iphone/ipad應用的升級更新提醒和評分提醒

在使用iphone/ipad應用的時候，有時候應用有更新升級，appstore會提醒使用者有相應的更新，程式中需要在使用者開啟應用的時候提醒使用者更新，那麼就需要自己在程式當中寫一個提醒事項，簡曆彈出框提醒使用者一下，就ok了！

具體代碼分享給大家，請大家注意，必須要有app的id。那麼你會想應用第一次沒有id怎麼辦？審請上線的時候就會得到id了，到時候有了id直接填上去就行了。

首先寫一個單例類：

1、更新升級

需要得到當前應用的version版本，獲得之前版本的version，比較之下是否需要更新！

當前應用的version：

NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
        NSString *currentVersion = [infoDict objectForKey:@"CFBundleVersion"];

之前應用的version：

需要請求http://itunes.apple.com/lookup?id=appid來擷取資料，分析出version；

2、應用評分

"itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=appid“

直接開啟這個連結就可以給應用評份；

 
 

使用，匯入#import "AppUpdateGrade.h"

 

 升級      [[AppUpdateGrade sharedAppupdateGrade]appUpdate:@"appid"];     //評分  afterDelay秒  60*1==60分鐘,表示1分鐘後調用pinfen方法      [self performSelector:@selector(pinfen) withObject:self afterDelay:1]; //升級    [[AppUpdateGrade sharedAppupdateGrade]appUpdate:@"appid"];    //評分  afterDelay秒  60*1==60分鐘,表示1分鐘後調用pinfen方法    [self performSelector:@selector(pinfen) withObject:self afterDelay:1];

 

 (void)pinfen {     //評分      [[AppUpdateGrade sharedAppupdateGrade]appGrade:@"appid"]; } - (void)pinfen{    //評分    [[AppUpdateGrade sharedAppupdateGrade]appGrade:@"appid"];}
