重写文字NSArray以在OS X 10.6的gcc上进行编译

Question

I got a suggestion here on SO to write this line: 我在这里有一条关于写此行的建议：

NSArray *files = @[url];

However my Xcode/gcc is outdated as I'm still using OSX 10.6. 但是我的Xcode / gcc已过时，因为我仍在使用OSX 10.6。

How do I rewrite this line so that it will compile? 我如何重写此行以便可以编译？

Answer 1

If you need to use the old style Objective-C syntax you would write: 如果您需要使用旧式的Objective-C语法，则可以编写：

NSArray *files = [NSArray arrayWithObjects:url, nil];

or just: 要不就：

NSArray *files = [NSArray arrayWithObject:url];

Look at the documentation for NSArray . 查看NSArray的文档。
