我使用核心数据来存储对象,我的project.There是对象中的一个日期字段,.I想要检查iphone的Tapku日历组件的点击日期。我的对象上的日期格式为
2011-01-10,这是一个本地化日期。
如何将日期与tapku日历控件返回的日期进行核对。

是的,你可以,这是我做了什么让它工作:
在方法上:(NSArray*)calendarMonthView:(TKCalendarMonthView *)monthView marksFromDate:(NSDate *)startDate toDate:(NSDate *)lastDate
警告:确保将您的NSDate对象强制转换为no time和GMT:0日期,以便使日期比较起作用(通过艰苦的方式学会了这一点...)
下面是一些代码。
self.marksArray = [NSMutableArray array];
self.dataDictionary = [NSMutableDictionary dictionary];
NSCalendar *cal = [NSCalendar currentCalendar];
[cal setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSDateComponents *comp = [cal components:(NSMonthCalendarUnit | NSMinuteCalendarUnit | NSYearCalendarUnit | NSDayCalendarUnit | NSWeekdayCalendarUnit | NSHourCalendarUnit | NSSecondCalendarUnit) fromDate:start];
NSDate *ds = [cal dateFromComponents:comp];
// Init offset components to increment days in the loop by one each time
NSDateComponents *offsetComponents = [[NSDateComponents alloc] init];
[offsetComponents setDay:1];
while (YES) {
// Is the date beyond the last date? If so, exit the loop.
// NSOrderedDescending = the left value is greater than the right
if ([ds compare:end] == NSOrderedDescending) {
break;
}
NSIndexSet *indexes = [arrayWithObjectsFromCoreData indexesOfObjectsPassingTest:
^BOOL (id el, NSUInteger i, BOOL *stop) {
NSDate *upd = [(YOUR_ENTINY *)el updated];
NSDate *day=[self midnightUTC:upd];
if([ds isSameDay:day]){
return TRUE;
}
return FALSE;
}];
if (indexes.count>0) {
[self.marksArray addObject:[NSNumber numberWithBool:YES]];
[self.dataDictionary setObject:[wods objectsAtIndexes:indexes] forKey:ds];
}else {
//no wods in this date
[self.dataArray addObject:[NSNumber numberWithBool:NO]];
}
// Increment day using offset components (ie, 1 day in this instance)
ds = [cal dateByAddingComponents:offsetComponents toDate:ds options:0];
}
[offsetComponents release];可以在以下位置找到midnightUTC方法:http://www.voidasterisk.org/post/4209842795/how-to-calculate-nsdate-of-midnight-in-ios

我需要更多的信息,但是tapku库在NSDate上有一个名为isSameDay的扩展方法,所以您可以使用它:
if ([myDate isSameDay:returnedDate])
// Do something here这就是你要找的吗?
