在 code 下使用 KVC 适用于 ios8。

   UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"Title label" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];
    NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@"Testing text"];
    [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"];
