最后我找到了在UIBarbutton项目上添加徽章的方法。我搜索很多，但没有找到正确的答案。所以我创建了UIButton并将其添加为右栏按钮项目的自定义视图。添加 MKNumberBadgeView 以显示徽章编号。下面我为你添加了我的代码。

// Initialize NKNumberBadgeView...
MKNumberBadgeView *number = [[MKNumberBadgeView alloc] initWithFrame:CGRectMake(60, 00, 30,20)];

UIButton *btn = [UIButton  buttonWithType:UIButtonTypeCustom];
    btn.frame = CGRectMake(0, 0, 70, 30);

    [btn setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.1 alpha:0.2]];
    btn.font = [UIFont systemFontOfSize:13];
    //[btn setFont:[UIFont systemFontOfSize:13]];
    [btn addSubview:number]; //Add NKNumberBadgeView as a subview on UIButton
