How do I represent it with date for "dd MMM yyyy", means "11 JUN 2019"?

Question

I have date string like this "11 June, 2019 16:35:21". When I try to convert the string to NSDate it returns nil.

NSString str =@"11 June, 2019 16:35:21";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat: @"dd MMM yyyy"];
NSDate *date = [formatter dateFromString:str];
NSString *string = [[formatter stringFromDate:date] uppercaseString];

Is there any other way to convert it? Or where I'm doing wrong?

Answer 1

use date format as like

 NSString str =@"11 June, 2019 16:35:21";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
NSLocale *locale = [[NSLocale alloc] 
                 initWithLocaleIdentifier:@"en_US_POSIX"];
[formatter setLocale:locale];
 // input dateformat      @"11 June, 2019 16:35:21";
[formatter setDateFormat: @"dd MMMM, yyyy HH:mm:ss"];
NSDate *date = [formatter dateFromString:str];
// output dateformat for e.g @"11 Jun 2019 
   [formatter setDateFormat: @"dd MMM yyyy"];
NSString *string = [[formatter stringFromDate:date] uppercaseString];
