感谢大家回复我发布的问题。

我遇到了一个问题，即在 iPhone 中捕捉视频时，我不知道如何存储我用 iPhone 捕捉视频的时间段（持续时间）。任何人都可以解决我的问题。

我正在使用以下代码进行捕获。

-(void) RecordVideoWithCamera
{
    printf("\n Hai  I am in record vedio with camera  -============");
    [self startCameraPickerFromViewController:self usingDelegate:self];
}

- (BOOL)startCameraPickerFromViewController:(UIViewController*)controller usingDelegate:(id<UIImagePickerControllerDelegate>)delegateObject  
{  

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    {
        UIImagePickerController *picker = [[[UIImagePickerController alloc] init]autorelease];
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        picker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
        picker.delegate = self;
        picker.showsCameraControls=YES; 
        picker.allowsEditing = NO;
        UIView *overlayView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
        picker.cameraOverlayView = overlayView;
        [controller presentModalViewController:picker animated:YES];
    }
    return YES;  
}

谢谢你，马丹·莫汉。

我认为你应该检查 CMTime 结构。
