几天前,我下载了Xcode 4.2.1。
但奇怪的是,当我试图在个案变数中使用释放方法时,
错误信息如下所示。
错误信息的原因是什么?
我如何解决错误信息?
你设立了一个自动参比项目。 它为你们保留和释放,而你不允许我这样做。 这是货物。
Transitioning to ARC Release Notes
Automatic Reference Counting
这是因为Xcode 4.2.1正在使用OS 5 SDK,它实施了一个称为ARC的新概念。 这样做的目的是防止开发商担心何时和在何处释放物体,从而方便人们的生活。 相反,如果不再需要,它就以最优化的方式向你们释放。 因此,取消了“释放”方法。
