题目

请依照题目实作一个类：
类名：手机(Phone)
属性：颜色(_color),大小(_size),_cpu
行为：
查看本机信息(aboutMyPhone),
打电话(call),应该有参数，传入电话号码才能打电话。
发短信(sendMessage) 参数：电话号码和短信内容。

创建对象并测试。

1. 定义一个类

@interface Phone : NSObject
@end
@implementation Phone
@end

2. 属性

@interface Phone : NSObject
{
    NSString *_color;
    float _size;
    NSString *_cpu;
}
    
@end
@implementation Phone
@end

3. 无参数的方法声明和实现

@interface Phone : NSObject
{
    NSString *_color;
    float _size;
    NSString *_cpu;
}
 -(void)aboutPhone; 
@end
@implementation Phone
 -(void)aboutPhone
 {
     NSLog(@"颜色:%@ 大小%f CPU %@",_color,_size,_cpu);
 }
@end

@interface Phone : NSObject
{
    @public
    NSString *_color;
    float _size;
    NSString *_cpu;
}
 -(void)aboutPhone;
@end
@implementation Phone
 -(void)aboutPhone
 {
     NSLog(@"颜色:%@ 大小%f CPU %@",_color,_size,_cpu);
 }
@end




int main(int argc, char * argv[]) {
    Phone *iPhone = [Phone new];
    iPhone->_color = @"玫瑰金";
    iPhone->_cpu = @"A9";
    iPhone->_size = 4.7f;
    
    return  0;
}

3. 带一个参数的方法声明和实现

@interface Phone : NSObject
{
    @public
    NSString *_color;
    float _size;
    NSString *_cpu;
}
 -(void)aboutPhone;
-(void)callWithNumber:(NSString *)number;
@end
@implementation Phone
 -(void)aboutPhone
 {
     NSLog(@"颜色:%@ 大小%f CPU %@",_color,_size,_cpu);
 }
-(void)callWithNumber:(NSString *)number;
{
    NSLog(@"正在呼叫 %@",number);
    NSLog(@"对不起您拨的电话已停机。");
}
@end




int main(int argc, char * argv[]) {
    Phone *iPhone = [Phone new];
    iPhone->_color = @"玫瑰金";
    iPhone->_cpu = @"A9";
    iPhone->_size = 4.7f;
    [iPhone aboutPhone];
    [iPhone callWithNumber:@"110"];
    return  0;
}

3. 带多个参数的方法声明和实现

@interface Phone : NSObject
{
    @public
    NSString *_color;
    float _size;
    NSString *_cpu;
}
 -(void)aboutPhone;
-(void)callWithNumber:(NSString *)number;
-(void)sendWithMessage:(NSString *)msg toNumber:(NSString *)number;
@end
@implementation Phone
 -(void)aboutPhone
 {
     NSLog(@"颜色:%@ 大小%f CPU %@",_color,_size,_cpu);
 }
-(void)callWithNumber:(NSString *)number;
{
    NSLog(@"正在呼叫 %@",number);
    NSLog(@"对不起您拨的电话已停机。");
}
-(void)sendWithMessage:(NSString *)msg toNumber:(NSString *)number
{
    NSLog(@"正在向%@发送讯息：%@",number,msg);
    NSLog(@"发送成功！");
}
@end




int main(int argc, char * argv[]) {
    Phone *iPhone = [Phone new];
    iPhone->_color = @"玫瑰金";
    iPhone->_cpu = @"A9";
    iPhone->_size = 4.7f;
    [iPhone aboutPhone];
    [iPhone callWithNumber:@"110"];
    [iPhone sendWithMessage:@"今晚老地方见" toNumber:@"110"];
    return  0;
}
