auto-rotation

问题 I have a Silverlight page that I would like to have below appearance in portrait and landscape mode. Essentially, there are three images arranged in a grid. The big image spans two columns. When the phone rotates, the images rotate, but the overall layout does not. The small images remain close to the back/windows/search button and the large image remains towards the top of the phone. I have tried a number of methods to achieve this effect, but they have all proved unsatisfactory in one way

问题 I'm trying to work with the iOS6 Auto-rotation mess. I've looked at almost every single SO question relating to it, and no matter what I try, I can't get rotation working how I need it. The app is using storyboards, and the layout is as follows: Navigation controller ---> Root view controller ---> Tab view controller ---> View controller ---> Landscape view controller. The view controller auto-rotates when I rotate the simulator, but when segueing back to the previous view (that is set to

问题 How to create an App using the Single View App template where the main window does not rotate but its rootViewController and everything else autorotates? Apple does that on CIFunHouse but because the code is poorly explained in that matter, it is impossible to know how they did it. If you run the app you will see that the camera's preview window does not autorotate because the preview was added to the window but everything else does. Apple uses this technique on their native iPad camera app.

问题 Okay so Im just trying to get it working with rotations first before scaling then once I nail that the rotozoom should be easy. For the life of me I cant seem to get it working. Heres a simple class that I want the object to rotate over time as well a transform in the x direction. The transform is working fine but i just cant get it to rotate. class Puff(pygame.sprite.Sprite): def __init__(self, screen): pygame.sprite.Sprite.__init__(self) self.screen = screen try: self.imagePuff = pygame

问题 I have my entire interface in one Storyboard. How can I make most of the ViewControllers only support a portrait orientation while only a couple supporting all orientations. I can't understand apples new auto rotate system. Also, how can I make this backwards compatable to iOS 5? 回答1: In your Navigation Controller subclass, forward the decision to the top view controller in the stack: -(NSUInteger) supportedInterfaceOrientations { return [self.topViewController supportedInterfaceOrientations]

问题 Need to prevent screen rotation on specific view controller I've tried below- public override bool ShouldAutorotateToInterfaceOrientation(UIInterfaceOrientation toInterfaceOrientation) { return false; } public override bool ShouldAutorotate() { return false; } public override UIInterfaceOrientation PreferredInterfaceOrientationForPresentation() { return UIInterfaceOrientation.Portrait; } public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations() { return

问题 Hi I've a base image and other images that I'd like to rotate with the same angle as the base image. this is my base image. this is an example image that I'd like to rotate. here my full code. #include <stdio.h> #include <iostream> #include "opencv2/core/core.hpp" #include "opencv2/features2d/features2d.hpp" #include "opencv2/highgui/highgui.hpp" #include "opencv2/calib3d/calib3d.hpp" #include "opencv2/nonfree/nonfree.hpp" #include "opencv2/imgproc/imgproc.hpp" #define PI 3.14159265 using

问题 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:updateConstraints method and update constraints according to device orientation. 2. Second approach: Implement the UIViewController:viewWillLayoutSubviews method and update constraints according to device

问题 I'm developing an app and I would like one screen to auto-rotate to landscape. This will be the only rotating screen in the app. I'm trying to find the easiest way of doing this. If I set the supported orientations in the build summary page (i.e. with the toggle buttons) so that it is just portrait. Can I then override this in the code for the screen I want to auto-rotate? Or do I have to do it the other way round? i.e. support all orientations and then disable for all the screens I don't
