Does anyone know how can I open the Facebook messenger application with a pre-filled text?
For example, to open the messenger app at a specified user, you can write the following:
NSURL *fbURL = [NSURL URLWithString:@"fb-messenger://user-thread/USER_ID"];
if ([[UIApplication sharedApplication] canOpenURL: fbURL]) {
[[UIApplication sharedApplication] openURL: fbURL];
}
For Whats app is very easy:
NSURL *whatsappURL = [NSURL URLWithString:[NSString stringWithFormat:@"whatsapp://send?text=%@", @"String to post here"]];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
[[UIApplication sharedApplication] openURL: whatsappURL];
}
There is such a function but it exists only in Facebook's SDK.
