如何在像UITabBarController这样的UIBarbutton上添加徽章？

Question

我想知道如何设置UIButton徽章像UITabBarController徽章？

Answer 1

你只是想一个背景图像添加到按钮

UIImage *image = [UIImage imageNamed:@"YourBadge.png"]; 
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
    button.frame = CGRectMake(200.0, 10.0, 20.0, 20.0); // or whatever dimensions you want 
    [button setBackgroundImage:image forState:UIControlStateNormal]; 

Answer 2

您可以使用MKNumberBadgeView。
