pass in value in route group middle ware

To pass a value in a route group middleware in Objective-C, you can use the following steps:

1. Define a route group middleware function that takes a parameter for the value you want to pass. For example: objective-c void myMiddleware(NSString *value) { // Middleware logic here }

2. In your route group, use the dispatch_block_t type to define a block that calls the middleware function with the desired value. For example: objective-c dispatch_block_t middlewareBlock = ^{ myMiddleware(@"your value"); };

3. Add the middleware block to the route group using the addMiddleware: method. For example: objective-c [routeGroup addMiddleware:middlewareBlock];

By following these steps, you can pass a value in a route group middleware in Objective-C.
