ipad-2

问题 I want to display the stream of the front and the back facing camera of an iPad2 in two UIViews next to each other. To stream the image of one device I use the following code AVCaptureDeviceInput *captureInputFront = [AVCaptureDeviceInput deviceInputWithDevice:[AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo] error:nil]; AVCaptureSession *session = [[AVCaptureSession alloc] init]; session addInput:captureInputFront]; session setSessionPreset:AVCaptureSessionPresetMedium]; session

问题 I want to check if iOS device I am using has support for Facetime call. I don't want to check the iOS version on the device, rather if the device has the hardware support to initiate a Facetime call. For example: I have an iPad 1 with iOS version 4.0 and above, but if I don't have a camera (or a front camera), the Facetime call should not initiate. How can I do this? 回答1: Try using canOpenUrl method with FaceTime scheme, as follows: [[UIApplication sharedApplication] canOpenURL: [NSURL

问题 Is there anyway to detect between the iPad and iPad2 via Jquery / Javascript?

问题 I want to develop an App that requires wired communication between Web cam type video camera and iPad2. Basically I will directly connect Web cam and iPad2 using cable and when I start web cam, whatever images(picture/video) captured by web cam should be displayed on iPad2. Based on my research on this I found that iPad2 cable is only made for iPod Program so the connector is not a traditional USB port I can't do direct communication between web cam and iPad2. Am I missing anything? We are

问题 I made an app with a feature to capture and save video. I have used AVFoundation for that and Apple's AVCam has been my guide. I hope I can make it clear: Everything works fine until I release the videoViewController that handles the AVCamCaptureManager for the first time (In AVCam that would be AVCamViewController). After that when I create it again, the video freezes right after camera switch. Even re-run will not help, nor will clean, or device reset. (Sometimes one of the things help, but
