iOS迭代版本 (转)

当前运行版本信息可以通过info.plist文件中的bundle version中获取：[cpp] view plaincopyNSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];      CFShow(infoDic);      NSString *appVersion = [infoDic objectForKey:@"CFBundleVersion"];  这样就获取到当前运行的app的版本了要获取当前app store上的最新的版本，有两种方法，一、在某特定的服务器上，发布和存储app最新的版本信息，需要的时候向该服务器请求查询。二、从app store上查询，可以获取到app的作者，连接，版本等。官方相关文档www.apple.com/itunes/affiliates/resources/documentation/itunes-store-web-service-search-api.htm具体步骤如下：1，用 POST 方式发送请求：http://itunes.apple.com/search?term=你的应用程序名称&entity=software更加精准的做法是根据 app 的 id 来查找：http://itunes.apple.com/lookup?id=你的应用程序的ID#define APP_URL http://itunes.apple.com/lookup?id=你的应用程序的ID你的应用程序的ID 是 itunes connect里的 Apple ID2，从获得的 response 数据中解析需要的数据。因为从 appstore 查询得到的信息是 JSON 格式的，所以需要经过解析。解析之后得到的原始数据就是如下这个样子的：{      resultCount = 1;      results =     (                  {              artistId = 开发者 ID;              artistName = 开发者名称;             price = 0;             isGameCenterEnabled = 0;              kind = software;              languageCodesISO2A =             (                  EN              );             trackCensoredName = 审查名称;              trackContentRating = 评级;              trackId = 应用程序 ID;              trackName = 应用程序名称";              trackViewUrl = 应用程序介绍网址;              userRatingCount = 用户评级;              userRatingCountForCurrentVersion = 1;              version = 版本号;              wrapperType = software;       }      );  }  然后从中取得 results 数组即可，具体代码如下所示：NSDictionary *jsonData = [dataPayload JSONValue];  NSArray *infoArray = [jsonData objectForKey:@"results"];  NSDictionary *releaseInfo = [infoArray objectAtIndex:0];  NSString *latestVersion = [releaseInfo objectForKey:@"version"];  NSString *trackViewUrl = [releaseInfo objectForKey:@"trackViewUrl"];  如果你拷贝 trackViewUrl 的实际地址，然后在浏览器中打开，就会打开你的应用程序在 appstore 中的介绍页面。当然我们也可以在代码中调用 safari 来打开它。UIApplication *application = [UIApplication sharedApplication];  [application openURL:[NSURL URLWithString:trackViewUrl]];  代码如下：-(void)onCheckVersion{    NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];    //CFShow((__bridge CFTypeRef)(infoDic));    NSString *currentVersion = [infoDic objectForKey:@"CFBundleVersion"];    NSString *URL = @"http://itunes.apple.com/lookup?id=你的应用程序的ID";    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];    [request setURL:[NSURL URLWithString:URL]];    [request setHTTPMethod:@"POST"];    NSHTTPURLResponse *urlResponse = nil;    NSError *error = nil;    NSData *recervedData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponseerror:&error];    NSString *results = [[NSString alloc] initWithBytes:[recervedData bytes] length:[recervedData length]encoding:NSUTF8StringEncoding];    NSDictionary *dic = [results JSONValue];    NSArray *infoArray = [dic objectForKey:@"results"];    if ([infoArray count]) {        NSDictionary *releaseInfo = [infoArray objectAtIndex:0];        NSString *lastVersion = [releaseInfo objectForKey:@"version"];        if (![lastVersion isEqualToString:currentVersion]) {            //trackViewURL = [releaseInfo objectForKey:@"trackVireUrl"];            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"更新" message:@"有新的版本更新，是否前往更新？" delegate:self cancelButtonTitle:@"关闭" otherButtonTitles:@"更新", nil];            alert.tag = 10000;            [alert show];        }        else        {            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"更新" message:@"此版本为最新版本"delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];            alert.tag = 10001;            [alert show];        }    }}- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{    if (alertView.tag==10000) {        if (buttonIndex==1) {            NSURL *url = [NSURL URLWithString:@"https://itunes.apple.com"];            [[UIApplication sharedApplication]openURL:url];        }    }}
