如何從UIImagePickerController中選擇一個視頻並播放它？

Question

目前我使用下面的代碼來獲取NSURL。但是當我拿到NSURL後，我該怎麼玩呢？

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
     { 
      NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; 
      if ([mediaType isEqualToString:@"public.image"]){ 
       // UIImage *selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage]; 
       UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; 
       NSLog(@"found an image"); 
      } 
      else if ([mediaType isEqualToString:@"public.movie"]){ 
       NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL]; 
       NSLog([videoURL absoluteString]); 
       NSLog(@"found a video");  
      } 
      [picker dismissModalViewControllerAnimated:YES]; 
     }

- (void)selectVideoFromLibrary 
{ 
    UIImagePickerController *imagePicker = 
     [[UIImagePickerController alloc] init]; 
     imagePicker.delegate = self; 
     imagePicker.sourceType = 
     UIImagePickerControllerSourceTypeSavedPhotosAlbum; 
     imagePicker.mediaTypes = [NSArray arrayWithObjects: 
            (NSString *) kUTTypeMovie, 
            nil]; 
     imagePicker.allowsEditing = NO; 
     [self presentViewController:imagePicker animated:YES completion:nil]; 

} 

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    NSURL *movieURL = (NSURL*)[info objectForKey:UIImagePickerControllerMediaURL]; 
    MPMoviePlayerController *movieplayer =[[MPMoviePlayerController alloc] initWithContentURL: url];  
    [[movieplayer view] setFrame: [self.view bounds]]; 
    [self.view addSubview: [movieplayer view]]; 
    [movieplayer play]; 
} 

Answer 2

網址是你的視頻地址

MPMoviePlayerController *plyr =[[MPMoviePlayerController alloc] initWithContentURL: url];  
[[plyr view] setFrame: [self.view bounds]]; 
[self.view addSubview: [plyr view]]; 
[plyr play];
