推荐答案

你可以使用更新文本颜色

You can update text color using

       UIAlertAction *myGoalAction = [UIAlertAction
                                    actionWithTitle:NSLocalizedString(@"My Title", @"My Title")
                                    style:UIAlertActionStyleDefault
                                    handler:^(UIAlertAction *action)
                                    {

                                    }];
       [myGoalAction setValue:[UIColor greenColor] forKey:@"titleTextColor"];

没有有效的方法来更新字体大小.我建议你使用标准字体大小.

There is no efficient way to update font size.I will suggest you to use standard font size.

UIAlertAction 标题标签是私有变量，不能直接访问.标签位于 3 级私有视图层次结构中.使用更大的字体显示注销操作对应用程序有意义.

UIAlertAction title label is private variable and not accessible directly. Label comes inside 3 level private view hierarchy. Showing logout action with bigger font make sense for app.

有很多开源解决方案可用.我会推荐尝试this

There are many open source solution available.I will recommend to try this
