Are there any shortcuts to (stringByAppendingString:
) string concatenation in Objective-C, or shortcuts for working with NSString
in general?
For example, I’d like to make:
NSString *myString = @"This";
NSString *test = [myString stringByAppendingString:@" is just a test"];
something more like:
string myString = "This";
string test = myString + " is just a test";

An option:
[NSString stringWithFormat:@"%@/%@/%@", one, two, three];
Another option:
I’m guessing you’re not happy with multiple appends (a+b+c+d), in which case you could do:
NSLog(@"%@", [Util append:one, @" ", two, nil]); // "one two"
NSLog(@"%@", [Util append:three, @"https://stackoverflow.com/", two, @"https://stackoverflow.com/", one, nil]); // three/two/one
using something like
+ (NSString *) append:(id) first, ...
{
NSString * result = @"";
id eachArg;
va_list alist;
if(first)
{
result = [result stringByAppendingString:first];
va_start(alist, first);
while (eachArg = va_arg(alist, id))
result = [result stringByAppendingString:eachArg];
va_end(alist);
}
return result;
}
