解决方法

不是 llvm document on ARC

Automatic Reference Counting implements automatic memory management for Objective-C objects and blocks,freeing the programmer from the need explicitly insert retains and releases. It does not provide a cycle collector; users must explicitly manage lifetime instead.

A retainable object pointer (or retainable pointer) is a value of a retainable object pointer type (retainable type). There are three kinds of retainable object pointer types:

block pointers (formed by applying the caret (^) declarator sigil to a function type)

Objective-C object pointers (id,Class,NSFoo*,etc.)

typedefs marked with __attribute__((NSObject))

Other pointer types,such as int* and CFStringRef,are not subject to ARC’s semantics and restrictions.
