使用KVC对person的属性进行赋值

[aperson setValue:@"yadong" forKey:@"name"];     [aperson setValue:@"man" forKey:@"sex"];     [aperson setValue:@23 forKey:@"age"];     NSLog(@"%@",[aperson valueForKey:@"name"]);  // aperson.name

使用键值路径复合赋值    // aperson setValue:<#(id)#> forKeyPath:<#(NSString *)#>

// 创建 person 对象    Person *aperson = [[Person alloc] init];    // 使用字典对person的属性进行赋值(熟练掌握)    NSDictionary *dic = @{                          @"name":@"yadong",                          @"sex":@"man",                          @"age":@22                          };    // 赋值    [aperson setValuesForKeysWithDictionary:dic];    NSLog(@"%@",aperson);

解析 plist 文件，主要看root。是什么建什么

NSString *patch = [[NSBundle mainBundle] pathForResource:@"Person" ofType:@"plist"];    NSArray *array = [NSArray arrayWithContentsOfFile:patch];    // NSLog(@"%@", array);    // 把字典转化为person模型    NSMutableArray *personArray = [NSMutableArray array];    for (NSDictionary *dict in array) {        Person *p = [[Person alloc] init];        [p setValuesForKeysWithDictionary:dict];        [personArray addObject:p];    }
