ios - Retrieve images from parse before UITableVIew has loaded? -
In everything except look after a tense delay images in cell works fine. The table is too ugly to show a blank image I think that some time around 0.3 seconds after View Loading ... the
I load only images since parsing show The tableView can be done (why not by the cache?). Or maybe I can hold the launch screen for a long time ..? Table initial view weave app
queryForTable
- (PFQuery *) queryForTable {PFQuery * query = [PFQuery queryWithClassName: self.parseClassName ]; // If any object is not loaded in memory, then we should first check the // cache to fill the table and then later against a query / network. If ([self.objects count] == 0) {query.cachePolicy = kPFCachePolicyCacheThenNetwork; } [Query order BIACC: @ "name"]; Return query; }
cellForRowAtIndexPath
- (UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath object : (PFObject *) objects {static NSString * simpleTableIdentifier = @ "cell"; UITableViewCell * cell = [TablesView decomputer reusableWelcome Identifier: SimpleTable Identifier]; If (cell == null) {cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier: simpleTableIdentifier]; } // loading iconPFFile * thumbnail = [Object objectForrequiry: Self imzeci]; PFImageView * thumbnailImageView = (PFImageView *) [Cell ViewViewGuet: 100]; ThumbnailImageView.file = Thumbnail; ThumbnailImageView.image = [UIImage image named: @ "placeholder.jpg"]; [Thumbnail image load these backgrounds: ^ (UIImage * image, NSError * error) {if (error!) {}}]; // Cell Selktekst Labelktekst = [object Objektforeki: Swektekstki]; Return cell; }
thanks in advance :)
there is a loss of a while This is a standard process to load images after and there are many world-class apps (try scrolling in anytime from Facebook or Twitter app). The work around it would be quite messy in logical and programmatic terms.
