使用同一TableViewCell原型的多个自定义UITableViewCell

Question

I like to see what are my options to do this in iOS7. I have a TableViewCell prototype with identifier TableViewCell_RightDetailID in an UITableViewController . I also have two other custom tableviewcell classes that would like to use this prototype.

Any ideas on how to do this? Not sure if its possible?

@interface TableViewCellA : UITableViewCell
@interface TableViewCellB : UITableViewCell

Answer 1

I think something like this should work:

TableViewController.m

#import "TVC.h"
#import "TableViewCellA.h"
#import "TableViewCellB.h"

@implementation TVC

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

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

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if(indexPath.row == 0)
    {
        TableViewCellA *cell = [tableView dequeueReusableCellWithIdentifier:@"TableViewCell_RightDetailID"];
        // title, detaillabel etc
        return cell;

    }
    else
    {
        TableViewCellB *cell = [tableView dequeueReusableCellWithIdentifier:@"TableViewCell_RightDetailID"];
        // TO DO
        return cell;
    }
}

@end

Answer 2

Since the class of the cell is set in the prototype in the storyboard, it's not possible to change it short of copying the prototype in the storyboard (and using distinct reuse identifiers)

This actually might be an argument for doing the layout in code and registering all three classes via [UITableView registerClass:forCellReuseIdentifier:]
