嗨,我得到以下错误,到目前为止无法解决它.

Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_GAI", referenced from:
  objc-class-ref in AppDelegate.o objc-class-ref in HomeViewController.o  "_OBJC_CLASS_$_GAITrackedViewController", referenced from: _OBJC_CLASS_$_HomeViewController in HomeViewController.o "_OBJC_METACLASS_$_GAITrackedViewController", referenced from: _OBJC_METACLASS_$_HomeViewController in HomeViewController.o ld: symbol(s) not found for architecture x86_64

任何帮助,将不胜感激.提前致谢 !

我已经通过stackOverFlow和谷歌搜索,但没有找到我的查询的正确答案.我想使用命令行工具(来自mac系统)发送命令在iOS设备中启动应用程序(通过USB端口连接).请不要在评论或帖子中复制粘贴链接,因为我经历了很多网站.我期待一个正确的方式,以及理解是否有人可以提供.

我见过ios-deploy,libimobiledevice,但没有给出关于如何安装和使用的解释,即测试它是否正常工作.如果有人那么请提供相同的解释.

提前致谢.

到目前为止,我可以使用adb命令点击,滑动,解锁,安装/卸载和启动应用程序,但无法使用adb命令查找如何执行放大/缩小.

我有一些捏合进/出的坐标,但没有理解如何使用来自终端的adb命令来解雇它们.

例如,我们有命令 - > adb shell输入tap xy所以在这里我们可以用值/坐标替换x和y同样我想知道模拟插入/缩小的方法.

我得到的有关插入的坐标如下.
