Swift 2：IBOutlet Collection [UIButton]！泄漏记忆 [英] Swift 2 :IBOutlet Collection [UIButton]! leaks memory

问题描述

最近在我的应用程序中，我发现我的UIButton插座系列正在泄漏内存。

Recently in my app I have found out that my UIButton outlet collection is leaking memory.

我所拥有的只是

    @IBOutlet var TabBarButtons: [UIButton]!

来自Instrument

And from Instrument

谁能告诉我出了什么问题？随着时间的推移，NSArray中的变量数量不断增长，我所拥有的是一个包含4个UIButton的数组。

Can anyone tell me what's gone wrong? As time goes on, the amount of variables in the NSArray keeps growing and all I have is an array with 4 UIButtons from IB.

推荐答案

这是一个错误。参考 rdar：// 24272775

解决方法现在是取代[UIButton]！与NSArray！并在以后使用时将其内容转换为UIButton。

Workaround for now is to replace [UIButton]! with NSArray! and cast its contents to UIButton later when used.
