NSTableView Table View Cell Memory问题

我有一个非常奇怪的问题，那就是当重新渲染NSTableView时单元格看起来会随机着色并显示文本。这是MacOS不是iPhone。NSTableView Table View Cell Memory问题

我使用变量数据中的字典将结果显示到表中。

最简单的方法来显示它看起来应该是这样的...

当我再次运行模拟，并删除所有表列并重新创建它们赶上了“年”不是几个月的，那么它看起来像这样。

这是一个非常奇怪的错误。我不知道我在做什么错误，可能会造成这种情况，但我怀疑我正在做的事情有内存问题。

这是我的控制器代码。

事情我已经尝试：

当我重新模拟，并保持它在几个月它似乎是可以的，一切正常，这似乎只发生在我切换到多年，这使整体更少的列。

此外，如果我继续点击模拟，而在数年后它变得越来越糟。看起来像这最终...

如果我每年开始，并继续做模拟，它工作正常。切换到每月，它工作正常！这样做后，切换回年，然后......它再次混乱。

很明显，当我从年度仿真到每月仿真时，我正在做的事情正在引发一个问题。

我注意到的其他东西是我做测试时错误的颜色和文本数据始终处于相同的位置。我在每个点上都在数据字典上做了一个断点，并且没有看到任何腐败现象。

一些有趣的结果调试

所以我加入这一行到这个功能func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {

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

我碰到下面的调试输出，当我做这年是很奇怪的，莫名其妙的按顺序渲染列然后再按顺序？

这个结果有趣的是当每月呈现默认呈现时我这样做似乎是以不同的顺序呈现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

我没有足够的字符显示全模式，但在这里总结它。

清除表的结果似乎只是暂时帮助，我通过设置data = []并重新加载表来完成。

首先它不是内存问题。

表视图单元格被重用，你必须确保所有的UI元素都被设置为一个定义的状态。

的代码包含一个if条款，所以你必须添加一个平衡else子句来设置颜色为默认值，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 
    }

我改变了代码一点使用可选的绑定，这更多高效。 PS：我建议将JSON映射到数据模型，一次又一次创建相同的颜色是不必要的昂贵。

现在试试这一秒 –

我不得不删除其他标记，但它似乎可以解决颜色问题。其他值为零的表格单元格由于数据仍然看起来很奇怪，但似乎已经修复了它。我会在这些情况下更新它的样子。谢谢你。 –

您有任何示例如何将JSON映射到数据模型？我对MacOs桌子的工作方式还是有点新的 –
