首先，设置leftBtnclick.tag=999和rightBtnclick.tag=1000。

然后添加这段代码:-

-(void)leftTickBtnClicked:(id)sender
{
    UIButton *leftTickBtn=(UIButton *)sender;
    leftTickBtn.selected=!leftTickBtn.selected;
    for(UIView *vw in [[sender superview]subviews])
    {
        if([vw isKindOfClass:[UIButton class]] && vw.tag==1000)
        {
            UIButton *rightTickBtn=(UIButton *)vw;

            if(leftTickBtn.selected)
            {
                rightTickBtn.selected=NO;
            }
            else
            {
                rightTickBtn.selected=YES;
            }

        }
    }

}
-(void)rightTickBtnClicked:(id)sender
{

    UIButton *rightTickBtn=(UIButton *)sender;
    rightTickBtn.selected=!rightTickBtn.selected;


    for(UIView *vw in [[sender superview]subviews])
    {
        if([vw isKindOfClass:[UIButton class]] && vw.tag==999)
        {
            UIButton *leftTickBtn=(UIButton *)vw;

            if(rightTickBtn.selected)
            {
                leftTickBtn.selected=NO;
            }
            else
            {
                leftTickBtn.selected=YES;
            }

        }
    }


}
