blocks|key|1350145|text|您可以使用UITextInputTraits协议来实现此目的：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1350146|myInput.autoCorrectionType+=+UITextAutocorrectionTypeNo;|code-block|syntax|javascript|1350147|有关更多详细信息，请参阅here。|1350148|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UITextInputTraits_Protocol/Reference/UITextInputTraits.html#//apple_ref/occ/intfp/UITextInputTraits/autocorrectionType^0|5|H|0|0|C|4|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|Y|8|@]|D|@$9|Z|A|10|1|11]]|E|$]]|$1|M|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|N|$O|$5|P|Q|R|E|$S|T]]]]

You can use the <code>UITextInputTraits</code> protocol to achieve this:

<pre><code>myInput.autoCorrectionType = UITextAutocorrectionTypeNo;
</code></pre>

See <a href="http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UITextInputTraits_Protocol/Reference/UITextInputTraits.html#//apple_ref/occ/intfp/UITextInputTraits/autocorrectionType" rel="nofollow noreferrer">here</a> for more details.

blocks|key|1565704|text|Interface+Builder也有一个下拉字段来禁用此功能。由于您更有可能在界面构建器中创建文本字段，请在那里查找它。你可以在“更正”旁边的属性检查器中找到它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1565705|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The Interface Builder also has a dropdown field to disable this. As you're more likely to create textfields in the interface builder, look for it there. You can find it in the Attributes Inspector next to 'Correction'.

blocks|key|1565862|text|你也可以在故事板中选择“属性检查器”并在“更正”下选择：“默认”、“是”和“否”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1565863|📷|atomic|offset|length|1565864|1565865|​|1565866|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/04649dc304e80682ca725bf1e8e640e8.png|imageAlt|1|https://ask.qcloudimg.com/http-save/yehe-900000/f3fffd5b82b30c0625bf60160bd8950f.png^0|0|0|1|0|0|0|1|1|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@$E|W|F|X|1|Y]]|A|$]]|$1|G|3|C|5|D|7|Z|8|@]|9|@$E|10|F|11|1|12]]|A|$]]|$1|H|3|I|5|6|7|13|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q|R|-4]]|S|$5|M|N|O|A|$P|T|R|-4]]]]

blocks|key|1350445|text|在SwiftUI中，可以使用.disableAutocorrection(true)修改器。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1350446|Hiere是一个真实的例子：|1350447|VStack+{
++++TextField("title",+text:+$LoginModel.email)

++++++++.foregroundColor(.white)

In SwiftUI, you can use the <code>.disableAutocorrection(true)</code> modifier.
Hiere is a real life example:
<pre><code>VStack {
 TextField(&quot;title&quot;, text: $LoginModel.email)
 .autocapitalization(.none)
 .disableAutocorrection(true)
 .foregroundColor(.white)
}
</code></pre>

blocks|key|1566014|text|Swift+5：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1566015|这就是我如何在我的项目中实现电子邮件地址字段|1566016|private+let+emailTextField:+UITextField+=+{
++++let+tf+=+CustomTextField(placeholder:+"Email+address")
++++tf.keyboardType+=+.emailAddress
++++tf.autocorrectionType+=+.no++++++++//disable+auto+correction

++++return+tf
}()|code-block|syntax|javascript|1566017|CustomTextField是我的扩展类(这里不重要)|1566018|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Swift 5:
This is how I am achieving for email address field in my project
<pre><code>private let emailTextField: UITextField = {
 let tf = CustomTextField(placeholder: &quot;Email address&quot;)
 tf.keyboardType = .emailAddress
 tf.autocorrectionType = .no //disable auto correction
 tf.autocapitalizationType = .none //disable default capitalization
 return tf
}()
</code></pre>
CustomTextField is my extension class (not important here)

When I try to edit texts in my iPhone application (<code>UITextfield</code>), it auto-corrects my input.

Could you let me know how can I disable this?

当我尝试在iPhone应用程序(UITextfield)中编辑文本时，它会自动更正我的输入。你能告诉我怎样才能禁用它吗？
