Iphone UIImagePickerController带摄像头源，允许编辑是：视频剪辑不'；行不通

我正在使用

UIImagePickerController

录制源类型设置为

UIImagePickerControllerSourceTypeCamera

的视频

我已将

allowsdediting

设置为true

捕获视频后，我使用修剪界面编辑视频，然后按“使用”，我只恢复原始录制，而不是修剪版本。我做错了什么

我使用的是iOS5

-(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经过修剪的视频进行进一步处理

我错在哪里

是否有其他方法来完成此任务？

允许编辑：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

@属性（非原子）布尔允许编辑

讨论 如果您允许用户编辑静止图像或电影，则学员可能会收到一本包含所做编辑信息的词典。委托的协议如中所述

我认为这会很有帮助。

您需要从-（void）imagePickerController:（UIImagePickerController*）picker完成PickingMediaWithInfo:（NSDictionary*）信息中获取信息[UIImagePickerController reditedImage]

我相信
