项目中会用到数字键盘的，那如果用户想关闭键盘怎么办?可以通过在键盘上添加额外按钮来实现

#pragma mark - 键盘点击完成之后隐藏
- (void)hidenKeyBord
{
    self.keyBordToolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 38)];
    self.keyBordToolBar.barStyle = UIBarStyleDefault;
    self.codeTextField.inputAccessoryView = self.keyBordToolBar;

    UIBarButtonItem *lastItem = [[UIBarButtonItem alloc]initWithTitle:@" < " style:UIBarButtonItemStyleDone target:self action:@selector(lastItemAction:)];

    UIBarButtonItem *nextItem = [[UIBarButtonItem alloc]initWithTitle:@" > " style:UIBarButtonItemStyleDone target:self action:@selector(nextItemAction:)];

    UIBarButtonItem *nullItem = [[UIBarButtonItem alloc]initWithTitle:@"         " style:UIBarButtonItemStylePlain target:self action:@selector(nextItemAction:)];
    nullItem.enabled = NO;

    UIBarButtonItem *doneItem = [[UIBarButtonItem alloc]initWithTitle:@"完成" style:UIBarButtonItemStyleDone target:self action:@selector(doneItemAction:)];

    self.keyBordToolBar.items = @[lastItem,nextItem,nullItem,nullItem,nullItem,doneItem];
}

- (void)lastItemAction:(UIBarButtonItem *)button
{

}

- (void)nextItemAction:(UIBarButtonItem *)button
{

}

- (void)doneItemAction:(UIBarButtonItem *)button
{
    HidenKeybory;
}

#define HidenKeybory {[[[UIApplication sharedApplication] keyWindow] endEditing:YES];} //让控件取消第一响应者
