ObjectiveC programming language provides a data structure called the array, which can store a fixedsize sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site ios objective c 2d array

I would think of a different implementation. Unless it is a demonstrable (i. e. you have measured and quantified it) performance issue, trying to store ObjectiveC objects in plain C arrays is often a code smell. The language used in iOS development is objective C. It is an objectoriented language and hence, it would be easy for those who have some background in objectoriented programming languages. In Objective C, the file where the declaration of class is done is called the interface file and the fileios objective c 2d array Where type can be any valid ObjectiveC data type and arrayName will be a valid ObjectiveC identifier. A twodimensional array can be think as a table, which will have x number of rows and y number of columns. A 2dimensional array a, which contains three rows and four columns can be shown as below

HandsOn with iOS 12's New iPad Gestures. ios objective c 2d array If you want to use a NSArray, you need an ObjectiveC class to put in it hence the NSNumber requirement. That said, ObjC is still C, so you can use regular C arrays and hold regular ints instead of NSNumbers if you need to. Neither C nor ObjectiveC truly support 2D arrays. Instead, in either language, you can create an array of arrays. Doing this in C gives you the same effect as a 2D array of ints with 2 rows and 3 columns, or vice versa: For more information about object literals in ObjectiveC, see Working with Objects in Programming with ObjectiveC. In Swift, the NSArray class conforms to the protocol, which allows it to be initialized with array literals.
