  • Saving highscores coupled to a facebook account

    - by Eiko
    I want to offer a "highscore" list for friends in my app (at this point iPhone/iPad), so that if the user connected to facebook, he will get a list with his/her friends scores. Connecting is easy, retrieving friends is easy, but figuring out the best way to store the scores is not. As it seems I need to the store the scores on my own server server, no big deal. But what is considered a reasonable safe way to transfer the data? When communicating with facebook, authentication is clear - but communicating with my server basically anyone could post scores for another user if I send user id and score. Obfuscation might help a bit, but is there any better way to make sure that the data comes from the fb-logged-in person? Scores can also go down, so changing scores for other persons won't necessary help them. Thanks :)

  • UIImageView "Sprite Movement" How?

    - by Tate Allen
    Hi all, I am trying to make a game for the iPhone/iPod Touch. I am somewhat new to iPhone programming and extremely new to iPhone game programming so try to bear with me if this is a stupid question. How to I make my character, a UIImageView, move to the right or left, along the x axis. Just a simple translation across the screen. This is very frustrating so if you could link me to a tutorial or something like that, it would be much appreciated. Thanks in advance, Tate

  • Giving another object a NSManagedObject

    - by Wayfarer
    Alright, so I'm running into an issue with my code. What I have done is subclassed UIButton so I can give it some more infomormation that pertain to my code. I have been able to create the buttons and they work great. Capiche. However, one of the things I want my subclass to hold is a reference to a NSMangedObject. I have this code in my header file: @interface ButtonSubclass : UIButton { NSManagedObjectContext *context; NSManagedObject *player; } @property (nonatomic, retain) NSManagedObject *player; @property (nonatomic, retain) NSManagedObjectContext *context; - (id)initWithFrame:(CGRect)frame andTitle:(NSString*)title; //- (void)setPlayer:(NSManagedObject *)aPlayer; @end As you can see, it has a instance variable to the NSMangedobject I want it to hold (as well as the Context). But for the life of me, I can't get it to hold that NSManagedObject. I run both the @synthesize methods in the Implementation file. @synthesize context; @synthesize player; So I'm not sure what I'm doing wrong. This is how I create my button: ButtonSubclass *playerButton = [[ButtonSubclass alloc] initWithFrame:frame andTitle:@"20"]; //works playerButton.context = self.context; //works playerButton.player = [players objectAtIndex:i]; //FAILS And I have initilaized the players array earlier, where I get the objects. Another weird thing is that when it gets to this spot in the code, the app crashes (woot) and the the console output stops. It doesn't give me any error, and notification at all that the app has crashed. It just... stops. So I don't even know what the error is that is crashing the code, besides it has to do with that line up there setting the "player" variable. Thoughts and ideas? I'd love your wisdom!

  • Strange behaviour with mediaplayer and seekTo

    - by Mathias Lin
    I'm implementing a custom video player because I need custom video controls. I have an app with only one activity, which on startup shall start playing a video right away. Now, the problem I have is: I don't want the video to start from the beginning, but from a later position. Therefore I do a seekTo(16867). Since seekTo is asynchronous, I place the start call of the mediaplayer (player.start()) in the onSeekComplete of the onSeekCompleteListener. The strange behaviour I experience though is that I can see/hear the video playing from the beginning for a few millisecs before it actually plays from/jumps to the position I seeked to. But - on the other hand - the Log output I call before the player.start returns the correct position 16867, where I seeked to. Below is the relevant code section, the complete class is at http://pastebin.com/jqAAFsuX (I'm on Nexus One / 2.2 StageFright) private void playVideo(String url) { try { btnVideoPause.setEnabled(false); if (player==null) { player=new MediaPlayer(); player.setScreenOnWhilePlaying(true); } else { player.stop(); player.reset(); } url = "/sdcard/myapp/main/videos/main.mp4"; // <--- just for test purposes hardcoded here now player.setDataSource(url); player.setDisplay(holder); player.setAudioStreamType(AudioManager.STREAM_MUSIC); player.setOnCompletionListener(this); player.setOnPreparedListener(this); player.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() { public void onSeekComplete(MediaPlayer mediaPlayer) { Log.d("APP", "current pos... "+ player.getCurrentPosition() ); player.start(); // <------------------ start video on seek completed player.setOnSeekCompleteListener(null); } }); player.prepareAsync(); } catch (Throwable t) { Log.e(TAG, "Exception in btnVideoPause prep", t); } } public void onPrepared(MediaPlayer mediaplayer) { width=player.getVideoWidth(); height=player.getVideoHeight(); if (width!=0 && height!=0) { holder.setFixedSize(width, height); progressBar.setProgress(0); progressBar.setMax(player.getDuration()); player.seekTo(16867); // <------------------ seeking to position } btnVideoPause.setEnabled(true); }

