i have get the value from mySQL Database and all its coming and one of them is URL link for image that and its save in the same web host
func loadData() {
let url = NSURL(string: "http://www.q8-9ndo5aan.com/kuwaitExpoApps/script/getExpo.php")
let request = NSMutableURLRequest(URL: url!)
// modify the request as necessary, if necessary
NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: { (data:NSData?, response:NSURLResponse?, error:NSError?) -> Void in
dispatch_async(dispatch_get_main_queue(), {
if error != nil {
// Display an alert message
print(error)
return
}
do {
let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? [[String:AnyObject]]
if (json != nil) {
for item in json! {
self.expoImage.append((item["expoImage"] as? String)!)
self.myCollectionView.reloadData()
}
// Display an alert message
} else {
// Display an alert message
let userMessage = "Could not fetch Value"
print(userMessage)
}
} catch {
print(error)
}
})
}).resume()
}
and when i print in console of Xcode the link displayed well , but my problem is did not displayed the image in the UICollectionView
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let myCell: myCollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("myCell", forIndexPath: indexPath) as! myCollectionViewCell
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
let imageString = self.expoImage[indexPath.row]
let imageUrl = NSURL(string: imageString)
let imageData = NSData(contentsOfURL: imageUrl!)
dispatch_async(dispatch_get_main_queue(), {
if(imageData != nil) {
myCell.expoImage.image = UIImage(data: imageData!)
myCell.expoImageBack.image = UIImage(data: imageData!)
}
});
});
return myCell
}
any one have ideas for that
