iOS Creating Another Row Problem

[imfrog2002]

Okay, I didn't see anything on search, so sorry if this was posted before.

I'm trying to make a iPhone app, and I can't figure out how to get a second cell/row. I'm using the Navigation Base App template, and in the RootViewController.m file, I have the "numberOfSectionsInTableView" set to 1, and the "numberOfRowsInSection" set to 2. I can't get it to change the cell text on the second row/cell. What code in there do I need to copy/edit. I'm still new at this, so I'm mostly looking up stuff as I go. This is the only thing that I can't find online. Thanks in advance!

Can you post some code?

EDIT: Man, I've been looking at this code too long. Can a mod move this to the iPhone programming forum? Thanks. *bangs head on desk*

Do you also have cellForRowAtIndexPath implemented?

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
	return 1;
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
	return 1;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	
	static NSString *MyIdentifier = @"MyIdentifier";
	
	UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
	if (cell == nil) {
		cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
	}

	[cell setText = @"Text 1"];
	// Set up the cell
	return cell;
}

That's what it is before edits.

I was thinking that adding another cell setText line is all I needed to do (and change the numberOfRowsInSection to 2,) but I've found that's not the case.

Thanks to a very kind person, I was able to fix it! For future reference, and anybody that searches, this is what needed to happen:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
	return 2;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	
	static NSString *MyIdentifier = @"MyIdentifier";
	
	UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
	if (cell == nil) {
		cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
	}
	
	switch (indexPath.row) {
		case 0:
			cell.text = @"Database";
			break;
		case 1:
			cell.text = @"Settings";
			break;
	}

	
	// Set up the cell
	return cell;
}

Thanks again!

Thanks for posting the "fix"!
That is so helpful for those of searching for similar issues.

By the way, one thing I don't quite understand is why the identifier is always a hard coded string? Shouldn't the identifier be unique for each cell? otherwise how does it know which cell to retrieve from cache? I must be missing something obvious...

It should be unique for each -type- of cell. As long as all of your cells are the same basic type and are just populated with different data, they can all have the same ID.
