I got a suggestion here on SO to write this line:
NSArray *files = @[url];
However my Xcode/gcc is outdated as I'm still using OSX 10.6.
How do I rewrite this line so that it will compile?
If you need to use the old style Objective-C syntax you would write:
NSArray *files = [NSArray arrayWithObjects:url, nil];
or just:
NSArray *files = [NSArray arrayWithObject:url];
Look at the documentation for NSArray
.
