ios - 使用 Swift 在 Today Extension(小部件)中显示警报
<p><p>我有一个 Today Extension，我有一个文本字段和按钮，我想做的是 <code>if textfield.hasText == true</code> 做一些事情和 <code>if textfield.hasText == false</code> 然后我想在小部件中显示警报</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>首先，<strong>iOS Extensions</strong>中不允许<strong>Keyboard Entry</strong>，所以在<strong>Today Widget</strong>中有一个<code>UITextField</code> > 没有任何意义。</p>
<blockquote>
<p>Because user interaction with Today widgets is quick and limited, you
should design a simple, streamlined UI that highlights the information
users are interested in. In general, it’s a good idea to limit the
number of interactive items in a widget. In particular, note that iOS
widgets don’t support keyboard entry.</p>
