Disable editing of a text field
提问by Greg
I want to start by saying this is my first project and I am trying hard to find answers myself before posting here. I thought I had found the code to accomplish this. I have no errors but when I run, the field is still editable. So, how can I disable editing of my field when the rule I have set is true?
我想首先说这是我的第一个项目，我正在努力寻找答案，然后再在这里发帖。我以为我已经找到了实现这一点的代码。我没有错误，但是当我运行时，该字段仍然是可编辑的。那么，当我设置的规则为真时，如何禁用编辑我的字段？
if sport.count == 1 {
enterSport.text = sport[0] as String //need to convert to a string
enterSport.editing; false //do not allow editing
} else {
//do nothing
}
I have defined the array previously so the if statement is true. Thank you for you assistance.
我之前已经定义了数组，因此 if 语句为真。谢谢你的帮助。

enterSport.userInteractionEnabled = falseinstead of editing.
enterSport.userInteractionEnabled = false而不是editing.
editingis a read-only property to indicate if the field is currently being edited or not.
editing是一个只读属性，用于指示当前是否正在编辑该字段。

If it's a UITextView, it has an editable property which you can set to false.
如果它是一个 UITextView，它有一个可编辑的属性，您可以将其设置为 false。
If it's a UITextField, you need to use the enabled property or the userInteractionEnabled property. Either of those will prevent editing. As
如果是 UITextField，则需要使用 enabled 属性或 userInteractionEnabled 属性。其中任何一个都会阻止编辑。作为

With Swift 3 Apple changed the property userInteractionEnabledto isUserInteractionEnabled.
在 Swift 3 中，Apple 将该属性更改userInteractionEnabled为isUserInteractionEnabled.
The code looks like this:
代码如下所示：
textfield.isUserInteractionEnabled = true
textfield.isUserInteractionEnabled = true
