如何将ARC项目转换为非ARC？

As per my knowledge, I know that we use -fno-objc-arc flag to disable ARC for files that NOT support ARC in an ARC project.

据我所知,我知道我们使用-fno-objc-arc标志为ARC项目中不支持ARC的文件禁用ARC。

And also we can use -fobjc-arc flag to enable ARC for files support ARC in a Non-ARC project.

此外,我们还可以使用-fobjc-arc标志启用ARC,以便在非ARC项目中支持ARC文件。

But if I want to convert my ARC project(not particular file) to Non-ARC project, then how should I go ahead for the same?

但是,如果我想将我的ARC项目(非特定文件)转换为非ARC项目,那么我应该如何进行相同的操作呢?

Anyone please brief me about the same.

有人请介绍一下这个问题。

Thanks in Advance.

提前致谢。

You have to insert manual memory management method calls in the appropriate places. In general, every new, alloc, retain, copy and mutableCopy call shall be balanced by a release or an autorelease (the latter is mainly used in the case of return values), so, for example, the following ARC-enabled code:

您必须在适当的位置插入手动内存管理方法调用。通常,每个new,alloc,retain,copy和mutableCopy调用都应该通过release或autorelease来平衡(后者主要用于返回值),例如,以下启用ARC的代码:

MyClass *myObj = [[MyClass alloc] init];
[myObj doStuff];

OtherClass *otherObj = [[OtherClass alloc] init];
return otherObj;

should be something like this under MRC:

在MRC下应该是这样的:

MyClass *myObj = [[MyClass alloc] init];
[myObj doStuff];
[myObj release];

OtherClass *otherObj = [[OtherClass alloc] init];
return [otherObj autorelease];
