*edit here is the complete project in a zip file. no Viruses from my end seeing how im uploading fro school. PLease feel free to look at the code but don't Steal it. Whouldnt be worth taking anyways (grumble amature coding)

Im sorry for any ambiguity through the title. Hello, my name is brad. im taking an xocde development class as an elective in college. for my final project i am creating a simple rpg style type game. this is where im running into errors. I have the first start screen which incompasses a FinalViewController.h .m and .xib file(a class view controller). when the first screen loads it prompts a view with two options(buttons). the first button loads a second class view controller(SaveViewController.h .m and .xib). This works fine. my Problem Occurs when i click another button in a diffrent view from the SaveViewController, which calls a method from FinalViewController.


heres some code Snipplets i think might be helpful?

From FinalViewController.m

//this is the method used to remove the save class view and load the //Homeworld class view. i know the method works because when i call it // from inside the FinalViewController it works sucessfully. However when i // try and call it from inside SaveViewController.

-(void)LoadHomeWorld{
    [saveViewController.view removeFromSuperview];
    [self.view insertSubview:homeWorldController.view atIndex:1];
}

heres the complete SaveView Controller .h and .m files

    }
    if([txtNewChar.text length]<=1){
        [finalViewController LoadHomeWorld];
    }
}
@end

WHAT HAPPENS HERE IS IN A VIEW CALLED createNewChar with a button(tapCreateNewChar) and a text box (txtNewChar). the finalViewController is an outlet linked to FinalViewController.

Am I missing something. I didn't see where you said what happens. Is there an error message, crash, or just nothing happens? What button are you specifically talking about and where is the code that it is connected to?

"my Problem Occurs when i click another button in a diffrent view from the SaveViewController, which calls a method from FinalViewController." I don't think that is considered to be normal. A view controller in iOS is used to take control of the whole screen. Calling a previous controller is possible but if you are dealing with a user interface item, you have to concerned what it is connected to, as in the previous controller, not the current one.

Although tempted to look at your code, I don't normally click on links random suggested by people I don't know.

    }
    if([txtNewChar.text length]<=1){
        [finalViewController LoadHomeWorld];
    }

the line
[finalViewController LoadHomeWorld];
this method is not working in this view.

I looked at all of your code..

It's coded in a style I don't personally prefer, but after reading it for a while and seeing what you are trying to accomplish these changes:

1) in SaveViewController.xib - delete the object in there that is a FinalViewController; it's not needed and creates an improper reference (it will instantiate a new FinalViewController rather then your FinalViewController you're attempting to work with).

2) In SaveViewController.m - in the method tapCreateNewChar change:

if([txtNewChar.text length]<=1){
        [finalViewController LoadHomeWorld];
    }

to

if([txtNewChar.text length]>=1){
        [finalViewController LoadHomeWorld];
    }

3) Open up FinalViewController.xib, right click on the ViewController-Save object, in the Outlets, link the FinalViewController to the File's Owner (which will tell it that the FinalViewController instance should be associated with its IVar)

I think that's all of the changes I made. appear to fix the problem. I'm attaching screen shots of the two changes in the xib files... I've also uploaded the screen I get to now after keying in a name (yes, that one button is off the screen so you'll need to adjust your nib a little...)
