如何在Objective-C中强制转换间接指针 [英] how to cast an indirect pointer in Objective-C

问题描述

我正在尝试在钥匙串上做一些工作，并且正在按照本教程此处 不幸的是，我在搜索钥匙串时遇到了以下错误

I am trying to do some work on my keychain and am following this tutorial here Unfortunately I am getting the following error where it talks about searching the keychain

Cast of an indirect pointer to an Objective-C pointer to 'CFTypeRef *' (aka 'const void **') is disallowed with ARC

这是代码的样子

 OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)searchDictionary,(CFTypeRef *)&result);

对于提供有关如何转换间接指针的正确代码的任何帮助，将不胜感激.

Any help providing the correct code on how to cast indirect pointer would be greatly appreciated.

使用void *代替:

Use void * instead:

 OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)searchDictionary,(void *)&result);
