Question

I have an NSArray which contains 10 objects from index 0 – 9. Each entry in the array is a quotation.

When my user selects the ‘random quote’ option I want to be able to select a random entry from the array and display the text that is contained in that entry.

Can anyone point me in the right direction on how to achieve this?

Answer 1

I’d recommend you use this instead of hardcoding the 10; that way, if you add more quotations, it will work it out automatically, without you needing to change that number.

NSInteger randomIndex = arc4random()%[array count];
NSString *quote = [array objectAtIndex:randomIndex];
