resignFirstResponder 没有在 textFieldShouldReturn 上隐藏键盘 [英] resignFirstResponder not hiding keyboard on textFieldShouldReturn
问题描述
我有一个 UITextField 视图,当按下返回键时,它应该隐藏键盘.
I have a view with a UITextField which should hide the keyboard when return is pressed.
我的功能是这样的:
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
if ( textField == userPassword ) {
[textField resignFirstResponder];
}
return YES;
}
通常应该隐藏键盘,但它会保留在屏幕上.resignFirstResponder 被正确调用.我错过了什么?
Normally the keyboard should be hidden but it stays on the screen. resignFirstResponder is correctly called. What am I missing?
推荐答案
我看到你在这上面有 iPad 标签.您是否碰巧使用 UIModalPresentationFormSheet 呈现模态视图?如果是这样,看起来这是 FormSheet 模式演示的限制(Apple 出于某种原因有意这样做,或者它是一个错误).有关更多详细信息,请参阅这些其他问题:
I see you have the iPad tag on this. Do you happen to be presenting a modal view using UIModalPresentationFormSheet? If so, it looks like this is a limitation of the FormSheet modal presentation (either Apple is doing it intentionally for some reason, or it is a bug). See these other questions for more details:
