核心数据整数要使用哪些整数类型 [英] Which integer types to use for Core Data integers

问题描述

核心数据具有int16，int32和int64。当以它们的NSNumber形式使用它们时，我应该使用NSInteger或int（以及它们各自的NSNumber方法numberWithInt，numberWithInteger）。我一直将int用于int16，将NSInteger用于int32，但我不知道这是否正确。我想澄清一下。

Core Data has int16, int32, and int64. When working with these in their NSNumber form should I use NSInteger or int ( and their respective NSNumber methods numberWithInt, numberWithInteger ). I have been using int for int16 and NSInteger for int32, but I don't know if this is correct. I would just like some clarification.

推荐答案

NSInteger至少为32位，与int一样。我永远不会使用int16，除非您需要代表一个简短的内容。

NSInteger is at least 32 bit, as is int. I wouldn't ever use int16, unless you need to represent a short.

NSInteger在64位运行时中也可以是64位...

NSInteger can also be 64 bit, in a 64bit runtime...
