有个Person类，有个Phone类，Person类想使用Phone类中打电话和发短信的方法
1、Phone.h Phone有kind和color属性 ，方法定义的时候将用到的参数都定义进去
1 #import <Foundation/Foundation.h> 2 3 @interface ZSPhone : NSObject 4 @property(strong,nonatomic)NSString *kind; 5 @property(strong,nonatomic)NSString *color; 6 -(void)call:(NSString *)name andWithColor:(NSString *)color andWithKind:(NSString *)kind andWithWhom:(NSString *)name2; 7 8 9 10 -(void)sendMessage:(NSString *)name andWithColor:(NSString *)color andWithKind:(NSString *)kind andWithWhom:(NSString *)name2; 11 @end
2、Person.m //导入Phone.h，Person类中定义一个usephone方法，调用Phone中的call方法和sendMessage方法
1 -(void)usephone{ 2 ZSPhone *phone=[[ZSPhone alloc]init]; //使用ZSPhone类创建对象 3 [phone call:@"小花" andWithColor:@"红色" andWithKind:@"小米" andWithWhom:@"虎哥哥"]; 4 [phone sendMessage:@"小花" andWithColor:@"红色" andWithKind:@"小米" andWithWhom:@"虎哥哥"];
