Question

I have tried so many things through the help I got, but I still can’t figure out how to do it properly. Here’s what I did lastly.

NSDateFormatter *tempFormatter = [[NSDateFormatter alloc]init];
[tempFormatter setDateFormat:@"dd-MM-yyy"];

NSDate *currentDate = [NSDate date];
NSDate *fromDate = [NSString stringWithFormat:@"%@",[tempFormatter stringFromDate:currentDate]];
NSLog(@"currentDate %@", fromDate);

NSDate *toDate = [NSString stringWithFormat:@"%@",[tempFormatter stringFromDate:datePicker.date]];
NSLog(@"toDate %@", toDate);

NSTimeInterval interval = [toDate timeIntervalSinceDate:fromDate];
double leftDays = interval/86400;
NSLog(@"Total interval Between::%g",leftDays);

Tell me what I did wrong. Is it the NSDate conversion, that I am not doing properly ??
Thanks.

This line is creating problem.

 NSDate *toDate = [NSString stringWithFormat:@"%@",[tempFormatter stringFromDate:datePicker.date]];

It changes the type of toDate from NSDate to __NSCFString. The NSTimeInterval take both of its arguments of NSDate type, but in your case only fromDate is NSDate type.

Change your code with these lines

NSDate *currentDate = [NSDate date];
    NSDate *toDate = datePicker.date;
NSTimeInterval interval = [toDate timeIntervalSinceDate:currentDate];

It will surely work (inshaAllah).
