IOS Webview slow on iPad 1 and iPhone 3gs

Question

I'm currently developing an iPhone app with a webview. The app works on every device higher than an iPad 1 or iPhone 3gs but on those two devices it running slow after about 5 min.

It just a simple app with a webview, and when I try it on the iPad 2 is runs smooth. The website i'm loading has some javascript but it works on the safari browser of the iPad 1 and the iPhone 3gs.

Does anybody know what's going wrong?

Thx!

Answer 1

I don't use ARC but found the problem.

In the app I use the Reachability class from apple to check if the device has an internet connection. My loading function was looping and the apps keeps testing the connection.

After I changed the loading function to check the connection only once the problems is gone!
