如何从iPhone应用程序捕捉视频？

Question

我按下录制按钮的同时打开视频模式。然后我可以捕捉视频。捕获后，视频记录必须停止。现在位于左侧的屏幕显示重拍按钮下方，并使用右侧的按钮。这里是我的问题开始，如果我按下使用按钮，如何将视频不同的名称保存在特定的文件夹中？我怎样才能访问该特定文件夹中的视频？

请给出与示例代码的想法来解决这个问题。

由于提前，

您将必须实现成为UIImagePickerController对象的委托，并实现imagePickerController:didFinishPickingMediaWithInfo:这样的 -

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
    // This is the URL where the movie is stored (in the tmp directory) 
    NSURL *movieURL = [info objectForKey:UIImagePickerControllerMediaURL]; 

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
    NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"movie.mov"]; // You will have to vary this. 
    NSURL *fileURL = [NSURL URLWithString:filePath]; 

    NSError *error; 
    if ([[NSFileManager defaultManager] moveItemAtURL:movieURL toURL:fileURL error:&error]) {  
     NSLog(@"Error copying: %@", [error localizedDescription]); 
    } 

    [self dismissModalViewControllerAnimated:YES]; 
}
