我尝试在我的PickerView中选择一行,但它不起作用.它停留在第一排.
原文链接：https://www.f2er.com/swift/319259.html这是我的代码：
@IBOutlet weak var pickerView: UIDatePicker!
func numberOfComponentsInPickerView(pickerView: UIPickerView!) -> Int
{
return 1
}
func pickerView(pickerView: UIPickerView!,numberOfRowsInComponent component: Int) -> Int
{
return 10
}
func pickerView(pickerView: UIPickerView!,titleForRow row: Int,forComponent component: Int) -> String!{
return String(row + 1)
}
//In viewDidLoad
pickerView.selectRow(6,inComponent: 0,animated: true)
pickerView运行良好,显示1到10但selectRow不起作用.
它应该选择第六行,但它保留在第一行.
