Convert the string to date with proper format then change that date to string with the format you need.

Change the code as follows:

NSString *dateValue = self.selectedReward.expires_at;
NSLog(@"Date value --- %@", dateValue);
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; //change the format
NSDate *date = [formatter dateFromString:dateValue];
//add this:
[formatter setDateFormat:@"yyyy-MM-ss"];
NSString *dateStr = [formatter stringFromDate:date];
[cell.lblExpire setText:[NSString stringWithFormat:@"%@ %@",NSLocalizedString(@"lbl_Expired_On", nil),dateStr]];
NSLog(@"date %@", dateStr);

In your question, you have clearly mentioned the date format also then why are used the wrong format

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
//2018-10-15 15:37:00   
[formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSDate *date = [formatter dateFromString:dateValue];
NSLog(@"date %@", date);
[formatter setDateFormat:@"yyyy-MM-dd"];
NSString *getFinalDate = [formatter stringFromDate:dateValue];
NSLog(@"final Date %@", getFinalDate);

for more info see this sample output
