How to send NSDate with a certain date format as NSNumber? i.e convert NSDate to NSDate with another format?

Question

I have two user selected dates: startDate and endDate. They are NSDate instances and I have to send them as parameters as NSNumbers. How can I convert them to NSNumber with seconds?

You mean NStimeInterval? then from there you can format the date — Joshua, Dec 22 '16 at 06:57
You shouldn't send raw date, because than you'll have problems with different time zones. — NSDmitry, Dec 22 '16 at 10:16

Use below code :

 NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
// set format however you want
[formatter setDateFormat:@"ddMMyyyy"];
NSDate *date = [NSDate date];
NSString *string = [formatter stringFromDate:date];
NSNumber *num1 = @([string intValue]);
NSLog(@"%@",num1);

I tried. It is taking the date as string in the form @"22/01/2016", but then when taken as int there is only 22 (int). – AbdulAziz Rustam Ogli Dec 22 '16 at 07:27
' NSDateFormatter *formatter = [[NSDateFormatter alloc]init]; dateFormat =SHORT_DATE_FORMAT; [formatter setDateFormat:dateFormat]; self.stringfr = [formatter stringFromDate:date]; self.startDate = @([self.stringfr intValue]);' – AbdulAziz Rustam Ogli Dec 22 '16 at 07:40
I hope I answered the way you expected. – AbdulAziz Rustam Ogli Dec 22 '16 at 07:41
Yes, exactly. only 22 out of string @"22/01/2016". – AbdulAziz Rustam Ogli Dec 22 '16 at 07:44
Let me check once – Himanth Dec 22 '16 at 07:46
Check my edited answer I'm getting exactly what you want – Himanth Dec 22 '16 at 07:48
sorry to say no. I think I should use NSTimeInterval. – AbdulAziz Rustam Ogli Dec 22 '16 at 08:15
Thank You for your time! – AbdulAziz Rustam Ogli Dec 22 '16 at 09:10

1) First, get the date in MM/dd/yyyy format:

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MM/dd/yyyy"];

2) get string date and remove '/' from it:

NString *string = [formatter stringFromDate:date];
NString *finalStr = [string stringByReplacingOccurrencesOfString:@"/" withString:@""];

3) Use NSNumberFormatter from converting NSString to NSNumber:

NSNumberFormatter *f = [[NSNumberFormatter alloc] init];
f.numberStyle = NSNumberFormatterDecimalStyle;
NSNumber *myNumber = [f numberFromString: finalStr];

Hope, this is what you want!

If you mean a timestamp format NSDate *date = [NSDate date]; NSTimeInterval ti = [date timeIntervalSince1970]; How to convert NSDate into Unix timestamp in Objective C/iPhone?

Thanks,
