Question

I’m trying to access an array using another array integer value as an index.

 NSInteger index=[appDelegate.randomRiddles objectAtIndex:appDelegate.randomRiddlesCounter];
 int i = index;
 questionText.text = [[appDelegate.currentRiddlesContent objectAtIndex:i] objectForKey:@"question"];

//where appDelegate.randomRiddlesCounter is an NSInteger and appDelegate.randomRiddles is a NSMutableArray

However I’m getting incompatible pointer to int conversion warning. How can I fix this above code? The warning I get is coming from the first line.

Answer 1

Try:

NSNumber *index = [appDelegate.randomRiddles objectAtIndex: appDelegate.randomRiddlesCounter];
int i = [index intValue];
questionText.text = [[appDelegate.currentRiddlesContent objectAtIndex: i] objectForKey: @"question"];

NSInteger is an integral type, not an object.
