您已经设置ibloutlet，然后从类中删除，但通过厦门国际银行文件不解除绑定 –

确保你没有在您的视图控制器中的另一个链接对pickerView不存在的IBOutlet中。 – Vlad

@William您先前已经采取了“pickerView”因为这似乎是改变“选择器”。所以，你需要解除绑定和绑定“装载机”正确IBOutlet中一个IBOutlet中。 –

为拾取您的引用插座设置 “pickerView” 而不是 “选择器”。

转到故事板并选择视图控制器上的选取器视图。
选择“显示所有连接检查”在公用事业部分（Xcode中的右选项卡）。
删除引用连接到 “pickerView” 插座。
添加引用出口“选择器”。

除'picker'（UIPickerView的IBOutlet）外，在连接检查器中还有一个出口连接。

打开您的连接检查器并删除与'pickerView'实例的连接。

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