Putting my JSON into a tableView - iphone

Question

what i'm currently trying to do is get my json information (twitter user timeline) and stick it into a table, everything about it json works, but when it comes to adding the information to the tableView it doesn't do anything about it, Here is my code :
#import "FirstViewController.h"
#import <Twitter/Twitter.h>
#import <Accounts/Accounts.h>
#interface FirstViewController ()
- (void)fetchData;
#end
#implementation FirstViewController
#synthesize timelineTwiter = _timelineTwiter;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = NSLocalizedString(#"First", #"First");
self.tabBarItem.image = [UIImage imageNamed:#"first"];
}
return self;
}
-(void)fetchData {
ACAccountStore *store = [[ACAccountStore alloc] init];
ACAccountType *twitterAccountType =
[store accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[store requestAccessToAccountsWithType:twitterAccountType
withCompletionHandler:^(BOOL granted, NSError *error) {
if (!granted) {
NSLog(#"User rejected access to his account.");
}
else {
NSArray *twitterAccounts =
[store accountsWithAccountType:twitterAccountType];
if ([twitterAccounts count] > 0) {
ACAccount *account = [twitterAccounts objectAtIndex:0];
NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
[params setObject:#"1" forKey:#"include_entities"];
NSURL *url =
[NSURL
URLWithString:#"http://api.twitter.com/1/statuses/home_timeline.json"];
TWRequest *request =
[[TWRequest alloc] initWithURL:url
parameters:params
requestMethod:TWRequestMethodGET];
[request setAccount:account];
[request performRequestWithHandler:
^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
if (!responseData) {
NSLog(#"%#", error);
}
else {
NSError *jsonError;
NSArray *timeline = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&jsonError];
self.timelineTwiter = timeline;
if (timeline) {
NSDictionary* tweets0 = [timeline objectAtIndex:0];
NSLog(#"%#", [tweets0 objectForKey:#"text"]);
NSLog(#"%#", [[tweets0 objectForKey:#"user"] objectForKey:#"screen_name"]);
NSDictionary* tweets1 = [timeline objectAtIndex:1];
NSLog(#"%#", [tweets1 objectForKey:#"text"]);
NSLog(#"%#", [[tweets1 objectForKey:#"user"] objectForKey:#"screen_name"]);
NSDictionary* tweets2 = [timeline objectAtIndex:2];
NSLog(#"%#", [tweets2 objectForKey:#"text"]);
NSLog(#"%#", [[tweets2 objectForKey:#"user"] objectForKey:#"screen_name"]);
}
else {
NSLog(#"%#", jsonError);
}
}
}];
}
}
}];
}
-(IBAction)refreshTimeline:(id)sender {
[self fetchData];
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 0;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.timelineTwiter count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
id userTimeline = [self.timelineTwiter objectAtIndex:[indexPath row]];
cell.textLabel.text = [userTimeline objectForKey:#"text"];
cell.detailTextLabel.text = [userTimeline valueForKeyPath:#"user.name"];
return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self fetchData];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewWillAppear:(BOOL)animated
{
[self fetchData];
[super viewWillAppear:animated];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
#end
but it never loads the data into the table view, any help?
Side note:
I am using it with interface builder.
& Ideally i'd like to make a custom cell so i could work out the layout each cell, so if you know of any good sites which will show how to do that, that'd also be a big hand.

Answer 1

you have to return at least one section to the table at a minimum. right now you are return zero sections.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 0;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}

Answer 2

You missed the reloadData at the end of your fetchData implementation.
