小气泡功能在中的两种实现方案-阿里云开发者社区

看到别人的app有小气泡感觉很好玩，并且他们的宽高都不超过所在单元格的宽高，其实它也没有什么神奇我们可以用两种方案来实现：控件方案和多视图方案。

第一种方案：控件法。已经实现一个页面有一个气泡的情况。可以抽象出一个类，调用它就可以了，理论上也可以实现多气泡的情况。可以通过申请一个小气泡对象，制定小黑条的宽度，预置显示的内容。通过self.buttonH5.buttonPressed = ^(NSInteger tag)来实现点击小黑框内容的页面跳转。

实际页面：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = nil;
    if (indexPath.section == 1) {
    .
    .
    .
             if (![[self.dictData valueForKey:@"consigneeTel"]  isEqualToString:@""])
//        if (2 == [[self.dictData valueForKey:@"quickType"] longValue])
        {
            //普通发单

//            if (1 == [[self.dictData valueForKey:@"quickType"] longValue])
            {
                UIButton* buttonDetail =[UIButton buttonWithType:UIButtonTypeCustom];
                buttonDetail.frame = CGRectMake(0, 0, 40 , 40);
                UIImage *image1 = [UIImage imageNamed:@"prompt_fare_card"];
                [buttonDetail setImage:image1 forState:UIControlStateNormal];
                [buttonDetail.imageView sizeToFit];
                [buttonDetail addTarget:self action:@selector(buttonDetail) forControlEvents:UIControlEventTouchUpInside];
                [buttonDetail setCenter:CGPointMake(WINDOW_WIDTH-18, labelSuceessed.center.y)];
                [contentCell addSubview:buttonDetail];

第二种方案：多视图方案，对不同单元格斗加入2个uiview(一个显示长内容信息，另一个显示短内容信息)，通过数据源控制uiview的显示和隐藏。又称多气泡法，有无气泡不确定。具体是一张表有很多记录，每个单元格都有可能有小气泡，也可能没有（本质是有只是把它隐藏了），点击小气泡会显示小黑条，每个小黑条显示的内容不长度不同，点击小黑条进入不同的h5页面,点击其它非气泡按钮，滚动表格，选择表格的行事件小黑条隐藏，点击气泡若以前有小黑条显示就隐藏小黑条并显示本气泡的小黑条，若没有只显示本气泡的小黑条。这种气泡我采用的是对每个cell建立一个带xib对象，增加相关控件。有气泡按钮过小增加透明按钮的处理，分解小黑条的按钮图片文字3个button。在表格加载函数中处理小气泡和小黑条的显示和指针记录。点击气泡时我记录了当前数据的行数，和显示UIVIEW。我定义两个UIVIEW为显示不同长度的小黑条。

实际页面：多个小气泡。

实际页面：多个小气泡之间的互斥，只能显示一个小黑条，并且滑动表格，小黑条消失，点击小黑条跳到html5页面。

实际页面：多个小气泡之间的互斥，只能显示一个小黑条，并且滑动表格，小黑条消失，点击小黑条由于没有计费策略所以跳到html5页面又跳回来。
