有没有办法在其属性/方法之一上引用自定义类对象？

For example I've got class:

比如我上课了：

@interface CustomClass: NSObject
    @property(nonatomic, readwrite) NSString *name;
    @property(nonatomic, readwrite) NSNumber *value;
    -(NSDictionary *)getDict;
@end

@implementation CustomClass
-(NSDictionary)getDict
{
    NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithDictionary: @{}];
    if(self.name) {
        dict[@"name"] = self.name;
    }
    if(self.value) {
        dict[@"value"] = self.value;
    }
    return dict;
}
@end

Then I create instance of that class:

然后我创建该类的实例：

CustomClass *obj = [[CustomClass alloc] init];
obj.name = @"Custom object";
obj.value = @1;

Is there a way to get the 'name' property or getDict method when refering to that object? Like

有没有办法在引用该对象时获取'name'属性或getDict方法？喜欢

NSLog(@"%@", obj);

will return for example only the 'name' property?

将仅返回'name'属性？

You should override description or debugDescription.

您应该覆盖description或debugDescription。

- (NSString *)description
{
   return self.name;
}

I've found a way (not sure if it's the right way): My custom class is subclass of marker class MySerializable. Now if I've got an array of my objects, for every item in array I check if its of kind MySerializable and change that object in array to [object getDict].

我找到了一种方法（不确定它是否正确）：我的自定义类是标记类MySerializable的子类。现在，如果我有一个对象数组，对于数组中的每个项目，我检查它是否类型为MySerializable并将数组中的该对象更改为[object getDict]。
