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];

NSString* latitude = [[NSNumber numberWithDouble:coordinate.latitude] stringValue]; // this will not leak as yours does. — kent

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

what is that symbol after the g?

Dave DeLong Over a year ago

@MarshallMoutenot option-0. It's the masculine ordinal indicator. It would probably be better to use shift-cmd-8, which is the actual degree sign.

Yes. Vote for me ;)

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

Yep.

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

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