Multiple views and UITables from one source, how to populate them? - ios

Question

Okay I have three UITableViews that I need to all originate from the same viewcontroller code. I need to populate them all from the .m file of AG_ViewController.
AG_ViewController.h
#import <UIKit/UIKit.h>
#interface AG_ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>{
IBOutlet UITableView *yesterdayTableView;
IBOutlet UITableView *tomorrowTableView;
IBOutlet UITableView *tableView;
IBOutlet UILabel *todaysDate;
IBOutlet UILabel *subtractDate;
IBOutlet UILabel *addDate;
}
#end
AG_ViewController.m
#import "AG_ViewController.h"
#import "AG_Storage.h"
#import "AG_AddItemViewController.h"
#interface AG_ViewController ()
#property NSMutableArray *mainArray;
#property NSMutableArray *yesterdayArray;
#property NSMutableArray *tomorrowArray;
#property NSDate *todayDate;
#property NSDate *tomorrowsDate;
#property NSDate *yesterdaysDate;
#property int counter;
#property(weak,nonatomic)IBOutlet UIButton *yesterdayButton;
#property(weak,nonatomic)IBOutlet UIButton *tomorrowButton;
#property(weak,nonatomic)IBOutlet UIButton *backButton;
#end
#implementation AG_ViewController

self.yesterdayArray = [[NSMutableArray alloc]init];

I've only ever set up one table at a time, so how do I make yesterdayTableView become populated by yesterdayArray for instance?

Answer 1

You can keep one tableView around.
Steps for,One tableView multiple cell as per your need
1) Design seperate cell for yesterday and tomorrow nibs/storyboard
2) swap cell on click of some button tableView:cellForRowAtIndexPath via if else conditions.
or else go for viewController containment

Answer 2

Several ways to do so,
If you only need to display one tableView at a time you could do something like this in your tableView:cellForRowAtIndexPath: data source method:
The stupid way
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (kAppState_Yesterday) { // Set the controllerstate so that it knows that the arrayDatasource should be yesterday
// create and return cell corresponding to yesterdayArray.
}
}
If all your cells look the same, you could have a NSArray *dataSource and just assign it to the different arrays.
The "a bit smarter way"
if userClicksButton `display yesterday array`
self.dataSource = self.yesterdayArray
end
In this way, your tableView:cellForRowAtIndexPath: will be more consistent since if won't be full of conditionals.
If things get more complicated, I would recommend to use Controller Containment.
