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];
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
}
