Where did my array elements go????

Question

<code>
for (i=0; i<=19; i++){
NSArray *items = [[chunks objectAtIndex:i]componentsSeparatedByString: @"+"];
NSURL *imgurl = [NSURL URLWithString:[items objectAtIndex:0]];
NSData *data = [NSData dataWithContentsOfURL:imgurl];
NSLog(@"adding image: %@",imgurl);
[imgarr addObject:[[UIImage alloc] initWithData:data cache:NO]];
NSLog(@"with data: %@",[imgarr objectAtIndex:1]);
</code>
ok, "items" is an array of an element in the array "chunks" split at "+" the resulting string at index 0 of "items" is a full href to an image. With a for loop i grab the "data" of the afore mentioned href with NSData dataWithContentsOfURL. I then add the "data" as an UIImage object to the imgarr NSMutableArray. I get no errors on the console adding the objects but when i attempt to read them out I get a null.
if i look at the "data" before being added to the array i get... well.... data! (990000 6655222 0584563 552525.......) so i know that i have something to add but it never happens.
any insight would be greatly appreciated.

I think Nonnus misread your poorly formatted code post and thought you were trying to add objects to an NSArray (like items ) rather than an NSMutableArray.
In theory what you're doing should work fine but there are acouple things that are missing and/or odd about your code. I don't see imgarr getting alloc/init-ed but it just might not be shown and I also don't know why you always have the *UIImage imagenamed* reference in your code (but this may be an iPhone element I don't know about).
This should work fine:
NSMutableArray *imgarr = [[[NSMutableArray alloc]init];
NSURL *imgurl = [NSURL URLWithString:[items objectAtIndex: 0]];
NSLog(@"finalURL: %@",imgurl);
NSData *data = [NSData dataWithContentsOfURL:imgurl];
UIImage *img = [[UIImage alloc] initWithData:data cache:YES];
[imgarr addObject:img];
Like I said, unless I'm missing something about the UIImage class on the iPhone this is standard Obj-C/Cocoa stuff.
