A gold challenge solution


This one was great. I tried to figure this out on my own before and did not find NSdateFormatter.

There is a little extra code in there as I was trying to figure out how to access the coordinate latitude and longitude. Ignore that.

[code]-(void)foundLocation:(CLLocation *)loc
CLLocationCoordinate2D coord = [loc coordinate];

/* __________________________________________________________
 If you want to print out the current latitude and longitude.
 This is how you access members of the "coord" structure, which
 hold double (float) values.  Therefore use %f, and it works.
  NSLog(@"The current latitude is %f.", coord.latitude);
  NSLog(@"The current longitude is %f.", coord.longitude);
___________________________________________________________ */

//Create an instance of BNRMapPoint with the current data

//Get the current date and time.
NSDate *today = [NSDate date];

//Set up a date formatter.
NSDateFormatter *dFormatter = [[NSDateFormatter alloc] init];
[dFormatter setTimeStyle:NSDateFormatterNoStyle];
[dFormatter setDateStyle:NSDateFormatterMediumStyle];

//Get the current date string using the formatter.
NSString *dateString = [@": " stringByAppendingString:[dFormatter stringFromDate:today]];

//To the title and the colon, add the date string.
NSString *outputString = [[locationTitleField text] stringByAppendingString:dateString];

BNRMapPoint *mp = [[BNRMapPoint alloc] initWithCoordinate:coord title:outputString];

//Add it to the map view
[worldView addAnnotation:mp];[/code]

I wanted to go a step further and also put in the latitude and longitude on the map point title, but it’s too long. I’m not sure whether such a title can have multiple lines.

It works, but I doubt that it’s the way it should be done. Seems like a lot of lines of code to get a string!
