这里是你的愿望输出代码： http://unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns

：

NSDate *chosen = [datePicker date]; 

NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; 
[formatter setDateFormat:@"EEE MMM dd hh:mm a"]; 

NSString *formated_date = [formatter stringFromDate:chosen]; 

NSLog(@"formated date is : %@", formated_date]; 

您可以通过阅读此链接更改日期的格式

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 
NSUInteger unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSWeekdayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit ; 
NSDateComponents *components = [gregorian components:unitFlags fromDate:yourPickerDate]; 
NSInteger yourWeekDay = [components weekday]; 

我认为这将是对你有所帮助。
