更新至IOS11和Xcode9后出现的问题！！“com.google.Maps.LabelingBehavior”，“TIC Read Status”

Question

我已经将手机和Xcode更新到最新版本，但是出现了很多警告。

第一个警告是2017-09-21 00:23:15.669466+0100 The Kallos[12068:1279021] TIC Read Status [1:0x0]: 1:57

关于这个问题只有2-3篇帖子，而且都没有解释它的含义！

这是另一个警告，我找到了一篇类似的帖子，但是它没有提供解决方法！

下一个警告是:

我觉得这是GoogleMaps API的问题，而不是我的代码问题，但我不能确定。

如果需要，我很乐意提供更多信息，但是我的项目有大约11-12k行代码，所以我不知道该上传什么。

更新到Xcode9后，我也遇到了类似的问题。 - Guri S

是的，这个也有。在模拟器中，UI线程被锁定了。 - Herm

我的项目非常小，只是一个带有聚类的地图，但在更新到Xcode9之后，我也开始遇到了这个问题。此外，地图本身现在感觉非常缓慢，至少在模拟器上是这样。 - AAverin

使用 GoogleMaps (2.4.0) / XCode - 版本 9.0 (9A235)，地图初始化出现相同的问题。 - Nazir

关于在iOS 11模拟器中检测到的缓慢问题，请参考与苹果相关的开放雷达问题： http://www.openradar.me/33505938 - Prags

Answer 1

这个问题也在Google问题跟踪器中报告：

https://issuetracker.google.com/issues/63322270

Google已经意识到了这个问题，目前的bug状态是Accepted，我期望在Google Maps SDK库2.5.0的下一个版本中修复它。

请随意在bug中添加星号以投票并订阅来自Google的通知。

更新

这个问题今天（2017年10月24日）被标记为已解决。Google代表写道：

我们认为这个问题应该在Maps iOS SDK v2.5版本中得到解决。如果这个问题仍然存在，请告诉我们。

谢谢您提供的信息。我会在这个 bug 上加一个星标。 - Persian

Answer 2

问题在于我使用了一个库来更改系统字体，但字体名称中有一个拼写错误，这就是为什么出现了这个奇怪的崩溃。
