More cells in TableView - iphone

Question

I have a tableview that I am populating with JSON, but it is doubling the values that I have. I only have 2 objects, but it is putting 4 in the tableview. Can someone tell me what I am doing wrong and why I am listing 4 objects when there are only 2? I have checked the count and the data model and they both only show 2 items.
Here is my code:

I believe this is why...
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
rootList =[[GlobalData sharedData].mRootBeers getRootBeers];
NSLog(#"RootList: %#", rootList);
// Return the number of sections.
NSLog(#"RootList count: %i", rootList.count);
return rootList.count;
}
change it to this.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
You are adding a section for each object in rootList, and then adding all of rootlist in each section. So returning only one section is easiest.
