NSMutableArray insertObject:atIndex: problems
I have a problem with this method. I have eleven images with this names: Articulo 1.png, Articulo 2.png, etc. I dont know why , but my array of images only has the last image. Am I doing something wrong?
Here is my example:
NSMutableArray imagenesA = [[NSMutableArray alloc]init];
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
UIImage *image = [[UIImage alloc]init];
UIImageView *imageView = [[UIImageView alloc]init];
NSMutableString *name = [[NSMutableString alloc]init];
NSMutableString *name2 = [[NSMutableString alloc]init];
for (int y = 0; y < 11; y++) {
name = [NSMutableString stringWithFormat:@"Articulo %d.png",y+1];
image = [UIImage imageNamed:name];
imageView = [[UIImageView alloc] initWithImage:image];
name2 = [NSMutableString stringWithFormat:@"Articulo %d",y+1];
[dict setObject:name2 forKey:@"nombre"];
[dict setObject:imageView forKey:@"imagen"];
[imagenesA insertObject:dict atIndex:y];
// show all dictionarys
NSLog(@"DICT: %@", dict);
}
// show index 0 element --> must be Articulo 1 but...
NSDictionary *d = [[NSDictionary alloc]
initWithDictionary:[imagenesA objectAtIndex:0]];
NSLog(@"*********************%@***********************",d);
Console response:

Yes. @albertamg is correct in his comment above. Your for
loop should look like the following.
for (int y = 0; y < 11; y++) {
// Other codes here
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:name2 forKey:@"nombre"];
[dict setObject:imageView forKey:@"imagen"];
[imagenesA insertObject:dict atIndex:y];
}
