How to hide an iOS numeric keyboard - iphone

Question

I'm using a numeric keyboard for input from a UITextField. I noticed that Interface Builder has a return key property called "Done". When I select "Done" under the return key options, I do not see that a Done button is created on the numeric keyboard. I see the "Done" button on other keyboard types if I change it from a numeric keyboard to something else, but not when using a numeric keyboard.
I want to create a "Done" button on the keyboard which will hide the keyboard when pressed
I want to do this because of the amount of real estate the keyboard takes up
I'm very new to iOS development, so the easiest and least convoluted way to accomplish this goal would be appreciated
Thanks in advance!

Answer 1

The typical way of doing this is to assign a toolbar containing a button to the inputAccessoryView property of the text view.

Answer 2

I found this solution online but it implies making an image for your done button: http://www.neoos.ch/blog/37-uikeyboardtypenumberpad-and-the-missing-return-key
Also you can use the same method for getting the UIKeyboard view showed in the example and do the following, as per #Jim's suggestion:
UIToolbar *keyboardViewToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 206, 320, 44)];
UIBarButtonItem *keyboardDoneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(doneSettingDate)];
UIBarButtonItem *title = [[UIBarButtonItem alloc] initWithTitle:#"Enter Number" style:UIBarButtonItemStylePlain target:nil action:nil];
UIBarButtonItem *spacer1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
UIBarButtonItem *spacer2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
NSArray *barButtonItems = [[NSArray alloc] initWithObjects:spacer1, title, spacer2, pickerDoneButton, nil];
[keyboardViewToolbar setItems:barButtonItems];
And add that view to the keyboard view.
Also, as a separate suggestion considering you're just starting out. On iTunes U you can download the Developing Applications for iOS Stanford class, it's a very complete course on iOS development, available for free on the iTunes Store.

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
UIToolbar* KeyBoardToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
KeyBoardToolbar.barStyle = UIBarStyleBlackTranslucent;
KeyBoardToolbar.items = [NSArray arrayWithObjects:
[[UIBarButtonItem alloc]initWithTitle:[GlobalSettings GetTextBySelectedLocale:#"Done"] style:UIBarButtonItemStyleBordered target:self action:#selector(DismissKeyBoard)],
[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
nil];
[KeyBoardToolbar sizeToFit];
txtMessage.inputAccessoryView = KeyBoardToolbar;
}
Where txtMessage could be UiTextField or UITextView.
-(void)DismissKeyBoard{
[self.view endEditing:YES];
}
