Objective C Boolean Array

Question

I need to utilize an array of booleans in objective-c. I\'ve got it mostly set up, but the compiler throws a warning at the following statement:

[updated_use         


        

Answer 1

Yep, that's exactly what it is: the NS* containers can only store objective-C objects, not primitive types.

You should be able to accomplish what you want by wrapping it up in an NSNumber:

[updated_users replaceObjectAtIndex:index withObject:[NSNumber numberWithBool:YES]]

or by using @(YES) which wraps a BOOL in an NSNumber

[updated_users replaceObjectAtIndex:index withObject:@(YES)]]

You can then pull out the boolValue:

BOOL mine = [[updated_users objectAtIndex:index] boolValue];
