Adding integer values as contents of an array,iphone

arrays, integer, iphone

Solution

`NSArray`-s cannot store non-`id` objects. You have to box it into an `NSNumber`:

NSUInteger i;
for (i=0;i<5;i++) {
   [array addObject:[NSNumber numberWithUnsignedInteger:i]];
}

or use a `CFArray` with custom callbacks (but you sacrifice readability for performance), or use `std::vector<NSUInteger>` (but you need to use Objective-C++).

Problem

I need to store some integer values as the contents of an array. But when i try to do so, it throws a warning, passing argument 1 of 'addObject' makes pointer from integer without a cast. And obviously the value is not stored in the array. Here's thecode. ``` NSUInteger i; for (i=0;i<5;i++){ [array addObject:i];} ```
