Question

请帮我解决这个错误!

不知道为什么“let noodle = noodles[indexPath.row]”是错误的

但是“let recipe = recipes[indexPath.row]”是可以的!

以上代码在函数中

Answer 1

假设 segment.selectedSegmentIndex == 0 和 indexPath.row == 2(或任何数字，>= noodles.count) ，并跟踪 tableView(_:cellForRowAtIndexPath:) 的每一行:

//...

let recipe = recipes[indexPath.row]
if segment.selectedSegmentIndex == 0 {
    cell.favorIconImageView.hidden = !recipe.isFavor
    cell.nameLabel.text = recipe.name
    cell.thumbnailImageView.image = UIImage(named: recipe.image)
    // cell.locationLabel.text = recipe.material
    cell.typeLabel.text = recipe.type
    cell.userPhoto.image = UIImage(named: recipe.userPhoto)
    cell.userName.text = recipe.userName
}

let noodle = noodles[indexPath.row] //<-control reaches here with `indexPath.row` == 2
//...

你可能需要这样写:

if segment.selectedSegmentIndex == 0 {
    let recipe = recipes[indexPath.row]
    cell.favorIconImageView.hidden = !recipe.isFavor
    cell.nameLabel.text = recipe.name
    cell.thumbnailImageView.image = UIImage(named: recipe.image)
    // cell.locationLabel.text = recipe.material
    cell.typeLabel.text = recipe.type
    cell.userPhoto.image = UIImage(named: recipe.userPhoto)
    cell.userName.text = recipe.userName
