MKaro的解决方案有效！我将附加Swift 3版本以便更快地复制粘贴。

斯威夫特3：

let keyboardToolbar = UIToolbar()
keyboardToolbar.sizeToFit()
keyboardToolbar.isTranslucent = false
keyboardToolbar.barTintColor = UIColor.white

let addButton = UIBarButtonItem(
    barButtonSystemItem: .done, 
    target: self, 
    action: #selector(someFunction)
)
addButton.tintColor = UIColor.black
keyboardToolbar.items = [addButton]
textView.inputAccessoryView = keyboardToolbar

Answer 2

简单，您只需要使用UIToolBar和UIBarButtonItem。

这是一个简单的例子，它使＆＃34;特殊键盘＆＃34;对于特定的TextField：

此代码创建工具栏：

UIToolbar *keyboardToolbar = [[UIToolbar alloc] init];
[keyboardToolbar sizeToFit];
keyboardToolbar.translucent=NO; //if you want it.
keyboardToolbar.barTintColor = Some Color; //the color of the toolbar

此代码创建您想要的按钮

UIBarButtonItem *doneBarButton = [[UIBarButtonItem alloc]
                                  initWithBarButtonSystemItem:UIBarButtonSystemItemDone
                                  target:self.view action:@selector(set your own function here:)];
[doneBarButton setImage:CHOOSE YOUR IMAGE];
keyboardToolbar.items = @[doneBarButton];//you can add couple of buttons if you want to.
yourtextfield.inputAccessoryView = keyboardToolbar;
