Perform SpriteKit Physics Body Collision/ Contact on touch End - ios7

Question

I am having some physics body nodes. Sprite Kit immediately calls didbegincontact method. I want that method should be called when i release the touch so that it may perform actions when click was released instead of calling method immediately causing some action setting problems for me.
- (void)didBeginContact:(SKPhysicsContact *)contact
{ NSLog(#"%hhd", _touching);
if(_touching == NO)
return;
something here
}
- (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
_touching = YES;
NSLog(#"%hhd", _touching);
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
_touching = NO;
NSLog(#"%hhd", _touching);
something here
}

Answer 1

Set the global Variable, ie
BOOL _touching;
When you touch / release (touches ended and began) you set that var to YES / NO;
In the didbegincontact, use something like
if(_touching == YES) {
// what I want to happen when I am touching
}
else {
// i must not be touching so do this
}
Here is the basic set up - however I think its the game logic thats the issue, maybe think of a different way to solve your problem
#interface XBLMyScene()
#property (strong, nonatomic) SKNode *world;
#property (strong, nonatomic) SKSpriteNode *ball;
#property BOOL touching;
#end
#implementation XBLMyScene
-(id)initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
self.world = [SKNode node];
[self addChild:self.world];
self.backgroundColor = [SKColor colorWithRed:0.15 green:0.15 blue:0.3 alpha:1.0];
self.physicsBody = [SKPhysicsBody bodyWithEdgeFromPoint:CGPointZero toPoint:CGPointMake(500, 0)];
self.ball = [SKSpriteNode spriteNodeWithColor:[SKColor redColor] size:CGSizeMake(40, 40)];
self.ball.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:CGSizeMake(40, 40)];
self.ball.position = CGPointMake(200, 300);
[self.world addChild:self.ball];
self.touching = NO;
}
return self;
}
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
self.touching = YES;
}
-(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
self.touching = NO;
}
- (void) didSimulatePhysics
{
if (self.touching) {
NSLog(#"I am touching");
}
else {
NSLog(#"I am not touching");
}
}
