Question

I’m declaring:

CCSprite+DisableTouch.h file

#import "cocos2d.h"

@interface CCSprite (DisableTouch) <CCTargetedTouchDelegate>  {

}

-(void)disableTouch;
-(void)enableTouch;

@end

And for the CCSprite+DisableTouch.m file

#import "CCSprite+DisableTouch.h"


@implementation CCSprite (DisableTouch)

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
    return YES;
}

-(void)disableTouch
{
    [[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:-1000 swallowsTouches:YES];
}

-(void)enableTouch
{
    [[CCTouchDispatcher sharedDispatcher] removeDelegate:self];
}

@end

why I get: Expected identifier or '(' before '{' token error?
How should I solve this one?

Answer 1

The error is by adding the { & } characters to your category, as categories cannot have iVars.

If you need an iVar with your category, consider using associated objects:

#import <objc/runtime.h>

...

objc_setAssociatedObject(self, @"iVar", @"value", OBJC_ASSOCIATION_ASSIGN);

...

id iVar = objc_getAssociatedObject(self, @"iVar");
