How to detect if Facebook app is installed on iOS?

Question

On iOS, you can launch the Facebook app and link to a profile by opening a url like this: fb://profile/12345

The only problem is that if the Facebook app isn't installed, nothing happens.

Is there a way to detect if the app is installed or if the url scheme fb:// is supported?

This would apply broadly to other apps like Twitter as well.

Solution 1

BOOL isInstalled = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fb://"]]

if (isInstalled) {

} else {

}

Solution 2

Try just using the canOpenURL: function

NSURL *fbURL = [NSURL URLWithString:@"fb://"];//or whatever url you're checking

if ([[UIApplication sharedApplication] canOpenURL:fbURL])
{
  //open it etc  
}

You also need to include LSApplicationQueriesSchemes key into info.plist for iOS 9 with value "fb".