  • Assign click event to addon icon on navigation bar

    - by Charsee
    We have created a chrome extension for our app. Where we call a METHOD from a "js file" on CLICK event of the "extension icon" placed on the navigation bar. For this we use message passing between the app.js (file containing the METHOD to be called on icon click) and background.html (using a js file included in this html). The script used to pass message is:(from background.html) chrome.browserAction.onClicked.addListener(function (tab) { chrome.tabs.sendMessage(tab.id, "showPopup"); }); and to listen the message :(in app.js) chrome.extension.onMessage.addListener(function(request) { if (request === "showPopup") { showPopup(); } }); The click event works as expected. But now we want to do same thing in mozilla extension. and we can't pass message to app.js on the click of the icon,so that it can execute the containing methods. We have also added the app.js using pageMod, something like this exports.main = function(options, callbacks) { pageMod.PageMod({ include: ["*"], contentScriptWhen: 'start', contentScriptFile: [data.url('jquery-1.7.1.min.js'),data.url('app.js')] }); createAndAddNavBarButton(); }; function createAndAddNavBarButton() { var navBar = document.getElementById('nav-bar');//assume document has been defined if (!navBar){return;}; var nbBtn = document.createElement('navbaricon'); nbBtn.setAttribute('id', 'navButton'); nbBtn.setAttribute('image', data.url('icon_16.png')); nbBtn.onclick = function(){ showPopup(); return true; } navBar.appendChild(btn); } But the click event does nothing and showPopup() is undefined. When a new page loads event associated with it in the app.js executes without any error but the click event doesn't work. Is there a method from where we can assign click event directly to this icon, as we have done in the case of chrome extension.

  • UIImagePickerControllerDelegate Returns Blank "editingInfo" Dictionary Object

    - by Leachy Peachy
    Hi there, I have an iPhone app that calls upon the UIImagePickerController to offer folks a choice between selecting images via the camera or via their photo library on the phone. The problem is that sometimes, (Can't always get it to replicate.), the editingInfo dictionary object that is supposed to be returned by didFinishPickingImage delegate message, comes back blank or (null). Has anyone else seen this before? I am implementing the UIImagePickerControllerDelegate in my .h file and I am correctly implementing the two delegate methods: didFinishPickingImage and imagePickerControllerDidCancel. Any help would be greatly appreciated. Thank you in advance! Here is my code... my .h file: @interface AddPhotoController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate> { IBOutlet UIImageView *imageView; IBOutlet UIButton *snapNewPictureButton; IBOutlet UIButton *selectFromPhotoLibraryButton; } @property (nonatomic, retain) UIImageView *imageView; @property (nonatomic, retain) UIButton *snapNewPictureButton; @property (nonatomic, retain) UIButton * selectFromPhotoLibraryButton; my .m file: @implementation AddPhotoController @synthesize imageView, snapNewPictureButton, selectFromPhotoLibraryButton; - (IBAction)getCameraPicture:(id)sender { UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; picker.allowsImageEditing = YES; [self presentModalViewController:picker animated:YES]; [picker release]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { NSLog(@"Image Meta Info.: %@",editingInfo); UIImage *selectedImage = image; imageView.image = selectedImage; self._havePictureData = YES; [self.useThisPhotoButton setEnabled:YES]; [picker dismissModalViewControllerAnimated:YES]; } - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker { [picker dismissModalViewControllerAnimated:YES]; }

  • Which audio playback technology do I need for this?

