问题
In my app, I am getting two dates.
For Example,
1st Date : 28-10-2011
2nd Date : 2-11-2011
Now I want to all dates between this two selected date.
So it should be,
28-10-2011
29-10-2011
30-10-2011
1-11-2011
2-11-2011
How can I get this using NSDate?
回答1:
try dateWithTimeInterval:SinceDate:
NSMutableArray dates = [NSMutableArray array];
NSDate *curDate = startDate;
while([curDate timeIntervalSince1970] <= [endDate timeIntervalSince1970]) //you can also use the earlier-method
{
[dates addObject:curDate];
curDate = [MSDate dateWithTimeInterval:86400 sinceDate:curDate]; 86400 = 60*60*24
}
//here maybe an additional check if the enddate has to be inserted or not
回答2:
Look at NSDateComponents and dateByAddingComponents:toDate:options:, this is what I use and it works pretty good. Make sure to watch out for years that are leap years.
UPDATE: I would use thomas's example. It works better than mine and it is a lot easier to read.

You can convert your strings to NSDate objects using NSDateFormatter, then use NSDate's ealierDate: and laterDate: methods to compare them.
回答4:
NSDate *today = [NSDate date];
NSDate *startDate = [NSDate date];
NSDate *endDate = [today addTimeInterval:10.0*60.0*60.0*24.0]; // end date 10 days ahead
while (YES) {
startDate= [startDate addTimeInterval:1.0*60.0*60.0*24.0];
NSLog(@"%@ -- %@",endDate,startDate);
if([startDate compare:endDate]==NSOrderedDescending) break;
}
