Combine string in objectivec

How do I concenate 2 strings in objective-c, like in VB.net you can just do "foo开发者_C百科" & "bar"

NSString *newString = [@"foo" stringByAppendingString:@"bar"];

If you're going to change your string frequently consider using its mutable variant - NSMutableString which allows to append strings without creating new instance:

NSMutableString *mutString = [NSMutableString stringWithString:@"foo"];
[mutString appendString:@"bar"];
