HexString

Convert Hex String into UIColor

Installation

Manual

Just copy the file ‘UIColor+HexString.swift’ into your project.

Usage

Get UIColor from Hex String

// If hex string is not valid, init with white color.
view.backgroundColor = UIColor(hexString: "#123456")

// This class method verifies hex string and return nil if it is not valid.
view.backgroundColor = UIColor.colorWithHexString("#123456")

Get Hex String from UIColor

NSLog("\(UIColor.red.hexString ?? "ERROR")")

The Result will be in the form of #RRGGBB or #AARRGGBB

There is also an extension for String class.

view.backgroundColor = "#123456".toColor()

Validate

FYI, above convenience init method and class method are checking if the string is hex color string, so this is not necessary if you use them.

if let hexString = UIColor.validateHexString("#123456") {
    // Do what you want
}

nil if the string is not a color hex string. Return the string when it is.

Available formats

• #RGB
• #ARGB
• #RRGGBB
• #AARRGGBB
