Interface Builder 文件中的未知 class OTKTextChatView ios

Question

我在我的 iOS 应用程序中集成了用于聊天功能的 TokBox。

我用过这个link

这是我的代码

- (void)sessionDidConnect:(OTSession*)session {

    // When we've connected to the session, we can create the chat component.

    // crash on following line

    _textChat = [[OTKTextChatComponent alloc] init];

    _textChat.delegate = self;

    [_textChat setMaxLength:1050];
    [_textChat setSenderId:session.connection.connectionId alias:session.connection.data];

    CGRect r = self.view.bounds;
    r.origin.y += 20;
    r.size.height -= 20;
    [_textChat.view setFrame:r];
    [self.view addSubview:_textChat.view];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];

    // fade in
    _textChat.view.alpha = 0;

    [UIView animateWithDuration:0.5 animations:^() {
        //_connectingLabel.alpha = 0;
        _textChat.view.alpha = 1;
    }];

}

此演示运行良好。但是当我试图将它集成到我的项目中时。它给出以下错误：

Unknown class OTKTextChatView in Interface Builder file.
 *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIView 0x7f8c43835fa0> setValue:forUndefinedKey:]: 

this class is not key value coding-compliant for the key countLabel.'
    *** First throw call stack:

请帮帮我

Answer 1

这是因为 OTKTextChatView class 在 xib 加载之前没有加载（因为它在外部库中）。通常我们设置 -all_load，但在文档中它说

Do not use the -all_load linker flag. Instead, use the -force_load linker flag to load specific libraries that require it.

如果这没有帮助，请尝试在您的应用程序中添加以下代码完成启动方法

[OTKTextChatView class];

这将强制加载 OTKTextChatView class.

这对你有帮助。

根据 Maulik 的建议：- 添加这三个库 OTKTextChatLibrary,OTKTextChatBundle & OTKTextChatBundle.bundle..如果你不添加这个就会出现这种类型的错误
