Question

我以编程方式创建了UIToolBar，并在其上添加了UITextField。现在，当我点击另一个文本字段时，我需要将该工具栏放在键盘上方。

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];

Answer 1

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;

取消键盘：

[[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
}

您不再需要在代码中执行此操作。

只需将UIView拖到当前场景的顶部栏并根据需要自定义。

在代码中，只需为IBOutlet和toolbarView添加textView并建立连接。

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

在viewDidLoad中将您的toolbarView设置为UItextView的附件视图。

override func viewDidLoad() {
    super.viewDidLoad()

    textView.inputAccessoryView = toolbarView
}

结果如下：

您可以使用此代码对我有用。

-(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];
}

Answer 5

您可以使用UITextField的 inputAccessoryView 属性

    txtField.inputAccessoryView = toolBar;

Answer 6

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

Answer 7

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

并添加方法

-(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;
}

Answer 8

Swift 5.0 及更高版本

 String[] possibleCameraIDs = {"0", "1", "2", "3", "4", "5", "6", "7", "8"};

Answer 9

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
