[bodalal]

hi all

 

My app contain Calendar date picker and label

 

when i chose date from Calendar picker as "Birth date"

 

then to calculate the age , it should calculate date between today (now) and the date in calendar picker

 

i did everything right in interface builder, then i wrote this code :

 

#import "AgeCalc.h"

@implementation AgeCalc

- (IBAction)calcut:(id)sender {

NSDate *dBirth = [NSDate date];
NSDate *today = [NSDate date];

NSCalendar *gregorian = [[NSCalendar alloc]
						 initWithCalendarIdentifier:NSGregorianCalendar];

unsigned int unitFlags = NSMonthCalendarUnit | NSDayCalendarUnit;

NSDateComponents *components = [gregorian components:unitFlags fromDate:dBirth toDate:today options:0];
int years = [components year];
int months = [components month];
int days = [components day];

[txtResult setIntValue:years & @" Years " & months & @" Months" & days & @"Days"];

}
@end

 

 

 

 

BUT it does not work, nothing show up in the label

Because it should be something like this (i mean should cuz i can't see the whole project):

 

[txtResult setStringValue: [NSString stringWithFormat: @"Years: %i Months: %i Days: %i", years, months , days]];

 

Hope it helped....
