How to open VK app from my ios app

Question

I want to open my public page in vk app (if it is installed). How can I manage to do that

Here's the same trick with facebook

- (IBAction)facebook:(id)sender{
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fb://profile/1425897281000202"]]){
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"fb://profile/1425897281000202"]];
        NSURL *url = [NSURL URLWithString:@"fb://profile/1425897281000202"];
        [[UIApplication sharedApplication] openURL:url];
    }
    else {
        [[UIApplication sharedApplication]
         openURL:[NSURL URLWithString:@"https://www.facebook.com/GooodApps"]];
    }
}

Thanx!

This works for me in Swift:

let appURL = NSURL(string: "vk://vk.com/id\(user.vkID)")!
let safariURL = NSURL(string: "vk.com/id\(user.vkID)")!

if UIApplication.sharedApplication().canOpenURL(appURL){
    UIApplication.sharedApplication().openURL(appURL)
} else {
    UIApplication.sharedApplication().openURL(safariURL)
}
