Sprite disappearing when I am trying to move it - iphone

Question

Im trying to get my sprite to move on touch but seems to disappear on touch then reappear on second touch . I do not know how to fix this to get my sprite to move at the direction I tap. I have been trying to figure this out for a while but seems I am out of luck. I am hoping someone can point me at the right direction.
CGSize winSize = [[CCDirector sharedDirector] winSize];
player = [CCSprite spriteWithFile:#"Player.png"
rect:CGRectMake(0, 0, 27, 40)];
player.position = ccp(player.contentSize.width/2, winSize.height/2);
[self addChild:player z:1];
(void) registerWithTouchDispatcher
{
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self
priority:0 swallowsTouches:YES];
}
-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
return YES;
-(void)setPlayerPosition:(CGPoint)position {
player.position = position;
}
-(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
{
CGPoint touchLocation = [touch locationInView: [touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation];
touchLocation = [self convertToNodeSpace:touchLocation];
CGPoint playerPos = player.position;
CGPoint diff = ccpSub(touchLocation, playerPos);
if (abs(diff.x) > abs(diff.y)) {
if (diff.x > 0) {
playerPos.x += contentSize_.width;
} else {
playerPos.x -= contentSize_.width;
}
} else {
if (diff.y > 0) {
playerPos.y += contentSize_.height;
} else {
playerPos.y -= contentSize_.height;
}
}

The syntax of your touch function seems to be different.
try this code instead
- (void) ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint touchLocation = [touch locationInView: [touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation];
CGPoint playerPos = player.position;
}
