ios: String to Date conversion - iphone

Question

I am trying to convert my date from NSString to NSDate using following code
NSDateFormatter *dateformatter = [[NSDateFormatter alloc]init];
[dateformatter setDateStyle:NSDateFormatterShortStyle];
[dateformatter setTimeStyle:NSDateFormatterNoStyle];
[dateformatter setDateFormat:#"dd/MM/yyyy"];
NSDate *myDate = [[NSDate alloc] init];
currMonth = 3;
currYear = 2012;
NSString *str = [NSString stringWithFormat:#"01/%2d/%d", currMonth, currYear];
str = [str stringByReplacingOccurrencesOfString:#" " withString:#"0"];
myDate = [dateformatter dateFromString:str];
NSLog(#"myStr: %#",str);
NSLog(#"myMonth: %2d",currMonth);
NSLog(#"myYear: %d",currYear);
NSLog(#"myDate: %#",myDate);
Above code is giving me wrong date. Can anyone please help?

Answer 1

What is your output? Keep in mind, that NSDate is in UTC.
2012-03-01 00:00:00 (GMT+1) is 2012-02-39 23:00:00 (UTC)
Another tip:
%02 formats your integers with leading zeros.

Answer 2

Try this:
-(NSDate *)dateFromString:(NSString *)string
{
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:#"en_US"];
[dateFormat setLocale:locale];
[dateFormat setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSTimeInterval interval = 5 * 60 * 60;
NSDate *date1 = [dateFormat dateFromString:string];
date1 = [date1 dateByAddingTimeInterval:interval];
if(!date1) date1= [NSDate date];
[dateFormat release];
[locale release];
return date1;
}

try
NSDateFormatter *dateformatter = [[NSDateFormatter alloc]init];
[dateformatter setDateStyle:NSDateFormatterShortStyle];
[dateformatter setTimeStyle:NSDateFormatterNoStyle];
[dateformatter setDateFormat:#"dd/MM/yyyy"];
NSDate *myDate = [[NSDate alloc] init];
int currMonth = 3;
int currYear = 2012;
NSString *str = [NSString stringWithFormat:#"01/%2d/%d", currMonth, currYear];
str = [str stringByReplacingOccurrencesOfString:#" " withString:#"0"];
//SET YOUT TIMEZONE HERE
dateformatter.timeZone = [NSTimeZone timeZoneWithAbbreviation:#"PDT"];
myDate = [dateformatter dateFromString:str];
NSLog(#"myStr: %#",str);
NSLog(#"myMonth: %2d",currMonth);
NSLog(#"myYear: %d",currYear);
NSLog(#"myDate: %#",myDate);
