安裝

手動安裝（正在準備CocoaPods）

將‘Harpy’文件夾拖入到你的項目中赂毯，并選擇'copy if needed',包括 Harpy.h 和 Harpy.m 文件

配置

1. import Harpy.h 導(dǎo)入到 AppDelefate 類中 或者 Pre-Complier Header(.pch)文件中
2. 在你的Appdelegate中設(shè)置appID（必要），
   設(shè)置你的alertType（可選）

appID獲取方法:

1拣宰、在iTunes中搜索到你的應(yīng)用：

2党涕、點擊箭頭：

Snip20160707_5.png

3、從鏈接中截取字符串
https://itunes.apple.com/cn/app/itunes-connect/id376771144?mt=8
其中：376771144就是他的AppID

3. 在你的Appdelegate中調(diào)用checkVersion方法巡社，三個檢測方法調(diào)用位置分別位于Appdelegate的啟動的代理方法中膛堤，可以自行選擇使用
   • 在 application:didFinishLaunchingWithOptions: 中調(diào)用 checkVersion
   • 在 applicationDidBecomeActive: 中調(diào)用 checkVersionDaily
   • 在 applicationDidBecomeActive: 中調(diào)用 checkVersionWeekly .

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    // 啟用Harpy之前確保你的window可用
    [self.window makeKeyAndVisible];

    // 為你的應(yīng)用設(shè)置app id
    [[Harpy sharedInstance] setAppID:@"<#app_id#>"];

    // 設(shè)置 UIAlertController 將要基于哪個控制器顯示 （適配iOS8+）
    [[Harpy sharedInstance] setPresentingViewController:_window.rootViewController];

  // (可選)設(shè)置代理來追蹤用戶點擊事件，活著的使用自定義的界面來展示你的信息
      [[Harpy sharedInstance] setDelegate:self];
    
    // (可選) 設(shè)置alertController的tincolor（iOS8+可用）
    [[Harpy sharedInstance] setAlertControllerTintColor:@"<#alert_controller_tint_color#>"];

    // (可選) 設(shè)置你的應(yīng)用名
    [[Harpy sharedInstance] setAppName:@"<#app_name#>"];

     /* （可選）設(shè)置彈框類型 默認為HarpyAlertTypeOption */
    [[Harpy sharedInstance] setAlertType:<#alert_type#>];

     /* (可選)如果你的應(yīng)用只在某些國家或地區(qū)可用晌该，你必須使用兩個字符的country code來設(shè)置應(yīng)用的可用區(qū)域 */
    [[Harpy sharedInstance] setCountryCode:@"<#country_code#>"];

    /* (可選) 強制指定應(yīng)用顯示語言, 請使用 Harpy.h 中定義的 HarpyLanguage 進行設(shè)置肥荔。*/
    [[Harpy sharedInstance] setForceLanguageLocalization:<#HarpyLanguageConstant#>];

    // 執(zhí)行版本檢測
    [[Harpy sharedInstance] checkVersion];
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{

    /*
        執(zhí)行每天檢測你的app是否需要更新版本绿渣，需要在`applicationDidBecomeActive:`執(zhí)行最合適
        因為這對于的你的應(yīng)用進如后臺很長時間后非常有用。
        
        同時燕耿，也會在應(yīng)用第一次啟動時執(zhí)行版本檢測
    */
    [[Harpy sharedInstance] checkVersionDaily];

    /*
        執(zhí)行每周檢測你的app新版本中符。同理需要將此代碼放置在`applicationDidBecomeActive:`中執(zhí)行。

        同時誉帅，也會在應(yīng)用第一次啟動時執(zhí)行版本檢測
     */
    [[Harpy sharedInstance] checkVersionWeekly];

}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    /*
     執(zhí)行app新版本檢測淀散，放在此是為了讓用戶從App Sore跳轉(zhuǎn)回來并重新從后臺進入你的
     app，并且沒有在從App Store中跳轉(zhuǎn)回來之前更新他們app的時候調(diào)用
     
     注意：只有當你使用*HarpyAlertTypeForce*樣式彈框類型是才使用這種方法

    并且會在你第一次啟動應(yīng)用時檢測蚜锨。
    */
    [[Harpy sharedInstance] checkVersion];
}

至此設(shè)置全部完成档插！

為不同的升級類型設(shè)置彈窗樣式

如果你喜歡為不同的升級類型比如修改(revision)，補丁(patch)亚再，輕微改動(minor)郭膛，重大修改(major)等升級類型僅僅添加下面的幾行可選代碼即可，添加位置必須在調(diào)用版本檢查的方法（checkVersion）之前

