  • Reading a Text file in xcode

    - by Nicolaj Zefting
    First off, I'm a complete beginner. This might be a stupid question, but here it goes: I'm currently working on an App than contains Latin texts that the users can view and read. I'm using Xcode 4 with the storybord function. Theway the app is built: user selects author - then the book - then app shows the text. I am kind of confused because i need to have various text files, depending on the users choice.

  • Image Size for Animation!

    - by taimur-hamza
    Hi Everybody, I m new to iphone app development and i need some help. I have a list of 30 images that i have to animate and display with 0.1 second interval. I put all the images in an Array using this imageletter.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"1.png"], ...... ,nil] And then animate it using these statements, [imageletter setAnimationDuration:16]; [imageletter startAnimating]; [NSTimer scheduledTimerWithTimeInterval:mytime target:self selector:@selector(StopAfterCertainTime) userInfo:nil repeats:NO]; Now the problem is that the size of each image is 8kb , it runs fine on iphone simulator but crashes on device. When i used 30 other images of 4kb each it runs fine both on simulator and device. Can anybody tell me what is the ideal size for such kind of task. Thanks

  • Writing my first blackberry app

    - by skyeagle
    I am contemplating writing my first blackberry app. I am fundamentally, a C/C++ programmer (not Java), can anyone provide some guidelines on the quickest route (i.e. shallowest learning curve) to writing a blackberry app? Any resources/links would be useful. As an aside: In an ideal world, I would like to write once and deploy for both Blackberry and the iPhone, but since I am targetting largely business people, I guess blackberry should be my target - right? Is it possible to write once and deploy on BOTH iphone and BB?

  • Length of text that can just fit into one screen without scrolling

    - by KailZhang
    I find some iphone book apps have such feature: One screen one page of text without scrolling. The text can just fit into the whole screen with linebreaks and indentations. I'm curious of how to implement this. How could I decide the length of text that just fit into the screen. And also, given the whole text, I can calculate out the number of pages. If this is not possible to be done on iPhone(runtime?), then is it possible to process the text before storing it in app? I mean I calculate how many pages I need(how to split the raw text), probably how many lines per page.

  • Can I change my Universal App to an iPad-only app without creating a new project in XCode?

    - by user428143
    Hi there, I've created an iPad game using the Universal App Xcode template. Since I'm in late with the iPhone/iPod Touch branch of the app, I've decided to submit the app only for iPad and to update the app to universal in a second time. Question: Do I have to create a new iPad project and copy there all the code and stuff, or can I simply change the deployment target to iPad only and I'm done? I simply want to be accepted and to avoid iPhone users to be allowed to download the game erroneously. Thank you!

  • Mobile web apps - Is this the right approach?

    - by Pasta
    I need to build a cross platform mobile app (iphone, android, etc). The app is for a company like a cellular operator (Tmobile, ATT). The app needs to do the following: Show previous bills (cached so that it does not have to download everytime) Need an internet connection to download newer bills, view recent data, etc. Can I build a mobile web app to handle this? I understand that there is offline storage and iPhone has good support for web apps (full screen, good icons, offline, etc). Will a web app be the best approach to take as the app requires to be online? The app will not be used by lots of people, just customers of the website who don't want to use an existing website. We are all web developers and a mobile web app looks like the best way to approach this.

  • How to detect mobile and tablet using CSS or JavaScript regardless of brands?

    - by user144966
    Basically what I'm trying to do is have 3 css stylesheets for desktop, mobile, and tablet. And I don't care if it is ipad or samsung galaxy tab as long as I know it is a tablet, so that I just apply tablet css to it. Same as iphone or Nexus which I don't care either. I just care about the dimension basically. That would be good if JQuery Mobile could do this. I know there is lots of code for detecting iphone, ipad, and etc, hope my post still makes sense. Thanks.

  • How to make a UILabel which adjusts it's text to the upper left?

