPresentationStyle = UIModalPresentationCurrentContext;
videoPicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
videoPicker.mediaTypes = @[(NSString*)kUTTypeMovie, (NSString*)kUTTypeAVIMovie, (NSString*)kUTTypeVideo, (NSString*)kUTTypeMPEG4];
videoPicker.videoQuality = UIImagePickerControllerQualityTypeHigh;
[self presentViewController:videoPicker animated:YES completion:nil];
but it only show videos from photos part not all video in camera roll. 但它只显示照片中的视频,而不是所有视频中的视频。 I want to pick all video from Camera roll.
我想从相机胶卷中选择所有视频。 Please help me by giving some clue or code.
请通过提供一些线索或代码来帮助我。 Thanks in advance!

Here is a compilation and cleanup of the answer above plus a few more details. 以下是对上述答案的汇编和清理以及更多细节。
(0) Ensure you have these two includes. (0)确保你有这两个包含。
#import <UIKit/UIKit.h>
#import <MobileCoreServices/MobileCoreServices.h> // needed for video types
(1) Add two delegates to your .h file: UINavigationControllerDelegate and UIImagePickerControllerDelegate. (1)在你的.h文件中添加两个代理:UINavigationControllerDelegate和UIImagePickerControllerDelegate。 For us, it looked like this:
对我们来说,它看起来像这样:
@interface ATHViewController () <UITabBarDelegate, UINavigationControllerDelegate,UIImagePickerControllerDelegate>
(2) Present the user with choice of videos from their library. (2)向用户呈现其库中的视频选择。 Add this code to your .m file somewhere.
将此代码添加到某处的.m文件中。
// 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. (3)处理选择器的响应。 Add this code to your delegate class.
将此代码添加到您的委托类。
- (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. (4)当用户取消选择任何东西时处理。
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Please use the following code to select video from iOS gallery 请使用以下代码从iOS库中选择视频
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];
