LetterAvatarKit provides an UIImage extension for generating letter-based avatars/placeholders. There are a few images showing what you can achive by using this framework:
- iOS 8+
- tvOS 9+
- Swift 4.0+
- Easy to use and intuitive interface
- Highly flexible API allows for customization and integration into various projects
- Use of the builder pattern for constructing avatar configurations
- Support for creating circular, square, or bordered images
- Wide range of flat UI colors available
- Compatible with tvOS platform
LetterAvatarKit is available through CocoaPods. To install
it, simply add the following line to your Podfile:
pod "LetterAvatarKit", "1.2.5" # Swift 5.0+, Xcode 12
pod "LetterAvatarKit", "1.2.3" # Swift 5.0+, Xcode 11
pod "LetterAvatarKit", "1.1.7" # Swift 4.2
pod "LetterAvatarKit", "1.1.5" # Swift 4.0Add this to Cartfile
github "vpeschenkov/LetterAvatarKit" == 1.2.5 # Swift 5.0+, Xcode 12

// Square avatar image
let avatarImage = LetterAvatarMaker()
.setUsername("Letter Avatar")
.build()
avatarImageView.image = avatarImage
// Circle avatar image with white border
let circleAvatarImage = LetterAvatarMaker()
.setCircle(true)
.setUsername("Letter Avatar")
.setBorderWidth(1.0)
.setBackgroundColors([ .red ])
.build()
avatarImageView.image = circleAvatarImageUsing LetterAvatarMaker with closures:
let avatarImage = LetterAvatarMaker()
.build { c in
c.username = "Letter Avatar"
}
avatarImageView.image = avatarImage
let avatarImage = LetterAvatarMaker()
.build { c in
c.circle = true
c.username = "Letter Avatar"
c.borderWidth = 1.0
c.backgroundColors = [ .red ]
}
avatarImageView.image = avatarImageUsing LetterAvatarBuilderConfiguration:
let configuration = LetterAvatarBuilderConfiguration()
configuration.username = "Letter Avatar"
avatarImageView.image = UIImage.makeLetterAvatar(withConfiguration: configuration)Using UIImage extension:
avatarImageView.image = UIImage.makeLetterAvatar(withUsername: "Letter Avatar")Using LKLetterAvatarBuilderCongiguration:
LKLetterAvatarBuilderCongiguration *configuration = [[LKLetterAvatarBuilderCongiguration alloc] init];
configuration.username = @"Letter Avatar";
self.avatarImageView.image = [UIImage lk_makeLetterAvatarWithConfiguration:configuration];Using UIImage extension:
self.avatarImageView.image = [UIImage lk_makeLetterAvatarWithUsername:@"Letter Avatar"];You can configure the following properties of LetterAvatarBuilderConfiguration:
/// The username.
open var username: String?/// The size of an avatar image.
open var size: CGSize = CGSize(width: 80, height: 80)/// The flag that indicates of using single only one letter, otherwise,
/// as much as wil be possible to obtain. But no more than 3 letters.
open var isSingleLettered: Bool = false/// The letters font.
open var lettersFont: UIFont = UIFont.systemFont(ofSize: 16.0)/// The letters colors
open var lettersColor: UIColor = LKUIColorByRGB(red: 236, green: 240, blue: 241)/// The background colors of an image.
open var backgroundColors: [UIColor] = UIColor.colors/// The letters font attributes.
open var lettersFontAttributes: [NSAttributedString.Key: Any]?/// Indicates whether to generate circle or square image.
open var circle: Bool = false/// The border width of the image.
open var borderWidth: CGFloat = 0.0/// The border color of the image.
open var borderColor: UIColor = UIColor.white/// A Boolean flag indicating whether the avatar is opaque.
open var opaque: Bool = falseQuestions, comments, issues, and pull requests are welcome!
