@interface MyClass : NSObject {
MyObject *objecto;
}
I have an object that I declare as a private variable (I think this is how you do a private variable in objective c).
我有一个对象，我声明为一个私有变量（我认为这是你在目标c中做私有变量的方式）。
Do I have to retain and release it?
我必须保留并释放它吗？
For example if I have a function should I be retaining it as soon as it has been assigned? Should I be using properties to do this always?
例如，如果我有一个功能，我应该在分配后立即保留它吗？我应该一直使用属性吗？
initWithMyObject: MyObject *input
