我想使单元格中的某些单词不可见或可见。这是我的下面的代码。

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
cell = tableView.dequeueReusableCell(withIdentifier: "cell") as? TableViewCell
var dic = ar[indexPath.row]
cell!.cell0.text = dic["date0"]
具有“ Helloworld”
以后我需要“ Helloworld”，所以我不能仅从cell!.cell0.text中获取“ world”。
我想在表格视图中仅显示“世界”。
有人可以帮助我吗？ 谢谢！
答案 0 :(得分：-1)
您要查找的是子字符串。
let string = "Helloworld"
let beginningText = String(string.suffix(5)) //world
let endText = String(string.prefix(5)) //Hello
let start = string.index(string.startIndex, offsetBy: 1)
let end = string.index(string.endIndex, offsetBy: -3)
let range = start..<end
let middleText = String(string[range]) //ellowo
有关更多信息，请参考另一个问题的答案：Link
答案 1 :(得分：-1)
在单元格类中，您可以这样：
var str = "Helloworld"// for example
var splitString = str.components(separatedBy: "Hello")
self.label.text = splitString
答案 2 :(得分：-3)
签出已隐藏
使用 isHiddem ，您可以选择是否显示文本作为布尔值
