How to convert a NSString to a NSDate with these formats:

Question

NSString *dateStr = "09/02/2015 04:51:00 p. m.";

I want to convert *dateStr to date with this format:

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"dd/MM/yy'"];

And make it look like this :

NSString *finalString = "09/02/2015";
