具有 Interface Builder 用户定义的运行时属性的本地化字符串

Question

I am currently trying to create a localized accessibilityLabel in the storyboard (I am trying to avoid doing it programatically). It seems that whenever I use the Localized String option, the accessibilityLabels ends up being set to the localized string key that I have provided rather than the string itself. Does anyone have the solution to this problem? Any help would be greatly appreciated.

Answer 1

I guess you expect the localized string to be taken from Localizable.strings. The "Localized String" type doesn't work this way, it's just a marker to indicate that the value of the user defined runtime attribute will participate in the localization process when you use base localization. Please take a look at https://stackoverflow.com/a/24527990/2876231 for a lengthier explanation.

Answer 2

The attribute type needs to be Localizable String , and then you'd translate it in the .strings file using the following property:

"KLc-fp-ZVK.ibExternalUserDefinedRuntimeAttributesLocalizableStrings[0]" = "¡Hola!";

Unfortunately, it doesn't seem to work with a named attribute, but only with the long property above.

(Based on Andrew's answer here: Localize a view within a storyboard using "User Defined Runtime Attributes" )

Answer 3

I did the customization of an attribute with the simple solution of localizing the attribute by code:

private struct AssociatedKeys {
    static var someTagKey = "someTag"
}

@IBInspectable var someTag: String? {
    get {
       return NSLocalizedString(
            objc_getAssociatedObject(self, &AssociatedKeys.someTagsKey) as? String ?? "", comment: "")
    }
    set {
        if let newValue = newValue {
            objc_setAssociatedObject(
                self,
                &AssociatedKeys.someTagsKey,
                newValue as NSString?,
                objc_AssociationPolicy.OBJC_ASSOCIATION_RETAIN_NONATOMIC
            )
        }
    }
}

And after that you can easily extract all the strings from the xib and storyboard files with an egrep:

egrep -ohr --include="*.xib" --include="*.storyboard" '<userDefinedRuntimeAttribute type="string" keyPath="someTag" value="[^"]+"/>' . >> extracted-strings.txt

And after that eliminate the tags in the strings file by the following sed and then you have to plain strings file for xcode ready:

sed -i -e 's/^<userDefinedRuntimeAttribute type="string" keyPath="someTag" value=\("[^"]*"\)\/>/\1 = \1;/g' extracted-strings.txt
