iOS 侧边栏崩溃

Question

设备：任何iOS设备

大家好，

当我尝试通过任何方式（单击三行按钮或通过滑动）激活它时，iOS 边栏出现问题。该错误仅发生在 iOS 平台上，在我尝试过的任何设备上（几个 iPhone 6 运行 iOS 9 和 iPad 1 运行 iOS 5).我通过将主题常量 commandBehavior 设置为 Side 并将命令添加到表单来简单地使用侧边栏。该应用程序完全冻结，我必须强行关闭它。

我附上从 iOS 设备之一获得的堆栈跟踪：

希望这足以确定此问题的可能原因。

感谢您的帮助。

Answer 1

这似乎与以下有关：

f.addCommand(new Command(null, icon));

将其更改为：

f.addCommand(new Command("", icon));

解决错误时产生相同的结果。我们已经在代码中添加了一个修复程序，这将是下一次服务器更新的一部分。
