您可以使用检查是否已连接调试器（可能但并非绝对是Xcode） sysctl 。这是 HockeyApp做到的：

#include <Foundation/Foundation.h>
#include <sys/sysctl.h>

/**
 * Check if the debugger is attached

 *
 * @return `YES` if the debugger is attached to the current process, `NO` otherwise

- (BOOL)isDebuggerAttached {
  static BOOL debuggerIsAttached = NO;

  static dispatch_once_t debuggerPredicate;
  dispatch_once(&debuggerPredicate, ^{
    struct kinfo_proc info;
    size_t info_size = sizeof(info);
    int name[4];

    name[0] = CTL_KERN;
    name[1] = KERN_PROC;
    name[2] = KERN_PROC_PID;
    name[3] = getpid(); // from unistd.h, included by Foundation

    if (sysctl(name, 4, &info, &info_size, NULL, 0) == -1) {
      NSLog(@"[HockeySDK] ERROR: Checking for a running debugger via sysctl() failed: %s", strerror(errno));
      debuggerIsAttached = false;
    }

    if (!debuggerIsAttached && (info.kp_proc.p_flag & P_TRACED) != 0)
      debuggerIsAttached = true;
  });

  return debuggerIsAttached;
}
