Currently, I want to check in my app whether Facebook App is installed or not.
What am I doing:
UIApplication.shared.canOpenURL(URL(string: "fb://")!)enter code here
In URL Schemes I have added fb, so not missed that part too.
But canOpenURL RETURNS TRUE
! But the app IS UNinstalled. I restarted the device, not helped. Why this is happening? UPDATE: some code
if UIApplication.shared.canOpenURL(URL(string: "fb://")!) {
self.shareToFacebook(with: completion)
} else {
progressVC.dismiss(animated: false, completion: nil)
UIApplication.shared.open(URL(string: "https://itunes.apple.com/us/app/facebook/id284882215")!)
}
SOLUTION: I found the solution people. In URL types I had been added fb45....(id of my app), and also added fb, which one shouldn't be there, I removed fb, and only kept the one with id, so the openURL now returns false if the app is not installed
You need to add fb
to the LSApplicationQueriesSchemes
array in the app plist, not the URL schemes
array, like so:
<key>LSApplicationQueriesSchemes</key>
<array>
<string>fb</string>
</array>
