Converting an NSString result from SQLite into a formatted NSDate - objective-c

Question

I know that it sounds incessantly familiar, but most of the suggested solutions on SO have not worked for me for some strange reason.
I have a date string returned from an SQLite query as an NSString in this format:
2019-06-10 13:45:33
However, when any of the suggested date formatter solutions are applied, with or without timezone localisation, I keep getting such a result:
Mon Jun 10 13:45:33 2019
This is one of the routines I've tried, among many others:
NSString * dateString = #"2019-06-10 13:45:33";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
//[dateFormatter setDateFormat:#"YYYY-MM-dd HH:mm:ss"];
//[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss ZZZ"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
// dateFromString > Mon Jun 10 13:45:33 2019
Could I be doing something wrong or is there some missing step in the conversion?
TIA.

Answer 1

I could guess that you wanted another output format, if it is the case then you could try code like this:
NSString * dateString = #"2019-06-10 13:45:33";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
//[dateFormatter setDateFormat:#"YYYY-MM-dd HH:mm:ss"];
//[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss ZZZ"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
NSDateFormatter *printDateFormatter = [[NSDateFormatter alloc] init];
printDateFormatter.dateStyle = NSDateIntervalFormatterMediumStyle;
printDateFormatter.timeStyle = NSDateIntervalFormatterMediumStyle;
NSLog(#"%#", [printDateFormatter stringFromDate:dateFromString]);
The result will be:
10 Jun 2019 at 13:45:33

Answer 2

Use a different formatter to format the string from the date. For example:
NSDateFormatter * formatter=[[NSDateFormatter]alloc]init];
formatter.dateStyle = NSDateFormatterMediumStyle;
formatter.timeStyle = NSDateFormatterNoStyle;
NSString * formattedDateString = [formatter stringFromDate:date];
setDateFormat is for inputting date strings and getting NSDates.
dateStyle and timeStyle is for formatting dateStrings from NSDates.
