Do you have any problem with that? It's system information, how I know apple do not recommend to use it property. By the way I have different behavior, NSLog show RC post = 2. – Gralex Oct 03 '16 at 13:08

The retain count is useless (which is why -retainCount was removed in ARC). CGGetRetainCount doesn't make it any more useful. – bbum Oct 03 '16 at 18:08

The absolute retain count at any given moment is not really useful information. However, in this case I believe it is because ARC is retaining the object before it's passed in to `CFGetRetainCount()`. But perhaps bbum will correct me. – jscs Oct 03 '16 at 18:08
