How do I show the keyboard by default in UITextView?
提问by bpapa
I want to create a view that consists solely of a UITextView. When the view is first shown, by default, I'd like the keyboard to be visible and ready for text entry. This way, the user does not have to touch the UITextViewfirst in order to begin editing.
我想创建一个仅由UITextView. 当视图首次显示时，默认情况下，我希望键盘可见并准备好进行文本输入。这样，用户不必触摸第UITextView一个即可开始编辑。
Is this possible? I see the class has a notification called UITextViewTextDidBeginEditingNotificationbut I'm not sure how to send that, or if that is even the right approach.
这可能吗？我看到班级有一个通知，UITextViewTextDidBeginEditingNotification但我不确定如何发送，或者这是否是正确的方法。

to accomplish that just send the becomeFirstResponder message to your UITextField, as follows (assuming you have an outlet called textField, pointing to the field in question):
要完成此操作，只需将 becomeFirstResponder 消息发送到您的 UITextField，如下所示（假设您有一个名为 textField 的出口，指向相关字段）：
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[textField becomeFirstResponder];
}

In Swift
在斯威夫特
To automatically show the keyboard, to the following:
要自动显示键盘，请执行以下操作：
override func viewDidLoad() {
super.viewDidLoad()
// show keyboard
textView.becomeFirstResponder()
}
Notes
笔记
- This assumes that the text view is editable.
- Works for both
UITextViewandUITextField - To hide the keyboard use
textView.resignFirstResponder()
- 这假设文本视图是可编辑的。
- 适用于
UITextView和UITextField - 隐藏键盘使用
textView.resignFirstResponder()

Following worked fine for me using Swift
以下使用 Swift 对我来说效果很好
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
// Show keyboard by default
billField.becomeFirstResponder()
}
Key is to use the viewDidAppear function.
关键是使用 viewDidAppear 函数。
