我尝试根据代码是通过USB / Xcode(调试)运行还是从应用程序商店下载的生产模式(发布)来启用/禁用部分代码。我知道检查它是否在DEBUG
或RELEASE
模式下运行,如下所示:
#ifdef DEBUG
// Stuff for debug mode
#else
// Stuff for release mode
#endif
但问题是,我看到一个明显的循环漏洞,你可以改变运行'从' Debug'构建方案发布'。更好的方法是,如果我可以简单地检测它是否从Xcode运行。我还没有办法检查这个。
有没有办法检查iOS应用是否在Xcode上运行?

您可以使用sysctl
检查是否附加了调试器(可能,但不一定是Xcode)。这是HockeyApp does it:
#include <Foundation/Foundation.h>
#include <sys/sysctl.h>
/**
* Check if the debugger is attached
*
* Taken from https://github.com/plausiblelabs/plcrashreporter/blob/2dd862ce049e6f43feb355308dfc710f3af54c4d/Source/Crash%20Demo/main.m#L96
*
* @return `YES` if the debugger is attached to the current process, `NO` otherwise
*/
