Parallel Arrays - iphone

Question

I am creating an iPhone game which will call a generic Newsfeed and apply with a random share, affecting the share price with a low medium or high increase/decrease. It was suggested I use parallel arrays to go about this. Is that the best method? And has anyone got a useful link for tutorials in how to do so?
I have a simple array setup. But I am new to x-code and I need to get something coded to call items from the array.
#import "NewsFeedViewController.h"
#interface NewsFeedViewController ()
#end
#implementation NewsFeedViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
//Setup NSArray
items = [[NSArray alloc] initWithObjects:#"Galaxy", #"Redbull", #"Boost", nil];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
return items.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:#"cell"];
}
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
cell.textLabel.text = [items objectAtIndex:indexPath.row];
return cell;
}
#end

Answer 1

If you are looking for Parallel array, then this is an example :
NSArray *alphabets=#[#"A",#"B",#"C",#"D"];
NSArray *words=#[#"Apple",#"BlackBerry",#"Cognizant",#"Dell"];
for (NSInteger i=0; i<alphabets.count; i++) {
NSLog(#"%# for %#",alphabets[i],words[i]);
}
It will be clear that, two arrays are related by 1-1 mapping, and while looping, I used same index to match the record.

Answer 2

I just answered an unrelated question, but the project i built uses three arrays as datasources for a TableView.
Sample Project link is below, but this is the meat of the code:
https://dl.dropbox.com/u/3660978/UniversalTableView.zip
-(void)populateArrays {
// New literal syntax of interacting with Arrays.
namesArray = #[#"Homer Simpson",#"Marge Simpson",#"Bart Simpson",#"Lisa Simpson",#"Maggie Simpson",#"Mr. Burns",
#"Principal Skinner",#"Krusty the Clown"];
descriptionsArray = #[#"Homer is a lazy, but also a funny father",
#"Marge is smart, but not smart enough to not marry Homer lol",
#"Bart is just a smart-alec, but he is really funny too",
#"Lisa is the smartest one and the brunt of most jokes",
#"Maggie is just the baby of the family",
#"Mr. Burns is Homer's boss and evil too",
#"Principal Skinner is Bart and Lisa's principal at school",
#"Krusty is always clowning around (not really that funny though)"];
imagesArray = #[#"homer.jpg",#"marge.jpg",#"bart.jpg",#"lisa.jpg",#"maggie.jpg",#"burns.jpg",
#"skinner.jpg",#"krusty.jpg"];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [namesArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"MyCustomCell";
CustomTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell...
cell.customLabel.text = [namesArray objectAtIndex:indexPath.row];
cell.customTextView.text = [descriptionsArray objectAtIndex:indexPath.row];
cell.customImageView.image = [UIImage imageNamed:[imagesArray objectAtIndex:indexPath.row]];
return cell;
}