    - by mystify
    For some strange reason, in iPhone OS 3.0 this doesn't work: I made a big fullscreen UILabel with numberOfLines = 0 and baselineAdjustment = UIBaselineAdjustmentNone. It refuses to show the text in the upper left. It's always in the center of the bounding box, aligned to the left. The documentation says: UIBaselineAdjustmentNone Adjust text relative to the top-left corner of the bounding box. This is the default adjustment. Available in iPhone OS 2.0 and later. Probably a framework bug? I started with shiny new labels to test it. Text is centered.

  • Unit testing of static library that involves NSDocumentDirectory and other iOS App specific calls.

    - by Shiun
    Hi, I'm attempting to run unit tests for a static library that attempts to create/write/read a file in the document directory. Since this is a static library and not an application for the iOS, attempts to reference the NSDocumentDirectory is returning me directory for the form "/Users//Library/Application Support/iPhone Simulator/Documents" This directory does not exist. When attempting to access a directory from an actual application, the NSDocumentDirectory returns something of the form: "/Users//Library/Application Support/iPhone Simulator/4.2/FEDBEF5F-1326-4383-A087-CDA1B865E61A/Documents" (Please note the simulator version as well as application ID as part of the path) How can I overcome this shortcoming in the unit test framework for static libraries that implement tests that require iOS app specific calls? Thanks in advance.

  • Storing acceleration values in Objective-C/Cocoa?

    - by ASchlaep
    Hi all, I'm writing for the iPhone and I'm trying to measure the time between maximum accelerations. Imagine you've attached your iPhone to an oscillating spring. What I want to do is measure the frequency of the oscillation. The way I am going about doing this is storing a certain number acceleration values (updated 20 times per second) in an NSMutableArray and comparing the current acceleration value with previous acceleration values. How do I add each updated acceleration value to the NSMutableArray and at the same time delete values from the back of the array as I don't need them any more? Thanks in advance!

I am using following code [OperationContract] [WebGet(ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "GetDate")] DateTime GetDate(); When I tried to call the method using Mozilla rest client I am able to get following result "/Date(1355116291037+0530)/" But the problem is when this method consume from the iPhone side we are getting another date time value( there is around 5:30 hours difference) . Any one have any idea regarding this issue,Please help me Thanks in advance

  • What am I (a beginner) losing, by choosing Cherokee over Apache for serving dynamic content?

    - by Bad Learner
    I am a complete beginner and am planning to setup a photo sharing site. This is the setup I am planning, basically for a start - - Cherokee (instead of Apache) for serving dynamic content (python-based application), and Nginx for serving static files. Since, I am a beginner, what have I, to lose? So, can someone, from your experience, please tell me, what I'd lose by choosing Cherokee over Apache for serving dynamic content in PHP/Python/whatever? Anything other than the fact that there's lot of documentation, many people who can help when there's an issue etc as Apache is well established and the most popular web server? Again, my intention is not to spurt a flame war here. Just wanted to know if Cherokee would be better than Apache in terms of performance, reliability, and speed, when it matters (peak load times). Also, I heard it's a lot faster than Apache in serving dynamic content, is it true?

  • Mac Mini's internet very slow, every other device fine (PC, iPhone, Xbox 360)

    - by alex
    I recently haven't used my Mac Mini for about 5 days (however it was left on). I seem to be able to connect and get great download / upload speeds through my PC, Xbox 360, iPhone and parents' laptop. However, my Mac Mini is very slow. OS X's Mail.app is downloading mail at 0.4kbps and then dropping to 0. Skype file transfers are doing the same. Browsing the net is a terrible experience. It is taking 30 seconds or more to download basic pages. All of my devices connect wirelessly to a Netgear router / modem. I have tried giving the Mac Mini a manual IP, and renew DHCP lease, as well as flush DNS in Terminal. I have also rebooted the router / modem twice, and the Mac Mini twice. Do you know what could be causing this? Thanks

  • Using international phone numbers on iPhone [closed]

    - by Cawas
    Spin off question Is it possible to hack a SIM card to add a javacard application on it (to properly format international numbers)? If yes, how? Original Question In my previous phone carrier I could just dial +55 11 99883655 and it would just work. Now I moved to a new carrier and it doesn't work anymore! When I dial the same international number it keeps saying the number isn't formated correctly. How can I get my iPhone to understand international numbering back again? I've got over 100 contacts with numbers stored in this format already, and I want to keep them that way. edit: I originally asked this question here, moved it to apple stackexchange and now I'm bringing a new one (hopefuly).

