Storyboard TableViewController vs coded TableViewController cells - ios

Question

I'm pretty new to iOS dev so please bear with me.
I created a simple app that had a TabBarController with 2 items. The first item was a TableViewController with some cells and the 2nd item was a simple UIView with a picture and some text. Everything worked just fine in the simulator. This was all done programmatically (did not use storyboard)
I wanted to practice using the storyboard so I decided to try and replicate the original program I made using a storyboard. The problem arises when created a TableViewController. It's asking me to specify a "reuse identifier" , at first I tried naming them all "cell" but it said I couldn't use the same identifier, so then I set the first one to "cell1" and the next to "cell2" and so on.. I didn't have to do this when I wrote the app with just code, so why now?
My coded TableViewController looks like:
#implementation FeedTableViewController
- (id)init //constructor
{
self = [super init];
if (self)
{
self.title = #"Feed";
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return 10;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Title"];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Title"];
}
cell.textLabel.text = [NSString stringWithFormat:#"%li", indexPath.row];
return cell;
}
in the last method
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
I just named them all "title" and it ran fine.
Thanks in advance for the help
