在iPhone中显示UIDatePicker的工作日

Question

我希望以下格式显示UIDatePicker中的选定日期。这怎么可能？请帮我 格式为：Sat Feb 23 3:42 PM

Answer 1

以下是您希望输出的代码：

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];

您可以通过阅读以下链接更改日期格式： 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];

我认为这会对你有所帮助。

Answer 3

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

Answer 4

我明白了......

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

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

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