I am trying to use this plugin, but I am getting a blank screen when it loads. I get a couple errors that might not be related to this plugin, but I can't figure out what is wrong. I followed the instructions (GameKit framework, added code to navigationController, etc.). Here is the log below entries when I click the menu item that loads this plugin. I pulled the two ERROR lines out for clarity. Novice iOS coder. Any insights would be greatly appreciated. ++++++++++++++++++ 2013-05-31 22:28:31.159 testbuzz[4579:1fd03] BT_viewControllerManager: initViewControllerForScreen: ERROR, could not initialize view controller for screen with itemId: D0D8C247D235236D110C4BF 2013-05-31 22:28:31.159 testbuzz[4579:1fd03] BT_viewControllerManager: getErrorViewController ++++++++++++++++++ Full set of log entries when screen is loaded: +++++++++++++++++++++++++++ 2013-05-31 22:28:31.156 testbuzz[4579:1fd03] BT_screen_menuListSimple: didSelectRowAtIndexPath: Selected Row: 1 2013-05-31 22:28:31.156 testbuzz[4579:1fd03] BT_application: getScreenDataByItemId D0D8C247D235236D110C4BF 2013-05-31 22:28:31.157 testbuzz[4579:1fd03] BT_application: screenType is NAD_advanced_quiz for screen with nickname: "Advanced Quiz" and itemId: D0D8C247D235236D110C4BF 2013-05-31 22:28:31.157 testbuzz[4579:1fd03] BT_viewControllerManager: handleTapToLoadScreen 2013-05-31 22:28:31.157 testbuzz[4579:1fd03] BT_viewControllerManager: the parent screen nickname: "Home Screen Menu" itemId: F91C594A1D838FFEC9792EA itemType: BT_screen_menuListSimple 2013-05-31 22:28:31.157 testbuzz[4579:1fd03] BT_viewControllerManager: the menu/button tapped is itemId: 9899184858B6517AE4BF971 2013-05-31 22:28:31.157 testbuzz[4579:1fd03] BT_viewControllerManager: the screen to load is nickname: "Advanced Quiz" itemId: D0D8C247D235236D110C4BF itemType: NAD_advanced_quiz 2013-05-31 22:28:31.158 testbuzz[4579:1fd03] BT_viewControllerManager: initViewControllerForScreen nickname: "Advanced Quiz" itemId: D0D8C247D235236D110C4BF type: NAD_advanced_quiz 2013-05-31 22:28:31.159 testbuzz[4579:1fd03] BT_viewControllerManager: initViewControllerForScreen: ERROR, could not initialize view controller for screen with itemId: D0D8C247D235236D110C4BF 2013-05-31 22:28:31.159 testbuzz[4579:1fd03] BT_viewControllerManager: getErrorViewController 2013-05-31 22:28:31.159 testbuzz[4579:1fd03] BT_viewController: INIT 2013-05-31 22:28:31.159 testbuzz[4579:1fd03] BT_navigationController: pushViewController 2013-05-31 22:28:31.159 testbuzz[4579:1fd03] BT_navigationController: pushViewController for screen: D0D8C247D235236D110C4BF 2013-05-31 22:28:31.160 testbuzz[4579:1fd03] BT_screen_menuListSimple: viewWillDisappear in BT_viewController BASE CLASS 2013-05-31 22:28:31.160 testbuzz[4579:1fd03] testbuzz_appDelegate: supportedInterfaceOrientationsForWindow 2013-05-31 22:28:31.161 testbuzz[4579:1fd03] BT_viewController: canBecomeFirstResponder in BT_viewController BASE CLASS 2013-05-31 22:28:31.515 testbuzz[4579:1fd03] BT_viewController: viewDidAppear in BT_viewController BASE CLASS

And I did drop the BT_xyz folders into Xcode project already. I am able to display a Custom HTML/Text plugin screen from my basic app.

