NSTableView Table View Cell Memory問題

我有一個非常奇怪的問題，那就是當重新渲染NSTableView時單元格看起來會隨機着色並顯示文本。這是MacOS不是iPhone。NSTableView Table View Cell Memory問題

我使用變量數據中的字典將結果顯示到表中。

最簡單的方法來顯示它看起來應該是這樣的...

當我再次運行模擬，並刪除所有表列並重新創建它們趕上了「年」不是幾個月的，那麼它看起來像這樣。

這是一個非常奇怪的錯誤。我不知道我在做什麼錯誤，可能會造成這種情況，但我懷疑我正在做的事情有內存問題。

這是我的控制器代碼。

事情我已經嘗試：

當我重新模擬，並保持它在幾個月它似乎是可以的，一切正常，這似乎只發生在我切換到多年，這使整體更少的列。

此外，如果我繼續點擊模擬，而在數年後它變得越來越糟。看起來像這最終...

如果我每年開始，並繼續做模擬，它工作正常。切換到每月，它工作正常！這樣做後，切換回年，然後......它再次混亂。

很明顯，當我從年度仿真到每月仿真時，我正在做的事情正在引發一個問題。

我注意到的其他東西是我做測試時錯誤的顏色和文本數據始終處於相同的位置。我在每個點上都在數據字典上做了一個斷點，並且沒有看到任何腐敗現象。

一些有趣的結果調試

所以我加入這一行到這個功能func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {

print("currentColumnIndex=\(currentColumnIndex ?? -1) , row=\(row)")

我碰到下面的調試輸出，當我做這年是很奇怪的，莫名其妙的按順序渲染列然後再按順序？

這個結果有趣的是當每月呈現默認呈現時我這樣做似乎是以不同的順序呈現tableView？

columnType=Monthly 
currentColumnIndex=0 , row=0 
currentColumnIndex=1 , row=0 
currentColumnIndex=2 , row=0 
currentColumnIndex=3 , row=0 
currentColumnIndex=4 , row=0 
currentColumnIndex=5 , row=0 
currentColumnIndex=6 , row=0 
currentColumnIndex=7 , row=0 
currentColumnIndex=8 , row=0 
currentColumnIndex=9 , row=0 
currentColumnIndex=10 , row=0 
currentColumnIndex=11 , row=0 
currentColumnIndex=12 , row=0 
... 

currentColumnIndex=0 , row=0 
currentColumnIndex=1 , row=0 
currentColumnIndex=2 , row=0 
currentColumnIndex=3 , row=0 
currentColumnIndex=4 , row=0 
currentColumnIndex=5 , row=0 
currentColumnIndex=6 , row=0 
currentColumnIndex=7 , row=0 
currentColumnIndex=8 , row=0 
currentColumnIndex=9 , row=0 
currentColumnIndex=10 , row=0 
currentColumnIndex=11 , row=0 
currentColumnIndex=12 , row=0 
... 
currentColumnIndex=0 , row=1 
currentColumnIndex=1 , row=1 
currentColumnIndex=2 , row=1 
currentColumnIndex=3 , row=1 
currentColumnIndex=4 , row=1 
currentColumnIndex=5 , row=1 
currentColumnIndex=6 , row=1 
currentColumnIndex=7 , row=1 
currentColumnIndex=8 , row=1 
currentColumnIndex=9 , row=1 
currentColumnIndex=10 , row=1 
currentColumnIndex=11 , row=1 
currentColumnIndex=12 , row=1 
.... 
currentColumnIndex=0 , row=2 
currentColumnIndex=1 , row=2 
currentColumnIndex=2 , row=2 
currentColumnIndex=3 , row=2 
currentColumnIndex=4 , row=2 
currentColumnIndex=5 , row=2 
currentColumnIndex=6 , row=2 
currentColumnIndex=7 , row=2 
currentColumnIndex=8 , row=2 
currentColumnIndex=9 , row=2 
currentColumnIndex=10 , row=2 
currentColumnIndex=11 , row=2 
currentColumnIndex=12 , row=2

... currentColumnIndex = 120，排= 16

我沒有足夠的字符顯示全模式，但在這裏總結它。

清除表的結果似乎只是暫時幫助，我通過設置data = []並重新加載表來完成。

首先它不是內存問題。

表視圖單元格被重用，你必須確保所有的UI元素都被設置爲一個定義的狀態。

的代碼包含一個if條款，所以你必須添加一個平衡else子句來設置顏色爲默認值，例如：

if let bghighlight = data[row]["highlightrow"] as? [String:NSNumber] { 
     cell.textField?.backgroundColor = NSColor(red: CGFloat(bghighlight["red"]!), green: CGFloat(bghighlight["green"]!), blue: CGFloat(bghighlight["blue"]!), alpha: CGFloat(bghighlight["alpha"]!)) 
     cell.textField?.textColor = NSColor(red: CGFloat(bghighlight["tred"]!), green: CGFloat(bghighlight["tgreen"]!), blue: CGFloat(bghighlight["tblue"]!), alpha: CGFloat(bghighlight["talpha"]!)) 
    } else { 
     cell.textField?.backgroundColor = .white 
     cell.textField?.textColor = .textColor 
    }

我改變了代碼一點使用可選的綁定，這更多高效。 PS：我建議將JSON映射到數據模型，一次又一次創建相同的顏色是不必要的昂貴。

現在試試這一秒 –

我不得不刪除其他標記，但它似乎可以解決顏色問題。其他值爲零的表格單元格由於數據仍然看起來很奇怪，但似乎已經修復了它。我會在這些情況下更新它的樣子。謝謝你。 –

您有任何示例如何將JSON映射到數據模型？我對MacOs桌子的工作方式還是有點新的 –
