  • Port Flash to iPhone

    - by LaGrad
    How hard would it be to port a flash game to the iPhone. Obviously Flash CS5 is no longer an options, I still would like to know if there's anything that can be reused? or do I have to write everything from scratch (Is Obj-C that different than ActionScript?) Is there any other shortcuts? Also, if anyone has done this before please share your experience.

  • iPhone App Development - UITableView DetailsView

    - by leo
    Hi, I have a UITableView with a list of items such as item1, item2, item3, item4 and so on. If I select on item1, it will go to the detail view of item1 (which is controlled by DetailsViewController). What I am trying to do is to add a button called "Next" on DetailsView. When clicked, the DetailsView will refresh and show item2. When clicked again, it will show item3 and so on. I have been searching high and low for that to implement. But to no avail. Many thanks in advance!!!

Should I do something more?

  • Any idea about an iPhone Accelerometer Library?

    - by medopal
    Have looked so long for a library specialized in dealing with iPhone Accelerometer but couldn't find anything. I have made some few sample apps, but none reaches a level of accuracy as in Labyrinth games for example, so any idea about a library for that? Or maybe an open source app? Would be better if it's integrated in a Physics library

  • iphone Memory gets freed in debug mode but not in release mode

    - by gdr
    I have been testing my iPhone debug build on both my device and simulator with activity monitor, leaks, and object allocations. The code is pretty well optimized so I have decided to test the release build. I went into the project Menu and set the target build to be release, I then added the necessary header paths that my app is using to the headers search paths and ran the release build on the device with the above mentioned instruments. What I have noticed now is that memory that was freed when I used the debug build does not get freed when using release version. There is one place in my App that I remove a scroll view with some images which frees up a significant amount of memory when I use the debug build, but no memory is freed up in that place when I use the release version. Does someone have any ideas where I need to start looking at? did I setup my release build wrong?

  • How to Key-Value-Observe the rotation of a CALayer?

    - by HelloMoon
    I can access the value like this: NSNumber* rotationZ = [myLayer valueForKeyPath:@"transform.rotation.z"]; But for some reason, if I try to KV-observe that key path, I get a compiler error. First, this is how I try to do it: [myLayer addObserver:self forKeyPath:@"transform.rotation.z" options:0 context:nil]; The compiler tells me: *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ addObserver: forKeyPath:@"rotation.z" options:0x0 context:0x528890] was sent to an object that is not KVC-compliant for the "rotation" property.' what I don't get is, why I can access that z value by KVC key path, but not add an observer to it. Does this make sense? How else could I observe the z value of that matrix? I don't care about the other values of the matrix. Only the z rotation. Any other way to access and observe it?

  • iPhone Development - Location Accuracy

    - by Mustafa
    I'm using following conditions in-order to make sure that the location i get has adequate accuracy, In my case kCLLocationAccuracyBest. But the problem is that i still get inaccurate location. // Filter out nil locations if(!newLocation) return; // Make sure that the location returned has the desired accuracy if(newLocation.horizontalAccuracy < manager.desiredAccuracy) return; // Filter out points that are out of order if([newLocation.timestamp timeIntervalSinceDate:oldLocation.timestamp] < 0) return; // Filter out points created before the manager was initialized NSTimeInterval secondsSinceManagerStarted = [newLocation.timestamp timeIntervalSinceDate:locationManagerStartDate]; if(secondsSinceManagerStarted < 0) return; // Also, make sure that the cached location was not returned by the CLLocationManager (it's current) - Check for 5 seconds difference if([newLocation.timestamp timeIntervalSinceReferenceDate] < [[NSDate date] timeIntervalSinceReferenceDate] - 5) return; When i activate the GPS, i get inaccurate results before i actually get an accurate result. What methods do you use to get accurate/precise location information?

  • Why is my Interface Builder wiring so bonkers and what can I do to straighten it out?

