По сути, из корня навигационного контроллера, табличного представления, я строю строку URL, содержащую информацию, которую я хочу отобразить в новом tableView.в новом табличном представлении я использую URL для запроса NSURL.Мой код не дает мне ошибки, но вылетает, сразу после ячеек NSLog: made.помочь, прежде чем я убью себя.извините, все должны быть вместе, но копирование кода вставки явно не работает.
