Making Profile Photos show up using Twitter API 1.1 - ios

Question

We're working on an iOS 7 Twitter client. I haven't worked with the the Twitter API much and what I did was before 1.1.
Could somebody please help us get the profile photos loading on our application's Timeline?
Our code is below.
Here is our .h file:
#import <UIKit/UIKit.h>
#import <Accounts/Accounts.h>
#import <Social/Social.h>
#import <Twitter/Twitter.h>
#interface FirstViewController : UIViewController <UITableViewDataSource , UITableViewDelegate> {
UIRefreshControl *myRefreshControl;
}
#property (nonatomic) IBOutlet UITableView *timelineTableView;
#property (nonatomic) NSArray *timelineArray;
#end
and here is our .m for the application's timeline.
#interface FirstViewController ()
#end
#implementation FirstViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self getTimeline];
myRefreshControl = [[UIRefreshControl alloc]init];
myRefreshControl.tintColor = [UIColor blackColor];
[myRefreshControl setAttributedTitle:[[NSAttributedString alloc]initWithString:#"Pull to Refresh"]];
[myRefreshControl addTarget:self action:#selector(refreshTimeline) forControlEvents: UIControlEventValueChanged];
[self.timelineTableView addSubview:myRefreshControl];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)getTimeline
{
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)
{
ACAccount *twitterAccount = [arrayOfAccounts lastObject];
NSURL *requestURL = [NSURL URLWithString:#"http://api.twitter.com/1/statuses/home_timeline.json"];
NSMutableDictionary *parameters =
[[NSMutableDictionary alloc] init];
[parameters setObject:#"200" forKey:#"count"];
[parameters setObject:#"1" forKey:#"include_entities"];
SLRequest *postRequest = [SLRequest
requestForServiceType:SLServiceTypeTwitter
requestMethod:SLRequestMethodGET
URL:requestURL parameters:parameters];
postRequest.account = twitterAccount;
[postRequest performRequestWithHandler:
^(NSData *responseData, NSHTTPURLResponse
*urlResponse, NSError *error)
{
self.timelineArray = [NSJSONSerialization
JSONObjectWithData:responseData
options:NSJSONReadingMutableLeaves
error:&error];
if (self.timelineArray.count != 0) {
dispatch_async(dispatch_get_main_queue(), ^{
[self.timelineTableView reloadData];
});
}
}];
}
} else {
}
}];
}
-(void)refreshTimeline
{
[self getTimeline];
[self.timelineTableView reloadData];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.timelineArray count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSDictionary *tweet = self.timelineArray[[indexPath row]];
cell.textLabel.text = [[tweet objectForKey:#"user"]objectForKey:#"name"];
cell.detailTextLabel.text = [tweet objectForKey:#"text"];
cell.imageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL: [[tweet objectForKey:#"user"]objectForKey:#"profile_image_url"]]];
return cell;
}
#end

Answer 1

The response of :
http://api.twitter.com/1/statuses/home_timeline.json
will return home feeds. It contains a user key in it , you have to access that and get the profile image by profile_image_url.
Handling response in array of dictionaries will solve your problem and each dictionary will have the user key which contains profile_image_url.

Answer 2

Your call to the api is referencing version 1. I would suggest reviewing the info at https://dev.twitter.com/docs/api/1.1/get/statuses/home_timeline and examining the response format.
You can drill down the response to arrive at the 'user' object and get the profile image from there.
