autorotate

问题 When running a simple proof-of-concept iPhone app on my phone (iOS 13.1.2), it doesn't rotate upside down. It will rotate to either of the landscape orientations just fine, but not upside down. One strange thing is that there's also a UITextEffects window whose view controllers get supportedInterfaceOrientations called on them (and they return .allButUpsideDown , which matches with the observed behavior). The project is here, but I'll show all of the code inline. AppDelegate.swift: import

问题 I have a root view controller that will have up to 10 or so subviews. I am implementing autorotation/autosize accross the entire app. My problem is this: - When I allocate all the view controllers and add each as a subview to the root controller during startup, everything works as it should. The only problem is that each view controller needs time to initialize. This causes my application to load very slowly. Instead I am trying to allocate the view controllers as they are required. Now I

问题 I am experiencing an odd problem with legacy code running in iOS8. The code was originally written pre-iOS6, pre-storyboards (using nibs) and functioned without issue on iOS7. However, strange behavior began to occur when running on iOS8. The app is set to run only in landscape (left or right). Therefore it should support autoRotation from landscape-left to landscape-right. The first problem was that the initial view controller was loaded in portrait and one side was cut off. This issue was

问题 My app is entirely designed for IOS6. I use an xib for the iPhone and another one for the iPad. My AppDelegate sets up a TabBarController, though there is no class for the TabBarController itself. The TabBarController has two tab items, 1 a NavigationController, and 1 a View Controller, each of which has its own class. I would like the iPad to be able to run in just Portrait mode, upside down, and normal. On the summary tab of Target in Xcode, I have supported interface orientations set to

问题 I've spend the past three days trying to figure out the iOS-6 autorotation mess, and have not arrived at a solution. It's relatively straight-forward to have an app where all views rotate, or where rotation is completely disabled. And (conveniently for our needs) if you use a MPMoviePlayerViewController it will autorotate even if the app has autorotation disabled. But having conditional autorotation, where some views are allowed to rotate and others are not, is elusive. I can achieve

问题 I've built a horizontal accordion that animates on click. I want to add auto-rotating functionality to it so the slides will rotate by themselves every three seconds but i cannot figure this part out... Here is the code for the Horizontal Accordion: <div id="slideshow"> <ol id="slides"> <li class="slide open active" id="slide-1"> <a href="recipe_detail.aspx?did=1014"><img src="media/images/recipes/featured-tuna-chop-chop-salad.jpg" alt="" /></a> <a class="slidebutton" href="javascript:void(0)

问题 I want to force my view to go for landscape, just when I call a method. When my method runs I call: [self shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)UIInterfaceOrientationLandscapeRight]; Method to autorotate - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation { return UIInterfaceOrientationIsLandscape(toInterfaceOrientation); } The problem is that the view don't force the rotation. Is possible to test it on the simulator, or just

问题 I have a tab bar application in which i have 3 diffrent views each with there own view controller. In the tab bar code i have this, to handle rotation. #import "RotatingTabBarController.h" @implementation RotatingTabBarController // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return [self.selectedViewController shouldAutorotateToInterfaceOrientation
