带摄像头源的UIImagePickerController允许编辑是：视频修剪不起作用 [英] UIImagePickerController with camera source with allows editing yes : video trimming doesn't work

问题描述

我正在使用 UIImagePickerController 来录制一个视频，其sourceType设置为 UIImagePickerControllerSourceTypeCamera 。

I am using UIImagePickerController to record a video with the sourceType set to UIImagePickerControllerSourceTypeCamera.

我已将 allowsEditing 设置为true。

I have set allowsEditing to true.

捕获视频后，我编辑了视频使用修剪界面并按使用，我只回到原始记录而不是修剪版本。我做错了什么？

After capturing video I edit the video using the trimming interface and press "Use", I only get back the original recording not the trimmed version. What am I doing wrong?

我使用的是iOS 5.

I am using iOS 5.

-(void)shootvideo {
    imagePicker = [[UIImagePickerController alloc] init];
    [imagePicker.view addSubview:test];
    [imagePicker.view addSubview:test2];

    imagePicker.delegate = self;
    imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;

    imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
    imagePicker.showsCameraControls = YES;
    imagePicker.navigationBarHidden = NO;
    imagePicker.toolbarHidden = NO;
    imagePicker.wantsFullScreenLayout = YES;
    imagePicker.allowsEditing=YES;

    [self presentModalViewController:imagePicker animated:YES];
}


-(void) imagePickerController: (UIImagePickerController *) picker
didFinishPickingMediaWithInfo: (NSDictionary *) info 
{
    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];


    if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0)
        == kCFCompareEqualTo) 
    {

        NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

        //NSLog(@"%@",moviePath);

        if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
            UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);
        }
    }

    [self dismissModalViewControllerAnimated:YES];  
}

我想根据我的应用程序使用裁剪后的视频进行进一步处理。

I want to use that trimmed video for further processing according to my application.

我哪里出错？

还有其他办法可以完成这项任务吗？

Is there any other way to achieve this task?

推荐答案

你需要从 - （void）imagePickerController中获取信息[UIImagePickerControllerEditedImage] :( UIImagePickerController *）picker didFinishPickingMediaWithInfo：（NSDictionary *）info

you need to grab the info[UIImagePickerControllerEditedImage] from the - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

我相信。