    /* 默認情況下Harpy會設(shè)置所有的版本升級樣式為HarpyAlertTypeOption */
    [[Harpy sharedInstance] setPatchUpdateAlertType:<#alert_type#>];
    [[Harpy sharedInstance] setMinorUpdateAlertType:<#alert_type#>];
    [[Harpy sharedInstance] setMajorUpdateAlertType:<#alert_type#>];
    [[Harpy sharedInstance] setRevisionUpdateAlertType:<#alert_type#>];

可選的代理和代理方法

如果你想要個處理或者追蹤終端用戶的的行為氛悬，Harpy會為你提供四個代理方法進行監(jiān)控

    // 用戶界面展示升級提示對話框
    - (void)harpyDidShowUpdateDialog;

    // 用戶已經(jīng)點擊升級按鈕并且進入到App Sotore
    - (void)harpyUserDidLaunchAppStore;

    // 用戶已經(jīng)點擊跳過此次版本更新
    - (void)harpyUserDidSkipVersion;

    // 用戶已經(jīng)點擊取消更行對話框
    - (void)harpyUserDidCancel;

If you would like to use your own UI, please use the following delegate method to obtain the localized update message if a new version is available:
如果你想使用自己的UI则剃，如果有可用的新版本，使用下面的代理來獲得本地化的升級信息（需要設(shè)置AlertTpye為HarpyAlertTypeNone）

- (void)harpyDidDetectNewVersionWithoutAlert:(NSString *)message;

強制本地化

Harpy 已經(jīng)本地化了的語言包括 Arabic, Basque, 簡體中文, 繁體中文, Danish, Dutch, English, Estonian, French, German, Hebrew, Hungarian, Italian, Japanese, Korean, Latvian, Lithuanian, Malay, Polish, Portuguese (Brazil), Portuguese (Portugal), Russian, Slovenian, Swedish, Spanish, Thai, and Turkish.

你可能想要你的升級對話框永遠顯示正確的語言圆雁，而忽略iOS的語言設(shè)置（比如在指定國家發(fā)行的app）

你可以使用以下代碼實現(xiàn)強制本地化

[[Harpy sharedInstance] setForceLanguageLocalization<#HarpyLanguageConstant#>];

在App Store上提交的重要注意事項

App Store 審核人員將不會看到升級彈框

English：

Harpy（Compatible version Base On ArtSabintsev/Harpy v3.4.5）

Notify users when a new version of your app is available, and prompt them with the App Store link.

About

Harpy checks a user's currently installed version of your iOS app against the version that is currently available in the App Store. If a new version is available, an alert can be presented to the user informing them of the newer version, and giving them the option to update the application.

Harpy is built to work with the [http://www.semver.org](Semantic Versioning) system.

• Semantic Versioning is a three number versioning system (e.g., 1.0.0)
• Harpy also supports two-number versioning (e.g., 1.0)
• Harpy also supports four-number versioning (e.g., 1.0.0.0)

Swift Support

• not support yet

Features

• [x] Three types of alerts (see Screenshots & Alert Types)
• [x] Optional delegate methods (see Optional Delegate section)
• [x] Localized for 20+ languages

Screenshots

• The left picture forces the user to update the app.
• The center picture gives the user the option to update the app.
• The right picture gives the user the option to skip the current update.
• These options are controlled by the HarpyAlertType typede that is found in Harpy.h.

Installation Instructions

Manual Installation

Copy the 'Harpy' folder into your Xcode project. It contains the Harpy.h and Harpy.m files.

