self.tableView.reloadData()

如何将UITableViewCell走私为! AdCell随机进入UITableView?
我的意思是,我应该在cellForRowAt做什么?我对所有这些索引部分感到有点困惑。
答案 0 :(得分:2)
首先,您需要生成介于0和tableView数据源数组大小
之间的随机数let lower : UInt32 = 0
let upper : UInt32 = array.count
let randomIndex = arc4random_uniform(upper - lower) + lower
然后你需要在randomIndex
中添加数组中的Ad对象array.insert(AdObject, atIndex:randomIndex)
然后只需重新加载tableView并处理cellForRow函数中的不同类型
答案 1 :(得分:1)
一种方法是在数据模型中的所需位置插入某种“广告”对象。
然后更新cellForRowAt
以查看给定索引路径的数据模型中的对象。如果它是“广告”对象,请创建并设置“广告”单元格。否则,就像现在一样创建和设置适当的数据单元。
