作成したUIViewControllerを追加しようとしているのですが、画面サイズの半分にしたいです。
私はこのコードを使用しています：
myController *tmController = [[myControlleralloc] initWithNibName:@"myController" bundle:nil];
tmController .view.frame = CGRectMake(10, 100, 100, 100);
[appDelegate.viewController presentModalViewController:tmController animated:YES];
しかし、すべての画面に表示されます。私のコードはどうなっていますか?
こんにちは、カテゴリファイルでこれを達成できます.....