Setup

1. Import Harpy.h into your AppDelegate or Pre-Compiler Header (.pch)
2. In your AppDelegate, set the appID, and optionally, you can set the alertType.
3. In your AppDelegate, call only one of the checkVersion methods, as all three perform a check on your application's first launch. Use either:
   • checkVersion in application:didFinishLaunchingWithOptions:
   • checkVersionDaily in applicationDidBecomeActive:.
   • checkVersionWeekly in applicationDidBecomeActive:.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    // Present Window before calling Harpy
    [self.window makeKeyAndVisible];

    // Set the App ID for your app
    [[Harpy sharedInstance] setAppID:@"<#app_id#>"];

    // Set the UIViewController that will present an instance of UIAlertController
    [[Harpy sharedInstance] setPresentingViewController:_window.rootViewController];

  // (Optional) Set the Delegate to track what a user clicked on, or to use a custom UI to present your message.
      [[Harpy sharedInstance] setDelegate:self];

    // (Optional) The tintColor for the alertController
    [[Harpy sharedInstance] setAlertControllerTintColor:@"<#alert_controller_tint_color#>"];

    // (Optional) Set the App Name for your app
    [[Harpy sharedInstance] setAppName:@"<#app_name#>"];

    /* (Optional) Set the Alert Type for your app
     By default, Harpy is configured to use HarpyAlertTypeOption */
    [[Harpy sharedInstance] setAlertType:<#alert_type#>];

    /* (Optional) If your application is not available in the U.S. App Store, you must specify the two-letter
     country code for the region in which your applicaiton is available. */
    [[Harpy sharedInstance] setCountryCode:@"<#country_code#>"];

    /* (Optional) Overrides system language to predefined language.
     Please use the HarpyLanguage constants defined in Harpy.h. */
    [[Harpy sharedInstance] setForceLanguageLocalization:<#HarpyLanguageConstant#>];

    // Perform check for new version of your app
    [[Harpy sharedInstance] checkVersion];
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{

    /*
     Perform daily check for new version of your app
     Useful if user returns to you app from background after extended period of time
     Place in applicationDidBecomeActive:

     Also, performs version check on first launch.
    */
    [[Harpy sharedInstance] checkVersionDaily];

    /*
     Perform weekly check for new version of your app
     Useful if you user returns to your app from background after extended period of time
     Place in applicationDidBecomeActive:

     Also, performs version check on first launch.
     */
    [[Harpy sharedInstance] checkVersionWeekly];

}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    /*
     Perform check for new version of your app
     Useful if user returns to you app from background after being sent tot he App Store,
     but doesn't update their app before coming back to your app.

     ONLY USE THIS IF YOU ARE USING *HarpyAlertTypeForce*

     Also, performs version check on first launch.
    */
    [[Harpy sharedInstance] checkVersion];
}

And you're all set!

Differentiated Alerts for Patch, Minor, and Major Updates

If you would like to set a different type of alert for revision, patch, minor, and/or major updates, simply add one or all of the following optional lines to your setup before calling any of the checkVersion methods:

    /* By default, Harpy is configured to use HarpyAlertTypeOption for all version updates */
    [[Harpy sharedInstance] setPatchUpdateAlertType:<#alert_type#>];
    [[Harpy sharedInstance] setMinorUpdateAlertType:<#alert_type#>];
    [[Harpy sharedInstance] setMajorUpdateAlertType:<#alert_type#>];
    [[Harpy sharedInstance] setRevisionUpdateAlertType:<#alert_type#>];

Optional Delegate and Delegate Methods

If you'd like to handle or track the end-user's behavior, four delegate methods have been made available to you:

    // User presented with update dialog
    - (void)harpyDidShowUpdateDialog;

    // User did click on button that launched App Store.app
    - (void)harpyUserDidLaunchAppStore;

    // User did click on button that skips version update
    - (void)harpyUserDidSkipVersion;

    // User did click on button that cancels update dialog
    - (void)harpyUserDidCancel;

If you would like to use your own UI, please use the following delegate method to obtain the localized update message if a new version is available:

- (void)harpyDidDetectNewVersionWithoutAlert:(NSString *)message;

Force Localization

Harpy has localizations for Arabic, Basque, Chinese (Simplified), Chinese (Traditional), Danish, Dutch, English, Estonian, French, German, Hebrew, Hungarian, Italian, Japanese, Korean, Latvian, Lithuanian, Malay, Polish, Portuguese (Brazil), Portuguese (Portugal), Russian, Slovenian, Swedish, Spanish, Thai, and Turkish.

You may want the update dialog to always appear in a certain language, ignoring iOS's language setting (e.g. apps released in a specific country).

You can enable it like this:

[[Harpy sharedInstance] setForceLanguageLocalization<#HarpyLanguageConstant#>];

Important Note on App Store Submissions

The App Store reviewer will not see the alert.
