管理員可以添加圖像/文本,內容顯示,但圖像添加後不會執行。我需要添加文字才能顯示圖像。例如,我可以添加大量圖像,它們在表格中,但直到管理員添加一些文本後才能查看它們。Tableviewcell不顯示圖像| Swift
的事情是,我轉換圖片用base64,添加到陣列,和我的cellForRowAtIndexPath其解碼並添加到單元格。
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
var data = NSData()
data = UIImagePNGRepresentation(image)!
let base64String = data.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength)
let newImage = "imageBase64" + base64String
content.append(newImage)
self.dismissViewControllerAnimated(true, completion: nil)
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
if content[indexPath.row].rangeOfString("imageBase64") == nil {
let cell = self.articleTableView.dequeueReusableCellWithIdentifier("Text Cell", forIndexPath: indexPath) as! TextTableViewCell
cell.textArticle.text = content[indexPath.row] as String
return cell
}
else{
let cell = self.articleTableView.dequeueReusableCellWithIdentifier("Image Cell", forIndexPath: indexPath) as! ImageTableViewCell
let imageString = content[indexPath.row].stringByReplacingOccurrencesOfString("imageBase64", withString: "")
let decodedData = NSData(base64EncodedString: imageString, options: NSDataBase64DecodingOptions.IgnoreUnknownCharacters)
let decodedImage = UIImage(data: decodedData!)
cell.backgroundColor = UIColor.clearColor()
cell.imageArticle.image = decodedImage
return cell
}
如何讓圖像立即顯示?
哦哈哈,我的錯。謝謝! –
