Nothing displayed after splitting a list of image

Question

I have six image URLs in a string named aux. I split it with component separated by newlines. I want to pick images one by one from aux and display each in an ImageView. My code is:

aux = [_homeText.text stringByAppendingString:[NSString stringWithFormat:@" %@  ",item.shortDescription]];
[_homeText setText:aux];  
NSString *list =aux;
NSArray *listItems = [list componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
[listItems count];
if ([listItems objectAtIndex:0]) {
        NSURL *url = [NSURL URLWithString:aux];
            /*UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"hai" message:aux delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];
                [alert show];
                [alert release];*/          
        NSData *data = [NSData dataWithContentsOfURL:url];
        UIImage *image = [[UIImage alloc] initWithData:data]; 
        [_homeImage setImage:image];
}
else if ([listItems objectAtIndex:1])
{
            NSURL *url = [NSURL URLWithString:aux];
            NSData *data = [NSData dataWithContentsOfURL:url];
            UIImage *image = [[UIImage alloc] initWithData:data]; 
            [_homeImage setImage:image];
}

There is no error but I get no image. Why? How do I fix this?

If both data and image not nil, you may try to correctly initialize _homeImage. I don'w know why, but I think what you created _homeImage like this:

_homeImage = [[UIImageView alloc] init];

Try to do something like this:

CGSize imageSize = [image size];
[_homeImage setFrame:CGRectMake([_homeImage frame].origin.x, 
                                [_homeImage frame].origin.y, 
                                imageSize.width, imageSize.height)];
[_homeImage setImage:image];
[image release], image = nil;
