CFAutoRelease()在iOS6上的行为 [英] CFAutoRelease() -like behavior on iOS6

问题描述

我有一个创建ABRecordRef，设置其属性并返回ref的方法.

I have a method that creates an ABRecordRef, sets its properties and returns the ref.

使用CFAutoRelease时遇到崩溃，因为我需要支持iOS< 7.我将如何适当地释放它?

I'm encountering a crash when I use CFAutoRelease because I need to support iOS <7. how would I go about to properly releasing this?

-(ABRecordRef) myRecord{
 ABRecordRef newRecord = ABPersonCreate();
//some setting here
return CFAutoRelease(newRecord); //how to release here?
}

推荐答案

对于CoreFoundation引用，我实际上不会在您的 myRecord 方法中释放该引用.相反，我将定义接口，以使 myRecord 的调用方拥有引用并负责释放该引用.

For CoreFoundation references, I actually wouldn't release that reference in your myRecord method. Instead I would define the interface such that the caller of myRecord owns the reference and is responsible for releasing it.
