带摄像头源的UIImagePickerController允许编辑是:视频修剪不起作用

Question

我UIImagePickerController用来录制sourceType设置为的视频UIImagePickerControllerSourceTypeCamera.

我已经设定allowsEditing为真.

在捕获视频后,我使用修剪界面编辑视频并按"使用",我只返回原始记录而不是修剪版本.我究竟做错了什么？

我正在使用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修剪过的视频进行进一步处理.

我哪里错了？

有没有其他方法可以完成这项任务？

Answer 1

allowedEditing：一个布尔值，指示是否允许用户编辑选定的静态图像或电影。

@property（非原子）BOOL 允许编辑

讨论 如果您允许用户编辑静态图像或电影，代理人可能会收到一本字典，其中包含有关所做编辑的信息。UIImagePickerControllerDelegate 协议参考中描述了委托的协议。

我认为这会有帮助。
