Warning when I fill an array with BOOL

Question

I have this code:

BOOL booleanValue = TRUE;
[arrayZone replaceObjectAtIndex:indexZone withObject:booleanValue];

This code gives me a warning that says:

incompatible integer to pointer conversion: 
sending BOOL to parameter of type 'id'

Why?

Answer 1

You need to box your BOOL with a NSNUmber like this:

BOOL booleanValue = TRUE;
[arrayZone replaceObjectAtIndex:indexZone withObject:[NSNumber numberWithBool:booleanValue]];

Then, to retrieve your BOOL value, you unbox it using boolValue:

BOOL b = [[arrayZone objectAtIndex:index] boolValue];
