iOS14 - How to change textColor of UIDatePicker in UIKit?

Question

Using iOS14.0.1, Swift5.3, Xcode12.0.1,

I try to change the textColor of a UIDatePicker in iOS14 and using UIKit.

I read here that you need the following method to do so:

let myDatePicker = UIDatePicker()
myDatePicker.tintColor = .white

---

I also tried the following (but that makes my app crash under iOS14):

myDatePicker.setValue(UIColor.white, forKeyPath: "textColor")

---

I also tried (but without success either):

UILabel.appearance(whenContainedInInstancesOf: [UIDatePicker.self]).textColor = UIColor.white

---

In light mode, none of my trials work (as can bee seen in the screenshot-excerpt):

What do I need to do to get the white color text in my UIDatePicker?

Answer 1

Try this, add the extension below:

extension UIDatePicker {

var textColor: UIColor? {
    set {
        setValue(newValue, forKeyPath: "textColor")
    }
    get {
        return value(forKeyPath: "textColor") as? UIColor
    }
  }
}

Now in viewDidLoad call:

myDatePicker.textColor = .yourColor

call it after other picker property, es.:

myDatePicker.preferredDatePickerStyle = .wheels
myDatePicker.addTarget(self, action: #selector(handleDatePicker), for: .valueChanged)
myDatePicker.datePickerMode = .dateAndTime
myDatePicker.timeZone = NSTimeZone.local
myDatePicker.backgroundColor = .black
myDatePicker.setValue(false, forKey: "highlightsToday")
myDatePicker.textColor = .yourColor // here

if you want highlightsToday set the relative picker value to true:

myDatePicker.setValue(true, forKey: "highlightsToday")

and this is the result:
