  • iPhone SDK - How to display a photo taken with the camera inside a UINavigationController?

    - by dan
    This is my code so far: /* class: myViewController @interface myViewController: UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate> */ - (IBAction) getPicture { UIImagePickerController * picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; } - (void) imagePickerController:(UIImagePickerController *)thePicker didFinishPickingMediaWithInfo:(NSDictionary *)imageInfo { [[thePicker parentViewController] dismissModalViewControllerAnimated:YES]; UIImage *img = [imageInfo objectForKey:@"UIImagePickerControllerOriginalImage"]; self.myImageView.image = img; } So basically I'm trying to get a photo from the iPhone camera and display it in a UIImageView. This works perfectly fine as long the class myViewController is displayed as a standalone view. If I'm putting the View inside a UINavigationController the UIImageView won't display the image after taking one with the camera. But if I choose a picture from the library everything is fine again. So why does the UIImageView won't display a image taken with the camera inside a UINavigationController?

  • iPhone / Android: what protocol stacks do apps use for connecting to centralised services?

    - by Richard
    Hi All, Aplogies for the ignorant question, I have no experience with app development on any mobile platform. Basically what I want to know is what communication protocols do apps typically use for accessing/querying centralised services? E.g if I port a webapp/service to iPhone/Andriod, typically how would I access/query this web service in my app? E.g is it over HTTP, or are there other protocols? Also, presumably the GUI of an app is constructed with Apple/Andriod GUI libraries (in java? cocoa?). Can an app GUI be defined with HTML/javascript like a webpage? Sorry again for the pure noob questions. Thanks

  • How should I structure my iPhone OpenGL ES 1.1 game?

    - by Ryan
    I am building an iPhone OpenGL ES 1.1 game. I am using the OpenGL ES template provided by xcode. I am only using the ES1Renderer. I've coded some basic touch actions the user can take, and I've begun to think about the overall structure of the code. All I'm really doing is using C in the ES1Renderer.m for my entire game state. I have an array of bullet structs, an array on enemy structs, etc.. Besides using this structure, where my entire game state is in ES1Renderer.m as C arrays and structs, what other ways are there to structure the code? Should I be using C++ or Objective-C classes to represent the enemies so they are more modular? The main reason I ask this is because I don't normally code in C, C++ and Objective-C..so I am a little fuzzy on coming up with a good architecture here.

  • Run Iphone app in simulator from the terminal : how to set up iPhoneSim ?

    - by user142764
    Hi, I found this project which seems to make it possible to run an iPhone app from command line ! http://github.com/jhaynie/iphonesim Unfortunately there is almost no documentation and i'm stuck at building this project : I download all sources I run MakeFile and i get these errors : admin$ ./Makefile ./Makefile: line 4: -Werror: command not found ./Makefile: line 5: AppKit: command not found ./Makefile: line 6: Source/main.o: No such file or directory ./Makefile: line 11: .SUFFIXES:: command not found ./Makefile: line 12: .m.o:: command not found ./Makefile: line 13: -o: No such file or directory ./Makefile: line 15: all:: command not found ./Makefile: line 17: iphonesim:: command not found gcc-4.2: argument to '-o' is missing ./Makefile: line 20: clean:: command not found As anybody been able to build and use this project ?

  • What are all the special iPhone / iPod Touch HTML tags?

    - by scunliffe
    After peeking at the SO source, I noticed this tag: <link rel="apple-itouch-icon" href="/apple-touch-icon.png" /> Which after a quick Google revealed an Apple "favicon" type thing for display on your homepage ("WebClip Bookmark" to be exact). The only other one that jumps to mind is the: <input type="search" results="5"/> This type="search" causes the field to "inherit" the Apple search icon, and the optional results="x" enables a history of "x" keywords to be maintained. I'm therefore wondering, what other Apple/Safari (iPhone/iPod Touch) specific HTML tags and attributes are out there that I'm not aware of! Curious minds need to know!

  • Is it possible to prevent iPhone/iPad orientation changing in the browser?

    - by BoomShaka
    I've seen similar questions on this issue, but they are related to native apps. I build web apps for the iPhone/iPad that run in the browser (Safari). I was wondering if there is a way to prevent orientation change in the browser, perhaps via some meta tag. I know of the viewport meta tag which allows you to specify scale and zooming capabilities, so figured maybe there is something similar for orientation. I doubt it is possible, but I thought I'd just pop a question on here to see.

