Slide over and split view in iPad simulator

拜拜、爱过 提交于 2020-12-28 09:59:46
问题 iOS 9 introduced slide over and split view for iPad. How do I simulate these features on an iPad simulator? I have tried swiping from right on iPad Air 2 simulator with no luck. 回答1: To simulate slide over: drag from the right edge (starting from a point very close to the edge). To simulate split view: tap on the small white bar on the left edge of the slide-over app. See this WWDC video. EDIT (Thanks to @qix, @Bogdan Weidmann, @Solomon) Supported devices: iPad Air+, Mini 2+ for slide over

Why are my variables empty when I cast them in my iOS application?

问题 Hi, I am coding an application on Xcode for IOS and I would like to send a variable to another ViewController. The problem is that when I want to send from the controller called "Step1" to set the label of my second view controller called "Step2" . To do this I proceed in this way in "Step 1" : guard let step2 = self.storyboard?.instantiateViewController(withIdentifier: Step2) as? EndConfiguration else { fatalError("Error when trying to get the reference to the Step 2") } step2

iPad GLSL. From within a fragment shader how do I get the surface - not vertex - normal

会有一股神秘感。 提交于 2020-12-10 06:33:43
问题 Is it possible to access the surface normal - the normal associated with the plane of a fragment - from within a fragment shader? Or perhaps this can be done in the vertex shader? Is all knowledge of the associated geometry lost when we go down the shader pipeline or is there some clever way of recovering that information in either the vertex of fragment shader? Thanks in advance. Cheers, Doug twitter: @dugla 回答1: You can get per-pixel normals interpolated from vertex normales by just using a

does the accelerometer work for the iphone/ipad simulator?

荒凉一梦 提交于 2020-12-06 06:43:50
问题 From what I can tell, my app should be firing accelerometer events while Im using the iPad simulator in XCode, but its not. I have googled around and it somewhat seems that the accelerometer is not implemented in the simulator, is this correct? If so, why on earth would they have a "Hardware->Shake Gesture" menu option? My code is as follows: .h file: @interface MyViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate, UIAccelerometerDelegate>{ UIAccelerometer

Safari for Ipad not reporting line numbers on Javascript errors

时光毁灭记忆、已成空白 提交于 2020-12-05 05:09:27
问题 I am using iPad 2 with IOs 5 to develop a web application. I have enabled the developer console to get logs , but when javascript error occurs it does not include corresponding line number. Since the web application handles touch and gesture events, I cannot test them on desktop version of the browser! Any help will be appreciated. 回答1: You can add a window level error handler http://dev.opera.com/articles/view/better-error-handling-with-window-onerror/ and have that console log the line
