问题描述
XCode 接受它.但是当我内部设置属性时会应用保留(因为只读，但当我在类方法中初始化值时没有设置器在外面)?
XCode accepts it. But will retain be applied when I internally set the property (no setter outside since readonly but when I initialize the value in a class method) ?

推荐答案
这样做的原因是让您可以在类延续或类别中执行 @property (retain).如果您在外部属性上没有保留，您将收到有关属性不匹配的警告.
The reason to do this is to allow you to do @property (retain) in a class continuation or category. If you don't have the retain on the outer property, you will get a warning about the properties being mismatched.
