键盘没有响应resignFirstResponder

Question

当选择textField时,我想显示一个弹出窗口,而不是显示键盘(我的代码位于底部).如果键盘没有显示,那么一切都很好.但是,如果键盘显示然后选择了文本字段,键盘就不会被解雇,某个地方的第一个响应者必须迷路但我不知道在哪里.有人有解决方案吗？

我的文字字段:

    self.startDateTextField = [[UITextField alloc] initWithFrame:CGRectMake(79, 148, 138, 27)];
[self.startDateTextField setBorderStyle:UITextBorderStyleRoundedRect];
[self.startDateTextField setDelegate:delegate];
[self.startDateTextField addTarget:delegate action:@selector(editStartDate:) forControlEvents:UIControlEventEditingDidBegin];
[popoverWrapper addSubview:self.startDateTextField];

在editStartDate:我有:

-(void)editStartDate:(UITextField *)textField {

[textField resignFirstResponder];

DatePickerVC *datePickerVC = [[DatePickerVC alloc] init];
datePickerVC.delegate = self;

self.popoverController = [[UIPopoverController alloc] initWithContentViewController:datePickerVC];
[self.popoverController setDelegate:self];

[self.popoverController presentPopoverFromRect:CGRectMake(0, 0, 5, 5) inView:textField permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
}

Answer 1

这很容易做到,使用你的UITextFieldDelegate方法特别是UITextFieldShouldBeginEditing并返回NO并执行代码来显示popover.这样,键盘永远不会显示开始.

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
  [self.view endEditing:YES]; // added this in for case when keyboard was already on screen
  [self editStartDate:textField];
  return NO;
}

要使它工作,请确保将textField的委托设置为self(视图控制器),并在editStartDate方法中删除resignFirstResponder调用.
