    ios iphone autolayout device-orientation auto-rotation
    I am developing an application which supports portrait and landscape modes. I am using auto layout to arrange my views. As i have been reading many posts and i have realized that developers commonly use one among the following approaches.1. First approach:Implement the UIViewController::update constraints method and update constraints according to device orientation.2. Second approach:Implement the UIViewController::viewWillLayoutSubviews method and update constraints according to device orienta

    ios6 auto-rotation
    I’m developing for an app with only one view controller visible at this time. If I rotate the device a lot, eventually the private runtime methods that take care of autorotation aren’t getting invoked. I tried setting breakpoints in the code to track down why this is occurring, but so far I haven’t had much luck. Since the application begins ignoring interaction events when the rotation occurs, this means that the interaction events are never handled after rotation (I’m assuming that the same

I am attaching an important part of a crash report.Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x6563616e Crashed Thread: 0Thread 0 name: Dispatch queue: com.apple.main

I am using ECSlidingViewController and in there class, they add a view as such: [self.view addSubview: _topViewController.view];How can i make autorotation work with iOS6, and ECSlidingViewController? I added the f
