Changing State for an object in Cocos2d - cocos2d-iphone

Question

firstly i would like to apologise for being a complete novice but I have researched the web and can not find a solution to my current problem.
I have 3 objects (sprites) that i have set up individually with switch statements and want to use my main gameplay layer to change their states randomly to an animation that i have already defined in the objects individual header and implementation files.
I have set up a self schedule updater and arc4random method that works but it will not change the state of the object, as it only calls the CCLOG that I have also included in the statement.
I have listed to code below and i know it is a bit of a mess but still very much in my first steps of being a beginner, if anyone can point me in the right direction (that's if i have explained this in a way you can understand!) I would be very grateful.
Thanks in advance for even looking at this question.

Answer 1

Finally found out that all I needed was to add the following code to my TBT gameCharacters-(void)updateStateWithDeltaTime: method...
if (characterState == kStateTest) {
if (characterState != kStateTest) {
[self changeState:kStateTest];
return;
}
now it works fine.
Thanks again to Mikael for trying to help me.
