How I can get news feed in the table view ?

Answer 1

Page Number is missing in your url &pageno=1.
Your url looks like this:
http://api.shoclef.com/api/NewsFeed?user_id=1164
It should be like this:
http://api.shoclef.com/api/NewsFeed?user_id=1164&pageno=1
try this in you API Manager class. Working fine for me.
NSString * url = [NSString stringWithFormat:#"%#NewsFeed?user_id=%I&pageno=1",API_BASE_URL,userID];
Update For Image
Update this code in your cellForRowAtIndexPath function in NewsFeedNew class
NSString *strUrl = [self.images objectAtIndex:indexPath.row].image;
strUrl = [strUrl stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
[cell.image sd_setImageWithURL:[NSURL URLWithString:strUrl]];

Answer 2

You need to set tableview delegate and dataSource.
Also put a break point in numberOfRowsInSection method to verify that tableview is set with datasource and delegate.

Answer 3

You need to reload data of tableview when you get response - [self.tableView reloadData];
-(void)getBuyerSocialPage {
NSLog(#"getBuyerSocialPage");
UserDao * profileID = [[DatabaseManager sharedManager]getLoggedInUser];
ApiManager * manager = [ApiManager sharedManager];
[manager socialPageWithProfileID:profileID.userID withCompletionBlock:^(BOOL error, NSDictionary *socialPage) {
// NSMutableArray * details = [[NSMutableArray alloc]init];
for (NSDictionary * temp in socialPage ) {
[self.socialPageArray addObject:temp];
}
[self.tableView reloadData];
if (!error) {
self.profileImages=self.socialPageArray;
}
}];
}

Answer 4

Few things to debug here,
Your API response might be nil or having error check and log appropriate response.
If the server response is correct then get on the main thread and reload the TableView
Set the UITableViewDataSource and UITableViewDelegate to self if you haven't done in storyboard.
- (void)getBuyerSocialPage {
NSLog(#"getBuyerSocialPage");
UserDao *profileID = [[DatabaseManager sharedManager] getLoggedInUser];
ApiManager *manager = [ApiManager sharedManager];
__weak BuyerSocialPage *weakSelf = self;
[manager socialPageWithProfileID:profileID.userID withCompletionBlock:^(BOOL error, NSDictionary *socialPage) { [weak self]
if (error) {
NSLog("Error fetching data");
return;
}
for (NSDictionary *temp in socialPage ) {
[weakSelf.socialPageArray addObject:temp];
}
if ([weakSelf.socialPageArray count] > 0) {
// update UI on the main thread
dispatch_async(dispatch_get_main_queue(), ^{
weakSelf.tableView.reloadData()
}
}
}]
}
