Example NSMutableArray

Hagan un Navigation-based Aplication y llamenlo NSArray.

En RootViewController.h pongan esto:

Código:

@interface RootViewController : UITableViewController {
 NSMutableArray *Lista;
}

@end

Eso no necesita explicacion.

Luego en el archivo .m en viewDidLoad pongan esto:

Código:

- (void)viewDidLoad {
    [super viewDidLoad];
self.navigationItem.title = @"Chistes";
 Lista = [[NSMutableArray alloc] init];
 [Lista addObject:@"Chistes general"];
 [Lista addObject:@"Ayer pase por tu casa"];
}

La 3ra linea le pone un titulo. Yo le puse chistes. Pueden ponerle como quieran. La que sige pone el Array en la vista principal. Las ultimas dos lineas le ponen objetos.

Luego busquen esto, y lo cambian a esto:

Código:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return[Lista count];
}

Aqui le ponemos que la cantidad de lineas se deben a la cantidad de objetos

Luego pongan esto:

Código:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    
 // Configure the cell.
 NSString *cellValue =[Lista objectAtIndex:indexPath.row];
 cell.textLabel.text = cellValue ;
    return cell;
}

//
// RootViewController.m
// NSAray
//

#import "RootViewController.h"


@implementation RootViewController


- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = @"Tips de Photoshop";
Lista = [[NSMutableArray alloc] init];
[Lista addObject:@"Tip 1"];
[Lista addObject:@"Tip 2"];
[Lista addObject:@"Tip 3"];
[Lista addObject:@"Tip 4"];
[Lista addObject:@"Tip 5"];
