Because I can never find this when I need it, here is the location where XCode stores screenshots: ~/Library/Application Support/Developer/Shared/Xcode/Screenshots To take screenshots for the iPhone, iPad, or iPod Touch, go to Window –> Organizer and click on the device within Organizer. You’ll see a tab titled “screenshots.” You can also drag and drop the [...]

I don’t think you can debug an ad-hoc build of an iPhone app using XCode or Instruments. I thought it was possible, but after much failure I’ve decided I was fooling myself. But you can do the same build with your developer certificate and it will work fine, even with release settings of course. Wouldn’t [...]

Just a note to those who are tempted to troubleshoot performance while in debug mode. All those NSLog statements (if you’re like me, you have hundreds of them for debugging/testing as you go) can have a definite, visible impact on performance. Try turning debug mode off and see if you still need to tweak anything. [...]

This is a post about NSBundle’s pathForResource. My code pseudo-randomly selects between 3 “banners,” which are HTML files inside my project. There are some battles worth fighting, I have found, and some not. Maybe on a rainy day I will figure out why this works: int whichBanner = (arc4random() %3) + 1; // random 1 [...]
