添加

#import <MediaPlayer/MediaPlayer.h>
#import <MobileCoreServices/UTCoreTypes.h>

and use following delegate method of UIImagePickerViewController

然后使用UIImagePickerViewController的委托方法。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
   if ([[info objectForKey:UIImagePickerControllerMediaType ] isEqualToString:@"public.movie"])
   {
     MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[info objectForKey:UIImagePickerControllerMediaURL];];
        UIImage  *thumbnail = [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame];
        [player stop];
        player = nil;

     // Here your got UIImage name is 'thumbnail'
   }
}

You can get image (thumbnail) from video.

你可以从视频中得到图像(缩略图)。
