Set Minimum date to UIDatePicker

I have a date in开发者_Python百科 UILabel(like 'Dec 14, 2010). This date i want to set as minimum date of my UIDatepicker. How can i do this please reply?

Thanks Nishant

Convert your UILabel text in to date format using NSDateFormatter and put that value replacing "Date" in following example:

UIDatepicker *datePicker;

NSDate *Date=[NSDate date];

datePicker.minimumDate=Date;

You can use NSDateFormatter and use setDateFormat method for setting Date format.

[formatter setDateFormat:@"MMM dd,yyyy"];

NSDate *date = [formatter dateFromString:lblDate.text];

datePicker.minimumDate=date;

 NSCalendar *calendar = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease];
        NSDate *currentDate = [NSDate date];
        NSDateComponents *comps = [[[NSDateComponents alloc] init] autorelease];
        [comps setYear:0];
        NSDate *maxDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0];
        [comps setYear:-5];
        NSDate *minDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0];

        [datePicker setMaximumDate:maxDate];
        [datePicker setMinimumDate:minDate];

it showing five year date.......

See the minimum time from the current date to one month:

NSDate* currentTime = [NSDate date];

[datePicker setMinimumDate:[currentTime dateByAddingTimeInterval:43200]];//min time +12:00 for the current date

[datePicker setMaximumDate:[currentTime dateByAddingTimeInterval:2592000]]; // max day (+ 30 )
