ive read through alot of posts here on my issue, but none have worked yet, so thanks in advance for helping.
I have a tableview, that loads a custom nib. I have data coming from a web JSON file. I have implemented a refresh call (im now overriding this with just a cell tap).
Upon calling the method, the new JSON is called and parsed. And the cells updated. I can confirm this with scrolling the tableview down I can seemy new rows. But the rows that are visible remain.
Ive tried to make the array nil, cycle through and remove based on object but nothing seems to work.
here is code
#import "MMNewsViewController.h"
#import "MMCatsDetailController.h"
#import "CellView.h"
#import "FeatureCell.h"
//#import "MMnewsData.h"
@interface MMNewsViewController ()
