Question

I seem to be having a problem with the NSMutableArray.

Here’s my code:

NSMutableArray *returnArray = [[NSMutableArray alloc] init];

while(condition) {
    NSInteger temp = someNumber;
    [returnArray addObject: temp];

}

But as soon as it hits the addObject message, the program seg faults. Any advice?

Answer 1

You can’t add primitives like integers to an array, only objects (hence the name addObject:). If you want to add numbers, you have to convert them to an NSNumber, or one of the related classes.
