Is there some literal dictionary or array syntax in Objective-C?

Question

It\'s always been possible to create NSArrays (and NSDictionaries/NSNumber) with vararg method calls, like:

[NSArray arrayWithObjects: @\"a\", @\"b\", @\"c\"         


        

Answer 1

NSNumber *intNumber1 = @42;
NSArray *array1 = @[@"foo", @42, @"bar", @3.14];
NSDictionary *dictionary1 = @{ @1: @"red", @2: @"green", @3: @"blue" };
