我需要在collectionview中的水平图像，它位于每个tableview单元格中。我面临的问题是tableview很容易加载，但是collectionview没有在tableview单元格之前加载，因为tableview加载非常快，因此collectionview的数组会被更改。
我用于整个视图的代码是 -
import UIKit
class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout,NSURLConnectionDelegate {
@IBOutlet var tbl_data: UITableView!
var mutableData: NSMutableData!
var response: NSURLResponse!
var connection: NSURLConnection!
var thedata:NSArray!
var ary_OF_collectionView:NSArray!
override func viewDidLoad() {
super.viewDidLoad()
connection_GetPeopleList()
thedata = NSArray()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// Return the number of sections.
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return thedata.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
//println("INdex===\(indexPath.row)")
let cell = tableView.dequeueReusableCellWithIdentifier("dTableViewCell", forIndexPath: indexPath) as! dTableViewCell
var c_snippet:String = ""
if let checkC_snip:AnyObject = thedata.objectAtIndex(indexPath.row).valueForKey("c_snippet")
{
c_snippet = checkC_snip as! String
}
var getImageArray:NSArray = (thedata.objectAtIndex(indexPath.row).valueForKey("images") as? NSArray)!
cell.lbl_like.text = c_snippet
cell.co_v.tag = indexPath.row
if(getImageArray.count > 0)
{
if(getImageArray.count == 1)
{
var getimagePath:String = getImageArray.objectAtIndex(0) as! String
if(!getimagePath.isEmpty)
{
ary_OF_collectionView = getImageArray
}else
{
ary_OF_collectionView = NSArray()
}
}else
{
ary_OF_collectionView = getImageArray
}
}else
{
ary_OF_collectionView = NSArray()
}
cell.co_v.dataSource = self
cell.co_v.delegate = self
cell.co_v.reloadData()
cell.selectionStyle = UITableViewCellSelectionStyle.None
return cell
}
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return ary_OF_collectionView.count
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("CollectionViewCell", forIndexPath: indexPath) as! CollectionViewCell
var getImageUrl:String! = ary_OF_collectionView.objectAtIndex(indexPath.row) as! String
println(getImageUrl)
// This is image loader From == https://github.com/natelyman/SwiftImageLoader
ImageLoader.sharedLoader.imageForUrl(getImageUrl, completionHandler:{(image: UIImage?, url: String) in
cell.img.image = image
})
//cell.img.image = UIImage(named: ) as UIImage!
return cell
}
func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath)
{
println("INinininin===\(indexPath.row)")
// var cell:dTableViewCell = cell as! dTableViewCell
// [cell setCollectionViewDataSourceDelegate:self index:indexPath.row];
}
func scrollViewDidScroll(scrollView: UIScrollView) {
println(scrollView)
// println("INinininin===\(scrollView.tag)")
}
func connection_GetPeopleList()
{
let urlPath: String = "http://carbonchase.com/v1.1/get_jives.php?user_id=3221128362&at=0&newsfeeds&count=10"
println("get_People List == \(urlPath)")
var escapedAddress = urlPath.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())
var url: NSURL = NSURL(string: escapedAddress!)!
var request1: NSURLRequest = NSURLRequest(URL: url)
self.connection = NSURLConnection(request: request1, delegate: self, startImmediately: true);
connection.start()
}
func connection(connection: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
self.response = response
self.mutableData = NSMutableData()
}
func connection(connection: NSURLConnection!, didReceiveData data: NSData!) {
self.mutableData.appendData(data)
}
func connectionDidFinishLoading(connection: NSURLConnection!)
{
if let jsonResult: NSArray = NSJSONSerialization.JSONObjectWithData(self.mutableData, options: nil, error:nil) as? NSArray {
thedata = jsonResult
self.tbl_data.reloadData();
self.tbl_data.delegate=self;
self.tbl_data.dataSource=self;
}
}
func connection(connection: NSURLConnection, didFailWithError error: NSError) {
println("\(error)")
}
}// END
EDITED
CollectionView无效
