UIDatePicker只显示周日的日期吗？

// 获取当前日期
let currentDate = Date()

// 创建一个日历对象
let calendar = Calendar.current

// 获取当前日期的年、月、日、周几等信息
let components = calendar.dateComponents([.year, .month, .day, .weekday], from: currentDate)

// 计算当前日期与周日的日期差
let daysToSunday = (components.weekday! + 7 - 1) % 7

// 获取当前日期的周日
let sunday = calendar.date(byAdding: .day, value: -daysToSunday, to: currentDate)

// 创建一个日期组件对象，用于设置最小和最大日期
var dateComponents = DateComponents()
dateComponents.year = calendar.component(.year, from: sunday!)
dateComponents.month = calendar.component(.month, from: sunday!)
dateComponents.day = calendar.component(.day, from: sunday!)

// 设置UIDatePicker的最小和最大日期
datePicker.minimumDate = calendar.date(from: dateComponents)
datePicker.maximumDate = calendar.date(byAdding: .day, value: 6, to: datePicker.minimumDate!)
