1) How to use a storyboard for single app controller. I met a problem when decided to use static cells. They can't be implemented in .xib files, but only in .storyboard. Due to get over this you should do next: Create storyboard file and UITableViewController in his workspace. Choose class and ID. Where class is a custom UITableViewController class and ID is custom string. In parent ViewController use this code: UIStoryboard *appSettingsStoryboard = [UIStoryboard storyboardWithName:@"NKVAppSettings" bundle:nil]; NKVSettingsTVC *appSettingsTVC = [appSettingsStoryboard instantiateViewControllerWithIdentifier:@"appSettingsID"]; [self.navigationController pushViewController:appSettingsTVC animated:YES]; 2) Invisible elements in UITableViewCells It's very interestin g, that when you use UITableViewCell class's elements (like  textLabel ) and Custom inherited  UITableViewCell's class elements. So you should or

1) How to compare two folders in OSx. diff -rq '/firstFolderPath' '/secondFolderPath' In terminal; -rq means to search in subfolders and print short description.

In line's window type something like *.mm, *.h.

1) Xcode compilator revolution: Xcode 4: LLVM-GCC for default, but GCC still available. Xcode 4.2: LLVM 3.0 for default, GCC expropriated. Xcode 4.6: update to LLVM 4.2.  Xcode 5:  update to LLVM 5.0,  LLVM-GCC expropriated. GCC to LLVM transition completed. 2) How to integrate Unity into iOS app. https://github.com/armandsLa/ios-unity5-objc : Objective-C https://github.com/blitzagency/ios-unity5 : Swift https://github.com/keyv/iOSUnityVuforiaGuide https://bitbucket.org/jack_loverde/unity-5-vuforia-6-and-ios-native-integration 3) How send data between Unity and iOS app. http://alexanderwong.me/post/29861010648/call-objective-c-from-unity-call-unity-from Integration of Unity: 1) Скопировать папки Classes и Libraries (Create groups). Добавить Data (Create folder references); 2) Удалить ссылки на все .h в папке Classes/Native и удалить папку Libraries/libil2cpp (Remove references); 3) Изменить код в UnityAppController.h; inline UnityAppController* GetAppCont
