Question

在swift 3中，我无法在pickerview中设置工具栏，如

pickerFilter？.inputAccessoryView = barAccessory

错误是inputAccessoryView是get-only属性。

当我在Pickerview中添加子视图时。工具栏显示但完成按钮不可点击

任何解决方案？

Answer 1

let flexiblespace = UIBarButtonItem(barButtonSystemItem:.flexibleSpace , target: nil, action: nil)

    let btnDone = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(self.donePresed))
    let barAccessory = UIToolbar(frame: CGRect(x: 0, y: 0, width: viewPicker.frame.size.width, height: 44))
    barAccessory.barStyle = .default
    barAccessory.isTranslucent = true
    barAccessory.items = [flexiblespace,btnDone]

    viewPicker.addSubview(pickerDrpDown!)
    viewPicker.addSubview(barAccessory)

Answer 2

我认为您正在为inputAccessoryView分配UIPickerView，实际上您应该将其分配给您的相关textfield而不是pickerview自己！像，

   textField.inputAccessoryView = toolBar

Pickerview中无法设置inputAccessoryView工具栏
