ios - Xcode I Tableview viewItemWithTag 无法从 UITableViewCell 转换为 UIImageView

Question

那是 cellForRowAtIndexPath 函数。我想设置单元格的 UIImageView child 的照片，但我无法为此创建导出。它崩溃说:

Could not cast value of type 'UITableViewCell' (0x22d3e0f40) to 'UIImageView' (0x22d3e5810)

let cell = tableView.dequeueReusableCell(withIdentifier: "PostCell", for: indexPath)    
let profileImageView = cell.viewWithTag(0) as! UIImageView 
return cell

Answer 1

默认情况下，每个 View 都有 0 标签，因此您需要从 Storyboard中将标签 1 提供给您的 UIImageView ，然后您需要替换

let profileImageView = cell.viewWithTag(0) as! UIImageView

与

 let profileImageView = cell.viewWithTag(1) as! UIImageView