  • Data format for content heavy iPhone app - Plist or XML?

    - by Toby
    Hello, I'm building an iPhone app that is essentially a book, it will be bundled with a lot of text-heavy content. I considered bundling the data as XML and load it when the application starts but the XML would contain a lot of nested structures and be a bit of a pain to parse. Would it be better to use a plist? I'm concerned about memory usage and plists are loaded entirely into memory - can they be parsed in chunks? Is there a maximum size to a plist and how efficient are they? I'm not sure how big the bundled content is going to be yet but I should imagine it could be anywhere from 500k to 4MB. Thanks in advance.

  • Using UIImageViews for 'pages' in an iPhone/iPad storybook app?

    - by outtoplayinc
    I'm new to iPhone programming, and well, what seems obvious to me may seem silly to a seasoned coder. I did a few 'switching views' tutorials on Youtube, and basically, they seems to work nicely for adding pages to a storybook type app. You add a UIViewController and associated view for each page. My question is would this become insanely slow, or a memory hog if I continued this method for say....35+ pages? Each page would also have a sound file associated with it that would play narration when a page load and stops when we leave. Basically, think of a powerpoint type app, with sound, possibly animated image elements, next & back buttons. I'm probably thinking of this very simplistically, but that's where my experience is at for the moment. Any insight or tips as to better and or more efficient ways to proceed would be greatly appreciated.

  • Is it possible to talk to the iPhone simulator/device.

    - by Plumenator
    I need to automate the build/deploy process for my iphone applications from a script. I can use xcodebuild to build the project, then use Applescript to deploy and debug/run the application. Assuming the application will stop by itself after a while, I need to collect the generated logs for verification. But the problem is I have no way to know when the application ended from outside of the application itself. If the running time is fixed, I can again use Applescript to stop the application (Cmd+Shift+Enter). So there has to be a way to connect to the device/simulator and wait on the application somehow.

  • Detect at runtime which country's App Store my iPhone app was downloaded from?

    - by Mike McMaster
    I have a feature in my iPhone application that, for business reasons, should only be shown/available to customers in the US. If I want to release this app to App Stores outside the US, what's the best way to figure out which country I'm in without relying on user-defined settings such as language and locale? In my mind, the ideal solution is that there's some runtime property that can tell me which App Store country the app was downloaded from, and I can take action accordingly. Looking through the docs and searching the web, I'm not coming up with anything in this department. I don't expect the solution to be 100% foolproof as far as users not being in the country they say they're from, but as close as possible would be nice. I suppose one solution would be to make a separate build for a new product on the App Store and have two versions, one for the US and one for the others, but that doesn't seem ideal. I'm hoping it can be the same product on the App Store to prevent things like fragmentation of user reviews. Thanks in advance!

  • IPhone: Controllers, Delagates, DataSources, etc all in one class?

    - by MLS
    Hi All, I am learning iPhone programming. I am starting with a simple example of displaying recently used documents in a UITableView. What I am confused about is why do I need to have several classes and why cant I just use one? Example, My class is called RecentFileList. I need to implement controller, delegate and datasource as well as the actual table view. Can't I just do this all in my RecentFileList Class versus having to create a RecentFileListDelegate RecentFileListController, RecentFileListDataSource class, etc, etc. Related to this can one define a class like: @interface FileListView : NSObject <UITableViewDelegate> <UITableViewController> <UITableViewDataSource { // code } @end or would I just do the work to make my class a delegate and controller in init()?

  • from JS to iphone dev - what's the best language to start with?

