iOS 11 唯一崩溃问题 - 当我点击标签栏时应用程序崩溃

Question

当我仅从 hometabviewcontroller 点按特定选项卡栏时出现以下崩溃错误。这仅在 iOS 11 中发生。请帮助我解决此问题。

当我仅在 iOS 11 中点击 tabbar-4 时，此应用程序崩溃了。我不明白我的代码有什么问题。在 Hometabviewcontroller 或 accountscontroller 上，我没有得到任何与 refreshController 相关的代码。但是当我搜索整个代码库时，我得到了以下信息。

    - (void)refresh:(UIRefreshControl *)refreshControl
{
    [refreshControl endRefreshing];
}

以下是特定 tabview 控制器的 viewloads 代码。

    return self;
}

Answer 1

您可以跟踪unrecognized selector sent to instance 的来源。您的代码中的某些内容正在调用它。

在 hometabviewcontroller 或整个项目中搜索 refreshControl 并查看调用它的位置和内容，并确保它是您想要的。

如果这没有帮助，我们需要更多代码（最好是hometabviewcontroller）来帮助您。
