初始化：
		- (void)registerAppKey:(NSString *)appKey appName:(NSString *)appName;
		
	集成客户聊天组件：
		- (WSKChatViewController *)chatViewController;
		
	自定义客户端聊天组件UI效果：
		- (WSKUIConfig *)customUIConfig;
		
	APNs推送：
		- (void)updateApnsToken:(NSData *)token;
		
	注销：
		- (void)logout:(WSKCompletionBlock)completion;

	设置用户信息：
		- (void)setUserInfo:(WSKUserVo *)userVo;

	设置调试模式获取更多的Log信息，发布应用时建议不开启，用于节省性能开销：
		- (void)setDebugMode;
