iTunes 查找 API 在我的 APP 中返回旧数据 [英] iTunes lookup API return old data in my APP

问题描述

我的 APP 通过比较 iTunes 查找 API 返回的本地版本和远程版本来检查更新.但是新版本发布后API仍然返回旧版本.

My APP check update by comparing local version and remote version returned by iTunes lookup API. But the API still return old version after new version has released.

https://itunes.apple.com/us/lookup?bundleId=com.xxx.xxxx

This API return new version(4.9) if I request through browser, but return old version(4.8.1) in APP.

Anybody help? Thanks.

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    //first check iTunes
    NSString *iTunesServiceURL = [NSString stringWithFormat:@"https://itunes.apple.com/us/lookup"];
    iTunesServiceURL = [iTunesServiceURL stringByAppendingFormat:@"?bundleId=%@", [[NSBundle mainBundle] bundleIdentifier]];
    NSLog(@"iRate is checking %@ to retrieve the App Store details...", iTunesServiceURL);

    NSError *error = nil;
    NSURLResponse *response = nil;
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:iTunesServiceURL] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];
    NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    NSInteger statusCode = ((NSHTTPURLResponse *)response).statusCode;
    if (data && statusCode == 200)
    {
        //in case error is garbage...
        error = nil;
        id json = nil;
        if ([NSJSONSerialization class])
        {
            json = [[NSJSONSerialization JSONObjectWithData:data options:(NSJSONReadingOptions)0 error:&error][@"results"] lastObject];
        }
        else
        {
            //convert to string
            json = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        }

        if (!error)
        {
            self.appStoreId = [self valueForKey:@"trackId" inJSON:json];
            self.latestVersion = [self valueForKey:@"version" inJSON:json];
            self.releaseNote = [self valueForKey:@"releaseNotes" inJSON:json];
        }
    }
    });
}

解决方案

I was also facing same issue but in my case I was using http (e.g. http://itunes.apple.com/lookup?bundleId=com.xxx.xxxx) so not getting latest app version. Then I replaced http to https (https://itunes.apple.com/lookup?bundleId=com.xxx.xxxx) after that its working for me.

Update - Our team sent mail to apple developers and ask why https is working and http is not working and got reply from apple team. He told "In general, there is a 24 hours delay for updated app information to go from App Store Connect to the public."
