Objective-C基础课问题
因此，我对重新编程有点生疏，而且我似乎找不到一个很好的参考来理解我想要实现的目标的结构。 因此，言归正传，我正在研究创建 Class 对象，例如。
#import Assets.h
@interface MainRecord: NSObject {
Assets* assets;
...
}
...
@end
在类中拥有类对象，在 main 中创建该对象时是否需要初始化？ 我想确保为 MainRecord 创建的每个实例始终与其资产相关联。（将来这些将写入文件）所有这些主要是为了可读性以及向此类添加对象的方便性。
So I'm a bit rusty getting back into programming and I can't seem to find a good reference for understanding the structure for what I am trying to achieve. So, without further ado I am looking at creating and Class object such as.
#import Assets.h
@interface MainRecord: NSObject {
Assets* assets;
...
}
...
@end
Having a class object within a class, do i need to initialize when the object is created in main? I want to make sure each instance created for MainRecord will always be associated with it's Assets.(in the future these will be written to a file) All of which is mainly for readability and ease of adding objects to this class.

我建议阅读（至少部分内容）Objective-C 2.0 编程语言，Apple 发布的指南。 名为 “定义类” 的部分将回答你的大部分问题。
基本上，您不会在
main()中初始化实例变量——该类定义了处理其自身变量的方法。 （这是面向对象编程语言的常见做法。）在 Objective-C 中，你在-(id)init方法中初始化实例变量，并在-(void)dealloc方法中释放它们避免内存泄漏。 例如，请参阅 NSString。I recommend reading (at least parts of) The Objective-C 2.0 Programming Language, a guide published by Apple. The section called "Defining a Class" will answer the bulk of your questions.
Basically, you don't initialize instance variables in
main()— the class defines methods that handle its own variables. (This is common practice for object-oriented programming languages.) In Objective-C you initialize instance variables in an-(id)initmethod and release them in-(void)deallocmethod to avoid leaking memory. For example, see all the-initWith...methods in NSString.
