Add a button to hide keyboard

You can assign a toolbar with a button that dismisses the keyboard as the text field's inputAccessoryView. A quick example would be,

UIBarButtonItem *barButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:textField action:@selector(resignFirstResponder)] autorelease];UIToolbar *toolbar = [[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)] autorelease];toolbar.items = [NSArray arrayWithObject:barButton];textField.inputAccessoryView = toolbar;

Swift 2.0 version:

//Declared at top of view controllervar accessoryDoneButton: UIBarButtonItem!let accessoryToolBar = UIToolbar(frame: CGRectMake(0,0,UIScreen.mainScreen().bounds.width, 44))//Could also be an IBOutlet, I just happened to have it like thislet codeInput = UITextField()//Configured in viewDidLoad()self.accessoryDoneButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: #selector(self.donePressed(_:)))self.accessoryToolBar.items = [self.accessoryDoneButton]self.codeInput.inputAccessoryView = self.accessoryToolBar

Swift 4:

//Declared at top of view controllervar accessoryDoneButton: UIBarButtonItem!let accessoryToolBar = UIToolbar(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 44))//Could also be an IBOutlet, I just happened to have it like thislet codeInput = UITextField()//Configured in viewDidLoad()self.accessoryDoneButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.done, target: self, action: #selector(self.donePressed))self.accessoryToolBar.items = [self.accessoryDoneButton]self.codeInput.inputAccessoryView = self.accessoryToolBarfunc donePressed() {    //Causes the view (or one of its embedded text fields) to resign the first responder status.    view.endEditing(true)}

This can be done ways easier!

I made a custom view in IB, in my viewController.h I just made an IBOutlet UIView *accessoryView;, connected them and an - (IBAction)dismissKeyboard;

I put in the view a toolbar with a done button, made a connection to the IBAction an wrote:[textView resignFirstResponder] and

- (void)viewDidLoad{    textView.inputAccessoryView = accessoryView;    [super viewDidLoad];}

But actually that looks a bit strange and non-apple-style… Got an idea?
