1.需求修改UIAlertController中title

[alertControllersetValue:[selfattributedString:titleString]forKey:@"attributedTitle"];

- (NSAttributedString*)attributedString:(NSString*)string

{

    NSMutableAttributedString *attri = [[NSMutableAttributedString alloc] initWithString:string];

    // 添加表情

    NSTextAttachment *attch = [[NSTextAttachment alloc] init];

    // 表情图片

    attch.image = [UIImage imageNamed:@"bt_add_select"];

    // 设置图片大小

    attch.bounds=CGRectMake(0, -6,26,26);

    // 创建带有图片的富文本

    NSAttributedString *attributedString = [NSAttributedString attributedStringWithAttachment:attch];

    [attriinsertAttributedString:attributedStringatIndex:12];

   return  attri;

}
