Is there a more concise way to concatenate these strings in Cocoa?

Question

NSString *latitude = [[NSString alloc] initWithFormat:@"%g°", coordinate.latitude];
NSString *longitude = [[NSString alloc] initWithFormat:@"%g°", coordinate.longitude];
self.pointLabel.text = [latitude stringByAppendingString:@", "];
self.pointLabel.text = [self.pointLabel.text stringByAppendingString:longitude];

Answer 1

self.pointLabel.text = [NSString stringWithFormat:@"%gº, %gº", coordinate.latitude, coordinate.longitude];

Answer 2

Yep.

self.pointLabel.text = [NSString stringWithFormat @"%g°, %g°", coordinate.latitude, coordinate.longitude];

Answer 3

Yes. Vote for me ;)

self.pointLabel.text = [NSString stringWithFormat @"%g°, %g°", coordinate.latitude, coordinate.longitude];

Answer 4

In addition to what the other three said, your code is leaking two objects. Please review the memory management rules.
