MJRefresh

SPM supported Carthage compatible podversion

  • An easy way to use pull-to-refresh

📜✍🏻Release Notes: more details

Contents

New Features

Support Flips In CollectionViewLayout

Refer to issue #1616.

  • Use additionalFlipsViews to append views that need to flip when collectionViewLayout flipsHorizontallyInOppositeLayoutDirection is true.
  • Use flipsHorizontallyInOppositeLayoutDirectionViews to modify views as the same way above. ⚠️ BUT parent class may be affected. Use additionalFlipsViews instead.

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

  1. 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()
}
  1. Receiving MJRefreshDidChangeLanguageNotification notification.

SPM Supported

Released from 3.7.1

Swift Chaining Grammar Supported

  // Example as MJRefreshNormalHeader
  func addRefreshHeader() {

Reference

* Due to there are more functions of this framework，Don't write specific text describe its usage
* You can directly reference examples MJTableViewController、MJCollectionViewController、MJWebViewController，More intuitive and fast.
