What is the UITextField default borderColor in iOS8?

Question

I have a button with a border that I want to style as a UITextField.

So I tried:

self.dateButton.layer.borderColor = self.assesseeName.layer.borderColor

But that gives me a black border:

How do I get the same color as the UITextField (top of screenshot)?

Answer 1

I set the border color for the button to be the standard light gray and the border width to be 0.25 and that matched

Swift 3:

myButton.layer.borderWidth = 0.25
myButton.layer.borderColor = UIColor.lightGray.cgColor

Answer 2

You can use the following code to apply same effect of textfield to buttton (borderwidth, bordercolor, & corner radius)

UIColor *borderColor = [UIColor colorWithRed:204.0/255.0 green:204.0/255.0 blue:204.0/255.0 alpha:1.0];

dateButton.layer.borderColor = borderColor.CGColor;   
dateButton.layer.borderWidth = 1.0;
dateButton.layer.cornerRadius = 5.0;

Answer 3

根据 Mac 的数字色度计，边框的 RGB 为 230、230、230。

Answer 4

Swift 4 Answer

Textfield default border color is gray.

button.layer.borderColor = UIColor.gray.cgColor
button.layer.borderWidth = 0.15

Answer 5

In iOS 13 the color changes between light and dark mode

if #available(iOS 13.0, *) {
    view.layer.borderColor = UIColor(dynamicProvider: { trait in
        if trait.userInterfaceStyle == .light {
            return UIColor(white: 0, alpha: 0.2)
        } else {
            return UIColor(white: 1, alpha: 0.2)
        }
    }).cgColor
} else {

    view.layer.borderColor = UIColor(white: 0, alpha: 0.2).cgColor
}

This worked for me

let borderColor = UIColor(displayP3Red: 204.0/255.0, green: 204.0/255.0, blue: 204.0/255.0, alpha: 1.0)
uitextfield.borderColor = borderColor
uitextfield.borderWidth = 0.5
uitextfield.cornerRadius = 5
