ios - 如何比较 NSUUID

Question

比较两个 NSUUID 的最佳(最少代码、最快、最可靠)方法是什么？

这是一个例子:

-(BOOL)isUUID:(NSUUID*)uuid1 equalToUUID:(NSUUID*)uuid2
{
    return ... // YES if same or NO if not same
}

Answer 1

来自 NSUUID 类引用:

Note: The NSUUID class is not toll-free bridged with CoreFoundation’s CFUUIDRef. Use UUID strings to convert between CFUUID and NSUUID, if needed. Two NSUUID objects are not guaranteed to be comparable by pointer value (as CFUUIDRef is); use isEqual: to compare two NSUUID instances.

所以只需使用以下内容:

-(BOOL)isUUID:(NSUUID*)uuid1 equalToUUID:(NSUUID*)uuid2
{
    return [uuid1 isEqual:uuid2];
}
