Question

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。现在在左侧的屏幕显示重录按钮下方和右侧的使用按钮。这是我的问题开始，如果我按下使用按钮，如何将视频不同名称保存在特定文件夹中？我如何从该特定文件夹中访问该视频？

请提供示例代码以解决此问题。

提前致谢，

您必须实现以成为UIImagePickerController对象的委托并实现imagePickerController:didFinishPickingMediaWithInfo:，如下所示 -

- (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];
}

如何从iPhone应用程序捕获视频？
