Question

我已经读过这个错误，但我发现的是与XIB和连接器有关。

我看过了，但是我找不到连接器的任何问题......但是当我到达这行代码时，我仍然会收到此错误：

NSMutableString pageData = [pacUtils requestErrorHistory:pac_ipAddr:pacPort];

这是在类“pacUtils”中调用一个函数。我可以单步执行方法“requestErrorHistory”，它返回到这行代码之前没有任何问题。

此外，它在模拟器中运行良好......

这是我的日志中唯一的错误，但它也是最后一个版本（运行正常）因为我实际上找不到对此png文件的任何引用。即使我在文本编辑器中打开XIB。

我在Xcode 9.1下运行。

非常感谢任何帮助。
