iphone - iPhone4 的示例视频捕获代码

Question

大家好，谁能帮我编写 iPhone4 的视频捕获代码。

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

使用 UIImagePickerController

cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo

阅读UIImagePickerController Class Reference文档以获取更多详细信息。
