Answer 1

If you want to go to the native app of Facebook in iOS.
Using delegate method of alertView
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex == 1) {
NSURL *url = [NSURL URLWithString:#"fb://profile"];
if ([[UIApplication sharedApplication] canOpenURL:url]) { //USE FB NATIVE APP
[[UIApplication sharedApplication] openURL:url];
}
else { //IF THE DEVICE IS UNABLE TO OPEN IN NATIVE APP, USE BROWSER INSTEAD
NSURL *browserURL = [NSURL URLWithString:#"http://www.facebook.com"];
[[UIApplication sharedApplication] openURL:browserURL];
}
}
}

Make sure you have added UIAlertViewDelegate in .h file
-(IBAction)btContinueClick:(id)sender{
if(Level == [list count]){
UIAlertView *info = [[UIAlertView alloc]initWithTitle:#"Good" message:#"Go to facebook?" delegate:self cancelButtonTitle:#"NO" otherButtonTitles:#"Facebook"];
[info show]; //// Change Game End Message
info.delegate=self;
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
if(buttonIndex==1)
{
NSLog(#"Facebook selected.");
NSURL *url = [NSURL URLWithString:#"fb://profile/<id>"]; // provide the app ID
[[UIApplication sharedApplication] openURL:url];
}
}
