Can I provide a joining argument for the first argument of an objective c function?

Question

- (void)testThisFunction:joiningArgument1(id)argument1 {
    NSLog(@"%@", @"Hello: ");
}

This tutorial talks about how there are "joining arguments" which are exposed at the call site. However, when I try to create a joining argument for the first argument, then I get Expected method body error likely because it breaks the syntax.

Can I give the first argument a "joining argument" or is that not allowed? If it is allowed, what is the syntax?

Answer 1

In objective c you can't define a label for first Argument or parameter the convention for this is like:

- (void)testThisFunctionWithJoiningArgument1:(id)argument1 {
    NSLog(@"%@", @"Hello: ");
}

- (void)methodNameWithFirstParam:(id)firstParam secondPraram:(id)secondParam {
    NSLog(@"%@", @"Hello: ");
}
