如何调整两个标签之间的UIDatePicker大小

// 创建两个标签和一个UIDatePicker对象
let label1 = UILabel(frame: CGRect(x: 0, y: 100, width: 200, height: 30))
let datePicker = UIDatePicker(frame: CGRect(x: 0, y: 150, width: 200, height: 200))
let label2 = UILabel(frame: CGRect(x: 0, y: 350, width: 200, height: 30))

// 计算两个标签之间的垂直距离
let verticalSpacing = label2.frame.origin.y - (label1.frame.origin.y + label1.frame.size.height)

// 计算新的UIDatePicker高度
let newDatePickerHeight = verticalSpacing - 20 // 减去一些额外的空间

// 创建新的CGRect对象，并将其分配给UIDatePicker的frame属性
datePicker.frame = CGRect(x: 0, y: label1.frame.origin.y + label1.frame.size.height + 10, width: 200, height: newDatePickerHeight)

// 将标签和UIDatePicker添加到视图中
view.addSubview(label1)
view.addSubview(datePicker)
view.addSubview(label2)
