推荐答案

我已经解决了这个问题，在Swift中回答：

I have solved this, answer in Swift:

var pickerView = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 300))
pickerView.backgroundColor = .whiteColor()
pickerView.showsSelectionIndicator = true

var toolBar = UIToolbar()
toolBar.barStyle = UIBarStyle.Default
toolBar.translucent = true
toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
toolBar.sizeToFit()


let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Bordered, target: self, action: "donePicker")
let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Bordered, target: self, action: "canclePicker")

toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true

textField.inputView = pickerView
textField.inputAccessoryView = toolBar
