I want to get firstdate、lastdate of month，I try
NSDateComponents *components = [calendar components:units fromDate:[NSDate date]];
[components setDay:1];
self.currentDate = [calendar dateFromComponents:components];
int m = components.month;
int y = components.year;
int d = components.day;
log: 2012,5,1
How can i get lastdate od month?
please give me some advice，thank you!!
Ok, since I'm rolling my own calendar control, I went ahead and created a NSCalendar category. Here's my lastOfMonth method:
- (NSDate *)lastOfMonth:(NSDate *)date
{
NSDateComponents *dc = [self components:NSEraCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit fromDate:date];
NSRange dim = [self rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:date];
dc.day = dim.length;
return [self dateFromComponents:dc];
}
You can get last date of month using :-
NSDate currDate=[NSDate date];
-(NSString *)getLastDateMonth:(NSDate *)currDate{
NSCalendar *gregCalendar=[[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease];
NSDateComponents *components=[gregCalendar components:NSMonthCalendarUnit|NSYearCalendarUnit fromDate:currDate];
NSInteger month=[components month];
NSInteger year=[components year];
if (month==12) {
[components setYear:year+1];
[components setMonth:1];
} else {
[components setMonth:month+1];
}
[components setDay:1];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateStyle:NSDateFormatterShortStyle];
NSString *lastDateOfMonth = [dateFormat stringFromDate:(NSDate *)[[gregCalendar dateFromComponents:components] dateByAddingTimeInterval:-86400]];
dateFormat=nil;
return lastDateOfMonth;
}
