有没有更简洁的方法来连接Cocoa中的这些字符串？

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];
