ios objective-c uitableview pstcollectionview
In the app I develop I have a bunch of tiles (PSTCollectionView) on the screen. When user clicks on one cell he gets moved to another controller by calling segue programmatically. To avoid clicking cell several times at a time I add transparent overlay right after cell click that should prevent clicking at any collection tile.Everything seemed to go well until I run it on iPad 1: in some cases device hangs a bit and overlay appears a bit late which leads to the situation that allows user to clic

On iOS, I am adding a CALayer to a UITableViewCell’s layer. This is my first time using CALayer, and it is simply supposed to change the background color of the table cell. My goal is (1) to learn how to use CALayer, and (2) to test using Instruments whether the drawing is faster than my current implementation, which slows down on CGContextFillRect.(Technical Q&A QA1708 was the catalyst for all this.)Current Implementation (works)- (void)drawRect:(CGRect)r {UIColor *myColor = [self someCol

ios apple human-interface
I’m currently developing an app for a client which makes use of a tabbar, but I’m concerned I may be violating the human interface guidelines. My app starts with a home viewcontroller which leads to several other viewcontrollers. One of the viewcontrollers has a tabbar. The very first item on the tab bar is a home button. Clicking the button will send the user back to the home viewcontroller. The home view controller does not have a tabbar. The question of the hour … is this a violation

javascript jquery http backbone.js get
Backbone.js has a neat feature where you are able to sync changes back to your sever using standard HTTP verbs. For example you may have a model object and some code which executes a get:var coolModel = Backbone.Model.extend({url:’mysite/mymodel’}); var myCoolModel = new coolModel(); myCoolModel.fetch({error:processError});Under the case where the server returns a 4XX or 5XX the error function ‘processError’ is run, which is great, you are able to process the error in which ever way suits.As bac

I’m trying to write a script which will download at most N files simultaneously via HTTP. I’ve previously used AnyEvent::Worker::Pool to manage a pool of BLOCKING tasks. I’ve also used AnyEvent::HTTP in combination with AnyEvent->condvar to manage NON-BLOCKING downloads individually. I thought that it should be pretty simple to combine the two approaches so that AnyEvent->condvar makes AnyEvent::HTTP::http_get look BLOCKING from the perspective of AnyEvent::Worker::Pool.However, I’m getting some