Just for giggles, I'd delete the 'reference' to the files, and re add them to the project. I understand what you've said; the plugins were added. But something looks off in the viewController, and if nothing else, it's a confirmation. It's a start anyway. Cheers! -- Smug

Things to check: Build settings set to ios 6? Using the latest version of the plugin, ver 1.3? As smug said the reference to the screen could be off. Maybe a typo. Screen shots of the control panel would be helpfull. And you could always send me a copy of your project files if you want me to look at it.

Thanks for the tips. I did verify that the plugins was not correct and redownloaded my code and added them into the Xcode project properly. So now I see the Interactive Quiz plugin is working fine now, but NAD Advanced Quiz still is not. So I dusted off my Xcode debugger skills, novice as they are, and poked around and found out some useful details. Here's the skinny... In BT_viewControllerManager.initiViewControllerForScreen, there is a few lines of code that attempt to get the Class object for the plugin. Here's that set of code: +++++++++++++++ //screenType required if([theClassName length] > 0){ Class theClass = NSClassFromString(theClassName); NSLog(@"theClass = %@", theClassName); if(theClass != nil){ if([theClass respondsToSelector:@selector(alloc)]){ theViewController = [[theClass performSelector:@selector(alloc)] initWithScreenData:theScreen]; return theViewController; } } }//screenType length +++++++++++++++ This line: Class theClass = NSClassFromString(theClassName); fails to get the class name so it is nil. My question is what would cause this? The plugin is in there. What else should I check for?

Are you downloading you files from buzztouch.com or a self hosted CP?

Does your Nad_advanced_quiz.h look like this? #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> #import "BT_viewController.h" @interface Nad_advanced_quiz : BT_viewController { } @end

It looks like the BT packager is downloading the wrong code for NAD_advanced_quiz.h and NAD_advanced_quiz.m Get the 'download self hosted package' zip file for this plugin from your CP. Swap the .m and .h files in the download for the files in Xcode. Let us know if that helps.

Yes, my .h file did look like that and replacing the .h/.m files with the self hosted versions worked - sort of. In the .m there was an "import BT_appDelegate.h", but the appDelegate in my project was called testbuzz_appDelegate (testbuzz = name of my project). So I replaced all references to BT_appDelegate with testbuzz_appDelegate and it works great. Not sure if that is a bug or not, but just a heads up. Also, in the docs for your plugin, it says to add some code to "line 151" but it appears that maybe that is not the correct line anymore because it is inside of a method. Maybe differences between BuzzTouch and self hoste? Not sure, I am still learning all about BuzzTouch. Thanks so much for your assistance. Able to move forward with the app now. Very nice. Feature Request: Provide option for a "next question" button after you answer the current question and allow an "explanation" to be displayed when the answer is wrong (and/or right). This would be instead of the time delay to show the next question. I might attempt to customize it in my project to do this as an excuse to learn more iOS coding. Great plugin. Thanks for your contribution. Cheers Craig

That feature has been requested a few times. I think it might be time to get started building it.

That would be sweet. I have an immediate need for it. Considering yourself "followed". ;)

Got another feature request (is there a proper place for this?). A way for the user to select the number of questions before the quiz instead of hard coding into the config. Another project I could try to to tackle myself with some custom code.

That can be done with a menu plugin. Use one of the codes to check out my NRC app. https://www.buzztouch.com/forum/thread.php?tid=97E00D4AC9808933A01870A&fid=06DB0BCB08E8888&sortColumn=FT.id&sortUpDown=&currentPage=1 It uses the Animated Circle menu to let the user choose a 5, 10, 20, 30, 40, or 50 question quiz.

Thanks nadthevlad - I have been needing to dig into the snippet keeper. I am sure I could make use of it in many ways. Thanks for the pointers. I will review the URL and your circle menu. Cheers.

I know why; it's the auto layout. Auto layout allows the xib (user interface) file to compress/stretch elements depending on the kind of device you're working on... But I don't know what to do about it. Nad will be along shortly; he'll be able to get his head around it... Cheers! -- Smug

Hey feraco, I sent you a PM.
