Simulator example is behind `i18n tab` in right-top corner. #### Setting language ```swift MJRefreshConfig.default.language = "zh-hans" ``` #### Setting i18n file name ```swift MJRefreshConfig.default.i18nFilename = "i18n File Name(not include type<.strings>)" ``` #### Setting i18n language bundle ```swift MJRefreshConfig.default.i18nBundle = <i18n Bundle> ``` #### Adopting the feature in your DIY component 1. Just override `i18nDidChange` function and reset texts. ```swift // 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() } ``` 2. Receiving `MJRefreshDidChangeLanguageNotification` notification. ### <a id="spm_supported"></a>SPM Supported Released from [`3.7.1`](https://github.com/CoderMJLee/MJRefresh/releases/tag/3.7.1) ### <a id="swift_chaining_grammar_supported"></a>Swift Chaining Grammar Supported ```swift // Example as MJRefreshNormalHeader func addRefreshHeader() { MJRefreshNormalHeader { [weak self] in // load some data }.autoChangeTransparency(true) .link(to: tableView) } ``` ## <a id="Support_what_kinds_of_controls_to_refresh"></a>Support what kinds of controls to refresh * `UIScrollView`、`UITableView`、`UICollectionView`、`WKWebView` ## <a id="How_to_use_MJRefresh"></a>How to use MJRefresh * Installation with CocoaPods：`pod 'MJRefresh'` * Installation with [Carthage](https://github.com/Carthage/Carthage)：`github "CoderMJLee/MJRefresh"` * Manual import： * Drag All files in the `MJRefresh` folder to project * Import the main file：`#import "MJRefresh.h"` ```objc Base Custom MJRefresh.bundle MJRefresh.h MJRefreshConst.h MJRefreshConst.m UIScrollView+MJExtension.h UIScrollView+MJExtension.m UIScrollView+MJRefresh.h UIScrollView+MJRefresh.m UIView+MJExtension.h UIView+MJExtension.m ``` ## <a id="More_than_hundreds_of_Apps_are_using_MJRefresh"></a>More than hundreds of Apps are using MJRefresh <img src="http://images0.cnblogs.com/blog2015/497279/201506/141212365041650.png" width="200" height="300"> * More information of App can focus on：[M了个J-博客园](http://www.cnblogs.com/mjios/p/4409853.html) ## <a id="The_Class_Structure_Chart_of_MJRefresh"></a>The Class Structure Chart of MJRefresh  - `The class of red text` in the chart：You can use them directly - The drop-down refresh control types - Normal：`MJRefreshNormalHeader` - Gif：`MJRefreshGifHeader` - The pull to refresh control types - Auto refresh - Normal：`MJRefreshAutoNormalFooter` - Gif：`MJRefreshAutoGifFooter` - Auto Back - Normal：`MJRefreshBackNormalFooter` - Gif：`MJRefreshBackGifFooter` - `The class of non-red text` in the chart：For inheritance，to use DIY the control of refresh - About how to DIY the control of refresh，You can refer the Class in below Chart<br> <img src="http://images0.cnblogs.com/blog2015/497279/201506/141358159107893.png" width="30%" height="30%"> ## <a id="MJRefreshComponent.h"></a>MJRefreshComponent.h ```objc /** The Base Class of refresh control */ @interface MJRefreshComponent : UIView #pragma mark - Control the state of Refresh /** BeginRefreshing */ - (void)beginRefreshing; /** EndRefreshing */ - (void)endRefreshing; /** IsRefreshing */ - (BOOL)isRefreshing; #pragma mark - Other /** According to the drag ratio to change alpha automatically */ @property (assign, nonatomic, getter=isAutomaticallyChangeAlpha) BOOL automaticallyChangeAlpha; @end ``` ## <a id="MJRefreshHeader.h"></a>MJRefreshHeader.h ```objc @interface MJRefreshHeader : MJRefreshComponent /** Creat header */ + (instancetype)headerWithRefreshingBlock:(MJRefreshComponentRefreshingBlock)refreshingBlock; /** Creat header */ + (instancetype)headerWithRefreshingTarget:(id)target refreshingAction:(SEL)action; /** This key is used to storage the time that the last time of drown-down successfully */ @property (copy, nonatomic) NSString *lastUpdatedTimeKey; /** The last time of drown-down successfully */ @propert
