create array with while-loop in cocoa

Question

I have created a while-loop in which temporary strings are created (string is updated everytime that loop performs). How can I create an array out of these temporary strings?

Answer 1

It sounds like you're looking for something like this:

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

while(foo) {
    // create your string
    [array addObject:string];
}

Answer 2

-(NSArray*) makeArray
{
    NSMutableArray* outArr = [NSMutableArray arrayWithCapacity:512]; // outArr is autoreleased
    while(notFinished)
    {
      NSString* tempStr = [self makeTempString];
      [outArr addObject:tempStr]; // will incr retain count on tempStr
    }
    return [outArr copy]; // return a non-mutable copy
}
