<p>如果使用开关，是否可以只禁用最后两个组件？如果是这样，我该怎么做？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您不能禁用组件。不过，您可以尝试这些解决方案。</p>
<p>第一个解决方案:</p>
<pre><code>var selectedRow3 = 3
var selectedRow4 = 3
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
switch component {
case 3:
myPicker.selectRow(selectedRow3, inComponent: component, animated: true)
case 4:
myPicker.selectRow(selectedRow4, inComponent: component, animated: true)
default:
break
}
}
</code></pre>
<p>第二种解决方案:</p>
<pre><code>func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
switch component {
case 3:
return 1
case 4:
return 1
default:
return 10
}
}
</code></pre></p>
