您已經設置ibloutlet，然後從類中刪除，但通過廈門國際銀行文件不解除綁定 –

確保你沒有在您的視圖控制器中的另一個鏈接對pickerView不存在的IBOutlet中。 – Vlad

@William您先前已經採取了「pickerView」因爲這似乎是改變「選擇器」。所以，你需要解除綁定和綁定「裝載機」正確IBOutlet中一個IBOutlet中。 –

爲拾取您的引用插座設置「pickerView」而不是「選擇器」。

轉到故事板並選擇視圖控制器上的選取器視圖。
選擇「顯示所有連接檢查」在公用事業部分（Xcode中的右選項卡）。
刪除引用連接到「pickerView」插座。
添加引用出口「選擇器」。

除'picker'（UIPickerView的IBOutlet）外，在連接檢查器中還有一個出口連接。

打開您的連接檢查器並刪除與'pickerView'實例的連接。

Steps: Select Storyboard >> Select View Controller >> Open Connection Inspector >> Check all IBOutlet connections and find 'pickerView' >> Remove connection of 'pickerView'
