我正在为课程构建一个 iOS 应用程序,并且正在按照一些说明进行操作。“编辑”按钮连接到toggleEditingMode,但是当我更改文本时,由于某种原因,字体大小被重置为 17,即使在故事板编辑器中它是 30。
我尝试过更改字体大小,如果我在执行 setTitle 后打印当前字体大小,它仍然显示 30,所以看起来它一定发生在 setTitle 之外,但只有在我使用 setTitle 时才会触发。帮助!
class ItemsViewController: UITableViewController {
var choreStore: ChoreStore!
var roommateStore: RoommateStore!
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return choreStore.allChores.count
}
override func tableView(_ tableView: UITableView,
cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Create an instance of UITableViewCell with default appearance
let cell = tableView.dequeueReusableCell(withIdentifier: "chore", for: indexPath) as! ChoreCell
// Set the text on the cell with the description of the item
// that is at the nth index of items, where n = row this cell
// will appear in on the table view
let chore = choreStore.allChores[indexPath.row]
cell.title?.text = chore.title
cell.turn?.text = "\(chore.whoseTurn())'s Turn"
cell.completed?.text = chore.completedString()
cell.completed?.textColor = chore.isOverdue ? .red : .black
return cell
}
@IBAction func addNewItem(_ sender: UIButton) {
}
@IBAction func toggleEditingMode(_ sender: UIButton) {
setEditing(!isEditing, animated: true)
sender.setTitle(isEditing ? "Done" : "Edit", for: .normal)
}
}
