  • In App Purchase Resources Security.

    - by jAmi
    Hi I am setting up in app purchase where user can buy different Sounds. Once bought, he can play those sounds in the App. The Sound files are all present in my Resources Folder and I just keep a record(in a plist) of the files that have been purchased. No If I right click on the IAP file and see its content I can see the Resources, hence any one can have those sounds without actually buying them. Is there a protected Bundle or something?

  • iPhone Analytics

    - by ACBurk
    With the recent changes in the SDK agreement, I am kinda confused if I'm able to put any type of analytics into my app. I don't want to do anything nefarious, just want to see which functionality of my app is getting used the most. I was looking at Google Analytic's mobile sdk to track the different views, just like page views but I have a feeling it is not allowed anymore. Can someone clear up if Google Analytics are still allowed; if not, are any analytics allowed?

  • Keyboard problem on iPhone OS 4.0 (8A248c)

    - by Newbee
    Hi! I have view with text field -- subclassed from UIAlertView. In the textFieldShouldReturn delegate I call resignFirstResponder for text field and dismissWithClickedButtonIndex for view. On the 3.x version everything fine, but on 4.0 keyboard still present on screen after view dismissing and doesn't disappear while app running. App compiled for 3.0 target and tested on 4.0 iPhone OS. One more thing - sometimes after dismissing alert - Done button on the keyboard replaces with Return button.. Any suggestions ?

  • How much memory is my iphone app using (from Simulator)

    - by Jonathan
    I know this has something to do with Instruments, but well it's kind of confusing and searching for Instruments on Google doesn't help much. I'd like to know how well my app runs, like how much memory it uses. I just don't know where to find something like: "As close as we can tell from the simulator you'll app will currently be using xx MBs of RAM on a real iphone device." I need help on how to get this information.

  • Installing 2 versions of app on one device

    - by dl
    I've got two branches of an iPhone app going. I would like to load them both onto my provisioned iPad at the same time. The iPad sees them as the same app though and writes over whichever one is currently installed. Does anyone have good system for loading two versions concurrently. Thanks!

  • Can get coordinates from iPhone simulator, but can't get coordinates from iPhone device

    - by iPhoneARguy
    Hi everyone, I've run into something of a mysterious bug (to me). I have some code to pick out the user's current location on the iPhone SDK. It works fine on the iPhone simulator, but when I try to run it on the actual device, I get a weird error. Here is the code (I am using ASIFormDataRequest to create a POST request): ASIFormDataRequest * request = [ASIFormDataRequest requestWithURL:url]; [request setPostValue:@"testauthor" forKey:@"author"]; [request setPostValue:[[NSNumber numberWithDouble:datum.location.coordinate.latitude] stringValue] forKey:@"latitude"]; NSLog(@"%f", datum.location.coordinate.latitude); NSLog(@"%f", datum.location.coordinate.longitude); [request setPostValue:[[NSNumber numberWithDouble:datum.location.coordinate.longitude] stringValue] forKey:@"longitude"]; [request setPostValue:datum.comment forKey:@"comment"]; On the simulator, NSLog does log both the latitude and longitude, but on the iPhone, it does not. Even stranger, when I go through with the debugger on the device, I try "po datum.location", I get <+###, -###> +/- 223.10m (speed 0.00 mps / course -1.00) @ 2010-05-02 22:18:37 -0400 (### replaced by my location) but when I do "(gdb) po datum.location.coordinate" I get: There is no member named coordinate. Do you guys have any idea why this might happen? Thanks in advance for your help!

  • Strategies for Synchronizing Data Between a Rails App and iPhone App

    - by jessecurry
    I've written many iPhone Applications that have pulled data from web services and I've worked on synchronizing data between an iPhone App and a Web Application, but I've always felt that there is probably a better way to handle the synchronization. I'd like to know what strategies you have used to synchronize data between your iPhone(read: mobile) Apps and your Rails(read: web) Applications. Are there any strategies that scale particularly well? How have you dealt with large amounts of data? (Do you use paged responses?) How do you make sure that data is not overwritten? Is there a reason to avoid Ruby on Rails? if so, can you suggest an alternative? What is better about the alternative? What strategies have failed? Why do you believe that those strategies failed? I would like to be able to keep all of the data modifications on the server, but the particular application I am about to start work on will need the ability to operate while disconnected from the network. The user will be able to update data on the mobile device and update data through the web application. When the user's mobile device connects to the server any local changes will be pushed to the server.

