Update reminder and score reminder for iphone/ipad apps

When you use an iphone/ipad app, sometimes the app has an update and upgrade. The appstore will remind you of the corresponding updates. In the app, you need to remind the user of the updates when opening the app, in this case, you need to write a reminder in the program. The resume pop-up box reminds the user of this issue and it will be OK!

The specific code is shared with you. Please note that you must have the app id. So what do you do if the app has no id for the first time? When the review is launched, you will get the id, and then you can enter the id directly.

First, write a singleton class:

/// AppUpdateGrade. m // QingDaoBroadcastIpad /// Created by iHope on 13-7-23. // Copyright (c) 2013 hlren. all rights reserved. // # import "AppUpdateGrade. h "@ implementation AppUpdateGradestatic AppUpdateGrade * appUpdateGrade = nil; + (AppUpdateGrade *) sharedAppupdateGrade {@ synchronized (self) {if (appUpdateGrade = nil) {appUpdateGrade = [[self alloc] init] ;}return appUpdateGrade ;}// update and upgrade-(void) app Update :( NSString *) appleID {appId = appleID; // http://itunes.apple.com/lookup?

1. update and upgrade

You need to get the version of the current application and the version of the previous version. In comparison, do you need to update the version!

Current application version:

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

Previous application version:

Need to request http://itunes.apple.com/lookup? Id = appid to obtain data and analyze the version;

2. Application rating

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

You can directly open this link to grade the application;

 
 

Use, import # import "AppUpdateGrade. h"

 

Upgrade [[AppUpdateGrade sharedAppupdateGrade] appUpdate: @ "appid"]; // score afterDelay seconds 60*1 = 60 Minutes, indicating that the pinfen method is called one minute later [self defined mselector: @ selector (pinfen) withObject: self afterDelay: 1]; // upgrade [[AppUpdateGrade sharedAppupdateGrade] appUpdate: @ "appid"]; // score afterDelay seconds 60*1 = 60 Minutes, indicating that the pinfen method is called one minute later [self defined mselector: @ selector (pinfen) withObject: self afterDelay: 1];

 

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