禁用以前的日期，月份，年份JTAppleCalendar iOS中使用雨燕3.0

Question

我使用這個庫：
https://github.com/orazz/CalendarPopUp

比方說，我有一個用戶註冊的日期，它是28/9/2017。現在我只想在下一個日期，月份和年份之間啓用日期。 應禁用以前的日期，月份和年份。

我該怎麼做？

如何禁用滾動和選擇上一個日期和月份？

Answer 1

使用此設置最小和最大日期。您可以更改任何組件，如日，月，年。

目標C

NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 
NSDate *currentDate = [NSDate date]; 
NSDateComponents *comps = [[NSDateComponents alloc] init]; 
[comps setMonth:3]; 
NSDate *maxDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0]; 
[comps setMonth:-3]; 
NSDate *minDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0]; 
[datePicker setMaximumDate:maxDate]; 
[datePicker setMinimumDate:minDate];

let gregorian: NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)! 
let currentDate: NSDate = NSDate() 
let components: NSDateComponents = NSDateComponents() 

components.month = -3 
let minDate: NSDate = gregorian.dateByAddingComponents(components, toDate: currentDate, options: NSCalendarOptions(rawValue: 0))! 

components.month = 3 
let maxDate: NSDate = gregorian.dateByAddingComponents(components, toDate: currentDate, options: NSCalendarOptions(rawValue: 0))! 

self.datePicker.minimumDate = minDate 
self.datePicker.maximumDate = maxDate
