InitialImageView is a subclass of UIImageView that empower user to set initial or name as a placeholder image like what you see in a iOs Contact

Use CocoaPods with Podfile:

pod 'InitialImageView'

Just drag and drop InitialImageView.swift to your project.

@IBOutlet weak var initialImageView: InitialImageView!

override func viewDidLoad() {
  super.viewDidLoad()
  initialWithFontImageView.setImageWithInitial("YW", backgroundColor: UIColor.greenColor())
}

override func viewDidLoad() {
  super.viewDidLoad()
  let initialImageView = InitialImageView(frame: CGRect(x: 0, y: 0, width: 80, height: 80))
  initialWithFontImageView.setImageWithInitial("YW", backgroundColor: UIColor.greenColor())
}

profileImageView.setImageWithFirstName(user.firstName, lastName: user.lastName)
profileImageView.af_setImageWithURL(user.profileUrl)

1. Create or change your UIImageView to InitialImageView

2. Call any of the following function to set image for InitialImageView

   func setImageWithFirstName(firstName: String, lastName: String, backgroundColor: UIColor = UIColor.darkGrayColor(), randomColor: Bool = false) func setImageWithInitial(initial: String, backgroundColor: UIColor = UIColor.darkGrayColor(), randomColor: Bool = false) func setImageWithInitial(initial: String, backgroundColor: UIColor = UIColor.darkGrayColor(), randomColor: Bool = false)

backgroundColor default is UIColor.darkGrayColor() however it can be set by any UIColor that user has passed in when calling the function.

randomColor default is false. By setting randomColor to true, it will ignore the backgroundColor parameters and generate a random UIColor that is not 'near' white.

3. Properties:

The following properties could be set if needed to override the default value

var fontResizeValue: CGFloat
var font: UIFont
var isCircle: Bool

fontResizeValue is used to calculate the font size with self.bounds

font will be used to draw the initial UIImage that will be set to InitialImageView. Setting fontsize on 'font' here will not take any effect

isCircle is a boolean that will determine if InitialImageView should be a circle

This project draw inspiration from UIImageView+Letters in Objective-c. I have used the Pods multiple time in Objective-c project. I decided to write it in Swift with a few changes and also turning it into a subclass instead.
