ios - 测试时我的 iPhone 上的应用程序启动缓慢

Question

我构建的应用程序称为“KiKi”，它的第一页是“StartView”。该应用程序将运行开始 View 并检查用户是否登录。之后，它将用户重定向到正确的页面。

该应用程序在我的 iPhone 6(真机)上运行良好。但启动时总是启动缓慢。启动大约需要 2-3 秒。 (我的其他应用程序启动只需要大约 1 秒)。

最近，我已将应用程序提交到 iTunes Connect，但它卡在“添加新构建版本”页面。我无法选择任何构建版本，它只显示“(处理)”。我已经等了几天了，但什么都没有改变。我认为这是因为应用程序中的错误。

路径:“StartView”-->“LoginView”(如果用户注销)或“LoginVerificationView”(如果用户登录)

Answer 1

你的帖子有很多地方需要注意

1. Warning: A long-running operation is being executed on the main thread. Break on warnBlockingOperationOnMainThread() to debug.

这是来自 parse 的警告，意味着您必须在此方法中放置一个断点才能真正找出原因。保留断点后，只需查看堆栈跟踪即可找到方法。您可能想在后台执行一些解析事件。

一些解析方法曾经在后台执行。喜欢而不是

[你的 ParseObject 保存]您可以使用 [yourParseObject saveInBackground]

这也可能是您的应用启动时间过长的原因之一。

2. I can't select any of the build version and it just displaying "(Processing)". I have waited for a few days but nothing changed.

如果您的应用处于处理状态，原因可能是任何原因。最好的选择是您通过资源和帮助部分中的 iTunesconnect 联系我们页面将您的情况告诉 Apple。

与此同时，您还可以尝试此 post 中提到的内容

补充建议:

3. Presenting view controllers on detached view controllers is discouraged . Unbalanced calls to begin/end appearance transitions for .

这样做的原因是您在 viewWillAppear 上呈现一个 View Controller 。你不应该那样做。您应该直接显示 LoginView 而不是 StarView。

希望这对您有所帮助。
