iPhone4的示例视频捕获代码

Question

嗨，有谁可以帮助我为iPhone4的视频捕获代码。

我用下面的代码，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与

cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo

阅读UIImagePickerController Class Reference文档了解更多信息。
