GOStack

GOStack is an implementation of an abstract data type Stack in Objective-C.

Using

First of all, you need to add the source files into your project and then import in the file that you want to use.

#import "GOStack.h"

The initialize of Stack have no parameter.

GOStack *stack = [[GOStack alloc] init];

Once initialized, you can push and pop.

// Inserts a new element on the top of the stack
- (void)push:(id)item;

// Remove and returns the item from the top of the stack
- (id)pop;

The others methos of GOStack

// Check if the stack is empty
- (BOOL)isEmpty;

// Check if the stack contains the item
- (BOOL)contains:(id)item;

// Inserts a new element on the bottom of the stack
- (void)insertAtBottom:(id)item;

// Returns the number of items in stack
- (int)numberOfElementsInStack;

I also created a category for NSMutableArray. This allow us to init a NSMutableArray with a Stack! To do this, we need to import the category #import "NSMutableArray+GOStack.h" and then initialize with the option:

NSMutableArray *mutableArray = [[NSMutableArray alloc] initWithGOStack:stackName];
