在键盘将显示通知中，我尝试向键盘添加工具栏但没有运气，我无法添加
Please let me know
请告诉我
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for(int i = 0; i < [tempWindow.subviews count]; i++)
{
//Get a reference of the current view
keyboard = [tempWindow.subviews objectAtIndex:i];
//Check to see if the description of the view we have referenced is "UIKeyboard" if so then we found
//the keyboard view that we were looking for
if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES)
{
[keyboard addSubview:myToolbar];
}

I think, you want an inputAccessoryView.
我想，你想要一个inputAccessoryView。
Basically, you create a view and set it as a text field's or text view's input accessory view.
基本上，您创建一个视图并将其设置为文本字段或文本视图的输入附件视图。
[textField setInputAccessoryView:inputAccessoryView];

这是代码以防其他人需要它。在堆栈溢出时找到
- (void)viewDidLoad
{
[super viewDidLoad];
UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
numberToolbar.barStyle = UIBarStyleBlackTranslucent;
numberToolbar.items = [NSArray arrayWithObjects:
[[UIBarButtonItem alloc]initWithTitle:@"Clear" style:UIBarButtonItemStyleBordered target:self action:@selector(clearNumberPad)],
[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
[[UIBarButtonItem alloc]initWithTitle:@"Apply" style:UIBarButtonItemStyleDone target:self action:@selector(doneWithNumberPad)],
nil];
[numberToolbar sizeToFit];
numberTextField.inputAccessoryView = numberToolbar;

Simple solution for iOS 8 and 9.
适用于 iOS 8 和 9 的简单解决方案。
Init your textField, searchBaretc.
INIT你textField，searchBar等
customView- View that will stick at the top of the keyboard. DO not add it as a subview to hierarchy! Do not have to set any constraints or positions.
customView-将粘在键盘顶部的视图。不要将其作为子视图添加到层次结构中！不必设置任何约束或位置。
[searchBar setInputAccessoryView:self.customView];
- (BOOL)canBecomeFirstResponder{
return true;
}
- (UIView *)inputAccessoryView {
return self.customView;
}
If you need to let the customView at the bottom and not hide it after dismissing keyboard, add observer:
如果您需要让 customView 在底部而不是在关闭键盘后隐藏它，请添加观察者：
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardDidHideNotification object:self.view.window];
And method
和方法
- (void)keyboardDidHide:(NSNotification *)notification {
[self becomeFirstResponder];
}

if you want to add tool bar on the keyboard, you are right place. You can use BSKeyboard easly. Look at the implementation below;
如果你想在键盘上添加工具栏，你就是对的地方。您可以轻松使用 BSKeyboard。看下面的实现；
in .h file
在 .h 文件中
#import "BSKeyboardControls.h"
add delegates
添加代表
@interface ViewController : UIViewController <BSKeyboardControlsDelegate>
now jump the .m file , go to viewDidLoad. We will add textfield which i want to add tollbar
现在跳转 .m 文件，转到 viewDidLoad。我们将添加我想添加收费栏的文本字段
self.keyboardControls = [[BSKeyboardControls alloc] initWithFields:@[PINTextField]];
[self.keyboardControls addDelegate:self];
we should add activeField just like below,
我们应该像下面一样添加activeField，
- (void)textFieldDidBeginEditing:(UIView *)textField {
[self.keyboardControls setActiveField:textField];
}
And last step is delegate metods implemantation,
最后一步是委托方法实现，
- (void)keyboardControlsDonePressed:(BSKeyboardControls *)keyboardControls {
[super textFieldShouldReturn:self.keyboardControls.activeField];
}
That's it.
就是这样。
