例子:

NSString *year   = @"2011";
NSString *month  = @"1";
NSString *day    = @"2";
NSString *hour   = @"3";
NSString *minute = @"3";

NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
dateComponents.year   = [year intValue];
dateComponents.month  = [month intValue];
dateComponents.day    = [day intValue];
dateComponents.hour   = [hour intValue];
dateComponents.minute = [minute intValue];

NSDate *date = [[NSCalendar currentCalendar] dateFromComponents:dateComponents];
NSLog(@"date: %@", date);

NSLog输出:

date: 2011-01-02 08:03:00 +0000