    - by mystify
    I have trouble choosing the right audio playback technology. There's a ton of technologies to use on the iPhone, it's so confusing. What I need to do is this: start playing short sounds ranging between 0.1 and 2 seconds high quality playback, no crackle (I heard some of the iPhone audio playback technologies do a crackle sound on start or end, which is bad!) ability to start playback of a sound, while there's already another one playing right now (two, three or more sounds at the same time) What would you suggest here, and why? Thanks :-)

  • Suggestions on implementing an iPad magazine app

    - by alku83
    I've been tasked with creating a magazine style app for iPad. Ideally it would look a little something like the Zinio app: http://www.zinio.com/ipad/ . This app is effectively a shell, allowing you to sample magazines (eg. read the first few pages) and select them for download. The magazines appear to have some sort of overlay, allowing you to interact with some things (eg. tap to watch a video). A few questions that come to mind: How would I go about delivering content to the user? In-app purchases aren't really an option, as some content will need to be delivered for free. Is it possible to download a package and make this available within the application? What format would be suitable for displaying the magazine? Sequential images, PDF, ebook? I'll need to have some form of interactivity. I guess I could have some form of lookup table, which would include information such as if the user taps on this page, within these coordinates, then launch this item. Anyone dealt with any similar issues?

  • How to use SMS content provider? Where are the docs?

    - by Mark
    Hi, I'd like to be able to read the system's SMS content provider. Basically I wanted to make an SMS messaging app, but it would only be useful if I could see past threads etc. It seems like there's a content provider for this, but I can't find documentation for it - anyone know where that is? Thanks -------- edit ----------- Ok I found a way to get the sms inbox provider, and I just dumped all the column names in that provider, looks like this: Uri uriSms = Uri.parse("content://sms/inbox"); Cursor c = context.getContentResolver().query(uriSms, null,null,null,null); // column names for above provider: 0: _id 1: thread_id 2: address 3: person 4: date 5: protocol 6: read 7: status 8: type 9: reply_path_present 10: subject 11: body 12: service_center 13: locked I'm just piecing this together from random threads I find around the net, I'm really wondering where this is all documented (if at all)? Thanks again

  • Get Object ID of UI element from code.

    - by andoriyu.mp
    I'm trying link 40 buttons to one event handler method and then do the processing work from one method instead of 40. I know how to link it but once I get there I don't know how to distinguish what button was pressed. Does anyone know how to reference the button object sender id or is there another way to solve this problem? Any help would be greatly appreciated.

  • Good guidelines for developing an ecommerce application

    - by kaciula
    I'm making an ecommerce application on Android and, as it is my first serious project, I'm trying to figure out beforehand the best approach to do this. The application talks to a web service (magento api, meaning soap or xml rpc unfortunately) and gets all the content on the phone (product categories, product details, user credentials etc.). I think it should do lazy loading or something like that. So, I was thinking to keep the user credentials in a custom Object which will be kept in a SharedPreferences so that every Activity cand easily access it. I'll use a couple of ListViews to show the content and AsyncTask to fetch the data needed. Should I keep all the data in memory in objects or should I use some sort of cache or a local database? Also, I'm planning to use a HashMap with SoftReferences to hold the bitmaps I am downloading. But wouldn't this eat a lot of memory? How cand all the activities have access to all these objects (ecommerce basket etc.)? I'm thinking of passing them using Intents but this doesn't seem right to me. Can SharedPreferences be used for a lot of objects and are there any concurrency issues? Any pointers would be really appreciated. What are some good guidelines? What classes should I look into? Do you know of any resources on the Internet for me to check out?

