Using @[array, of, items] vs [NSArray arrayWithObjects:]

by

They are almost identical, but not completely. The Clang documentation on Objective-C Literals states:

Array literal expressions expand to calls to
+[NSArray arrayWithObjects:count:], which validates that all objects are
non-nil. The variadic form, +[NSArray arrayWithObjects:] uses nil as
an argument list terminator, which can lead to malformed array
objects.

So

NSArray *myArray = @[objectOne, objectTwo, objectThree];

would throw a runtime exception if objectTwo == nil, but

NSArray *myArray = [NSArray arrayWithObjects:objectOne, objectTwo, objectThree, nil];

would create an array with one element in that case.
