Xcode build issues and the sim only shows the splash/load screen??

In OurDesignsViewController.m - why define the interface again? Importing the header file at the top should be sufficient.

I was referring to the empty category

@interface OurDesignsViewController ()

@end

this is unnecesssary - though it's not the cause of your problems.

Yes, you do need to import the other header files. Your creating an instance of that class.

I assume you've connected your IBActions in interface builder?

the snippets you've provided look ok. - check your interface builder connections.

I notice in your first screen shot that an exception was thrown by your app.

try surrounding your UIApplicationMain call with a try catch block - e.g.

    int retVal =0;    @autoreleasepool{             @try{                      retVal =UIApplicationMain(argc, argv, nil, NSStringFromClass[AppDelegate class]);             }        @catch(NSException*exception){                      NSLog(@"Craig's exception - %@",[exception description]);                      exit(1);             }    }    return retVal;

Reading my post I see that I left out paranthesis

retVal =UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

sorry.
