Hello, I'm trying to develop an app with Edge Animate and Buzztouch (still trying). I'm not sure if I'll be able to do it, and I have two main doubts: 1- How can I program my app for both iPhone 4 and 5 (even iPhone3)?. I've downloaded from Xcode the iOS 5.1 and iOS 4.3 simulator (iOS 6.0 default). When I create my project from Buzztouch, it only works on iOS 6 and iOS 5.1, but it doesn't work on iOS 4.3. 2- What is debugging? Do you need to learn coding to do it? There is some Xcode option for this? Thanks!

1) buzztouch automatically optimizes your app for iPhone 5. If you want your app to work on early iOS version, go into Xcode, and set your deployment target (iOS). 2) Xcode alerts you where the issue is in your app.

What is deployment target? TK

Go into xcode, look all the way to the left where the grey sidebar is. Move your eyes to the write just a little so you see the white sidebar. You should see (in the white bar) PROJECT and TARGETS. Click on the one button right under TARGETS. Move your eyes to the middle of the screen. See those blue, thin bars? Look at the first one on the top. Right underneath that first blue bar, you should see Bundle Identifier. Look down a few more (still under that first bar), until you see deployment target. Deployment target is the setting for your app: you pick the iOS. So if you pick 3.0, people who have iOS 3.0 or above can download your app. If you pick 4.3, people will then be able to download your app.

Sorry, I pressed the enter button accidentally and the post duplicated. I've read your detailed post. it's very appreciated. However, I don't find the "deployment target" there. Please, take a look to this screen capture: http://www.marballesteros.com/uploads/Deployment.tiff

Click on Summary and you will see deployment target.

Right! It is configured as 3.0. Does it mean that theoretically, my app could run in iPhone 2, 3, 4 and 5? For the moment, my app doesn't run in the simulator with iOS 4.3 version...

iPhone 2 doesn't exist. It goes 1, 3g, 3gs, 4, 4s, 5. Your app should run in the simulator with 4.3. If it configured as 4.3, you support iOS 4.3 and up. If it is configured as 3.0, you support iOS 3.0 and up. You cannot support anything lower than iOS 3.0. I am not sure, but in a matter of time you will not be able to support 3.0 either.

Thanks, I'll see what the problem is...

@munny1 makes an important point here...the deployment target is for iOS level, and not hardware levels. So, if you have a particular hardware device you want to support (say first gen iTouch or something), then you need to make sure you understand what the older iOS version is that it support. All my apps are targeted to iOS 3, and I believe that hits a huge swath of what's running out there. Mark

Thanks Mark, that's a good point, indeed. Mar

Same as Mark, I support 3.0 instead of 4.3. Almost everyone I know is on such a low iOS that they would never be able to get apps if they were not set to 3.0.
