将背景图像上方的文本添加到 uiswitch

Question

我的自定义 UISegmented 控件具有 [每个状态的] 背景图像。 How do I add text above the images [for each state, meaning that when index 0 will be selected I will have a specific color and font] ?

这是我的 UISegmented 控件的外观：

UISegmentedControl *customUISC=[[UISegmentedControl alloc] initWithItems:[[[NSMutableArray alloc] initWithObjects:@"ON",@"OFF",nil] autorelease]];

    [customUISC setFrame:CGRectMake(11,14,298,28)];
    customUISC.selectedSegmentIndex=0;
    customUISC.segmentedControlStyle=UISegmentedControlStyleBar;

    [customUISC setImage:[UIImage imageNamed:@"FirstTabActive.png"] forSegmentAtIndex:0];
    [customUISC setImage:[UIImage imageNamed:@"SecondTab.png"] forSegmentAtIndex:1];
    [customUISC addTarget:self action:@selector(checkOnOffState:) forControlEvents:UIControlEventValueChanged];

checkOnOffState 方法如下所示：

-(IBAction)checkOnOffState:(id)sender{

UISegmentedControl *iSeg=(UISegmentedControl *)sender;

if(iSeg.selectedSegmentIndex==0){

    [iSeg setImage:[UIImage imageNamed:@"FirstTabActive.png"] forSegmentAtIndex:0];
    [iSeg setImage:[UIImage imageNamed:@"SecondTab.png"] forSegmentAtIndex:1];
}
else {

    [iSeg setImage:[UIImage imageNamed:@"FirstTab.png"] forSegmentAtIndex:0];
    [iSeg setImage:[UIImage imageNamed:@"SecondTabActive.png"] forSegmentAtIndex:1];
}   
}

我不确定我是否完全理解您的需求，但您能否使用 UILabel（位于图片上方）。然后，您可以使用 myLabel.text 和 myLabel.textColor 轻松更改颜色和文本。

希望这在某种程度上有所帮助！
