Multivalue type settings bundle fields alway return null

Question

I have a problem retrieving default values from the settings bundle when first launching an App. All non-multivalue fields return the default correctly. All multivalue field

Answer 1

I just ran into this problem and I ask myself why the settings bundle provides a default value, if this value can never be read from the NSUserDefaults.

I created a swift extension that does the following:

• Read the value for a given key
• If the key does not exist set a default and return this default

So I can do this:

NSUserDefaults.standardUserDefaults().settignsStringValue("MYPREFS_DOMAIN", defaultValue: "domain.com")

This is the extension:

extension NSUserDefaults{

    func settingsBoolValue(key: String, defaultValue: Bool) -> Bool{
        // The case for Bool is different as it would return `false` when the key is not set.
        if let v: AnyObject = self.objectForKey(key){
            // The boolean value exists
        } else {
            self.setObject(defaultValue, forKey: key)
        }

        return self.boolForKey(key)
    }

    func settingsStringValue(key: String, defaultValue: String) -> String{
        if let v = self.stringForKey(key){
            return v
        } else {
            self.setObject(defaultValue, forKey: key)
            return defaultValue
        }
    }
}
