在特定的小時和分鐘創建今天的NSDate

Question

如何在今天的日期和分別爲5,0和0的小時，分​​鍾和秒期間分別創建NSDate？即日期將是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]; 

沿着這些線應該做的伎倆。
