Question

如何创建NSDate今天的日期以及分别为5,0和0的小时,分​​钟和秒？即日期将是07/02/2010 05:00:00

Answer 1

//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];

沿着这些方向的东西应该可以解决问题.
