ios开发检测新版本

检测新版本，无需appID，只需要项目的bundleID就可以了

直接贴代码：

#define APPSTOREURL @"https://itunes.apple.com/lookup?bundleId="

- (NSDictionary *)checkVersion{

    NSDictionary *infoDic = [[NSBundlemainBundle] infoDictionary];

    

    NSError *error;

    NSString *urlStr = [NSStringstringWithFormat:@"%@%@",APPSTOREURL,infoDic[@"CFBundleIdentifier"]];

    NSLog(@"urlStr === %@",urlStr);

    NSURLRequest *request = [NSURLRequestrequestWithURL:[NSURLURLWithString:urlStr]];

    NSData *response = [NSURLConnectionsendSynchronousRequest:request returningResponse:nilerror:nil];

    NSDictionary *appInfo = [NSJSONSerializationJSONObjectWithData:response options:NSJSONReadingMutableLeaveserror:&error];

    NSLog(@"appInfo === %@",appInfo);

    

    if (error) {

        NSLog(@"%@",error.description);

        return nil;

    }

    

    NSArray *resultArray = [appInfo objectForKey:@"results"];

    

    if (![resultArray count]) {

        NSLog(@"error:resultArray == nil");

        return nil;

    }

    //AppStore上的版本号

    NSDictionary *infoDict = [resultArray firstObject];

    //最新版本号

    NSString *appVersion = infoDict[@"version"];

    //名称

    NSString *trackName = infoDict[@"trackName"];

    //新包大小

    NSString *fileSizeBytes = infoDict[@"fileSizeBytes"];

    //渠道链接

    self.trackUrl = infoDict[@"trackViewUrl"];

    //新版本发布时间

    NSString *currentVersionReleaseDate = infoDict[@"currentVersionReleaseDate"];

    //新版本价格

    NSString *price = infoDict[@"price"];

    //新版本发布说明

    NSString *releaseNotes = infoDict[@"releaseNotes"];

    //最低支持系统

    NSString *minimumOsVersion = infoDict[@"minimumOsVersion"];

    //版本类型

    NSString *kind = infoDict[@"kind"];

    //渠道id

    NSString *trackID = infoDict[@"trackId"];

    

    //调接口，显示这个版本是否强制更新，调用你自己的接口，平台给吧

    NSString *upgradeUrl = [NSStringstringWithFormat:@""];

    

    NSURLRequest *upgradeRequest = [NSURLRequestrequestWithURL:[NSURLURLWithString:upgradeUrl]];

    NSData *responseData = [NSURLConnectionsendSynchronousRequest:upgradeRequest returningResponse:nilerror:nil];

    NSDictionary *upgradeDict = [NSJSONSerializationJSONObjectWithData:responseData options:NSJSONReadingMutableLeaveserror:&error];

//    NSLog(@"upgradeDict == %@",upgradeDict);

    

    //获取当前软件版本

    NSString *nowVersion = infoDic[@"CFBundleShortVersionString"];

    

    //判断是否需要更新，

    NSString *isUpgrade;

    if (![appVersion isEqualToString:nowVersion]) {

        isUpgrade = @"1";

    }else{

        isUpgrade = @"0";

    }

    

    NSDictionary *backDict = @{@"isUpgrade":isUpgrade,

                               @"isForcedUpgrade":upgradeDict[@"isForcedUpgrade"],

                               @"appversion":appVersion,

                               @"trackname":trackName,

                               @"fileSizeBytes":fileSizeBytes,

                               @"trackurl":self.trackUrl,

                               @"currentVersionReleaseDate":currentVersionReleaseDate,

                               @"price":price,

                               @"releaseNotes":releaseNotes,

                               @"minimumOsVersion":minimumOsVersion,

                               @"kind":kind,

                               @"trackID":trackID};

    

    return backDict;
