I want to connect Facebook and Twitter account with my iOS app. I am looking for the code which checks if accounts is there in settings or not. If it's there it takes for login with same account and if it's not then asks user to add account in settings.
I tried couple of things but really not working. If anyone needs my code, then let me know i will post it on pastebin.

Add Twitter and Social Framework in your Project and import in your class file like
#import <Social/Social.h>
#import <Twitter/Twitter.h>
For Facebook
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
NSData *aImgdata=[[NSUserDefaults standardUserDefaults]objectForKey:#"EditImage"];
if (aImgdata) {
UIImage *aImage=[UIImage imageWithData:aImgdata];
[controller addImage:aImage];
}
controller.completionHandler = ^(SLComposeViewControllerResult result) {
if(result == SLComposeViewControllerResultDone) {
}
[self dismissViewControllerAnimated:YES completion:nil];
};
[self presentViewController:controller animated:YES completion:Nil];
}
else
{
[self ShowAlertView: #"You can't share on facebook right now, make sure your device has an internet connection and you have at least one Facebook account setup"];
}
For Twitter
if([TWTweetComposeViewController canSendTweet]) {
{
TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init];
NSData *aImgdata=[[NSUserDefaults standardUserDefaults]objectForKey:#"EditImage"];
if (aImgdata) {
UIImage *aImage=[UIImage imageWithData:aImgdata];
[tweetViewController addImage:aImage];
}
tweetViewController.completionHandler = ^(TWTweetComposeViewControllerResult result) {
if(result == TWTweetComposeViewControllerResultDone) {
[self ShowAlertView: #"Tweet Has been Shared"];
}
[[AppDelegate sharedInstance]showActivity:NO];
[self dismissViewControllerAnimated:YES completion:nil];
};
[self presentViewController:tweetViewController animated:YES completion:nil];
}
} else {
[self ShowAlertView: #"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"];
}

For Twitter

To check if you can share with Facebook or Twitter, use:
[SLComposeViewController isAvailableForServiceType:serviceType]
Where serviceType can be any of the SLServiceTypes such as, SLServiceTypeFacebook and SLServiceTypeTwitter
This will basically check if they have those services natively connected in their settings. I don't think you can ask the user to add it in their settings. Most of the time, a particular sharing option just won't show up if it is not available like on a UIActionSheet.
My guess would be that you can use the SLComposeViewController to check for a connected account and if not connected, use the appropriate SDK to connect their account with your iOS app.
