ios迭代版本，在appstore显示更新功能怎么做

Posted 2023-03-09

参考技术A 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 plaincopy
NSDictionary *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 ID
2，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];
