获取农历年月日
用 Calendar (NSCalendar) 获取农历年月日
与公历相似，更改 Calendar (NSCalendar) 的初始化即可，其他代码相同
let calendar: Calendar = Calendar(identifier: .chinese)
NSCalendar *calendar = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierChinese];
结果
用 Calendar 和 DateComponents (NSCalendar 和 NSDateComponents) 获取农历年月日
同上节用 Calendar (NSCalendar) 获取农历年月日
用 DateFormatter (NSDateFormatter) 获取农历年月日
与公历相似，在初始化 DateFormatter (NSDateFormatter) 之后，给 calendar 属性赋值即可，其他代码相同
let formatter: DateFormatter = DateFormatter()
formatter.calendar = Calendar(identifier: .chinese)
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.calendar = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierChinese];
结果
计算日期年份的生肖
自定义一个类 ChineseCalendar 来计算。十二生肖数组写在类外面。
复制代码
private let Zodiacs: [String] = ["鼠", "牛", "虎", "兔", "龙", "蛇", "马", "羊", "猴", "鸡", "狗", "猪"]
十二生肖数组
ChineseCalendar 的类方法
static func zodiac(withYear year: Int) -> String {
let zodiacIndex: Int = (year - 1) % Zodiacs.count
return Zodiacs[zodiacIndex]
}
static func zodiac(withDate date: Date) -> String {
let calendar: Calendar = Calendar(identifier: .chinese)
return zodiac(withYear: calendar.component(.year, from: date))
}
测试
print("Chinese zodiac string:", ChineseCalendar.zodiac(withDate: date))
结果
计算日期年份的天干地支
在 ChineseCalendar 中用类方法计算。天干地支数组写在类外面。
天干地支数组
private let HeavenlyStems: [String] = ["甲", "乙", "丙", "丁", "戊", "己", "庚", "辛", "壬", "癸"]
private let EarthlyBranches: [String] = ["子", "丑", "寅", "卯", "辰", "巳", "午", "未", "申", "酉", "戌", "亥"]
