ios - 使用 Swift 3.0 在 iOS 中禁用以前的日期、月份、年份 JTAppleCalendar

Question

我正在使用这个库：
https ://github.com/orazz/CalendarPopUp

假设我有一个用户注册日期，它是 28/9/2017。现在我只想启用下一个日期、月份和年份之间的日期。应禁用以前的日期、月份和年份。

我怎样才能做到这一点？

如何禁用滚动和选择上一个日期和月份？

Answer 1

使用它来设置最小和最大日期。您可以更改任何组件，例如日、月、年。

目标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];

迅速

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
