(Swift&OC)UItextViewの使い方
13689 ワード
一、キーワード 1.1.弾性方向 1.2.UITExtViewキーボードをスライドして 1.3.入力ボックスにコンテンツがあるかどうか である. 1.4. UItextViewにview を追加 1.5. カスタムキーボード 1.6.キーボードのお知らせ(アニメーションのリズム設定)については、次のコードコメントをご覧ください. UIViewアニメーションの本質はコアアニメーションなので、コアアニメーションにアニメーションのリズムを設定することができます
二、Swiftでの使用 2.1.キーボードに を追加 2.2.カスタムキーボード(JKTextViewControl) を切り替えます.
三、OCでの使用 3.1.キーボードに を追加 3.2.カスタムキーボード(TestView Control) を切り替えます.
