I would like to show the name of day in my iPhone application and i don't found the solution. Thanks for help
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"EEEE"];
NSString *dayName = [dateFormatter stringFromDate:yourDate];
[dateFormatter release];
You get dayName
in the locale of the user.
(check Unicode standards for date formats samples)
I found it, the answer was :
NSDate *now = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"EEEE"];
NSLog(@"%@",[dateFormatter stringFromDate:now]);
Thanks
NSDate category
+ (NSString *)dayNameWith0Monday:(NSInteger)index {
static NSDateFormatter * DateFormatter = nil;
if (DateFormatter == nil) {
DateFormatter = [[NSDateFormatter alloc] init];
[DateFormatter setDateFormat:@"EEEE"];
[DateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
}
NSDate * day = [NSDate dateWithTimeIntervalSince1970:((4 * 24 * 60 * 60) + (24 * 60 * 60 * index))];
return [DateFormatter stringFromDate:day];
}
0 will always be Monday! in case you need such behaviour
Look at -[NSCalendar components:fromDate:].
A date by itself doesn't have a day, because it may have different days in different calendars (Gregorian, Chinese, etc.).
EDIT: actually, sorry. That's what you would do to get the day and work with it programmatically. If you only want to display the day, look at NSDateFormatter.
@Jilouc answer in Swift:
let formatter = DateFormatter.init()
formatter.dateFormat = "EEEE"
let date = Date.init() //or any date
let dayName = formatter.string(from: date)
有很多很好的日期和时间处理资源 - 这是我从github上学到的。
