Cannot get data for the twitter timeline - ios

Question

I am trying to load the tweets through json since I am currently making an twitter app. No sign of getting data from json twitter. I also have an null output from my array as well. Is there a possible mistake that I made using the API?
-(void)twitterTimeLine{
ACAccountStore *account = [[ACAccountStore alloc]init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[account requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error)
{
if (granted == YES) {
NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];
if ([arrayOfAccounts count] > 0) {
ACAccountType *twitterAccount = [arrayOfAccounts lastObject];
NSURL *requestAPI = [NSURL URLWithString:#"https://api.twitter.com/1.1/statuses/home_timeline/json"];
NSMutableDictionary *parameters = [[NSMutableDictionary alloc]init];
[parameters setObject:#"100" forKey:#"count"];
[parameters setObject:#"1" forKey:#"include_entities"];
SLRequest *posts = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:requestAPI parameters:parameters];
posts.account = (ACAccount *)twitterAccount;
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
[posts performRequestWithHandler:^(NSData *response, NSHTTPURLResponse *urlResponse, NSError *error){
array=[NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];
// NSLog(#"%#",posts);
NSLog(#"%#",array);
NSLog(#"---------");
if (array.count !=0) {
dispatch_async(dispatch_get_main_queue(),^{
[timelineTableView reloadData];
});
}
}];
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}
else {
NSLog(#"%#", [error localizedDescription]);
}
};
}];

Try this :
ACAccount *twitterAccount = [arrayOfAccounts lastObject];
This might be the reason of getting warning.
Update your URL with :
https://api.twitter.com/1.1/statuses/home_timeline.json
