Title Body

I have a UITableView with a list of items. Selecting an item pushes a viewController that then proceeds to do the following. from method viewDidLoad I fire off a URLRequest for data that is required by on of my subviews - a UIView subclass with drawRect overridden. When the data arrives from the cloud I start building my view hierarchy. the subclass in question gets passed the data and it's drawRect method now has everything it needs to render. But. Because I don't call drawRect explicitly - Cocoa-Touch handles that - I have no way of informing Cocoa-Touch that I really, really want this UIView subclass to render. When? Now would be good! I've tried [myView setNeedsDisplay]. This kinda works sometimes. Very spotty. I've be wrestling with this for hours and hours. Could someone who please provide me with a rock solid, guaranteed approach to forcing a UIView re-render. Here is the snippet of code that feeds data to the view: // Create the subview self.chromosomeBlockView = [[[ChromosomeBlockView alloc] initWithFrame:frame] autorelease]; // Set some properties self.chromosomeBlockView.sequenceString = self.sequenceString; self.chromosomeBlockView.nucleotideBases = self.nucleotideLettersDictionary; // Insert the view in the view hierarchy [self.containerView addSubview:self.chromosomeBlockView]; [self.containerView bringSubviewToFront:self.chromosomeBlockView]; // A vain attempt to convince Cocoa-Touch that this view is worthy of being displayed ;-) [self.chromosomeBlockView setNeedsDisplay]; Cheers, Doug
