Question

I am designing a custom prototype cell with lots of labels, textfields and buttons in it.

I created a tableview controller on storyboard with a prototype cell.I have added a objective-c tableviewcontroller class. And connected them. Default code added by Xcode gives error itself.

in.h

@interface CreaatePlistTableViewController : UITableViewController<UITableViewDelegate, UITableViewDataSource>

in.m

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *CellIdentifier = @"Cell";
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

        // Configure the cell...

        return cell;
    }

Error:

** Assertion failure in -[UITableView dequeueReusableCellWithIdentifier:forIndexPath:], /SourceCache/UIKit_Sim/UIKit-2372/UITableView.m:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'unable to dequeue a cell with identifier Cell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'

I have changed the code to this it compiles but returns an empty cell.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    // NOTE: Add some code like this to create a new cell if there are none to reuse
    if(cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

    }
    // Configure the cell...
    UILabel *labelMeetingDate = (UILabel *)[cell viewWithTag:11];
    labelMeetingDate.text = @"Meeting Date";

    return cell;
}

Section and rows are set to 1 btw.

How can I add labels and textfields to prototype cell, or why it gives error or returns null?

You need to set the cellIdentifier on the cell itself in the storyboard. Fourth tab over. Listed under the Table View Cell section property Identifier
