我想从函数的竞争中获取变量,并将其变成全局变量。这是我打电话的功能: func getJsonFromUrl(name: String, completion: @escaping (String?)->()) {
//use name variable just as you would in a normal function
let URL2 = "https://url.com/asd
我碰到过这样的伎俩来定义一个全局数组: // This template utilizes the One Definition Rule to create global arrays in a header.
template<typename unused=void>
struct globals_struct
{
static const uint8 s_str_seria