  • can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

    - by Wesley
    So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

  • Keyboard blocking my view

    - by John Smith
    I have a UIView with another UIView inside it. On the inside UIView there is a textbox which I want to fill in. When I try to fill it in the keyboard blocks my view: The UIViewController has the following containerView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds]; self.view=containerView; //The apropriate releases etc are further on... When I touch it, the keyboard comes up as expected, but blocks the textbox I'm trying to fill in. How can I force the view to slide up? The front view OptionsFront * fv = [[OptionsFront alloc] initWithFrame:[UIScreen mainScreen].bounds]; [containerView addSubview:frontView]; In the front view is a subview CGRect bounds = CGRectMake(0.0f, 210.0f, 280.0f, 130.0f); sv = [[UIView alloc] initWithFrame:bounds]; [self addSubview:sv]; //added to frontView In sv is a textbox near the botton: rect = CGRectMake(70.0f, 20.0f, 100.0f, 27.0f); cf = [self createTextField_Rounded:rect holder:@"+ve"]; [sv addSubview:cf]; So cf happens to be near the bottom of the page. I expected that when I select it, the whole display would move up, but the keyboard just moves up and blocks it. What can I do? Appendix: - (UITextField *)createTextField_Rounded:(CGRect) frame holder:(NSString *) ph { UITextField *returnTextField = [[UITextField alloc] initWithFrame:frame]; returnTextField.borderStyle = UITextBorderStyleRoundedRect; returnTextField.textColor = [UIColor blackColor]; returnTextField.font = [UIFont systemFontOfSize:17.0]; returnTextField.delegate = self; returnTextField.keyboardType = UIKeyboardTypeNumbersAndPunctuation; returnTextField.returnKeyType = UIReturnKeyDone; returnTextField.clearButtonMode = UITextFieldViewModeWhileEditing; return returnTextField; }

  • How do I add two alternating UITableViews to an existing UINavigationController view?

    - by Ron Flax
    I'm new to iPhone development and I am writing an iPhone app that needs two different table views, which are selectable using a button bar or tab bar. These table views are both the same size, but only cover about two thirds of the screen from the bottom up. The top portion of the screen remains the same when either of these tables is displayed. I'd also like to animate (flip) these views when the user selects one or the other. The view that these two tables will be displayed on is the detail view of my app where the user has already selected an item from the primary screen's table. I'm using a UINavigationController to manage the primary and detail views and I have this working. I also have the first of these two detail tables working as part of my detail view, but I think it makes more sense to isolate the code for these two tables and not duplicate all of the code for the part of the detail view that doesn't change. I don't really care how these two table views are created (either in code or via IB). I've tried several things and I can't seem to figure it out. Any help or ideas (with sample code) would be greatly appreciated!

  • Advanced Localization with Omission of Arguments in Xcode

    - by coneybeare
    I have this formatted string that I am having a translator work on. ENGLISH "Check out the %1$@ %2$@ in %3$@: %4$@" = "Check out the %1$@ %2$@ in %3$@: %4$@" GERMAN TRANSLATION "Check out the %1$@ %2$@ in %3$@: %4$@" = "Hör Dir mal %2$@ in %3$@ an: %4$@"; These are passed to a [NSString stringWithFormat:] call: ////////////////////////////////////// // Share Over Twitter NSString *frmt = NSLocalizedString(@"Check out the %1$@ %2$@ in %3$@: %4$@", @"The default tweet for sharing sounds. Use %1$@ for where the sound type (Sound, mix, playlist) will be, %2$@ for where the audio name will be, %3$@ for the app name, and %3$@ for where the sound link will be."); NSString *urlString = [NSString stringWithFormat:@"sounds/%@", SoundSoundID(audio)]; NSString *url = ([audio audioType] == UAAudioTypeSound ? UrlFor(urlString) : APP_SHORTLINK); NSString *msg = [NSString stringWithFormat: frmt, [[Audio titleForAudioType:[audio audioType]] lowercaseString], [NSString stringWithFormat:@"\"%@\"", AudioName(audio)], APP_NAME, url]; NSString *applink = [NSString stringWithFormat:@" %@", APP_SHORTLINK]; if (msg.length <= (140 - applink.length)) { msg = [msg stringByAppendingString:applink]; } returnString = msg; With the desired and actual outcome of: ENGLISH desired: "Check out the sound "This Sound Name" in My App Name: link_to_sound link_to_app" actual: "Check out the sound "This Sound Name" in My App Name: link_to_sound link_to_app" GERMAN desired: "Hör Dir mal "This Sound Name" in My App Name an: link_to_sound link_to_app" actual: "Hör Dir mal sound in "This Sound Name" an: My App Name link_to_app" THE PROBLEM The problem is that I was under the assumption that by using numbered variable in the NSLocalizedString, I could do things like this, where the %1$@ variable is completely omitted. If you notice, the German translation of the format string does not use the first argument (%1$@) at all but it ("sound") still appears in the output string. What am I doing wrong?
