如何在键盘上方添加工具栏？ [英] How can I add a toolbar above the keyboard?

问题描述

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。

I have created a UIToolBar programmatically and added a UITextField on it. Now, I need that toolbar to be above the keyboard when I click in another text field.

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];

推荐答案

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];

使用Swift：

Using Swift:

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

使用Swift最新版本：

Using Swift Latest version:

 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

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