2. 如何卸载国际交易日志的意见
原标题:How to unload view of UIViewController

我有像刺.一样的习俗控制,显示其中很多控制人员也与其他控制人员有我的禁忌,因此,我的记忆中有许多,因为每个控制者都保存在记忆中。 因此,我想卸下看不见的控制器,但我没有发现任何方法卸载国际笔记。 我如何能够这样做?

PS。 我不能使用UITab BarController,实际上可以 t。

最佳回答

You don t. UIViewControllers don t get unloaded in low memory, just their views do.

这在<条码>didReceiveMemory Warning上,在您本人看来是控制器,在出现低记忆警告时自动被点燃。

取消这一规定,并卸载可在<代码>viewDid Load中重造的任何东西。

问题回答

删除观点控制者的观点,从表面上删除,释放控制者。 工作完成。

我知道它是一种老的read,但可能对人有用。

You can unload viewControllers view by calling:

[viewControllerWhoseViewYouWantToUnload didReceiveMemoryWarning];
