show keyboard with toolbar on button clicked in ios - ios

Question

I know how to show keyboard accessory with UITextField.
textField.inputAccessoryView = keyboardToolBar;
But what if I don't have a UITextField but a button. How do I show a keyboard that has a toolbar?
The toolbar itself will contain a UITextField, which I will have to be first responder programmatically.
But how would that work?
Update
-(void)createKeyboardToolBar
{
self.keyboardToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 42)];
self.textField = [[UITextField alloc] initWithFrame:CGRectMake(8, 6, 250, 30)];
UIBarButtonItem *textBtn = [[UIBarButtonItem alloc] initWithCustomView:self.textField ];
UIBarButtonItem *postBtn = [[UIBarButtonItem alloc]initWithTitle:#"Post" style:UIBarButtonItemStyleBordered target:self action:#selector(postComment)];
[self.keyboardToolBar setItems: [NSArray arrayWithObjects:textBtn,postBtn,nil]];
self.textField.inputAccessoryView = self.keyboardToolBar;
}
So following the suggestions, I come up with the code above. But when I click the button that is supposed to make self.textField the first responder, the call is made, but the keyboard or the toolbar does not appear. (I use NSLog)

Answer 1

for your button add action as buttonClicked. so when you click on the button show keyboard by using becomeFirstResponder for your textfield.
- (void)buttonClicked {
[myTextField becomeFirstResponder];
}

Answer 2

Alloc the textfield,toolbar globally, and add it to the toolbar.
In the button action write the 'become firstresponder' for the textfield.
Here is the solution
- (IBAction)keyboardaction:(id)sender {
self.keyToolbar_.hidden=NO;
CGRect lframe = self.keyToolbar_.frame;
lframe.origin.y = [[UIScreen mainScreen] bounds].size.height-<keyboardheight>;
[self.entryTxfld_ becomeFirstResponder];
[UIView animateWithDuration:0.3
delay:0
options:UIViewAnimationOptionCurveEaseInOut
animations:^ {
self.keyToolbar_.frame = lframe;
}completion:^(BOOL finished) {
}];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
CGRect lframe = self.keyToolbar_.frame;
lframe.origin.y = [[UIScreen mainScreen] bounds].size.height;
[UIView animateWithDuration:0.6
delay:0
options:UIViewAnimationOptionCurveEaseInOut
animations:^ {
self.keyToolbar_.frame = lframe;
}completion:^(BOOL finished) {
}];
[textField resignFirstResponder];
return YES;
}
In the XIB for View add toolbar the bottom and to the toolbar added the textfield.For reference find the image.
