[英]In iOS Swift integrate Different array for CollectionView Inside TableView in Swift 4
How to set CollectionView data to Collection tag.collection tag count is not fixed .How to integarte cellForItemAt and numberOfItemsInSection in CollectionView .So I have a collectionView inside of a tableView. 如何将CollectionView数据设置为Collection tag.collection标签计数不固定。如何在CollectionView中集成cellForItemAt和numberOfItemsInSection。所以我在tableView内部有一个collectionView。 I would like to use the values from my array to populate each labels text inside each collectionViewCell.
我想使用数组中的值来填充每个collectionViewCell中的每个标签文本。 If I print the code below in collectionView cellForItemAt.
如果我在collectionView cellForItemAt中打印以下代码。
class testViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout {
@IBOutlet weak var providerCategoryTableView: UITableView!
let collectionReuseIdentifier = "selectServiceProviderCollectioncell" // Collection cell identifier in the storyboard
let tableReuseIdentifier = "selectServiceProviderTableViewCell"
var providerCategoryTableViewDictionary = [NSMutableDictionary]()
var providerCategoryCollectionViewDictionary = [String:Any]()
var providerCategoryDictionary = [[String:Any]]()
var ServiceResponse:[[String:Any]] = {[id:1,provider_name:”Telephone”,providers:[{category_name:”Test1”,id:”1”}, {category_name:”Test2”,id:”2”}]], [id:2,provider_name:”MobileNumber”,providers:[{category_name:”Test3”,id:”1”}, {category_name:”Test2”,id:”2”}, {category_name:”Test4”,id:”4”}, {category_name:”Test5”,id:”5”}]]}
var setIndexTag:Int = 0
var cellForItemIndexTag:Int = 0
var exapandTableViewArray = [Int]()
override func viewDidLoad() {
super.viewDidLoad()
initControls()
}
// Expand function

I want
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
//return collectioncategories.count
if collectionView.tag == 0{
return collectioncategories.count
}else if collectionView.tag == 1{
return collectionSecondcategories.count
}
}
But 0,1....n collectionView.tag not fixed and inside array count also different.Please Its Urgent.Thanks
i have done a similar application where what we did is create one parent array ie 我做了一个类似的应用程序,我们所做的是创建一个父数组,即
var tableViewDataArray = [HomeDataHolder] () // which includes the type , sub category in my case myclass contains category name , category id and product array
after this add each category in to this array for me, added dataArry[banners,toppicks,.....] 在此之后,为我将每个类别添加到此数组中,添加了dataArry [banners,toppicks,.....]
this is how added class object to arraya 这是如何将类对象添加到arraya
if let categoryes = JSON["categories"] as? NSArray{
for index in 0..<categoryes.count{
self.categoryArray.add(categoryes[index])
}
print(self.categoryArray)
self.session.saveCategory(self.categoryArray)
let catObject = HomeDataHolder(type:"CATEGORY").addCategoryes(categoryArray: self.categoryArray)
self.tableViewDataArray.append(catObject)
}
set tableview datasource as this array if you need different type design design different cells 如果您需要不同的类型设计,设计不同的单元格,则将tableview数据源设置为此数组
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let homeData = tableViewDataArray[indexPath.row] as! HomeDataHolder
if homeData.type == "CATEGORY"{
let cell = tableView.dequeueReusableCell(withIdentifier: "category_name_cell", for: indexPath) as! HomeCategoryTableViewCell
cell.selectionStyle = .none
let dataArray = homeData.dataArray
cell.setProducArray(dataArray!)
cell.delegate = self
return cell
}else if .......
in my HomeCategoryTableViewCell class 在我的HomeCategoryTableViewCell类中
func setProducArray(_ data:NSMutableArray){
for index in 0..<data.count{
dataArray.add(data[index])
}
colectionView.reloadData()
}
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return dataArray.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "home_categoryes_cellection_cell", for: indexPath) as! HomeCategoriesCollectionViewCell
if let dataDictionary = dataArray[indexPath.row] as? NSDictionary{
utility.setCornerRadius([cell.containerView], cornerRadies: 19)
cell.categoryNameLabel.text = dataDictionary.getStringValue("name")
print(dataDictionary.getStringValue("name"))
}
return cell
}
and my HomeCategoryTableViewCell contains a collection view cell.setProducArray(dataArray!) will change the datasource of the collectionview 并且我的HomeCategoryTableViewCell包含一个收集视图cell.setProducArray(dataArray!)将更改collectionview的数据源
In your cellForRow of the TableView access the collectionView with viewWithTag and then give it the indexPath.row in the accessiblityHint property and call reload. 在TableView的cellForRow中,使用viewWithTag访问collectionView,然后在accessiblityHint属性中为其指定indexPath.row并调用重新加载。 Then in the your numberOfSections, numberOfItems or cellForItem methods of collectionView you can access the accessiblityHint property and access your array's index to display the data you want.
然后,在collectionView的numberOfSections,numberOfItems或cellForItem方法中,您可以访问accessiblityHint属性并访问数组的索引以显示所需的数据。
