在swift中向UIPicker添加内联标签

Question

我一直在寻找，无法想象我如何做以下事情。我有一个UIPickerView（如图所示）我已修改为允许我从中选择min和seconds但我还想添加像CountDownTimer UIPickerView（显示）这样的标签，这样用户就可以知道从几秒钟开始的分钟数。

有关如何添加内联标签的任何想法。

虽然不是很漂亮，可能是更好的方式，但你可以随时为＃34;小时＆＃34;创建一个单一的价值组件。并分别为＆＃34; min＆＃34;。

var hours = ["0","1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24"]
var hoursLabel = ["hours"]
var minutes = ["00","15","30","45"]
var minutesLabel = ["min"]

您可能还想调整列宽...这是一个例子。

//Adjust width of each picker column
func pickerView(pickerView: UIPickerView, widthForComponent component: Int) -> CGFloat {

    if (component == 1) {
        return 55 //hours label
    } else {
        return 40 // all others
    }
}