  • Your finger prints may unlock your iPhone and it’s digital wallets

    - by Gopinath
    The next version of iPhone is going to have a biometric sensor which may allow your finger prints to authenticate and authorize – unlock the device, sign in to an account, authorize a credit card transaction, etc . The iOS 7 beta 4 released couple of days ago had many traces of biometric software libraries embedded in the OS and they make it pretty clear that Apple is preparing a new iPhone with finger sensor. Biometric sensors are not something new in digital devices. Most of us have been already using them on your laptops to unlock the computers as well as to launch applications. Though these sensors are available in many devices, they are hardly reliable. My personal laptop has a biometric sensor and half of the time either it does not work or it does not recognize my finger prints. When works, it works like a charm and very easy to unlock my device. But Apple is known for delivering great products by nailing down technical challenges and blending technology with beautiful user interfaces.  They had been doing when Steve Jobs was leading the pack and hope his legacy will be carried forward by Tim Cook by delivering amazing products in coming months.  I expect iPhone finger sensors to work flawlessly.

  • Should Android and iPhone UI be different?

    - by Phonon
    I'm not completely new to developing apps, but I'm at a point where I'm trying to develop something and deploy it on several mobile platforms. To only concentrate on two major ones, suppose I'm developing an app for Android and iPhone and designing UI and the general user interaction architecture. Both platforms give guidelines as to how their UIs should work. For example, most iPhone apps have the Navigation Bar (the one that says Testing 1 and has a Back button) and an Icon Bar for navigating a program, while Android uses an Options Menu fetched via a Menu button and the "back" navigation is handled with the physical Back button on the device. I've seen many apps that try to force the same UI on every platform. For example, custom-building an iPhone style Icon Bar and putting it in their Android apps, but it just doesn't quite look right to me and it feels like it violates UI design guidelines somewhat. Are there any good design patters for implementing something sufficiently similar on both platforms, yet still platform-specific enough so that the user would not feel out of their comfort zone? What do people usually do in these situations?

  • ipad video format

    - by Mike
    When you use iTunes to sync your videos with the iPhone the videos are always saved with no more than 640 pixels wide, if I am not wrong. What about the iPad? What is the size of videos iTunes syncs with iPad? 1024x768? and what if the video has a dimension below 1024x768? Will it scale up? or will it keep the video at low res and scale when you play? The question is because I am using the MPMoviePlayerController and I need to know what resolutions to expect, so I can adjust the interface. thanks.

  • iPhone SDK Push Notification

    - by Craig
    I have setup push notifications in the apple developer panel and added the code to my application. It works fine on the phone using a development profile but if I use a distribution (ad-hoc) profile so that I can give it to a few users for testing it gives an error and crashes, the log gives the following error Code: Thu Jun 25 22:22:35 unknown SpringBoard[729] <Warning>: *** Assertion failure in -[SBRemoteNotificationServer registerApplication:forEnvironment:withTypes:], /SourceCache/SpringBoard/SpringBoard-919.5/SBRemoteNotificationServer.m:633 Thu Jun 25 22:22:35 unknown SpringBoard[729] <Error>: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'no connection found for environment production' I am using the following code in the app Code: [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)]; The thing I don't understand is why it works perfectly using a development profile but with ad-hoc it crashes. Does anyone know what would cause this?, I've tried changing lots of things to try and find the issue but have found nothing.

  • A simple way to implement pathfinding using bullet physics - iPhone SDK

    - by Dave
    Hi, I have bullet physics set up and working on the iPhone but now I want to implement some sort of path finding with it. The problem is I have no idea where to start, the level is pretty simple just a lot of pillars that I want the 'bad guys' to navigate around to get to the player character. Do you have any suggestions or are there any tutorials you recommend for pathfinding using this on the iPhone?

