ios - 未声明的 NSAutorelease

Question

我尝试使用 cygwin 和 THEOS 构建一个 ios 应用程序

教程: https://sites.google.com/site/theostutorials/home

经过几次尝试，我成功地完成了教程。最后我只需要运行命令“制作包安装”

然后我卡住了...

CYGWIN 终端:

ron_000@Laptop-Ron ~/projects/hello3
$ make package install
/home/ron_000/projects/hello3/theos/makefiles/targets/Cygwin/iphone.mk:38: Deplo

有人知道我做错了什么吗？

感谢任何输入，

p.s我希望我以正确的方式使用代码块来解决这个问题......

Answer 1

难道你是用ARC(automatic reference counting)编译的？在这种情况下，docs说:
如果使用自动引用计数 (ARC)，则不能直接使用自动释放池。相反，您使用 @autoreleasepool block 。例如，代替:

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
// Code benefitting from a local autorelease pool.
[pool release];

你会写:

@autoreleasepool {
    // Code benefitting from a local autorelease pool.
}  

可以为单个文件禁用 ARC，请参阅 here .
