What does @[] mean?

I am looking at a tutorial and I am not sure what the line of code means:

self.objectsToShare = @[URL];

URL is an NSURL, and self.objectsToShare is an NSArray.

Solution

  • It is a shorthand syntax for array creation.

    Instead of:

    [NSArray arrayWithObjects:&URL count:1];
