カントUIScrollViewのプログラム

Question

に私のすべてのビューを追加する方法を見つける**これは私がプログラムでUIを作った私のコードですが、私はそれができるようにスクロールさせることができないのです**

ここでは、私が試してみました私のコードです多くの方法は、プログラムでスクロールビューを追加しますが、それはplzは助けて働いていなかった

私はview.addSubView(MyViews Here)

のようにスクロールビューに追加しようとしまし作成したすべてのビュー

Here is the screen shot of my app

Answer 1

1. セットトップ制約、ボトム、先頭とスーパー
2. スーパービューは、コンテンツビューを作成し、トップ制約を設定スクロールビュー（view.addSubview（scrollView））
3. を追加参照ScrollViewに末尾、ボトム、先頭と
4. はコンテンツビュー内の要素を設定してスクロール表示が
5. ScrollView（scrollView.addSubview（contentView））へのコンテンツのビューを追加の参照コンテンツビューに後続

Answer 2

あなたの質問によると、あなたのビューの階層は次のようになります。

ビュー - > scrollView - > allYourViews

だから、あなたはあなたのscrollViewは、ビューと同じフレームに設定することができます

を

view.addSubView(scrollView) 
scrollView.addSubView(yourViews Here)
