问题 I was wrestling with UIScrollview and it knocked me out. I tried to take reference from following two post on stackOverFlow scrollview xcode4.5 autolayout, Xcode 4.5 UIScrollView, Embed ImageView in ScrollView with Auto Layout on iOS 6, I tried viewDidLayoutSubviews, as told in UIScrollView setContentSize breaks view with Auto Layout that is causing my app to crash. And I tried ViewDidLoad, viewDidAppear and viewWillAppear but nothing worked. I tried google and found couple more related post

Since upto my knowledge, it may show the MetaData error if I don't upload the screenshots for iPhone4/4S. So, simply I would like to have my app running on

问题 I have a web page being displayed in a UIWebView that uses jquery scrollTop (using 1.6.4 version of jquery) to scroll the window to a speicified position after the page is loaded. This was working fine with xcode older than 4.5. After I built it using xcode 4.5 the page momentarily shows the background of the UIWebView before scrolling. This happens only in ios6. Has anyone encountered any similar issue with xcode 4.5 and ios6? Is there any new API for UIWebview that I can use to stop this

问题 I was using that method for pushing another UIViewController in if condition : initViewController *MW = [initViewController alloc]; MW = [self.storyboard instantiateViewControllerWithIdentifier:@"init"]; [self.navigationController pushViewController:MW animated:YES]; Now i've changed my architecture and i just removed my Navigation controller. That's why , these steps will not help me any longer due to no NavigationController exist. Now how can i push another ViewController without pressing
