什么最能描述@property(.....)?那实际上有什么用? [英] What describes @property(.....) best? What's that actually good for?

问题描述

我想知道的是，它标记了一个"public"属性.并且它会自动创建setter和getter.但是当我没有那个属性时，我的财产是私有的吗?

All I think to know is, that it marks a property "public". And it creates setters and getters automatically. But when I don't have that, are my properties private?

这种技术"叫什么名字?为什么在属性"前面有一个@?

What's the name of this "technology"? Why's there an @ in front of "property"?

推荐答案

@property()类型prop_name只是向编译器创建两个方法的信号:

@property () type prop_name is just a signal to compiler to create two methods:

-(type)propName;

-(type) propName;

和

-(void)setPropName; //不是为只读属性创建的

-(void) setPropName; // Not created for readonly properties

在Objective-C中，所有方法都是公开的.这就是为什么所有属性也都公开的原因

In objective-C all methods are public. Let is why all properties are public too
