Objective-c: ccTouchesBegin End and Moved not Firing when using Custom Sprites - ios

Question

I have a Ship Class, in this Ship Class i have the methods ccTouchesBegin, ccTouchesEnd and ccTouchesMoved. But these methods never fire:
Here is the Ship Class:
//
// Ship.m
// Asteroids
//
// Created by trikam patel on 06/08/2014.
// Copyright 2014 trikam patel. All rights reserved.
//
#import "Ship.h"
#import "Helper.h"
#implementation Ship
// on "init" you need to initialize your instance
-(id)init:(NSString*)imageName :(NSMutableArray*)asteroids
{
if( (self=[super init:imageName]) ) {
asteroids = asteroids;
}
return self;
}
-(void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
for(UITouch *t in touches){
CGPoint point = [self convertTouchToNodeSpace:t];
if(allowedToMove){
if(hasShipHit){
if(!shiphit){
shiphit = [[CCSprite alloc] init];
CCSpriteBatchNode *spritesheet = [Helper setupAnimation:#"shiphit" :2 :shiphit];
[self addChild:spritesheet];
}
[shiphit setPosition:ccp([self position].x, [self position].y)];
[shiphit setPosition:ccp(point.x, point.y + 76)];
}else{
[self setPosition:ccp(point.x, point.y + 76)];
}
}
}
}
-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
for(UITouch *t in touches){
CGPoint point = [self convertTouchToNodeSpace:t];
NSLog(#"begin move ship");
if(hasShipHit){
int shipX = [shiphit position].x;
int shipY = [shiphit position].y;
if (CGRectContainsPoint(CGRectMake (shipX - 20.5, shipY - 96, 50, 50), point))
{
allowedToMove = true;
}
}else{
int shipX = [self position].x;
int shipY = [self position].y;
if (CGRectContainsPoint(CGRectMake (shipX - 20.5, shipY - 96, 50, 50), point))
{
allowedToMove = true;
}
}
}
}
-(void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
for(UITouch *t in touches){
CGPoint point = [self convertTouchToNodeSpace:t];
allowedToMove = false;
}
}
This is how the Ship Class gets used in the Parent:
self.isTouchEnabled = YES;
Background *backgorund = [[Background alloc] init:#"bg1.png"];
[self addChild:backgorund];
ship = [[Ship alloc] init:#"ship.png" :asteroidArray];
[ship setPosition:ccp(100, 100)];
[self addChild:ship];

Answer 1

Your ship class must enable touch processing so it respond to Touch methods such as TouchesBegan and TouchesEnded. If I got it correct, your Ship class is a custom CCSprite or something similar, so probably it won't have any isTouchEnabled property.
Use your touches methods in your Parent Layer and call your ship methods from there.
Something like...
-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
for(UITouch *t in touches){
CGPoint point = [self convertTouchToNodeSpace:t];
[ship methodForTouch:point];
}
}
Hope it helps :)
