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