    - by editor
    I've been working on an iPhone application in XCode and Interface Builder of the Tab Bar project type. After getting a table view of topics (business sectors) working fine I realized that I would need to add a Navigation Control to allow the user to drill into a subtopics (subsectors) table. As a green Objective-C developer, that was confusing, but I managed to get it working by reading various documentation trying out a few different IB options. My current setup is a Tab Bar Controller with Tab 1 as a Navigation Controller and Tab 2 a plain view with a Table View placed into it. The wiring works: I can log when table rows are selected and I'm ready to push a new View Controller onto the stack so that I can display the subtopics Table View. My problem: For some reason the first tab's Table View is a delegate and dataSource of the second ta. It doesn't make sense to me and I can't figure out why that's the only setup that works. Here is the wiring: Navigation Controller (Sectors) is a delegate of Tab Bar Navigation Bar is a delegate of Navigation Controller (Sectors) View Contoller (Sectors) has a view of Table View Table View (in Navigation Controller (Sectors)) is a delegate of First View Controller (Companies) Table View (in Navigation Controller (Sectors)) is a dataSource outlet of First View Controller (Companies) First View Controller (Companies) First View Contoller (Sectors) has a view of Table View Table View (in First View Controller (Companies)) is not hooked up to a dataSource outlet and is not a delegate When I click the tab buttons and look at the Inspector I see that the first tab is correctly hooked up to my MainWindow.xib and the second tab has selected a nib called SecondView.xib. It's in the File's Owner of MainWindow.xib where I inherit UITableViewDataSource and UITableViewDelegate (and also UITabBarControllerDelegate) in the .h, and in the .m where I implement the delegate methods. Why does this setup only work when the Table View in my first tab (View Controller (Sectors)) is a delegate and dataSource of the second tab? I'm confused: why wouldn't it need to be hooked up to the Navigation Controller-enabled tab in which the Table View is seen (Navigation Controller (Sectors))? The Table View seen on the second tab has neither dataSource and is not a delegate. I'm having trouble getting a pushViewController to fire (self.navigationController is not nil but the new View Controller still doesn't load) and I suspect that I need to work out this IB wiring issue before I can troubleshoot why the Nav Controller won't push a new View Controller onto the stack. if(nil == self.navigationController) { NSLog(@"self.navigationController is nil."); } else { NSLog(@"self.navigationController is not nil."); SectorList *subsectorViewController = [[SectorList alloc] initWithNibName:@"SectorList" bundle:nil]; subsectorViewController.title = @"Subsectors"; [[self navigationController] pushViewController:subsectorViewController animated:YES]; [subsectorViewController release]; }

  • Bind any version of MySql.Data using the app.config

    - by Martin Kirsche
    How do I bind any version or a range of versions of an assembly by using the app.config? I'm currently binding the MySql.Data assembly like this: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1" applies-to="v2.0.50727"> <qualifyAssembly partialName="MySql.Data" fullName="MySql.Data, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d, processorArchitecture=MSIL"/> </assemblyBinding> </runtime> Any version of MySql.Data other than 6.2.2.0 is not working this way. The versions of this assembly are changing fast so I either want to bind any or all versions beginning with 6.2 to my application without changing the app.config each time.

  • iPhone Human Interface Guidelines question

    - by Kyle
    iPhone Human Interface Guidelines -- Do they apply for OpenGL games? GL games typically have custom buttons, custom lists, etc. Take the Quake player list for example, if ported, it wouldnt be a typical UI list object. Does this mean the reviewer in question would reject anything that wasn't using standard UI? Or, is there an exception for games.

  • Artificial Intelligence in online game using Google App Engine

    - by Hortinstein
    I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players...(you can probably guess the type of game im developing)

  • Out-Of-Memory while doing Core Data migration

    - by Kamchatka
    Hello, I'm migrating a CoreData model between two versions of an application. I was storing binary data as blobs in the previous version and I want to take them out of the blobs for performance. My issue is that during the migration it seems that Core Data loads everything into memory which leads to Low Memory Warnings and then to my app being killed. Apple documentation suggests the following : http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/vmCustomizingTheProcess.html#//apple_ref/doc/uid/TP40005510-SW9 However, it seems to rely on the fact that the large objects are applied different mapping. In my case, all the objects are basically the same and the same mapping has to be applied to each of them. I don't see in this case how I could apply their technique. How should I handle a migration with very large objects ?
