如何在键盘上方添加工具栏？

Question 1

我已经以UIToolBar编程方式创建并添加了一个UITextField。现在，当我单击另一个文本字段时，我需要该工具栏位于键盘上方。

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];

Question 2

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;

要关闭键盘：

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

斯威夫特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
}

Question 3

您不再需要在代码中执行此操作。

只需将UIView拖动到当前场景的顶部栏，然后根据需要对其进行自定义即可。

在代码中简单地把IBOutlet两个：toolbarView和textView并进行连接。

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

在viewDidLoad设置工具栏时，将其作为附件的附件UItextView。

override func viewDidLoad() {
    super.viewDidLoad()

    textView.inputAccessoryView = toolbarView
}

结果如下：

Question 4

快速（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

Question 5

您可以使用此代码为我工作。

-(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];
}

Question 6

您可以使用UITextFields inputAccessoryView属性

    txtField.inputAccessoryView = toolBar;

Question 7

迅捷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

Question 8

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

并添加一个方法

-(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;
}

Question 9

Swift 5.0及更高版本

           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)
         }

Question 10

在Swift 3和4中

 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
