Twitter integration through SLComposeViewController in iPhone - ios

Question

I am using SLComposeViewController to share the images on twitter. If i am not logged-in via iPhone settings than i want to show alert view. Please any body will suggest what to do.

Answer 1

Use this code:
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
//show compose view
else
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Not available"
message:#"Twitter is not available."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];

Answer 2

Using ACAccountStore and ACAccount you can Check weather you have login or not.
Refer the sample code here: How to post on twitter by hiding SLComposeViewController *tweetSheettweet instance

Answer 3

Declare in .h file
#property (strong, nonatomic) ACAccount *fbAccount;
#property (strong, nonatomic) NSString *slService;
#property (strong, nonatomic) ACAccountStore *accountStore;
Add in .m file
- (IBAction)TwittButtonPressed:(id)sender
{
if(!accountStore)
accountStore = [[ACAccountStore alloc] init];
ACAccountType *twitterAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
// Request access to the Twitter account with the access info
[self.accountStore requestAccessToAccountsWithType:twitterAccountType options:nil completion:^(BOOL granted, NSError *error) {
if (granted) {
// If access granted, then get the Twitter account info
NSArray *accounts = [self.accountStore accountsWithAccountType:twitterAccountType];
if (accounts.count>0) {
self.fbAccount=[accounts lastObject];
//NSLog(#"Twitter account Details =%#",self.fbAccount);
self.fbAccount=[accounts objectAtIndex:0];
NSString *username1 = self.fbAccount.username;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setValue:username1 forKey:#"twitUserName"];
[defaults synchronize];
//NSLog(#"USer ID %#and Username%#",[defaults valueForKey:#"twitUserID"],[defaults valueForKey:#"twitUserName"]);
self.slService = SLServiceTypeTwitter;
// NSLog(#"Show indicatoer############");
[self performSelectorOnMainThread:#selector(sharingPostData:) withObject:_slService waitUntilDone:YES];
}
else{
// NSLog(#"Access not granted");
[self performSelectorOnMainThread:#selector(throwAlertWithTitle:) withObject:#"Account not found. Please setup your account in settings" waitUntilDone:NO];
}
// [self sharingPostData:self.slService];
} else {
// NSLog(#"Access not granted");
[self performSelectorOnMainThread:#selector(throwAlertWithTitle:) withObject:#"Account not found. Please setup your account in settings" waitUntilDone:NO];
}
}];
}
-(void)throwAlertWithTitle:(NSString *)message{
//remove DSActivity if any
UIAlertView *errorAlert = [[UIAlertView alloc] initWithTitle:#"Notification" message:message delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[errorAlert show];
errorAlert=nil;
}
-(void)sharingPostData:(NSString *)serviceType{
if ([SLComposeViewController isAvailableForServiceType:serviceType])
{
SLComposeViewController *fvc = [SLComposeViewController composeViewControllerForServiceType:serviceType];
[fvc setInitialText:#"Share text here"];
[fvc addImage:backGroundImage.image];
[fvc addURL:[NSURL URLWithString:kAppituneslink]];
[self presentViewController:fvc animated:YES completion:nil];
}
}
