    @ccp0101 难道你之前一直用垃圾回收?

    关掉,尽量不想用这东西,还没搞懂现在。
    感觉用了之后可能比没用这东西引发的问题更多,特别先阶段还不完善。

    @lldong WWDC 2011里有几个讲到ARC的sessions,最吸引我的是它比手动retain/release/autorelease快几倍

    arc在编译的时候会自动帮你retain和release,
    而且生成的代码速度比手写快6倍,为什么不用呢?

    果断的启用,既然已经默认启用了,说明手动release早晚会非主流,没必要坚持手动管理内存

    我觉得还是开启吧,毕竟是apple推的!
