Hi there everyone please can some one help me, short story i built app with BT (thanks guys wicked site) i have been downloading project to Xcode to run and build on iPhone simulator and my iPhone 4s, it was just how i wanted it, and everything worked fine. i then went for the itunesconnect and started the upload etc etc. I've now gone back in to the BT app to look at my master piece and run in Xcode but it now won't load up at all and its also missing all its files that uploaded in to it. I've taken a look at the config txt and it reads just how the app should look i.e. images sounds documents etc etc, and the project now fails with a error that reads like this....Code Sign error: The identity 'iPhone Developer' doesn't match any valid certificate/private key pair in the default keychain .......can some one help me before my girlfriend kicks me out after spending loads of time in the office LOL.. its build for iOS iPhone system,

Hi @jmproperties, Short story is that you need Developer Certificates to run in simulator and test on your phone, and Distribution Certificates to upload to iTunes so everybody else can run it. The iTunes version has to be compiled with your Distribution Certificates. Here's a link that tells you everything you need to get past this : http://btugwiki.com/index.php/Code_Signing_Basics This tutorial was written by an exceptional member of this forum, @Stefan! Mark

wicked stuff all done, thank you very much. next problem is that the app build success with no failed parts but get 19 target errors all to do with some sort of coding problem for example it says things like ...................... //set the status bar style (assume default) [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault]; if([[BT_strings getStyleValueForScreen:theScreenData:@statusBarStyle:@] isEqualToString:@default]){ [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault]; [[UIApplication sharedApplication] setStatusBarHidden:FALSE animated:FALSE]; } if([[BT_strings getStyleValueForScreen:theScreenData:@statusBarStyle:@] isEqualToString:@solid]){ [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque]; [[UIApplication sharedApplication] setStatusBarHidden:FALSE animated:FALSE]; } if([[BT_strings getStyleValueForScreen:theScreenData:@statusBarStyle:@] isEqualToString:@transparent]){ [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent]; [[UIApplication sharedApplication] setStatusBarHidden:FALSE animated:FALSE]; } if([[BT_strings getStyleValueForScreen:theScreenData:@statusBarStyle:@] isEqualToString:@hidden]){ [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault]; [[UIApplication sharedApplication] setStatusBarHidden:TRUE animated:FALSE]; any ideas , thanks again in advance
