问题 While rebuilding my project with the new Xcode 5 released yesterday, I was disappointed to see my storyboard view controller shaken up. After many attempts to fix things, I must conclude I'm stuck with one remaining issue: Navigation View Controller makes the navigation bar overlaps with the content of the view. Doing so, the app is ok on a iOS 7 device (no overlapping), but with a iOS 6.1 device, the navbar overlaps. I ran a sample project from FlatUI to crosscheck the issue, and they have

But none of these are working. My question is,

How can I reproduce website crash on iOS 6.1

阅读更多关于 How can I reproduce website crash on iOS 6.1

问题 I received a bug report that this website crashes when viewed on iOS 6.1, though I guess it's the browser version that comes with iOS 6.1 that's more relevant than the OS itself. I don't own any iOS devices, so I'm not sure how I can reproduce/investigate the issue. Does anyone have a suggestion for how I might reproduce this issue on Windows/Ubunutu? I tried http://www.browserstack.com/ but the latest version they offer is iOS 6.0. In the unlikely event that anyone has an idea why the crash
