执行ionic cap build ios遇NSLocationWhenInUseUsageDescription错误求助

错误根源 #

你的info.plist存在XML结构错误：UIViewControllerBasedStatusBarAppearance这个key未配置对应的值，后续直接跳转至下一个keyNSLocationWhenInUseUsageDescription，而原本属于前者的<true/>被错误放置在位置权限描述之后，导致plist解析器无法识别非法结构，从而抛出Unexpected key "NSLocationWhenInUseUsageDescription" while parsing <dict/>错误。

修复后的完整info.plist代码 #

将<true/>移至UIViewControllerBasedStatusBarAppearance的key后方，修正后的代码如下：

<?xml version="1.0" encoding="UTF-8"?>

</dict>
</plist>

后续步骤 #

1. 替换项目中原有的info.plist文件内容
2. 重新执行ionic cap build ios命令，此时解析错误会消失，Xcode也能正常打开并显示plist文件
