iPhone用のデータを正しく表示していますが、iPadのデータを表示していないXcode Universal Storyboardプロジェクトがあります。以下のコードを使用してデータ配列を初期化しました。[DetailViewController setDataController:]を解決しようとしています:インスタンスに送信された認識できないセレクタ
iPhoneで正常に動作しているが、iPadの中のデータを表示しないと、エラーを取得します。
-[DetailViewController setDataController:]: unrecognized selector sent to instance
これは、コンパイラが文句を言っているAppDelegate.m
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
MasterViewController *masterViewController = (MasterViewController *)[navigationController topViewController];
DataController *controller = [[DataController alloc] init];
masterViewController.dataController = controller;
splitViewController.delegate = (id)navigationController.topViewController;
} else {
// Create the data controller and pass it to the master view controller.
UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
MasterViewController *masterViewController = (MasterViewController *) [navigationController topViewController];
DataController *controller = [[DataController alloc] init];
masterViewController.dataController = controller;
}
ですここのDetailViewControllerはそのファイルです。
