Question

我将UIPickerView作为UITextField的输入，并使用＆＃34;完成＆＃34;实现UIToolbar。按钮。它完美无缺，但当我在iPhone上切换到横向模式时，UIToolbar消失了。这是我的代码：

override func viewDidLoad() {
    super.viewDidLoad()

    thePicker.delegate = self

    let toolBar = UIToolbar()
    toolBar.barStyle = UIBarStyle.default

    toolBar.isTranslucent = true
    toolBar.tintColor = UIColor(red: 76/255, green: 100/255, blue: 217/255, alpha: 1)
    toolBar.sizeToFit()

    let doneButton = UIBarButtonItem(title: "Aceptar", style: UIBarButtonItemStyle.plain, target: self, action: #selector(doneClick))


    toolBar.setItems([doneButton], animated: false)
    toolBar.isUserInteractionEnabled = true

    testTextField.inputView = thePicker
    testTextField.inputAccessoryView = toolBar

}

Answer 1

当我以编程方式添加UIPickerView并为PickerView添加UIToolBar时，遇到了相同的问题。只需为UIPickerView添加[.flexibleWidth，.flexibleHeight]

self.thePicker.autoresizingMask = [.flexibleWidth,.flexibleHeight]

Swift - 用于UIPickerView的带有完成按钮的UIToolbar在横向上消失
