任何解决此问题的线索都会很棒。

在使用以下步骤从“设置”->“键盘”中删除表情符号键盘后，我能够产生不再发生崩溃的场景。

1. 打开“设置”应用。
2. 转到“常规”>“键盘”，然后点按顶部的“键盘”。 (它旁边会有一个数字 - 那是您安装的键盘的数量。)
3. 点击编辑，然后点击表情符号旁边的红色圆圈。
4. 点击删除。

这个解决方案是 Not Acceptable ，我们不能要求我们的客户按照这些步骤操作，我们最好有一个崩溃的解决方案。

Answer 1

在我的例子中，这是因为 AppleLanguages 属性不正确；它被设置为 NSObject，但没有设置为 NSArray。

错误:

NSUserDefaults.StandardUserDefaults["AppleLanguages"] = NSArray.FromObject(new NSString("en-US"));

应该是:

NSUserDefaults.StandardUserDefaults["AppleLanguages"] = NSArray.FromObjects(new NSString("en-US"));
