Question

我的应用中有一个ImageView，用户可以录制视频或从相机胶卷加载。如果我想在UIImageView中播放视频，我需要做什么。

她是代码：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    [picker dismissViewControllerAnimated:YES completion:nil];

    NSString *mediaType = info[UIImagePickerControllerMediaType];
    if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]) // Media is a video
    {
        NSURL* videoUrl = info[UIImagePickerControllerMediaURL];
        _videoUrl = [[NSURL alloc] initWithString:[videoUrl absoluteString]];
        [self loadVideo:_videoUrl];


    }

}

- (void)loadVideo:(NSURL*)url
{

    AVURLAsset *asset1 = [[AVURLAsset alloc] initWithURL:url options:nil];
    AVAssetImageGenerator *generate1 = [[AVAssetImageGenerator alloc] initWithAsset:asset1];
    generate1.appliesPreferredTrackTransform = YES;
    NSError *err = NULL;
    CMTime time = CMTimeMake(1, 2);
    CGImageRef oneRef = [generate1 copyCGImageAtTime:time actualTime:NULL error:&err];
    UIImage *one = [[UIImage alloc] initWithCGImage:oneRef];
    [_imageView setImage:one];
    _imageView.contentMode = UIViewContentModeScaleAspectFit;


}

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

我正在使用以下代码播放视频，但它正在全屏播放视频。

moviePlayer =  [[MPMoviePlayerController alloc]
                initWithContentURL:_videoUrl];


moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];

我需要播放视频，但在UIImageView中。有可能吗？

你的最终代码应该是这样的。你忘了添加框架

moviePlayer =  [[MPMoviePlayerController alloc]
                initWithContentURL:_videoUrl];


moviePlayer.view.frame = _yourImageView.frame;
moviePlayer.scalingMode = MPMovieScalingModeAspectFill;

moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];

使用Objective c播放视频
