iPhone4的示例視頻捕獲代碼

Question

嗨，有誰可以幫助我爲iPhone4的視頻捕獲代碼。

我用下面的代碼，但它不工作：

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

使用的UIImagePickerController與

cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo

閱讀UIImagePickerController Class Reference文檔瞭解更多信息。
