從iPhone的UIDatePicker顯示工作日

Question

我想從UIDatePicker按照以下格式顯示所選日期。這怎么可能？ 請幫助我格式是： Sat Feb 23 3:42 PM

Answer 1

這是您所需輸出的代碼：

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];

您可以通過閱讀以下鏈接來更改日期格式： http : //unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns

Answer 2

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];

我認為這將對您有所幫助。

Answer 3

NSDateFomatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setFormat:@"DDD MMM dd mm:ss aa"];
NSString *dateString = [dateFormatter stringFromDate:date];

Answer 4

我知道了....

NSDateFormatter * dateFormat = [[NSDateFormatter alloc] init];

[dateFormat setDateFormat：@“ EEE MMM dd hh：mm aa”]；

NSLog（@“格式為：％@”，[dateFormat stringFromDate：datePicker.date]）;
