我可以使用AVFoundation或UIImagePickerController录制视频.但我无法将视频从一个特定的秒钟修剪到另一个特定的持续时间/时间.谁能帮我.

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？

    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 …