  • Setting font size of Closed Captions on iPhone

    - by forthrin
    Does anyone know if it's possible to control the font size on videos played in the built-in iPhone video player? The subtitles (or "Closed Captions") that are there by default are rather small. None of the attempts below change the font size at all: ffmpeg -y -i in.mkv -i in.srt -map 0:0 -map 0:1 -map 1:0 -vcodec copy -acodec aac -ab 256k -scodec mov_text -strict -2 -metadata title="Title" -metadata:s:s:0 language=eng out.mp4 sudo port install mplayer +mencoder_extras +osd mencoder in.mkv -sub in.srt -o out.mp4 -ovc copy -oac faac -faacopts br=256:mpeg=4:object=2 -channels 2 -srate 48000 -subfont-text-scale 10 -of lavf -lavfopts format=mp4 mp4box -add output.ttxt:hdlr=sbtl:size=50 output.mp4 Should we assume that iOS simply disregards size information, or has anyone ever seen styling of subtitles actually work on iOS? Anyone know how to make this work?

  • How did I get here? My route to Android, iPhone, Windows Phone 7, and interest in Mobile Devices

    - by Wallym
    I get asked all the time how/why I got interested in mobile and jumped on this fairly early.  I tend to give half answers because it wasn't just one thing that took me to mobile, but a whole host of separate ivents culminating in a specific event where I wasdoing market research in May/June 2008.  Let me throw out the events and the facts about me: I tend to like new, different, cool stuff.  I jumped on .NET early on.  I jumped on Ajax early on.  I don't jump on every new technology that comes down the road, I'm probably the only person on the planet that doesn't "get" MVC, though I acknowledge that a lot of people do and it solves a number of problems in the default settings of ASP.NET WebForms. I remember buying an early Windows CE device. It was interesting, but dang, this stylus thing sucks. After I lost my third stylus, i just gave up.  I got my first mobile phone in early 1999.  Reception was crappy, but I could see the value in being mobile. In 1999, I worked on a manufacturing systems project.  One piece of the projects was a set of handheld devices on the shop floor.  While the UI was a crappy DOS based, yes I said DOS as in Disk Operating System Version 6.22, I could see that the wireless world was a direction I wanted to be in. In 2000, Microsoft released the first public alpha of .NET.  Very cool stuff indeed.  One piece of the puzzle was a set of mobile controls for ASP.NET.  I build numerous test apps as well as mobile version using these mobile controls.  Now, the mobile UIs of the time were based on WML, which was crap. I could real all the analysis of mobile and read all about growth rates.  Now, you have to realize that growth rates can be impressive when dealing with small numbers, but I knew it was a comer. In our first book, I got talked out of mobile because of the line from the publisher "Wally, mobile doesn't sell." Blackberry was the dominant device of the mid 2000s.  Its users were referred to as "Crackberry addicts."  Unfortunately, the mobile development experience for native apps was crap and the web experience was fairly rough as well, but if they could get the ecosystem started, other phones and better blackberryies would come out.  I finally jumped into using a blackberry. Sometime around 2006, I heard "Wally, mobile doesn't sell" again.  Now, anyone that knows me knows that someone saying something like this to me means I'll keep trying it. The phones of the mid 2000s were moving to be more graphical, but there were too many that had this idea that they had to use a stylus.  Stylus suck.  They get lost too easily. I worked on a project in 2007 and 2008 for a startup trying to answer the question of "What is there to do where I am at?"  For some reason, they wanted to be tied to PCs.  As it became obvious that they were having problems, their investor asked us to do some market research and to figure out what the marketplace did want.  One of the important things that I figured out was the we lived in a mobile world and if you had a mobile app, it need to be on a mobile device, not tied to a desktop/laptop/netbook device.  If there was any single event, this was it - I was doing some market research and sat and talked to people in a bar/restaurant in Atlanta called "The Grove" on Lavista.  The consensus of the people that I talked to was that they wanted their data where ever they were at, laptop, pc, mobile, whereever. In 2007, Apple released the iPhone.  