iOS UIPickerView自定义行视图宽度错误

返回以下方法的自定义视图以自定义选择器行：

public override func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
    return PickerAccessoryView.instantiateFromNib()
}

回到全宽：

public func pickerView(_ pickerView: UIPickerView, widthForComponent component: Int) -> CGFloat {
    return pickerView.frame.width
}

不调整行视图的大小：O

通过将自定义视图的初始帧设置为0来解决：

public override func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
    let view = PickerAccessoryView.instantiateFromNib()
    view.frame = .zero
    return view
}

通过将自定义视图的初始帧设置为.0来解决此问题：

public override func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
    let view = PickerAccessoryView.instantiateFromNib()
    view.frame = .zero
    return view
}
