New Features

Dynamic i18n Switching

Now MJRefresh components will be rerendered automatically with MJRefreshConfig.default.language setting.

Example

Go i18n folder and see lots of cases. Simulator example is behind i18n tab in right-top corner.

Setting language

MJRefreshConfig.default.language = "zh-hans"

Setting i18n file name

MJRefreshConfig.default.i18nFilename = "i18n File Name(not include type<.strings>)"

Setting i18n language bundle

MJRefreshConfig.default.i18nBundle = <i18n Bundle>

Adopting the feature in your DIY component

Just override i18nDidChange function and reset texts.

// must use this localization methods
Bundle.mj_localizedString(forKey: "")
// or
Bundle.mj_localizedString(forKey: "", value:"")

override func i18nDidChange() {
    // Reset texts function
    setupTexts()
    // Make sure to call super after resetting texts. It will call placeSubViews for applying new layout.
    super.i18nDidChange()
}

Receiving MJRefreshDidChangeLanguageNotification notification.
