ios - iOS/Swift::在初始化期间，HERE map 偶尔会崩溃=> [NSCFString hac_toVariant]

Question

我目前在使用HEREMaps的两个不同项目中面临一个问题。通过NMAApplicationContext.set(...)初始化后，应用程序立即崩溃，并显示以下日志:

libc++ abi.dylib:以NSException类型的未捕获异常终止

有人面临同样的问题吗？任何的想法？
消除此错误的唯一方法是卸载/安装应用程序。

亲切的问候，

好的，简短更新...该错误很容易重现。

1.)从[link] https://developer.here.com/mobile-sdks/documentation/ios-starter/topics/quick-start.html下载示例代码

2)按照以下步骤包含NMAKit框架和NMAKit bundle 包

3.)生成并运行(Xcode版本8.3.2(8E2002))。目标模拟器/硬件无关紧要(尝试使用iPhone 6/7 / s模拟器和硬件)。即使使用Obj-c或Swift样本也没有任何区别。

首先，一切都很好。第二次启动会导致崩溃。

Answer 1

感谢您报告此问题，这是由于我们使用HERE SDK中的Objective-C类别并将其作为静态库提供的。您可以做的一件事是将-ObjC链接器标志添加到您的内部版本(OTHER_LDFLAGS)中来解决此问题。

这将在将来的版本中修复。
