[英]Type 'ViewController' does not conform to protocol 'UICollectionViewDataSource'
[英]ios 8.1: Type 'ViewController' does not conform to protocol 'UICollectionViewDataSource'
编译 swift 应用程序(iOS 8.1)时出现以下错误
类型“ViewController”不符合协议“UICollectionViewDataSource”
在“class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate”行
我刚刚在这里查看了几篇帖子,但没有人帮我解决这个问题。
这是 ViewController.swift 文件的代码:
import UIKit
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
var tableDescription: [String] = []
var tableNumbers: [String] = []
override func viewDidLoad() {
super.viewDidLoad()
self.populateView()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func collectionView(collectionView: UICollectionView, numberOfItemInSection section: Int) -> Int{
return tableDescription.count
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell{
let cell: CollViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("Cell", forIndexPath: indexPath) as CollViewCell
cell.lblDescription.text = tableDescription[indexPath.row]
cell.lblNumber.text = tableNumbers[indexPath.row]
return cell
}
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
println("Cell \(indexPath.row) selected")
}
}
检查代码中的拼写错误,例如 - 使用“numberOfItemsInSection”而不是 numberOfItemInSection。