  • Cross-platform game development: ease of development vs security

    - by alcuadrado
    Hi, I'm a member and contributor of the Argentum Online (AO) community, the first MMORPG from Argentina, which is Free Software; which, although it's not 3D, it's really addictive and has some dozens of thousands of users. Really unluckily AO was developed in Visual Basic (yes, you can laugh) but the former community, so imagine, the code not only sucks, it has zero portability. I'm planning, with some friends to rewrite the client, and as a GNU/Linux frantic, want to do it cross-platform. Some other people is doing the same with the server in Java. So my biggest problem is that we would like to use a rapid development language (like Java, Ruby or Python) but the client would be pretty insecure. Ruby/Python version would have all it's code available, and the Java one would be easily decompilable (yes, we have some crackers in the community) We have consider the option to implement the security module in C/C++ as a dynamic library, but it can be replaced with a custom one, so it's not really secure. We are also considering the option of doing the core application in C++ and the GUI in Ruby/Python. But haven't analysed all it's implications yet. But we really don't want to code the entire game in C/C++ as it doesn't need that much performance (the game is played at 18fps on average) and we want to develop it as fast as possible. So what would you choose in my case? Thank you!

  • UITableView gives empty table, does not load data

    - by Alex L
    Hi, Everything works fine when the view that holds my table is the main (first) view. However, when it's not the first view and I switch into that view, my table does not load data and I get an empty table. Using NSLog I can tell that the program is not invoking numberOfRowsInSection and cellForRowAtIndexPath. I have <UITableViewDataSource, UITableViewDelegate>, IBOutlet UITableview *tableView all declared. They are also connected in the InterfaceBuilder. I tried using viewWillAppear and [tableView reloadData] but that did not help. I'm new to iPhone development and your help is appreciated!

  • size of view not changing after frame change

    - by MikeNelson
    I have managed to do pretty complex things on iPhone but I am always stuck with views, frames, bounds, and simple stuff that defies any logic and don't work as expected. I have a self.view in my code and it has a lot of subviews on it. At some point of the code, I need to reduce the frame vertically to a specific size and later put it back as before. Then I have this code: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.5]; // frame is changing to a newHeight (other parameters are the same as before) self.view.frame = CGRectMake (0, 0, originalWidth, newHeight); [UIView commitAnimations]; The result is simply, nothing. The view continues as before. The same size, the same position. No change. Why this kind of thing happens? how to solve that?

  • UIView Clipped By Statusbar until Autorotate

    - by TonyNeallon
    Hi There, Ive created a multiview application that uses multiple controllers to display and control views. The problem Im having is, when the simulator initially loads the view the header is partially covered by the bar at top of screen and the tool bar at the base is not touching the base of the screen. I used the Interface builder size attributes to control the view when the iphone rotates and it works perfectly. All smaps into place perfectly both in landscape and portrait mode AFTER a rotation but the problem is with the initial load before a rotation occurs. Your thoughts a much appreciated. Tony

  • JSON to Persistent Data Store (CoreData, etc.)

    - by Bryan Veloso
    All of the data on my application is pulled through an API via JSON. The nature of a good percentage of this data is that it doesn't change very often. So to go and make JSON requests to get a list of data that doesn't change much didn't seem all that appealing. I'm looking for the most sensible option to have this JSON saved onto the iPhone in some sort of persistent data store. Obviously one plus of persisting the data would be to provide it when the phone can't access the API. I've looked at a few examples of having JSON and CoreData interact, for example, but it seems that they only describe transforming NSManagedObjects into JSON. If I can transform JSON into CoreData, my only problem would be being able to change that data when the data from the API does change. (Or, maybe this is all just silly.)

  • Cannot play a recorded sound on device.

    - by B_
    I'm using the exact code from the iPhone Application Programming Guide Multimedia Support to use AVAudioRecorder to record a file to the disk and then AVAudioPlayer to load and play that file. This is working fine in the simulator but is not working on the device. The file gets loaded (we can see the NSTimeInterval) but does not play (play returns false). After it didn't work with the sample code from the website, we tried changing to a bunch of different codecs with no success. And of course, the sound is on. Thanks a bunch.
