In the code below, a tableview displays the twitter feed of the user of the phone. All I want to do is display the feed of a user that I predefine in the code. I looked online but can't find any tutorials on this. I would like to edit this code instead of restarting with a third party API.

#import "TwitterViewController.h"
#import <Accounts/Accounts.h>

@interface TwitterViewController ()
@property (strong, nonatomic) NSArray *twitterArray;
@end
@implementation TwitterViewController

{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self twitterTimeline];
// Do any additional setup after loading the view from its nib.
}

{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

ACAccountStore *account = [[ACAccountStore alloc] init]; // Creates AccountStore object.
// Asks for the Twitter accounts configured on the device.
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[account requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error)
{
// If we have access to the Twitter accounts configured on the device we will contact the Twitter API.
if (granted == YES){
NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType]; // Retrieves an array of Twitter accounts configured on the device.
// If there is a leat one account we will contact the Twitter API.
if ([arrayOfAccounts count] > 0) {
ACAccount *twitterAccount = [arrayOfAccounts lastObject]; // Sets the last account on the device to the twitterAccount variable.
NSURL *requestAPI = [NSURL URLWithString:@"http://api.twitter.com/1.1/statuses/user_timeline.json"]; // API call that returns entires in a user's timeline.
// The requestAPI requires us to tell it how much data to return so we use a NSDictionary to set the 'count'.
NSMutableDictionary *parameters = [[NSMutableDictionary alloc] init];
[parameters setObject:@"100" forKey:@"count"];
[parameters setObject:@"1" forKey:@"include_entities"];
// This is where we are getting the data using SLRequest.
SLRequest *posts = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:requestAPI parameters:parameters];
posts.account = twitterAccount;
// The postRequest: method call now accesses the NSData object returned.
[posts performRequestWithHandler:
^(NSData *response, NSHTTPURLResponse
*urlResponse, NSError *error)
{
// The NSJSONSerialization class is then used to parse the data returned and assign it to our array.
self.twitterArray = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];
if (self.twitterArray.count != 0) {
dispatch_async(dispatch_get_main_queue(), ^{
[self.twitterFeedTable reloadData]; // Here we tell the table view to reload the data it just recieved.
});
}
}];
}
} else {
// Handle failure to get account access
NSLog(@"%@", [error localizedDescription]);
}
}];
}

The information is here in the docs.
You need to add either a user_id parameter or a screen_name parameter to your http://api.twitter.com/1.1/statuses/user_timeline.json request, and that's all.
Example as provided in the documentation:
