They both do the same thing, return the value of an object's property called property. So, what is the difference other than syntax? Same thing also happens with arrays, 

[[numberArray objectAtIndex:indexInt] integerValue]

is the same as 

((NSNumber*)numberArray[indexInt]).integerValue

At least it has been the same so far.

There is absolutely no difference between using the dot notation or the square bracket messaging syntax. - with the caveat that you can send any message to id, but you can't get or set any property of id through dot syntax

    That's almost true, with the caveat that you can send any message to `id`, but you can't get or set any property of `id` through dot syntax (As the OP's example shows, you have to cast explicitly to use dot syntax.) – ahruss Aug 08 '14 at 21:02
