Ios 将inputView背景颜色从模糊灰色更改为其他颜色

我正在尝试将

inputView

背景色从默认的浅灰色更改为其他颜色，但是我看不到任何解决方案

我有一个UIPickerView，当用户触摸

textField

时会打开它，它就像底部的键盘一样

inputView

。我是这样实现的：

myTextField.inputView=myPickerView

由于我在inputView中使用它，我想我实际上必须更改它的背景颜色，但不知道如何更改

看起来是这样的：

现在我想改变它的背景色

我已经试过了：

myPickerView.setValue（0.8，forKey:“alpha”）

myPckerView.backgroundColor=UIColor.blue

self.inputView.backgroundColor=UIColor.blue

几乎所有的解决方案都是如此

这是输出（上面有一些令人讨厌的模糊层）：

我是否需要为此创建某种自定义键盘，或者是否有解决方法，或者苹果会再次告诉你可以做什么，你不喜欢机器人吗？

使用此代码

mytextfield.inputView?.tintColor = UIColor.green

或者也试试这个

mytextfield.inputView?.tintColor = UIColor.clear
mytextfield.inputView?.backgroundColor = UIColor.blue

好的-由于您可以在“正常”视图中获得所需的

UIPickerView

外观，因此您可以创建一个“正常”视图用作

.inputView

，然后将选择器视图添加为子视图

下面是一个简单的示例-只需在IB中添加一个

UITextField

，并将其连接到

IBOutlet

：

class MyViewController: UIViewController
{

    @IBOutlet weak var theTextField: UITextField!

    let cancelButton: UIButton = {
        let b = UIButton()
        b.setTitle("Cancel", for: .normal)
        b.translatesAutoresizingMaskIntoConstraints = false
        return b
    }()

    let doneButton: UIButton = {
        let b = UIButton()
        b.setTitle("Done", for: .normal)
        b.translatesAutoresizingMaskIntoConstraints = false
        return b
    }()

    let pvToolbar: UIView = {
        let v = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 40))
        v.translatesAutoresizingMaskIntoConstraints = false
        v.backgroundColor = .black
        return v
    }()

    let pvBackground: UIView = {
        let v = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 10))
        v.backgroundColor = .white
        v.translatesAutoresizingMaskIntoConstraints = false
        return v
    }()

    let pickerView: UIPickerView = {
        let p = UIPickerView(frame: CGRect(x: 0, y: 0, width: 10, height: 10))
        p.showsSelectionIndicator = true
        p.translatesAutoresizingMaskIntoConstraints = false
        return p
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        // add buttons to the inputAccessoryView "toolbar"
        pvToolbar.addSubview(cancelButton)
        pvToolbar.addSubview(doneButton)

        cancelButton.leftAnchor.constraint(equalTo: pvToolbar.leftAnchor, constant: 8.0).isActive = true
        cancelButton.topAnchor.constraint(equalTo: pvToolbar.topAnchor, constant: 6.0).isActive = true
        cancelButton.bottomAnchor.constraint(equalTo: pvToolbar.bottomAnchor, constant: -6.0).isActive = true

        doneButton.rightAnchor.constraint(equalTo: pvToolbar.rightAnchor, constant: -8.0).isActive = true
        doneButton.centerYAnchor.constraint(equalTo: cancelButton.centerYAnchor).isActive = true

        // add pickerView to our plain UIView that will become our inputView
        pvBackground.addSubview(pickerView)

        pickerView.topAnchor.constraint(equalTo: pvBackground.topAnchor).isActive = true
        pickerView.bottomAnchor.constraint(equalTo: pvBackground.bottomAnchor).isActive = true
        pickerView.centerXAnchor.constraint(equalTo: pvBackground.centerXAnchor).isActive = true
        pickerView.widthAnchor.constraint(equalTo: pvBackground.widthAnchor, multiplier: 1.0).isActive = true

        pickerView.delegate = self
        pickerView.dataSource = self

        // pvBackground "contains" the actual pickerView
        theTextField.inputView = pvBackground

        theTextField.inputAccessoryView = pvToolbar

    }

}

extension AnimConstraintsViewController:  UIPickerViewDelegate, UIPickerViewDataSource {

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return "Row: \(row)"
    }

    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return 30
    }

    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }

    func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
        // simple label with centered text as our viewForRow
        let label = UILabel()
        label.backgroundColor = .white
        label.textColor = .black
        label.textAlignment = .center
        label.font = UIFont.systemFont(ofSize: 17.0, weight: UIFontWeightRegular)
        label.text = "Row: \(row)"
        return label
    }
}

您是否尝试过使用

myTextField.inputView.backgroundColor=UIColor.blue

。什么是self.inputView？@Subramanian是的，我也试过了。根据文档，当对象成为第一响应者时，“

self.inputView

被”//调用并显示。进入响应者链。”。基本上，它用

UIPickerView

@TarvoMäesepp替换了键盘-你希望它看起来怎么样？这是使用

UIPickerView

作为

inputView

的一个示例（我怀疑您是否想要这些颜色）：@DonMag我希望它看起来平坦。没有你的前一层是蓝色的在我的图像。我甚至不知道滚动效果。类似于@TarvoMäesepp的东西-你能在你的普通视图中（而不是作为inputView的一部分）在UIPickerView中获得你想要的外观吗？你太棒了。为什么我没有想到这个主意。正是我想要的。