    - by Enkai
    I am a total beginner and would like to eventually learn to develop for the iphone. I have just done a beginner's CS course where the language we learned was JavaScript. We studied basic concepts like: variables, arrays, loops (for,while,if,if..else..), properties and functions. I'm wondering if I am starting in the right/wrong place by following this book: Learn C on the Mac by Dave Mark? I have read a few chapters and am finding it a bit hard to get my head around the way that C works, for example the way that Strings are printed seems overly complicated as compared to JS. Do you think that JS was the wrong language to start off with and would I be better to go from JS straight to Objective-C rather than to C? I have tried to read up on previous threads on the merits/demerits of learning C first but haven't found any that relate JS to learning C/Obj C/ Cocoa. Any advice appreciated as I am very new to this. Thanks

  • iPhone/Safari: fixed div sticks in the middle of the page when coming back by "history.back(-1)"

    - by praegustator
    Having a problem with fixed div using iPhone's Safari. I know that in iOS 5 the functionality for position:fixed have been added. My div is positioned at the top of the screen and behave pretty good, anyway, there are some bugs during scrolling. But what actually makes me angry - it is the position of this div after coming back to the current page clicking on javascript:history.back(-1) link. The fixed div sticks in the middle of a screen. When I try to scrool, it jumps back on the right position. Is there any cure for the bug?

  • Can I learn the iPhone SDK and complete an app by September?

    - by Kuro
    Hi everyone, I'm wondering if it's realistically possible to learn the iPhone SDK and complete an app by the end of this summer. The app shouldn't be too difficult, it would just interact with my site's API and essentially just fetch, create, and edit resources. I already have a little experience with the SDK (and I'm comfortable with Objective-C), so I'm not completely new to it. Although here I things I don't know how to do and what I'd need to learn: Log in to my site using basic http authentication and store the user's username/password for all future requests Implement a toolbar at the bottom to navigate between different views Fetch and parse xml into list items Do POST/PUT requests to create/edit a resource on my server Are there any good resources available to learn how to do those tasks above? Thanks!

  • Facebook Connect in iPhone app: Able to have two sessions?

    - by TheGambler
    Does anyone know if you are able to have two sessions save in one iphone app? I don't mean two sessions active. I want to be able to let someone switch between facebook accounts in my app without having to logout and back in. To my understanding a sessions state is saved in user preferences and is resumed when you basically say [ session resume ]. What I'm wondering is if I can choose which session to resume based on the uid? If so then I can choose which session to resume. Thanks to all that reply.

  • How to change the name of an iPhone app?

    - by Robert Gould
    I began an iPhone project the other day with a silly development code name, and now I want to change the name of the project since its nearly finished. But I'm not sure how to do this with XCode, trying the obvious of changing the application's name in the pinfo, causes the signing process to go wrong (I think...) and my app won't launch giving me a Launcher error. I guess I could make a new project and copy paste everything over, but it seems so primitive, that I'm hoping for a more civilized solution. Thanks!

  • How can I combine multiple iPhone applications in to one application?

    - by Toret
    At the moment I have 2 completed iPhone applications. Both these applications must be contained in to one application. I can't have multiple apps on the app store and to avoid confusion among people using these apps I must have them contained to a single application that gives the user the capability to launch any application in the wrapper. How can I go about doing this. Some of the ideas that crossed my mind are: Building a Framework, or building a library. But Im not even sure if I'm heading in the right direction.

  • Allen for Umbraco - Upload photos from your iPhone - iPad and iPod Touch

    - by Vizioz Limited
    At last year's UK Umbraco Festival we gave a demo of our alpha version of Allen for Umbraco, at that stage the application only worked on an iPhone and was a very quick prototype to see what people thought.When we returned to our office the next day, we decided if we were going to release Allen for Umbraco into the wild we really should start again from scratch, the main two reasons for this were;First to ensure it was a truly Universal application ( i.e. it can be installed on an iPhone, iPad or iPod ) which looks and behaves differently depending on the device. The second reason was we really wanted the application to be the foundations of more than just image uploading for Umbraco, for this to be the case we ensured the new version was built following proven design patterns and with lots of unit tests so that we can easily extended it.We have lots of plans for future versions of Allen for Umbraco including adding iCloud support to keep all your settings in sync across your multiple Apple devices. We are also working on support for Umbraco 5 which should be release soon.When you download the App and setup your site, make sure you have a look at the Image Resizing settings, by default we have set these to resize your images to 512 pixels wide, however you can choose from a variety of different resizing methods (by Height, Width, Fit within a frame or the full size image).Also, by default when you select a photo you will see that the image is named with it's date and time stamp of when the photograph was taken (or the current date and time if the original date is not stored in your image). If you click on this name you can edit the name of your photo before it is uploaded.Finally, we are really keep to get your feedback, so within the App help section you will find a way to submit Suggestions and if needed, you can send up Support emails from within the App :)We hope you enjoy the first version of Allen for Umbraco and we look forward to bringing you lots of exciting additional functionality in the future!

