Objective-c Agent

1. Agent First Knowledge

Suppose the boss needs to buy a computer for the worker to buy

The boss needs an agent to buy a computer for the worker.

Boss creates a protocol protocol for the method of buying a computer

Bosses have a class of attribute properties that conform to the protocol

Boss has a member method method implementation for the agent to buy a computer

Worker classes need to follow protocol implementation protocol method buy a computer

The code is implemented as follows

 
 
 1 #import <Foundation/Foundation.h>
 2 #import "Boss.h"
 3 #import "Worker.h"
 4 
 5 int main(int argc, const char * argv[]) {
 6     @autoreleasepool {
 7 
 8         Boss * boss = [[Boss alloc] init];
 9         Worker * worker = [[Worker alloc] init];
10         [boss setDelegate:worker];
11         [boss delegateBuyMacbook];
12                 
13     }
14     return 0;
15 }
