FIrst store your data in NSString. And then convert your string to NSDate.

Answer 2

Convert NSDate to NSString and try to encode.

- (NSString *) changeDateToDateString :(NSDate *) date {      NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];     [dateFormatter setTimeZone:[NSTimeZone localTimeZone]];     NSLocale *locale = [NSLocale currentLocale];     NSString *dateFormat = [NSDateFormatter dateFormatFromTemplate:@"hh mm" options:0 locale:locale];     [dateFormatter setDateFormat:dateFormat];     [dateFormatter setLocale:locale];     NSString *dateString = [dateFormatter stringFromDate:date];     return dateString; }
