iPhone4的示例视频捕获代码

Question

任何人都可以帮我解决iPhone4的视频捕获代码问题。

我正在使用以下代码，但它不起作用：

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
NSArray *arraySourceTypes =[UIImagePickerController availableMediaTypesForSourceType:imagePicker.sourceType];  

if ([arraySourceTypes containsObject:(NSString *)kUTTypeMovie]){
    imagePicker.mediaTypes =  [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
    imagePicker.cameraDevice=UIImagePickerControllerCameraDeviceRear;
    imagePicker.cameraCaptureMode=UIImagePickerControllerCameraCaptureModeVideo;
    imagePicker.videoQuality=UIImagePickerControllerQualityTypeHigh;
    imagePicker.delegate = self;
    [self presentModalViewController:imagePicker animated:YES];   
    [imagePicker release];       
}
else
    [imagePicker release];

Answer 1

将UIImagePickerController与

一起使用

cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo
