ARC下的NSString属性应该是强还是复制？ [英] Should an NSString property under ARC be strong or copy?

问题描述

当不使用ARC编译时，建议对 NSString 之类的数据类型使用 copy 属性。我找不到在ARC模式下使用 copy 的正确文档。有人能告诉我什么适用于ARC？

When not compiling with ARC, it is recommended to use copy properties for data types such as NSString. I could not find proper documentation on the use of copy in ARC mode. Can someone tell me what's applicable for ARC?

推荐答案

它仍然建议复制，因为你想避免一些通过可变字符串，然后更改它而不知道。复制保证您所拥有的字符串不会改变。

It is still recommended to copy because you want to avoid something passing a mutable string and then changing it without you knowing. A copy guarantees that the string you have will not change.