Wow, what an impressive device, even with all the problems of a 1st generation device.  I bought an iPod Touch 1st generation to understand touch better, one of the best decisions I ever made. I decided in late 2008, to make a move into cloud, for a number of reasons.  I was working on an example app.  In April, 2009, one of my friends at Microsoft said "don't mention my name with this, but you need an iPhone front end for this app."  How do you get on the iPhone.  Well, there are a number of ways including: ObjectiveC.  Its hard to teach an old dog new tricks, and this dog knows .NET, not ObjectiveC. HTML, web, javascript optimized interface.  yeah, this is possible. PhoneGap.  Now, this is interesting, take an html interface and get it to run on the iPhone, Android, Blackberry, and other platforms.  I thought that this way made the most sense for me until......... MonoTouch.  In May/June 2009, Novell announced a way for .NET/c# developers to write apps for the iPhone.  This is the way that made the most sense to me. Titanium by Appcelerator.  This is similar in concept to PhoneGap.  I haven't played with this much but do want to learn more about it. In July, 2009, I emailed one of my contacts at Wrox to see if they would be interested in a short MonoTouch ebook in their Wrox Blox format.  I fully expected another  response along the lines of "Wally, mobile doesn't sell."  The response I got was "Wally, iPhone is H O T, get started immediately, can you have this to me before Labor Day."  Not quite the response I expected.  Thankfully, we didn't make the Labor Day, first draft date. I kept pushing back because I had a feeling that things were not going to be quite as polished and feature rich as necessary.  After all, Novell doesn't have the resouces of Microsoft's developer division. The ebook shipped on November 30, 2009. On about December, 15, 2009, my editor emailed and said "Your ebook is selling really well, lets do a full book and it by March 1 so get started."  Thankfully, guys like Craig Dunn and Chris Hardy were interested along with Martin and Ror joinged us later on. I bought my wife an iPhone 3Gs in early 2010 to go along with all my iPod Touch devices. I tried to pretend in 2010 that I wasn't that interested in mobile and still had interest in the desktop technologies.  I love the technologies and continue to use them today, but that isn't where my interest is right now.  I'm just about all mobile all the time with my energies.  Our book shipped in the beginning of July, 2010 right in the middle of the Apple FUD.I've been looking at Mobile Web as a way around the AppStores and Apple FUD problems of 2010. With all the Apple self FUD, we became interested in Android.I went up to Dino Esposito at DevConnections in Las Vegas at introduced myself. I've always tried to keep up with what Dino has been doing. I was shocked, he wanted to meet me.  We must have talked for 1.5 hours. It was way more time than I deserved. If you get a chance, go and introduce yourself to Dino. He's a great guy. Microsoft released Windows Phone 7 in the Fall of 2010.  I'm not doing development on that platform at this time.  I think they have a very interesting user interface.  The devices are being positively reviewed.  For my purposes, the devices are limited at this point in time.  We'll see what 2011 brings as far as updates to the operating system.  I need multitasking/background processing and html5 in the browser. Add that as well as acceptance in the marketplace and I'll be more interested in the device. Obviosuly, I'm now working on a MonoDroid book . I own Android and iPhone/iOS devices.  I am currently working on some startup ideas and am exploring as much in that area as I can. For 2011, I'm planning on speaking at Android Developer's Conference (AnDevCon) and Mobile Connections.  I'm really excited about this. I have a couple of magazine articles coming out in 2011 on Android and iPhone development with the Mono technologies.is Mono "The Answer"? What's "The Question?" I think it will work for me.  It might work for you, it might not.  it depends on your situation.  Its the current horse that I am riding. I might find a better horse tomorrow. So, that's how I got here.  I'm in love with mobile.  Mobile native apps on the device as well as mobile web.  I'm into all this cool stuff.  Where are you at?
