Question

尝试将此转换为Swift 3.0时遇到问题。

我有：

 public func calendarView(_ view: DDCalendarView, eventsForDay date: Date) -> [Any]? {
        let daysModifier = (date as NSDate).days(from: Date())
        //var daysMod = date.days(from: Date())

        //var newE = self.events(forDay: daysModifier as Int) as NSArray
        var Good = self.events(forDay: daysModifier) as Any
        var dates = [NSMutableArray]()
        var e:DDCalendarEvent

        for e in Good as! [AnyObject] {

            if e.dateBegin(isEqual(date)) as! Bool ==  true || e.dateEnd(isEqual(date)) as! Bool ==  true {
                dates.append(e as! NSMutableArray)
            }
   }

       return dates
    }

如果e.dateBegin（isEqual（Date））{}给出此错误的条件。而在Objective-C代码中则是：

- (NSArray *)calendarView:(DDCalendarView *)view eventsForDay:(NSDate *)date {
    //should come from db ;) NOW using testdata
    NSInteger daysMod = [date daysFromDate:[NSDate date]];
    NSArray *newE = [self eventsForDay:daysMod]; //always today ;)

    NSMutableArray *dates = [NSMutableArray array];
    for (DDCalendarEvent *e in newE) {
        if([e.dateBegin isEqualDay:date] ||
           [e.dateEnd isEqualDay:date]) {
            [dates addObject:e];
        }
    }
    return dates;
}

及其为isEqualDay函数返回的Bool值

- (BOOL)isEqualDay:(NSDate *)date {
    NSDateComponents *compA = self.currentCalendarDateComponents;
    NSDateComponents *compB = date.currentCalendarDateComponents;
    return ([compA day]==[compB day] && [compA month]==[compB month ]&& [compA year]==[compB year]);
}

任何解决方案？

这一行：

if e.dateBegin(isEqual(date)) as! Bool ==  true || e.dateEnd(isEqual(date)) as! Bool ==  true {

应该是：

if e.dateBegin.isEqualDay(date) == true || e.dateEnd.isEqualDay(date) == true {

这假设您已将isEqualDay:方法翻译为Date上的扩展功能。

BTW - 你的翻译还有很多其他问题。以上仅涵盖了您在问题中询问的一条特定行。

以下内容应该是您想要的：

public func calendarView(_ view: DDCalendarView, eventsForDay date: Date) -> [Date] {
    let daysModifier = date.days(from: Date()) // return Int
    let newE = self.events(forDay: daysModifier) // return [DDCalendarEvent]

    var dates = [Date]()
    for e in newE {
        if e.dateBegin.isEqualDay(date) == true || e.dateEnd.isEqualDay(date) == true {
            dates.append(e)
        }
    }

    return dates
}

无法调用非函数类型的值
