UIWebview crashing on IOS 7 but not on IOS 6
I'm using Xcode 5 to make my app. When I run it on the simulator using IOS 6.1 everything works perfectly, but when I run the app on IOS 7 it crashes! Here is the crash log I'm getting from the webview:

I figured out the problem, @Jake Lin's suggestion was right it was the link. I was trying to connect to twitter and I was using the URL: http://mobile.twitter.com/account and I tried changing it to: https://mobile.twitter.com/account where I added the "s" in the http. Very strange problem but that seemed to fix it.
