Usage
It is possible to localize a class that conforms Localizable adding @Localized("YouKey") before the component declaration.
UILabel, UIButton, UITextField and UIImageView already conform Localizable.
// In the following example the string for the key "Label.Title" will be searched in the file "Localizable.strings".
@Localized("Label.Title")
@IBOutlet private var label: UILabel!If the strings are defined in a file different from Localizable.strings set the parameter stringsFileName with the name of the file.
// In the following example the string for the key "Label.Title" will be searched in the file "AFile.strings".
@Localized("Label.Title", stringsFileName: "AFile")
@IBOutlet private var label: UILabel!If the .strings file is in a bundle other than .main set the parameter bundle with the bundle where the file is embedded.
// In the following example the string for the key "Label.Title" will be searched in the file "AFile.strings" in the bundle `.anotherBundle`.
@Localized("Label.Title", stringsFileName: "AFile", bundle: .anotherBundle)
@IBOutlet private var label: UILabel!Set strings for state
It is possible to set different localized strings for different UIControl.State using the declaration @Localized(.key(, for:), .key(, for:) ..., stringsFileName:, bundle:).
The method .key(:, for: ) is a factory method to instantiate the object that associate a key to a state LocalizedConfiguration.
// In the following example the string for the key "Button.Title" will be set for the normal state and the string for the key "Button.Highlighted.Title" will be set for the highlighted state.
@Localized(.key("Button.Title", for: .normal),
.key("Button.Highlighted.Title", for: .highlighted))
@IBOutlet private var button: UIButton!It is possible to set stringsFileName and bundle just like in the examples above.
