Question

在我们使用SignalR-ObjC的iOS应用中，该应用的连接正常。因为iOS应用程序在后台没有响应，无法接收信号器消息。所以我们有以下实施：

SRHubConnection *connection = [[SRHubConnection alloc] initWithURLString:url useDefault:NO]

应用程序转到后台：[连接停止];停止连接。
App来到前景：[连接开始];创建一个新的连接对象并启动它。

但是如果我们连续3到4次在背景和前景之间切换，会使连接不稳定并且不再连接并抛出跟随错误。

问题： 有没有办法阻止SRHubConnection进入这种不稳定状态并启动新连接而没有错误？

Answer 1

确保您没有在连接对象上多次调用start或stop。多次调用它们会导致连接处于不稳定状态。

停止＆amp;多次启动SignalR-Objc SRHubConnection会使连接不稳定
