Generating a String from CLLocationDegrees, e.g. in NSLog or StringWithFormat

Hello Stacked-Experts!

My question: How to generate a string from a CLLocationDegrees value?

Failed attempts:

1. NSLog(@"Value: %f", currentLocation.coordinate.latitude); //Tried with all NSLog specifiers.
2. NSNumber *tmp = [[NSNumber alloc] initWithDouble:currentLocation.coordinate.latitude];
3. NSString *tmp = [[NSString alloc] initWithFormat:@"%@", currentLocation.coordinate.latitude];

When I look in the definition for the CLLocationDegrees it clearly states that this is a double: 

typedef double CLLocationDegrees;

What am I missing here? This is making me go crazy... Please help to save my mind!

Thanks in advance and best regards. //Abeansits

Solution

  • These are correct:

    NSLog(@"Value: %f", currentLocation.coordinate.latitude); //Tried with all NSLog specifiers.
NSNumber *tmp = [[NSNumber alloc] initWithDouble:currentLocation.coordinate.latitude];

    This is wrong, because coordinate.latitude isn't an object as nsstring might expect. 

    NSString *tmp = [[NSString alloc] initWithFormat:@"%@", currentLocation.coordinate.latitude];

    If you want an NSString:

    myString = [[NSNumber numberWithDouble:currentLocation.coordinate.latitude] stringValue];

    or

    NSString *tmp = [[NSString alloc] initWithFormat:@"%f", currentLocation.coordinate.latitude];
