Ho do I get to know whether specific app is installed on user device?

My goal is to create custom UIActivities for Google+, Pinterest and LinkedIn for social share. And my custom activities should appear in UIActivityViewController only if native apps are absent (aren't installed - means native share won't appear in UIActivityViewController).

But I don't know how to check whether these apps are installed Is there any possibilities for this?

Solution

  • You have to know the URL Scheme to access the app by canOpenURL like:

    NSURL *likedInURL = [NSURL URLWithString:@"linkedin://profile?id=[id]"];
if ([[UIApplication sharedApplication] canOpenURL: likedInURL]) {
    [[UIApplication sharedApplication] openURL: likedInURL];
} else {
    // There is no app installed
}

    I hope this can help you.
