If anyone has some clue like how to actually implement it or some code, that would be ...

I load a UIImageView with an image depending on user interaction. When the parent view is initially displayed, no image has been selected and the imageview is black. If the user leaves that view and comes back, the image is still there. I've tried myImageView.image = nil; upon leaving the view but the image remains. How can I remo...
To extend on the subject, ...without crashing? I load about 15 full size images from the photo library in UIImageViews and get out of memory warnings and eventually an app crash. These images range from around 250KB to 400KB. The UIImageViews are set to aspect fit. The photo library seems to load smaller file size versions of images,...
Hey guys, (relatively, I believe) simple question here, I have a UITableViewController with its UITableView, with its determined number of cells.

Hi, all! I'm developing a game in which I'm reducing the frame size of an imageView.

So, I want to introduce a delay after every instruction so that I can see the effect of i...

My iPhone app shows the user some massive images, I've successfully tiled them and used a UIScrollView to allow them to pan around and look at parts of it in detail. Now I want to draw points above that background image and have them move around when the user pans/zooms, essentially like placing a pin on a notice board. I don't want to m...
