目标C：ARC错误（自动释放问题） [英] Objective C: ARC errors (Automatic release problems)

问题描述

可能重复：

Xcode 4 Final - armv6 armv7问题，同时链接armv6库

在我运行iOS 4.3.3的实际手机上配置之前，一切正常。
我打开了自动参考，所以我不必担心发布任何东西，但也许我做错了，不发布的概念对我来说是新的。我收到这些错误：

Everything was working fine until I provisioned on my actual phone running iOS 4.3.3. I have automatic referencing turned on so I don't have to worry about releasing anything, but maybe I'm doing something wrong, the concept of not releasing is new to me. I get these great error:
