Use this code for Share App.
-(void)facebook
{
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
if (result == SLComposeViewControllerResultCancelled) {
NSLog(#"Cancelled");
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Congratulations!" message:#"Successfully posted to facebook Wall." delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alert show];
[Flurry logEvent:#"Share screen - Successfully posted on Facebook"];
}
[controller dismissViewControllerAnimated:YES completion:Nil];
};
controller.completionHandler =myBlock;
NSString *str=[NSString stringWithFormat:#" I am using App for my iPhone. You too can download it from here"];
[controller setInitialText:str];
[self presentViewController:controller animated:YES completion:Nil];
}
else{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Sorry!"message:#"Please add Facebook account in settings menu" delegate:self cancelButtonTitle:Nil otherButtonTitles:#"Ok", nil];
alert.tag=100;
[alert show];
}
}
For use of SLComposeViewController,you have to add Social Framework. It fetch your facebook account from setting and you can share your app link through SLComposeViewController. and
if you want to add images or URL to in than :
[composeController addImage:[UIImage imageNamed:#"image.png"]];
[composeController addURL: [NSURL URLWithString:#"apple.com"]];
