How to get number of days between two dates objective-c
13,733
By default [NSDate date]
return date in like 2013-08-06 08:50:25 +0000
and you have set your formatter to yyyy-MM-dd
this, so you have to convert your startDate to yyyy-MM-dd
this form..
Try this
NSDateFormatter *f = [[NSDateFormatter alloc] init];
[f setDateFormat:@"yyyy-MM-ddHH:mm:ss ZZZ"];
NSDate *startDate = [NSDate date];
NSLog(@"%@",startDate);
NSDate *endDate = [f dateFromString:end];
NSLog(@"%@",endDate);
NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [gregorianCalendar components:NSDayCalendarUnit
fromDate:startDate
toDate:endDate
options:0];
return components.day;

I'm trying to make a label that says how many days left till event. I want to calculate the difference between todays date and the events date. I'm using this code and its giving me -4600. It works fine till I use todays date.
NSDateFormatter *f = [[NSDateFormatter alloc] init]; [f setDateFormat:@"yyyy-MM-dd"]; NSDate *startDate = [NSDate date]; NSDate *endDate = [f dateFromString:end]; NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *components = [gregorianCalendar components:NSDayCalendarUnit fromDate:startDate toDate:endDate options:0]; return components.day; return components.day;
