Question

下面是我用来格式化数字并将其重新分配回文本字段的代码。在删除文本时，我遇到了一些问题，完整的文本被删除而不是逐个字符，而且我无法重新输入文本。请指导我解决这个问题。

    (function () {
  'use strict';

  angular
    .module('orders')
    .config(routeConfig);

  routeConfig.$inject = ['$stateProvider'];

  function routeConfig($stateProvider) {
    $stateProvider
      .state('orders', {
        abstract: true,
        url: '/orders',
        template: '<ui-view/>'
      })
      .state('orders.list', {
        url: '',
        templateUrl: 'modules/orders/client/views/list-orders.client.view.html',
        controller: 'OrdersListController',
        controllerAs: 'vm',
        resolve: {
          orderResolve: getOrders
        },
        data: {
          pageTitle: 'Orders List'
        }
      })
      .state('orders.create', {
        url: '/create',
        templateUrl: 'modules/orders/client/views/form-order.client.view.html',
        controller: 'OrdersController',
        controllerAs: 'vm',
        resolve: {
          orderResolve: newOrder
        },
        data: {
          pageTitle: 'Orders Create'
        }
      })
      .state('orders.edit', {
        url: '/:orderId/edit',
        templateUrl: 'modules/orders/client/views/form-order.client.view.html',
        controller: 'OrdersController',
        controllerAs: 'vm',
        resolve: {
          orderResolve: getOrder
        },
        data: {
          pageTitle: 'Edit Order {{ orderResolve.name }}'
        }
      })
      .state('orders.view', {
        url: '/:orderId',
        templateUrl: 'modules/orders/client/views/view-order.client.view.html',
        controller: 'OrdersController',
        controllerAs: 'vm',
        resolve: {
          orderResolve: getOrder
        },
        data: {
          pageTitle: 'Order Details {{ orderResolve.name }}'
        }
      });
  }

  getOrder.$inject = ['$stateParams', 'OrdersService'];
  function getOrder($stateParams, OrdersService) {
    return OrdersService.get({orderId: $stateParams.orderId}).$promise;
  }

  newOrder.$inject = ['OrdersService'];
  function newOrder(OrdersService) {
    return new OrdersService();
  }
}());

我运行了你的代码并没有遇到这些问题。如果您使用的是XIB或Storyboard，请仔细检查“编辑开始时清除”未选中“

另外，我需要设置变量才能使其工作：

var maxCharactersLimit = 10

和textField（_ textField：UITextField，shouldChangeCharactersIn范围：NSRange，replacementString string：String）

let finalTextCount = textField.text?.characters.count != nil ? textField.text!.characters.count : 0

numberformatter（样式货币）删除不起作用
