  • Anyone know how do i get the real time feeds on gas station price in US via webservice version?

    - by tomtom
    Hi, Anyone has pointers on how to get real time US gas station feeds via webservice ? I'm trying to develop an iphone app that give users real time gas station price near their location. Currently i was wondering is there a legit government service that produce real time gas station price in the US on a daily basis? I heard about http://gasbuddy.com/ but i don't know where they get the data source from and was not sure if i should base on their data as well. On the other hand, there is a bunch of iphone apps on the apple store that show the gas price info. I'm clueless on how did the developers got their source from to get the nearest gas station price locations. Anyone has any suggestion? Thanks for the info :- )

  • Regular non-low energy bluetooth for IOS

    - by user3712524
    Ok, so I can't get my app to connect with a peripheral using bluetooth low-energy(my app is installed on an iPhone 5s and I have LightBlue installed on an iPhone 4S, simulating a peripheral. I also have light blue installed on the 5s, simulating a central, to verify that the two can connect and they do.) I have verified that the centralManager is instantiating and the State is powered on. So, my question is, is regular bluetooth still a viable option? Can I just use the GameKit API and go that route? Thanks in advance!

  • Unity has jerky motion when using Vector2.Lerp

    - by Sting Hà
    I made a 2D game with some sprite move to random position. I used Vector2.Lerp and Time.deltaTime to smooth transfer of sprite. When I build this game in iOS ( I used iPhone 4s and iPhone 5 for test ) all sprite made jerky motion and cause my game lagging. But in Android game run very smoothy. I used only 9 sprite and move all in same time. Can someone have any solution to fix this? Thanks. P/s: Sorry about my bad English.

    - 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!

  • 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?
