Open link to Facebook page from iOS app

Question

I want to redirect user to my App's Facebook page, so I have the following code:

[[UIApplication sharedApplication] openURL:
    [NSURL URLWithString: @"https://facebook.com/myAppsPage"]];

this works great, if there is no Facebook app on device. Then the link opens in Safari.

If there is Facebook app installed on device, then after executing above code Facebook app opens, but it is showing users timeline, not my app's page. I tried to change link to @"fb://pages/myAppsPage" and to @"fb://profile/myAppsPage, but this again opened users timeline.

So, my question is: how can I open my apps page in safari, if there is no Facebook app, or in Facebook app, if the one is installed.

Answer 1

You have to use the facebook ID for the given page rather than the vanity URL. To get the pages ID, enter your page's vanity name at the following URL and copy the value for "id":

https://graph.facebook.com/yourappspage

Once you have the id, you can set up the method to check if FB is installed using the canOpenURL method and serve the appropriate content for both states:

NSURL *facebookURL = [NSURL URLWithString:@"fb://profile/113810631976867"];
if ([[UIApplication sharedApplication] canOpenURL:facebookURL]) {
    [[UIApplication sharedApplication] openURL:facebookURL];
} else {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://facebook.com"]];
}
