Wie kann ich eine Symbolleiste über der Tastatur hinzufügen?

Ich habe UIToolBarprogrammgesteuert ein erstellt und ein hinzugefügt UITextField. Jetzt muss sich diese Symbolleiste über der Tastatur befinden, wenn ich in ein anderes Textfeld klicke.

UIToolbar *toolBar=[[UIToolbar alloc]initWithFrame:CGRectMake(0,400, 320, 60)];
[self.view addSubview:toolBar];

UITextField *txtView=[[UITextField alloc]initWithFrame:CGRectMake(0, 400, 260, 30)];
txtView.backgroundColor =[UIColor  grayColor];
txtView.placeholder=@"Address";
UIBarButtonItem *txtfieldItem=[[UIBarButtonItem alloc]initWithCustomView:txtView];
toolBar.items =[NSArray arrayWithObject:txtfieldItem];

UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, 50)];
numberToolbar.barStyle = UIBarStyleBlackTranslucent;
numberToolbar.items = [NSArray arrayWithObjects:
                               [[UIBarButtonItem alloc]initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelNumberPad)],
                               [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                               [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(doneWithNumberPad)],
                               nil];
[numberToolbar sizeToFit];
phonenumberTextField.inputAccessoryView = numberToolbar;

So schließen Sie die Tastatur ab:

[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];

Swift 3:

let numberToolbar = UIToolbar(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.width, 50))
numberToolbar.barStyle = UIBarStyle.Default
numberToolbar.items = [
            UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Plain, target: self, action: "cancelNumberPad"),
            UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil),
            UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: "doneWithNumberPad")]
    numberToolbar.sizeToFit()
    phonenumberTextField.inputAccessoryView = numberToolbar

Swift 4.2:

let numberToolbar = UIToolbar(frame:CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
numberToolbar.barStyle = .default
numberToolbar.items = [
UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(cancelNumberPad)),
UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil),
UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(doneWithNumberPad))]
numberToolbar.sizeToFit()
phonenumberTextField.inputAccessoryView = numberToolbar

...

@objc func cancelNumberPad() {
    //Cancel with number pad
}
@objc func doneWithNumberPad() {
    //Done with number pad
}

Sie müssen dies nicht mehr im Code tun.

1. Ziehen Sie UIView einfach in die obere Leiste der aktuellen Szene und passen Sie sie nach Ihren Wünschen an.

2. Im Code einfach IBOutletfür beide eingeben : toolbarViewund textViewund Verbindungen herstellen.

   @IBOutlet private var toolbarView: UIView!
   @IBOutlet private var textView: UITextView!
   

3. In der viewDidLoadEinrichtung Ihrer SymbolleisteView als ZubehörView Ihrer UItextView.

   override func viewDidLoad() {
       super.viewDidLoad()
   
       textView.inputAccessoryView = toolbarView
   }
   

Das Ergebnis lautet wie folgt:

Für schnelles (1.2):

let numberToolbar = UIToolbar(frame: CGRectMake(0, 0, self.view.frame.size.width, 50))
numberToolbar.barStyle = UIBarStyle.Default

numberToolbar.items = [
    UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Plain, target: self, action: "keyboardCancelButtonTapped:"),
    UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil),
    UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: "keyboardDoneButtonTapped:")]

numberToolbar.sizeToFit()
yourTextView.inputAccessoryView = numberToolbar

Sie können diesen Code verwenden, es funktioniert für mich.

-(void)viewdidload
{
 UIToolbar* keyboardDoneButtonView = [[UIToolbar alloc] init];
 [keyboardDoneButtonView sizeToFit]; 
 UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                        style:UIBarButtonItemStyleBordered target:self
                                                                  action:@selector(doneClicked:)];
  [keyboardDoneButtonView setItems:[NSArray arrayWithObjects:doneButton, nil]];
  textField.inputAccessoryView = keyboardDoneButtonView;
 }
-(void)doneClicked:(id)sender
{
NSLog(@"Done Clicked.");
[self.view endEditing:YES];
} 

Sie können die Eigenschaft UITextFields inputAccessoryView verwenden

    txtField.inputAccessoryView = toolBar;

Swift 3

    let toolBar = UIToolbar(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 50))
    toolBar.barStyle = UIBarStyle.default
    toolBar.items = [
        UIBarButtonItem(title: "Button1", style: UIBarButtonItemStyle.plain, target: self, action: #selector(test2)),
        UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil),
        UIBarButtonItem(title: "Button2", style: UIBarButtonItemStyle.plain, target: self, action: #selector(test1))]
    toolBar.sizeToFit()

    myTextField.inputAccessoryView = toolBar

textField.inputAccessoryView=[weakSelf addToolBar];
[textField setKeyboardType:UIKeyboardTypeNumberPad];

und fügen Sie eine Methode hinzu

-(UIToolbar *)addToolBar
{

    UIBarButtonItem *done=[[UIBarButtonItem alloc]initWithTitle:@"DONE" style:UIBarButtonItemStyleDone target:self action:@selector(done:)];
    UIToolbar *toolBar=[[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 30)];
    NSArray* toolBarItems=[[NSArray alloc]initWithObjects:done, nil];
    [toolBar setItems:toolBarItems];
    return toolBar;
}

Swift 5.0 und höher

           let toolBar = UIToolbar(frame: CGRect(x: 0.0,
                                                  y: 0.0,
                                                  width: UIScreen.main.bounds.size.width,
                                                  height: 44.0))//1
            let flexibleSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)//2
            let DoneButton = UIBarButtonItem(title: "Done", style: .plain, target: target, action: #selector(tapDone))//3
            toolBar.setItems([flexibleSpace, DoneButton], animated: false)
           textField.inputAccessoryView = toolBar
       // Done Action
        @objc func tapDone() {
           self.view.endEditing(true)
         }

In Swift 3 und 4

 let toolBar = UIToolbar()
 toolBar.barStyle = UIBarStyle.default
 toolBar.isTranslucent = true
 toolBar.isUserInteractionEnabled = true
 toolBar.sizeToFit()
 toolBar.items = [
        UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.plain, target: self, action: #selector(self.sendCodeBtnAction(sender:)))]

    tfPhone.inputAccessoryView = toolBar
