Ios 如何禁用VLCMediaPlayer错误警报视图？

我正在使用MobileVLCKit库中的VLCMediaPlayer类来制作音频流应用程序。我的问题是，当发生错误时（例如，错误的流url），它会自动提醒自己的错误消息。在我的例子中，我想禁用该警报消息并显示我自己的警报消息

---

我通过在VLC源代码中转到VLCLibrary.m并删除这一行来解决这个问题：

@"--extraintf=ios_dialog_provider"];

从defaultOptions调用

删除它，重新编译库，您将不会看到更多消息。

无需从源代码中删除此选项！ 只需按如下方式传递播放器选项：

NSArray *options = @[@"--extraintf="];
VLCMediaPlayer *player = [[VLCMediaPlayer alloc] initWithOptions:options];

使用MobileVLCKit的最新版本（MobileVLCKit prod 2.7.9），您可以在某些对象上实现VLCCustomDialogRendererProtocol 之后

...
@property (nonatomic, strong) VLCDialogProvider * dialogProvider;
....
        //dump information
        VLCLibrary * lib=[VLCLibrary sharedLibrary];

        //configure dialog provider
        self.dialogProvider=[[VLCDialogProvider alloc] initWithLibrary:lib customUI:YES];
        self.dialogProvider.customRenderer=self;

...

对话框提供程序的实现可以显示它喜欢的任何对话框，或者根本不显示任何对话框。 委托方法的“只记录但不显示”版本示例

谢谢！！也许您可以再次提供帮助：）如果发生委托错误，我如何捕获该错误？我尝试了

-（void）mediaPlayerStateChanged:（NSNotification*）加密

，但检索错误失败。。。谢谢我想请你喝杯啤酒
