Hi, I would like to animate some of the thumbnail images in the Three20 TTThumbsViewController view. The animations will occur randomly, not because of user interaction. TTThumbsViewController subclasses TTTableViewController and uses TTThumbsTableViewCells to layout whatever number of TTThumbViews are needed in that cell. TTThumbViews...

I was hoping it makes a screenshot - however this method only takes the first image of the video - and ONLY IF IT HASN'T BEEN PLAYED! How can I make a thumbnail at an...

I am developing an application that, because I can't use a custom time interval to schedule local notifications, has to create N local notifications to simulate a timed schedule. The application does this once for every X objects (let's call them calendar events for now). So a user can have 100 calendar events, each with 20 local notific...
To better explain this I'll use Doodle Jump as an example. Assuming that the platforms are recycled, when the character jumps up and the new platforms appear (by scrolling down) there is occasionally a propeller hat on one of them. is there a recommended method to manage this new object? Should I instantiate a single one of these power-u...

I'm re-factoring my code and would like to move a whole bunch of UILabels into another class to tidy things up a bit. I'm missing one puzzle piece to be able to do so though (or maybe I'm just tired lol) Anyway here's the simplified code showing my issue. Thanks in advance to anyone who helps :) @interface MyClass : UIView { UILa...
