  • appstore launch request unable to complete

    - by Joey
    I am trying to launch an appstore page with either of the calls: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunes.apple.com/us/app/myappname/id999999999?mt=8"]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.itunes.com/apps/myappname"]]; Both of these urls work when I enter them in a browser. However, from both simulator and device, I get a "Your request could not be completed" error dialog right after it appears to try to launch the appstore. Is there something obvious that I'm doing wrong?

    In a ruby on rails app, I build an array of Project Names and project id values, but want to truncate the length of the names. Current code is: names = active_projects.collect {|proj| [proj.name, proj.id]} I have tried to add a truncate function to the block, but am getting undefined method for class error. Thanks in advance - I just cannot wrap my head around this yet.

  • How to keep iPhone app out of iPad store?

    - by Eric
    I have an iPhone app that I have started to turn into a universal app, however the process is not complete and I want to release an update to the iPhone version. I know that you can specify device capabilities in the Info.plist file to restrict your app to certain devices, but how can I do this to prevent the unfinished universal version from appearing in the iPad store? Is checking the LSRequiresiPhoneOS BOOL entry (in the Info.plist file) enough? Thanks!

  • Is single float assignment an atomic operation on the iPhone?

    - by iter
    I assume that on a 32-bit device like the iPhone, assigning a short float is an atomic, thread-safe operation. I want to make sure it is. I have a C function that I want to call from an Objective-C thread, and I don't want to acquire a lock before calling it: void setFloatValue(float value) { globalFloat = value; }

  • Easiest way to export longitude and latitude data stored in a SQLite database to a file so it can be

    - by LordSnoutimus
    Hello, I have created an application that records a series of longitude and latitude values in a SQLite database and display them as a coloured track on a MapActivity. I now want to be able to export this data somehow (preferably to a file) so a user can upload the values to a website showing a Google Map API. My question is: what would be the quickest way to export the data (and in what file format: GPX, XML, CSV) to the SD card located on the Android device. Many thanks.

  • Background-image won't change using jquery in IE6

    - by slav
    There is a panel on my page with no default background-image css. On load it is set with jquery to an initial image, waits for 10 seconds then loads a random image out of some predetermined images. There are previous and next buttons which allow you to cycle through the images. In ie6 the initial image loads and then a random image also loads after 10 seconds, however pressing prev/next causes the background to become white and the images aren't loaded. With alerts I was able to find that it's still keeping track of the position and url of the image it's supposed to load, but just won't load it. Here is the code below. <script type="text/javascript"> var facts = new Array(); var position; $(document).ready(function() { <xsl:for-each select="$currentPage/ancestor-or-self::node[@level=1]/../node[@nodeName='Fun Fact Folder']/node"> facts[<xsl:value-of select="position()" />] = '<xsl:value-of select="." />'; </xsl:for-each> if(window.location.pathname == "/homepage.aspx" || window.location.pathname == "/") { $(".fun_facts_bg").css("background-image", "url(images/fun_fact_homepage.JPG)"); setTimeout("randomFact()",10000); } else { randomFact(); } }); function randomFact() { $("a.previous_button").css("display", "block"); $("a.next_button").css("display", "block"); position = Math.ceil(Math.random() * (facts.length - 1)); changeFact(0); } function changeFact(increment) { position = checkPosition(position, increment); $(".fun_facts_bg").css("background-image", "url(" + facts[position] + ")"); } <xsl:text disable-output-escaping="yes">&lt;!--//--&gt;&lt;![CDATA[//&gt;&lt;!-- function checkPosition(currentPos, increment) { currentPos = currentPos + increment; if (currentPos &gt; facts.length - 1) { currentPos = 1; } else if (currentPos &lt; 1) { currentPos = facts.length - 1; } return currentPos; } //--&gt;&lt;!]]&gt;</xsl:text> </script> <a class="previous_button" href="javascript:void(0);" onclick="changeFact(-1);"> <a class="next_button" href="javascript:void(0);" onclick="changeFact(1);">

  • Why AVCaptureSession output a wrong orientation?

    - by Peter
    Hey guys, So, I followed Apple's instructions to capture video session using AVCaptureSession: http://developer.apple.com/iphone/library/qa/qa2010/qa1702.html. One problem I'm facing is that even though the orientation of the camera / iphone device is vertical (and the AVCaptureVideoPreviewLayer shows a vertical camera stream), the output image seems to be in the landscape mode. I checked the width and height of imageBuffer inside imageFromSampleBuffer: of the sample code, and I got 640px and 480px respectively. Does anyone know why this's the case? Thanks!

  • build errors with Crypto++ on iphone

    - by Joey
    I am trying to build Crypto++ for iPhone but encountering issues. I managed to get it to build to the device by removing a few .asm files and test.cpp but two issues: 1) the simulator gets build errors relating to: {standard input}:13583:suffix or operands invalid for `call' 2) there are hundreds of warnings (kind of annoying) Has anyone gotten crypto++ to work on iphone and found a way to resolve these issues?

    I'm trying to implement GK's voice chat. I have the underlying network done over wifi instead of bluetooth. Between the simulator and my test device, I was able to accept the invitation. But immediately after, I get the call didNotStartWithParticipantID, with the following error: Error Domain=GKVoiceChatServiceErrorDomain Code=32002 UserInfo=0x3b286f0 "Network conditions prevented connection." Any ideas? What's causing this?

  • Inline HTML Syntax for Helpers in ASP.NET MVC

    - by kouPhax
    I have a class that extends the HtmlHelper in MVC and allows me to use the builder pattern to construct special output e.g. <%= Html.FieldBuilder<MyModel>(builder => { builder.Field(model => model.PropertyOne); builder.Field(model => model.PropertyTwo); builder.Field(model => model.PropertyThree); }) %> Which outputs some application specific HTML, lets just say, <ul> <li>PropertyOne: 12</li> <li>PropertyTwo: Test</li> <li>PropertyThree: true</li> </ul> What I would like to do, however, is add a new builder methid for defining some inline HTML without having to store is as a string. E.g. I'd like to do this. <% Html.FieldBuilder<MyModel>(builder => { builder.Field(model => model.PropertyOne); builder.Field(model => model.PropertyTwo); builder.ActionField(model => %> Generated: <%=DateTime.Now.ToShortDate()%> (<a href="#">Refresh</a>) <%); }).Render(); %> and generate this <ul> <li>PropertyOne: 12</li> <li>PropertyTwo: Test</li> <li>Generated: 29/12/2008 <a href="#">Refresh</a></li> </ul> Essentially an ActionExpression that accepts a block of HTML. However to do this it seems I need to execute the expression but point the execution of the block to my own StringWriter and I am not sure how to do this. Can anyone advise?
