<p><p>步骤 1. 用户在 textview 内部触摸时获取事件(您可以通过 <code>UITextView</code> 的委托(delegate)(<code>startEditing</code> 委托(delegate))获取)</p>
<p>步骤 2. 在你的 View 上添加一个 <code>UILabel</code>，给出用户在 textview 中触摸的位置，并将文本作为 textview 的文本，并将清晰的颜色作为背景色。 (在 textview 的委托(delegate)内执行此操作)</p>
<p>Step 3. Inside touches move of ur view会根据touches动态改变你标签的位置。</p>
<p>第 4 步。当用户移动其触摸直到删除 textview 委托(delegate)将被调用检查那里 <code>if(textview==droppingtextview)</code> 然后放 <code>draggingtextview.text=label.text</code> .并从 superview 中删除标签。</p></p>
