Shortcuts in Objective-C to concatenate NSStrings

Question

Are there any shortcuts to (stringByAppendingString:) string concatenation in Objective-C, or shortcuts for working with NSString in general?

Answer 1

When building requests for web services, I find doing something like the following is very easy and makes concatenation readable in Xcode:

NSString* postBody = {
    @""
    @""
    @" "
    @"  "
    @"   test"
    @"  "
    @" "
    @""
};
