如何在像UITabBarController這樣的UIBarbutton上添加徽章？

Question

我想知道如何設置UIButton徽章像UITabBarController徽章？

Answer 1

你只是想一個背景圖像添加到按鈕

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。
