How can I create an NSDate with today's date and an hour, minutes, and seconds of 5, 0, and 0 respectively? I.e. the date will be 07/02/2010 05:00:00

推荐答案

//Gives us the current date
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [gregorian components:NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit fromDate:[NSDate date]];
[components setHour:5];
NSDate * date = [gregorian dateFromComponents:components];
[gregorian release];

沿着这些线的东西应该做的。

Something along those lines should do the trick.
