cocoa - How do I make and use a Queue in Objective-C? -


I want to use a queue data structure in my objective program. In C ++, I used the STL queue, what is the equivalent data structure in Objective-C? How can I pop / pop the item?

Ben's version is a stack rather than a line, so I'm a little bit:

NSMutableArray + QueueAdditions.h

@interface NSMutableArray (QEdition) - dequeue (ID); - (zero) enqueue: (id) obz; @end

NSMutableArray + queueAdditions.m 

  @implementation NSMutableArray (QueueAdditions) // queues are first-in-first Generally, we remove the object from the head- (id) dequ {// if ([self calculation] == 0) return zero; // Avoid exceptions (Quinn) ID head objects = [auto-objectattackedx: 0]; If (headObject! = Zero) {[headObject retain] autorelease]; // So it is not dealloc'ed on removing [self-removal objectOtindex: 0]; } Return head object; } // Add on the queue tail (when people cut the line, no one likes it!) - (zero) enqueue: (id) an object {[self adjective: an object]; // This method automatically combines at the end of the array) @ and

Just want to use your new methods, and you want to call them like any other NSMutableArray methods.

Put on good luck and coating!
