iPad popover textfield - resignFirstResponder不会关闭键盘
我有两个文本字段的电子邮件和密码。当在常规视图上显示字段时，以下代码可以正常工作，但是当它们在弹出窗口上时，resignFirstResponder不起作用（becomeFirstResponder工作）。两个字段都调用了textFieldsShouldReturn。
如果我错过了什么，有什么想法吗？
谢谢！
I have two text fields email and password. The following code works fine when the fields are presented on a regular view but when they are on a popover, the resignFirstResponder does not work (becomeFirstResponder works). textFieldsShouldReturn was called for both fields. Any idea if I am missing something? Thanks!
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
if (theTextField == email) {
[password becomeFirstResponder];
return NO;
}
[theTextField resignFirstResponder];
return NO;
}
检查这个问题：
覆盖 disablesAutomaticKeyboardDismissal 返回否，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;
}
