check app version using deep linking in iOS

Question

How can we check current installed version of our app using deep linking in iOS, so that we can prompt user to upgrade the app. From safari browser, I want to navigate to app. But as per requirement, I need to check installed version of the app. If previous version is installed, we need to prompt user to update the app.

i guess you can do it in the app itself, and you check the version in : - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(nullable NSString *)sourceApplication annotation:(id)annotation so that you open the application first — Mejdi Lassidi, Jan 25 '16 at 10:33
The Appstore app updates the App automatically now so if the user has disabled this feature then they probably know about the fact that their apps are not being updated. — jAmi, Jan 25 '16 at 10:43
I think this can only be done in app side instead of the safari side. Or you can tried to set a share cookies in the app storing the version info, then read it in js. — xi.lin, Jan 25 '16 at 10:59

you can get as

The value you set in the Xcode target summary's "Version" field is in here:

ObjC

NSString *Currentversion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

To get the build number as a NSString variable:

NSString * CurrentbuildNo = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

For Example

You could probably do like this:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{

    NSString* appIDe = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleIdentifier"]; 
    NSURL* getpath = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/lookup?bundleId=%@", appIDe]];
    NSData* JSONdata = [NSData dataWithContentsOfURL:getpath];
    NSDictionary* JSonDiCt = [NSJSONSerialization JSONObjectWithData:JSONdata options:0 error:nil];

    if ([JSonDiCt[@"resultCount"] integerValue] == 1){
        NSString* currentappStoreVersion = JSonDiCt[@"results"][0][@"version"];
        NSString* currentVersiononApp = infoDictionary[@"CFBundleShortVersionString"];
        if (![currentappStoreVersion isEqualToString:currentVersiononApp]){
            NSLog(@"Need to update");
            return YES;
        }else
        {

          //Continue your Work
  }
    }

    return YES;;
}
