While converting NSString to NSDate?

Question

I try to convert NSString to NSDate with this code:

NSString *dateString=[[NSString alloc] init];
dateString = [[messageArray objectAtIndex:i] tim_dte];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"HH:mm,yyyy/MM/dd"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
msg.date = dateFromString;

But msg.Date is nil even if dateString shows the correct date string. What am I missing?

Answer 1

change this format

[dateFormatter setDateFormat:@"HH:mm,yyyy/MM/dd"];

into and try

[dateFormatter setDateFormat:@"yyyy/MM/dd HH:mm"];

Update

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy/MM/dd HH:mm"];
// use simple 
msg.date =   [dateFormatter dateFromString:@"2016/05/06 12:36"];
  NSLog(@"final date == %@",dateFromString);
//NSDate *dateFromString = [dateFormatter dateFromString:@"2016/05/06 12:36"];

// NSLog(@"final date == %@",dateFromString);

[dateFormatter setDateFormat:@"yyyy/MM/dd HH:mm"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
msg.date=dateFromString;

Try this code to convert NSString to NSDate

NSString *dateString = @"2016-05-06";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZ"];
NSDate *date = [dateFormatter dateFromString:@"2013-02-01T06:25:47Z"];
NSTimeZone *pdt = [NSTimeZone timeZoneWithAbbreviation:@"PDT"];
[dateFormatter setTimeZone:pdt];
[dateFormatter setDateFormat:@"HH:mm:ss zzz"];
[dateFormatter setDateFormat:@"K:mm a, z"];
NSString * updated String = [dateFormatter stringFromDate:date];
