当我单击标签时，快速打开底部的日期选择器，并带有完成和取消按钮

Question

我正在使用 swift 和以下代码在 iphone 中制作应用程序

override func viewDidLoad() {
    //<#code#>
    dateSet.userInteractionEnabled = true
    let aSelector : Selector = "lblTapped"
    let tapGesture = UITapGestureRecognizer(target: self, action: aSelector)
    tapGesture.numberOfTapsRequired = 1

    dateSet.addGestureRecognizer(tapGesture)
}



func lblTapped(){
 // need to add datapicker UIView
}

Answer 1

使用文本字段inputView让日期选择器显示在底部。示例代码如下

私有(private)函数 dateTextFieldSetup()

    {
        let datePickerView  : UIDatePicker = UIDatePicker()
    datePickerView.datePickerMode = UIDatePickerMode.Date
    sampleTextfield.inputView = datePickerView
    datePickerView.addTarget(self, action:#selector(CFTextField.handleDatePickerForSlectedText(_:)), forControlEvents: UIControlEvents.ValueChanged)

}

对于 UILabel inputView 属性不可用。
