README
# Misen
Misen is a script to support using Xcode Asset Catalog in Swift.
# Features
Misen scans sub-directories in the specified Asset Catalog and creates a UIImage extension file which has the following features.
- *Application-specific enum* which is constructed from Asset Catalog names and UIImage object can be instantiated directly from it.
- *UIImage non-failable initializer* whose argument is an enum value above.
# Usage
- Change file permissions first.
```
chmod +x misen.swift
```
- Run the script.
```
./misen.swift -path PATH/TO/XCASSETS -exportPath PATH/TO/GENERATED_FILE -enumName ENUM_NAME
```
- ```-path``` is a path of the asset catalog.
- ```-exportPath``` is an output UIImage extension file path.
- ```-enumName``` is an enum name to be generated. This is **optional** and ```ImageAsset``` is used as default when this parameter is not specified.
#### e.g.
Misen generates the file below from the asset catalog with 3 image sets below.
For reference, see the [**script**](Sample/generate.sh) of the sample project.
```swift
import UIKit
// MARK: - UIImage extension
extension UIImage {
convenience init!(assetName: ImageAsset) {
self.init(named: assetName.rawValue)
}
}
// MARK: - ImageAsset
enum ImageAsset: String {
case camera = "camera"
case contact = "contact"
case home = "home"
var image: UIImage {
return UIImage(named: self.rawValue)!
}
}
```
- In your code, you can instantiate images in Asset Catalog as follows.
```swift
class ViewController: UIViewController {
@IBOutlet weak var cameraImageView: UIImageView! {
didSet {
// Instantiate UIImage directly from ImageAsset enum
cameraImageView.image = ImageAsset.camera.image
}
}
@IBOutlet weak var contactImageView: UIImageView! {
didSet {
contactImageView.image = ImageAsset.contact.image
}
}
@IBOutlet weak var homeImageView: UIImageView! {
didSet {
// Instantiate UIImage with UIImage extension
homeImageView.image = UIImage(assetName: .home)
}
}
...
}
```
