This post is for people who are trying to get their iPhone or iPad apps to connect to their hardware synthesizers or controllers via Wi-Fi. For instance, if you're using one of my synth patch editing apps, or trying to play a synth app on your iPad with a MIDI keyboard, then this is what you want.
Today I was finishing up work on version 1.4 of Pouch, and one of the things I wanted to add was some basic analytics tracking, to see how often the app was getting used (basically, just a count of how many times people launch the app). Since I'm already a KISSmetrics user, I figured that would be the best way to go.

A useful article by the creator of Tweetie on how to get better scrolling performance for UITableViews in your iOS apps. In short: just use one custom view within each UITableViewCell (instead of composing your cells of multiple subviews).
Recently I added Facebook image sharing to Glory Math 1, and it was my first experience with the Facebook iOS SDK. I used the newer Sign Sign-On feature, which briefly takes the user to the Facebook app to ask them whether your app can access their Facebook profile. The docs are good, and the whole process was pretty straightforward, but one aspect of the authentication process really annoys me: Every time my app launches again, the user must go through the authentication process with Facebook. The first time the user authenticates, it'll ask for access, but every time after that, it just tells the user that they already approved the application for access, and they just have to tap "Okay". This process seems pointless to me. So, I tried to find a way around it.
