推荐答案

在Interface Builder中连接好UISwitch后，你可以这样检查它是否开启:

After you hook up the UISwitch in Interface Builder, you can check if it's on like this:

-(IBAction) changeMode:(id)sender
{
     if ([(UISwitch *)sender on])
     {
          NSLog(@"The switch is on.");
     }
     else
     {
          NSLog(@"The switch is off.");
     }
}
