如何更改 UISegmentedControl 中禁用段的色调颜色

Question

如何更改 UISegmentedControl 中禁用段的色调颜色。 我得到了对 segmentedControl.subviews 进行排序的解决方案，下面是 swift 代码，请将其转换为目标 c。

@IBAction func indexChanged(sender: UISegmentedControl) {

let sortedViews = sender.subviews.sort( { $0.frame.origin.x < $1.frame.origin.x } )

for (index, view) in sortedViews.enumerate() {
    if index == sender.selectedSegmentIndex {
        view.tintColor = UIColor.blueColor()
    } else {
        view.tintColor = UIColor.lightGrayColor()
    }
}

}

let sortedViews = segmentedControlOutletVariable.subviews.sort( { $0.frame.origin.x < $1.frame.origin.x } )
sortedViews[0].tintColor = UIColor.blueColor()

检查以下代码：

1.它将绿色分配给选定的段。(segment-2)

2.将蓝色分配给未选中但启用的那些（segment-1 和 3）。

3.为禁用的段分配浅灰色。（段4）

-(IBAction)segmentedTapped:(UISegmentedControl*)sender{

for(int i=0;i<[sender.subviews count];i++)
{
    if ([[sender.subviews objectAtIndex:i]isEnabled])
    {


        if([[sender.subviews objectAtIndex:i]isSelected])
        {
            UIColor *tintcolor=[UIColor greenColor];
            [[sender.subviews objectAtIndex:i] setTintColor:tintcolor]; //sets green color for selected segment which is enabled
        }
        else
        {
            [[sender.subviews objectAtIndex:i] setTintColor:[UIColor blueColor]]; //sets blue colour for remaining segments which are enabled but not selected.

        }
    }
    else
    {
        [[sender.subviews objectAtIndex:i] setTintColor:[UIColor lightGrayColor]];//sets ight gray for disabled segment.
    }
}
}

结果将是：
