Question

Im trying to follow a tutorial that is using SBJsonParser to get twitter feeds, and displays them in a table view.

But i am getting the following error

[__NSCFDictionary isEqualToString:]: unrecognized selector sent to instance 0x6b7e510

this is whats in my

@interface NSString *json_string; NSArray *statusArray;

This is the code im using to get the twitter feed

`SBJsonParser *parser = [[SBJsonParser alloc] init];

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://twitter.com/statuses/public_timeline.json"]];

NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];


json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];

statusArray = [parser objectWithString:json_string error:nil];`

And this is what im using to put it into a table view

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return statusArray.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];


cell.textLabel.text = [[statusArray objectAtIndex:indexPath.row] objectForKey:@"user"];

return cell;
}

EDIT:

I NSLogged statusArray with objectatindex:0 and i got

Lets assume your json parser is bug free.

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {    
        return 1
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
        return statusArray.count;
 }

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:              (NSIndexPath *)indexPath
{
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];

        //note: valueForKeyPath return nil, if key does not find
        NSString *userInfo = [[statusArray objectAtIndex:indexPath.row] valueForKeyPath:@"user.name"]; // or valueForKeyPath:@"user.screen_name"

        if ([userInfo isEqualToString=@""] || [userInfo length]<0])
            cell.textLabel.text = @"There is no user info";
        else
            cell.textLabel.text = userInfo;
      return cell;
}