  • IPhone track title

    - by woodbase
    If you have an IPhone, you probably know that the name in the playlist comes from the “Title”-attribute instead of the filename. Usually that is not a problem. But when I plug my IPhone to the car stereo the tracks are sorted alphabetically by the “title”-attribute. That becomes a problem when You have an e-book where each chapter starts with “Track 01”. You can manually update this in the file properties (from the context menu in Windows Explorer), but doing so for +200 tracks – no thank you :) The FileInfo-class does not contain a property for this special audio file attribute. However the problem is easily solved using TagLib. The method below, not optimized in any way - just solving the problem at hand, will set the “title”-attribute to the file name. private static void UpdateTitleAttr(string dirPath, string fileFilter)         {             var files = System.IO.Directory.GetFiles(dirPath, fileFilter);                         foreach (var file in files)             {                 var f = TagLib.File.Create(file);                 var newTitle = f.Name.Substring(f.Name.LastIndexOf(@"\") + 1);                 f.Tag.Title = newTitle;                 f.Save();                }         } So now I can hear e-books while driving :P

  • How to fix codesign when it says user cancelled the operation? (And I didn't)

    - by eipipuz
    I'm compiling an iPhone app meant to be Distributed. It's my first app so I followed the "iPhone Provisioning Profiles" instructions. Unfortunately it fails with this: CodeSign build/*_*_.app cd "/Users/videojuegos/Documents/*_*_" setenv IGNORE_CODESIGN_ALLOCATE_RADAR_7181968 /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /usr/bin/codesign -f -s "iPhone Distribution: ******" "--resource-rules=/Users/videojuegos/Documents/*_*_/build/*_*_.app/ResourceRules.plist" --entitlements "/Users/videojuegos/Documents/*_*_/build/Unity-iPhone.build/Distribution-iphoneos/Unity-iPhone.build/*_*_.xcent" "/Users/videojuegos/Documents/*_*_/build/*_*_.app" /Users/videojuegos/Documents/*_*_/build/*_*_.app: The operation was cancelled by the user. Command /usr/bin/codesign failed with exit code 1 I thought Keychain wasn't allowing Codesign to work but as far as I can tell that isn't the case. I also attempted running these commands from a terminal and it failed with this message: Users/videojuegos/Documents/*_*_/build/Unity-iPhone.build/Distribution-iphoneos/Unity-iPhone.build/*_*_.xcent: cannot read entitlement data I have made the xcode setting from scratch three times. Googled it. No results. I don't have any idea what else to try. Any suggestions?

