：しかし、私はのtableViewに問題がある 更新」の後にセクション0で唯一の0行があり、クラスがこれです
func insertRowMode3(ind:Int) {
let indPath = IndexPath(row: ind, section: 0)
rows = ind + 1
tableView.insertRows(at: [indPath], with: .right)
guard ind < places.count-1 else { return }
DispatchQueue.main.asyncAfter(deadline: .now()+0.20) {
self.insertRowMode3(ind: ind+1)
}
}
は、まさにこの行で：
tableView.insertRows(at: [indPath], with: .right)
私は問題を解決するために、これらの機能を変更する必要が方法がわからない、私はすでに他の質問に周りを見回したが、何か有用なものを見つけることができません。こののUIViewControllerで作業 他のクラスは次のとおりです。
struct QCategoryy {
var name:String
init(name:String) {
self.name = name
}
}
extension QCategoryy: ExpressibleByStringLiteral {
init(stringLiteral value: String) {
self.name = value
}
init(unicodeScalarLiteral value: String) {
self.init(name: value)
}
init(extendedGraphemeClusterLiteral value: String) {
self.init(name: value)
}
}
