Weird ViewControllers - iPhone SDK

Question

Hello everyone,

I have a Tab-Bar Application for this iPhone application I am making. I make a simple button on the 3rd view (3rd tab), and give it an IBAction to give an alert view. When I press build and go, everything works out fine. I go onto the 3rd tab, and I press my button. It simply crashes... Why is this happening? Everything I put in this 3rd tab crashes. I create a simple view controller, and write the class files to start over, but I keep getting the same errors.. Everything works fine on my first tab, where I originally got the first view controller..

P.S> It also says Incomplete Implementation of Class 'ThirdViewController'. I don't know why its there..

If anyone can help me out here, i would greatly appreciate it.

Answer 1

It's and UIAlertView, right ? This class requires the implementation of the protocol UIAlertViewDelegate and the method alertView:clickedButtonAtIndex: to handle the button click, that's why the compiler tell you that it's incomplete.

Anyway i expirienced some problems on the UIAlertView the first time i used it. My issues was on the otherButtonTitles parameters, the list must be terminated by nil, like this:

[myAlert initWithTitle:@"title" message:@"body " delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"ok",@"ignore",@"retry",nil];

Anyway, you can find useful debug about the crash into your console, try to post it here.
