我在解除分配IGListKit部分时遇到问题。尝试使用 Xcode 内存图调试问题。
我的设置是AuthController -> AuthViewModel -> AuthSocialSectionController -> AuthSocialViewModel和其他一些部分。
如果用户未登录，则AuthController会从应用程序的多个部分呈现。当我点击关闭时， AuthViewModel和 AuthController 会被释放，但它的底层部分不会。在这种情况下，内存图没有显示任何泄漏，但deinit没有调用方法。
但是，当我尝试使用社交帐户进行授权（成功）然后查看内存图时，它会显示这些部分并没有像这样被释放：
在这种情况下，AuthViewModel 也不会被释放，但一段时间后它会释放，但它可能发生也可能不发生。
我检查了每个闭包和委托的弱参考，但仍然没有运气。
我的代码，我认为最有意义：

vm.delegate = delegate
return vm
