我想将我的模型对象数据源更改为firebase.我有一个文件作为UICollection视图的数据源,homeViewController.swift.homeViewController.swift是一个垂直排列的collectionViewCell,每个单元格都有自己的水平排列的collectionViewcell.

这是models.swift文件

import UIKit
import Firebase

class BusinessCategory: NSObject {

var name: String?
var featurebusiness: [SampleBusinesses]?
var type: String?


static func sampleBusinessCategories() -> [BusinessCategory] {
 let FastfoodCategory = BusinessCategory()
    FastfoodCategory.name = "Fast Food"
    var topFastFood = [SampleBusinesses]()

    let FastfoodApp = SampleBusinesses()
    FastfoodApp.name = "Papa Johns"
    FastfoodApp.imageName = "PJ"
    topFastFood.append(FastfoodApp)
    FastfoodCategory.featurebusiness = topFastFood


    let MobilePhoneCategory = BusinessCategory()
    MobilePhoneCategory.name = "Mobile Phones"
    var topMobilePhoneProvider = [SampleBusinesses]()
    //logic
    let MobilePhoneApp = SampleBusinesses()
    MobilePhoneApp.name = "Verizon"
    MobilePhoneApp.imageName = "verizon"
    topMobilePhoneProvider.append(MobilePhoneApp)
    MobilePhoneCategory.featurebusiness = topMobilePhoneProvider

    return …

我有一组UITextfield供用户注册。我的应用程序构建成功，但是每当我尝试在电子邮件文本字段中输入@时，它都会在下面显示消息，并导致无法注册用户，无法单击“注册”按钮。有人知道发生了什么吗？以及如何解决此问题？
