iOS UIPickerView 自定义行 View 宽度错误

Question

为以下方法返回自定义 View 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()
}

并返回全宽:

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

不调整行 View 的大小:O

Answer 1

通过将自定义 View 的初始框架设置为 .zero 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
}
