如何快速定义自定义本地化常量

Question

I am new to swift 2 . I know define macro in objective c as

#define MYAPPCLocalize(Key) NSLocalizedStringFromTable(Key, APP_DELEGATE.currentStrings, @"N/A")

But how can i declare like the same in swift . Please help me

Answer 1

From Apple's docs :

Declare simple macros as global constants, and translate complex macros into functions.

You can translate your code this way:

func MYAPPCLocalize(key: String) -> String {
  return NSLocalizedStringFromTable(key, APP_DELEGATE.currentStrings, "N/A")
}

Answer 2

I had same problem.

Actually in swift there no concept of Macros. If you want to create simple macro then you can create it with let keyword which treated as a macro or something like static variable(attribute).

If you want to create parameterised macro, then create func with parameters and return type.
