At a minimum, you need to implement tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath in your view controller. This tells the table how many rows to expect and what each row in the table looks like. The simple code below assumes you have an array of strings and are just displaying one string per cell and should get you started. Your specific situation sounds like it may require a custom cell design. This tutorial describes how to do this in a storyboard with a custom cell class.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [array count]; //tell the UITableView how many are items are in the array
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
//stuff to make sure iOS is reusing cells rather than creating new ones
static NSString *MyIdentifier = #"MyReuseIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier];
}
NSString *itemFromArray = [array objectAtIndex:indexPath.row]; //get the item for that cell
cell.textLabel.text = itemFromArray; set the cell to display the text
return cell;
}
