这是来自另一个堆栈溢出帖子，但似乎工作正常。 Post found here.

UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"Dont care what goes here, since we're about to change below" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];
NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@"Presenting the great... Hulk Hogan!"];
[hogan addAttribute:NSFontAttributeName
          value:[UIFont systemFontOfSize:50.0]
          range:NSMakeRange(24, 11)];
[alertVC setValue:hogan forKey:@"attributedTitle"];



UIAlertAction *button = [UIAlertAction actionWithTitle:@"Label text" 
                                    style:UIAlertActionStyleDefault
                                    handler:^(UIAlertAction *action){
                                                //add code to make something happen once tapped
}];
UIImage *accessoryImage = [UIImage imageNamed:@"someImage"];
[button setValue:accessoryImage forKey:@"image"];

要使用以下内容更改文本的颜色，请将其添加到行设置之前 [alertVC setValue:hogan forKey:@"attributedTitle"];

[hogan addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,35)];
