How to make NSDateFormatter display locale
I am using NSDateFormatter to set my date in my iPhone app, and dates are showing up properly. However, I am finding all the locales (my app supports up to 12 different languages) are sticking to the date format I specify via setDateFormat. Ideally, I want the date format to appear in a form natural to the region setting for the user, instead of following my format (which works well for English but may not be natural for other locales).
Following is my code:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
[dateFormatter setDateFormat:@"MMMM dd, yyyy kk:mm:ss"];
self.creationDate.text = [dateFormatter stringFromDate:creationTimeStamp];
I would try the following NSDateFormatter API instead:
+ (NSString *)localizedStringFromDate:(NSDate *)date
dateStyle:(NSDateFormatterStyle)dateStyle
timeStyle:(NSDateFormatterStyle)timeStyle;
Like so:
self.creationDate.text = [NSDateFormatter localizedStringFromDate:creationTimeStamp
dateStyle:NSDateFormatterMediumStyle
timeStyle:NSDateFormatterShortStyle];
That should give you the output you're looking for, tidy up the code a little, and keep you from having to manage some spurious memory.
Found the solution. The key is to not call setDateFormat at all, and the API in iPhone would automatically pick the appropriate thing to display based on what is specified in setDateStyle and setTimeStyle .
Self-contained solution with @fbrereto's design:
static NSString *FormatDate(NSDate *date)
{
return [NSDateFormatter localizedStringFromDate:date
dateStyle:NSDateFormatterMediumStyle
timeStyle:NSDateFormatterNoStyle];
}
Now you can simply run:
NSString *formattedDate = FormatDate([NSDate new]);
