為什麼windowController是dealloc但子視圖不是dealloc (why the windowController is dealloc but the subview is not dealloc)


問題描述

為什麼windowController是dealloc但子視圖不是dealloc (why the windowController is dealloc but the subview is not dealloc)

我在 windowController 中添加了一個子視圖 cutView。

當剪切動作完成時,我將 cutView 設置為 nil,並將其委託設置為 nil。我以為cutView會被dealloc。

所以當我再次執行cutAction時,我再次初始化一個curView。

當我關閉窗口時,我發現內存沒有減少。

然後我在cutView和window的dealloc中添加了一條日誌,我發現window的dealloc被調用了,但是cutView從來沒有被調用過。

然後我google了一下,沒有找到解決辦法。

謝謝幫忙~^_^


參考解法

方法 1:

Just like Leo said, there is strong reference to the view so it can not be dealloc. 😁
