标题Re: [问题] 关於retain
时间Thu Jan 16 20:14:58 2014
There should be no reason to explicitly ask an object what its retain count
is (see retainCount). The result is often misleading, as you may be unaware
of what framework objects have retained an object in which you are
interested. In debugging memory management issues, you should be concerned
only with ensuring that your code adheres to the ownership rules.

※ 引述《santaclub (圣诞青年)》之铭言：
: 各位好
: 最近又遇到一个困难...
: 一个该死的property一直没有被删除 纵使看起来应该是没有retain count了
: 现在只知道 (CFGetRetainCount((__bridge CFTypeRef) something)
: 可以读到something 的retain count,
: 请问有没有办法可以看他的retain count到底是谁给的?
: 有请高人指点 ....感恩
