问题描述

我正在尝试创建一个程序,将某个应用程序(如果它启动)。这是我的代码:

I'm trying to create a program that will focus a certain application (if it is launched). Here is my code:

#import <Cocoa/Cocoa.h>
#import <stdio.h>

int main() {
  // activate Firefox
  NSArray *apps = [NSRunningApplication runningApplicationsWithBundleIdentifier: @"org.mozilla.firefox"];

  if ([apps count] == 0) {
    printf("no matching app\n");
    return 1;
  }

  if (![apps[0] activateWithOptions: NSApplicationActivateAllWindows]) {
    printf("failed to activate\n");
    return 1;
  }

  return 0;
}

当我运行这个,它打印无法激活,没有引起注意。

When I run this, it prints "failed to activate," and Firefox is not brought into focus. What am I doing wrong?
