模态对话框不会关闭键盘

我遇到了一个问题，当在一个 UITextField 或 UITextView 中留下键盘时，键盘不会被解雇 UIModalPresentationFormSheet 。另外，我创建了一个大按钮作为视图的背景，因此如果用户点击字段之外它会被触发。我在常规视图控制器中使用相同的代码，它按预期工作。在模态视图控制器中它什么都不做。任何建议都将不胜感激。

I am running into an issue where the keyboard does not get dismissed when leaving a UITextField or UITextView in a UIModalPresentationFormSheet. In addition, I've created a large button to serve as the view's background so if the user taps outside the fields it gets triggered. I am using the same code in a regular view controller, and it works as expected. In the modal view controller it does nothing. Any suggestions would be appreciated.

- (BOOL)textFieldShouldReturn:(id)sender { [titleTextField resignFirstResponder]; return YES; } - (BOOL)textViewShouldReturn:(id)sender { [synopsisTextView resignFirstResponder]; return YES; } - (IBAction)textFieldDoneEditing:(id)sender { [sender resignFirstResponder]; } - (IBAction)textViewDoneEditing:(id)sender { [sender resignFirstResponder]; } - (IBAction)backgroundClick:(id)sender { [titleTextField resignFirstResponder]; [synopsisTextView resignFirstResponder]; }

推荐答案

覆盖 disablesAutomaticKeyboardDismissal 返回NO，如下所示修复了我的同样问题。您应该将此代码放入视图控制器，从中启动键盘：

Overriding disablesAutomaticKeyboardDismissal to return NO as below fixed the same problem of mine. You should put this code to your view controller, from which you initiate the keyboard:

- (BOOL)disablesAutomaticKeyboardDismissal { return NO; }
