universal

问题 We're developing our first iPhone and iPad app with xcode 4.5.2. It is a universal app, with targeted device family = iPhone/iPad. Runs fine on simulators for iPhone and iPad but when distributed to Apple it only shows up in the app store on the iPhone. On the iPad app store . . . nothing. When you search for it online you can get the iTunes page in the browser (https://itunes.apple.com/us/app/episurveyor/id499388914?mt=8) but note that "Requirements: Compatible with iPhone 3G, iPhone 3GS,

问题 I am developing an universal app and using a ListView to display more than 50000 entries. I am using the following method to load the data: In the assets folder there's a simple utf-8 txt file with all the items (headwords of a dictionary in alphabetical order just to be precise). I load the file into an IList with ReadLinesAsync : IList<string> lista1 = await FileIO.ReadLinesAsync(listafile1); Finally I set the ItemsSource of the ListView to this IList: listView1.ItemsSource = lista1; It

问题 I'm having a difficult time finding the error I may have commit with GA. I developed a site http://farmacia-milenium.com.ar that used the default universal tracking code. For some reason the script is not working and I'm not tracking correctly. I do not know if some code of the site may interrupt the code performance. Could some one help me? Regards 回答1: Google Tag Assistant says the analytics.js script is not available and the console (in Google Chrome, that is) shows an error: Refused to

问题 I have a universal app with some localization. My problem is about splash screens. I need 6 splash screens. iPad, iPhone, iPhoneRetina (in English) and iPad, iPhone, iPhoneRetina (in Local Lang) I have a file for iPad English Splash, named "Default.png". When I select this file on project navigator, I can add localized version by clicking "+" sign. As a result I have 2 files: Default.png (English) and Default.png (Local Lang) So far eveything is ok. But when I try to add "Default~iphone.png"

问题 Which approach is good to create universal native application for iPhone/iPad: 1) Create separate NIB files for iphone and iPad versions and load the specific version by checking (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) . 2) Get the dimension of the main screen and frame the view accordingly CGRect mainWindow = [[UIScreen mainScreen] bounds]; UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, mainWindow.size.width, mainWindow.size.height)]; Please suggest if

问题 I notice when submitting a Universal app to the app store, there are various screen resolutions to support. I think iPhone/iPod: 320x460, 320x480, 640x960 and iPad 768x1024. When I specify Universal app development in Xcode, the simulator has a resolution of 320x480. To view 768x1024 screen resolution, I can change the target setting to iPad, but how to test 320x460 and 640x960 resolutions? My default solution is to target iPad, and manually hack my code, e.g.: SCREEN_WIDTH=640, SCREEN_HEIGHT

But it missing in window phone 8.1 runtime. 回答1: In Windows Phone 8.1 XAML apps you can use the FileOpenPicker to select am image either from the picture library, or from the camera. Make sure you have added ".jpg" to the picker file types, otherwise the camera button may not show. Here is sample code:

问题 Another hard goal (for me, of course) is the following: Goal ~(forall P Q: nat -> Prop, (exists x, P x) /\ (exists x, Q x) -> (exists x, P x /\ Q x)). Proof. I absolutely have no idea of what could I do. If I introduce something, I get a universal quantifier in the hypotesis, and then I can't do anything with it. I suppose that it exists a standard way for managing such kind of situations, but I was not able to find it out. 回答1: To progress in that proof, you will have to exhibit an instance

问题 I am trying to create a Window-based Universal app for iPhone/iPad. I used the Window-based template in XCode and it creates the necessary app delegate files for iPhone and iPad, but it also creates a xib file for each device, which I don't want to use -- I want to create my own views programmatically using my own view controllers, so I want to totally ignore the provided xib files. I deleted the xib files from the project and updated the plist file accordingly to not reference them, thinking
