ios5 - if convert project to Automatic Reference Counting(ARC), Is it still support on iOS 3.X, 4.X?

Question

i not sure about convert project to Automatic Reference Counting(ARC). it still support on iOS 4.X or lower ?

thank you

Answer 1

From what I can gather yes - ARC is done by the compiler and should be thought of as a wizard or helper that checks all of your code and inserts the correct retain and release statements for you.

This will therefore be compatible with older iOS runtimes.

Edit:

IT will support 4.x but not 3.x
