Question

我建立的应用程序称为“KiKi”，它的第一页是“StartView”。应用程序将运行启动视图并检查用户是否已登录。之后，它会将用户重定向到正确的页面。

该应用程序在我的iPhone 6（真实的）上正常运行。但它在启动时总是启动缓慢。启动大约需要2-3秒。（我的其他应用程序只需要大约1秒钟即可启动）。

最近，我已将该应用程序提交到iTunes Connect，但它仍然停留在“添加新版本”页面。我无法选择任何构建版本，只显示“（处理）”。我已经等了几天但没有改变。我相信这是因为app中的错误。

路径：“StartView” - ＆gt; “LoginView”（如果用户已注销）或“LoginVerificationView”（如果用户已登录）

您的帖子中有许多事项需要注意

警告：正在主线程上执行长时间运行的操作。打破warnBlockingOperationOnMainThread（）进行调试。

这是来自解析的警告，这意味着您必须在此方法中放置断点以实际找出原因。保持断点后，只需查看堆栈跟踪即可找到该方法。您可能希望在后台执行一些解析活动。

一些解析方法用于在后台执行。而不是

[yourParseObject save] 您可以使用 [yourParseObject saveInBackground]

这也可能是您的应用需要时间启动的原因之一。

我无法选择任何构建版本，只显示“（处理）”。我已经等了几天但没有任何改变。

如果您的应用处于处理状态，原因可能是任何原因。最好的选择是通过参考资料和帮助部分的iTunesconnect联系我们页面告诉Apple你的情况。

与此同时，您也可以尝试本post

中提到的内容

其他建议：

不鼓励在分离的视图控制器上显示视图控制器。开始/结束的不平衡呼叫   外观过渡为。

原因是你在viewWillAppear上展示了一个viewcontroller。你不应该这样做。您应该直接显示LoginView。而不是StarView。

希望这有帮助。