  • SharePoint 2013 Developer Ramp-Up - Part 1

    Today I had a little spare time during the morning hours and I decided that after checking MVA that I'm going to query the available course material over at Pluralsight. Wow, thanks to fantastic corporations and acquisitions there are lots of courses available. Nicely split by SharePoint version as well as particular interest group. Additionally, I found a couple of online blogs and community sites that I'm going to visit regularly during the next couple of weeks. Today's resource(s) Of course, I'm "all in" for the latest developer resources: SharePoint 2013 Developer Ramp-Up - Part 1 - Understanding the Platform and Developer Experience SharePoint 2013 Developer Ramp-Up - Part 2 SharePoint 2013 Developer Ramp-Up - Part 3 SharePoint 2013 Developer Ramp-Up - Part 4 SharePoint 2013 Developer Ramp-Up - Part 5 SharePoint 2013 Developer Ramp-Up - Part 6 I guess, I'm going to stick to the Pluralsight library until the end of this week. We'll see... Anyway, apart from the video material I came across a couple of other websites which I'd like to list here, too. That's mainly for personal reference instead of bookmarking in the browser, I'll use my own blog for that purpose. Atkinson's SharePoint Blog Düsseldorfer Jung Doerflers SharePoint Blog SharePoint Community Absolute SharePoint The links are in no preferential order and I added them as soon as I found them. Most probably, I'm going to report about specific articles from those resources during this challenge. So, stay tuned and I try to provide more details on certain topics. Takeaway First contact with the 'real stuff' in order to get an idea about software development in Microsoft SharePoint and beyond. Unfortunately and as already expected, the marketing department over at Microsoft seemed to have nothing better to do than to invent new names and baptise literally the same product with every release. Luckily, the release cycles between versions have been three years (roughly) - 2007, 2010, and 2013. Nonetheless, there will be a lot of version-specfic issues to tackle during this learning phase. Especially, when it's about historical expressions like 'WSS'* like I had it yesterday... It's going to be exciting and demanding to catch up with roughly 6-7 years of development and changes. Okay, let's face it. * WSS stands for Windows SharePoint Services 3.0 which forms the 'core engine' of SharePoint 2007. Part 1 of Andrew Connell's series on SharePoint 2013 for developers provides a brief history and overview of the various product names and their relation to the actual SharePoint version. I guess, I might create a cheat-sheet or something comparable in order to reduce the level of confusion while reading through other material: SharePoint 2007 (aka SharePoint v3 aka SharePoint 12) Windows SharePoint Services (WSS) 3.0 Microsoft Office SharePoint Server (MOSS) 2007 .NET Framework 3.0, 32-bit or 64-bit OS SharePoint 2010 (aka SharePoint v4 aka SharePoint 14) Microsoft SharePoint Foundation (SPF) 2010 Microsoft SharePoint Server (SPS) 2010 .NET Framework 3.5 SP1, 64-bit OS only SharePoint 2013 Microsoft SharePoint Foundation (SPF) 2013 Microsoft SharePoint Server (SPS) 2013 .NET Framework 4.5, 64-bit OS only After this quick excursion it is getting more interesting. SharePoint 2013 has a number of Development Practices and Techniques under the hood, and it will be quite a decision process depending on the task requirements to choose the correct path to go. At the moment, the following two options seem to be my future fields of operation: Client-Side Object Model (CSOM) REST API and OData syntax As part of my job assignment, I see myself developing within Visual Studio 2012/2013. Most probably the client development in C# will be using CSOM but of course I'll keep an eye on the REST API, too. JavaScript has quite a momentum since a while and it would a shame to ignore this type of opportunity and possibilities.

  • Web Developer - How to enhance my skillset?

    - by atif089
    First of all pardon my English. I am not a native English speaker I have been a Web Developer for the past 4 years. In these 4 years I have spent my time on the internet to learn things. My current skillset comprises of HTML CSS PHP MySQL jQuery (I would not say js and rather say jQuery because I am good at using jQuery and bad with plain javascript.) The above things seemed like an easier part of my life as I quickly learned them. But now I would really like to enhance my skillset and I am pretty confused which way to move ahead considering that I have to learn things using the web and references on my own. Design My first option is towards design. Shall I get started with design and start using Adobe Illustrator, Photoshop, Flash, Flex. Designing along with my previous skills looks like a money maker to me. As both are co-related to each other when web design is considered. And its easier to learn the first 2 and I hope I can get tutorials for the last 2 as well. Marketing A lot of my existing clients asked me if I do SEO. So this looked as a good field to me as well. I cannot estimate the scope of SEO but I assume it has a long future. Since I am business minded as well and there are a lot of tutorials around, should I start with SEO, SEM, Social Media, PPC or whatever it consists of. Software Development The complex plight and hardest thing (perhaps) but the easiest way to find a decent job in my location. If I go for software development what platform should be that I should be ideally going after? Should it be C# for windows development, or ASP.NET (once again enhances my skill set), J2EE (there are a lot of jobs for J2EE developers here) or plain C and C++. Also I think it is difficult to learn software languages right from Hello World, using internet? I have no clue how I learned PHP but I am sort of a pro now, but these other languages seems like a disaster to me? I cant figure out the reason if its because PHP is easier or there was a lot of tutorials around for PHP. Anyways is it also possible to learn software development right from Hello World using the web? Database / Server (Linux) / Network Administration Seems like a job with a decent pay but less number of jobs and a bit harder to learn online. (not sure) What should be the right track I should move ahead. P.S - Age is not a constraint for me as I am between 20-21, and I come from an IT background. I know quite little basics about C (upto structures) C++ (upto objects, I was not able to understand templates) Core Java (some basics and OOP concept) RDBMS Visual Basic 6 (used to do this long back) UNIX (a bunch of commands like who, finger, chmod, ls and a bit of #bash) Or is there anything else that I left out? I need you guys to please give me a feedback and the reason why I should select that field.
