Do you think we are missing an alternative of BlockiesSwift or a related project?
This library is a Swift implementation of the Ethereum fork of Blockies which is intended to be used in iOS, watchOS, tvOS and macOS apps.
Blockies generates unique images (identicons) for a given seed string. Those can be used to create images representing an Ethereum (or other Cryptocurrency) Wallet address or really anything else.
To run the example project, run
pod try BlockiesSwift. Or clone the repo, and run
pod install from the Example directory.
BlockiesSwift is available through CocoaPods. To install
it, simply add the following line to your
BlockiesSwift is compatible with Carthage, a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To install it, simply add the following line to your
Basic usage is very straight forward. You just create an instance of
Blockies with your seed and call
createImage() to get your image.
import BlockiesSwift let blockies = Blockies(seed: "0x869bb8979d38a8bc07b619f9d6a0756199e2c724") let img = blockies.createImage() yourImageView.image = img
This will generate an image with
size set to 8 and
scale set to 4.
size is the width and height of the Blockies image in blocks,
scale is the width and height of one block in pixels.
Per default, random colors are generated for the given seed. You can change that but keep in mind that the pattern will also change if you provide custom colors as there will be less calls to the internal
The following is a full example.
import BlockiesSwift let blockies = Blockies( seed: "0x869bb8979d38a8bc07b619f9d6a0756199e2c724", size: 5, scale: 10, color: UIColor.green, bgColor: UIColor.gray, spotColor: UIColor.orange ) let img = blockies.createImage() yourImageView.image = img
The following sizes work well for most cases.
- size: 8, scale: 3
- size: 5, scale: 10
Sizes above 10 generate more noisy structures. If you want to generate bigger images, you can go for a set of
scale from the above and pass a
customScale value to
import BlockiesSwift let blockies = Blockies( seed: "0x869bb8979d38a8bc07b619f9d6a0756199e2c724", size: 8, scale: 3 ) let img = blockies.createImage(customScale: 10) yourImageView.image = img
The image in this example would be
8 * 3 = 24x24 pixels without a custom scale. With the
customScale set to
10 it will be
8 * 3 * 10 = 240x240 pixels. The
customScale lets you generate bigger images with the same structure quality as the smaller ones.
