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.
