-[NSRunningApplication activateWithOptions:] 不工作

Question

我正在尝试创建一个将专注于特定应用程序（如果已启动）的程序。这是我的代码：

#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;
}

当我运行这样做时，它会打印 "failed to activate," 并且 Firefox 没有进入焦点。我做错了什么？

Answer 1

只需使用 NSApplicationActivateIgnoringOtherApps 修饰符激活即可。工作正常。

另外activateWithOptions:方法有以下注意事项：

This method will return NO if the application has quit, or is not a type of application than can be activated.
