  • how to get the camera data

    - by beof
    Hello ,guys, My app needs to get the camera data from Iphone. In my ImagePickerController, there is overlayView drawing realtime indications. I use UIGetScreenImage() to get the screenshot, and I also dump overlayview to image, then I can restore the original Image based on these two images. if the overlayView is still, it works quite well, but if the overlayView keeps changing, UIGetScreenImage() can not keep up with it. For example,if the overlayView changes from a rectangle to a circle, then calling UIGetScreenImage() returns with a rectangle on top of it. Is there a way to get the realtime camera data? I really appreciate if someone could help.

  • How to avoid piracy in iPhone apps by server side validation?

    - by prathumca
    As par my app requirement, there is a couple of scenarios that I need to handle. Scenario 1: To avoid piracy, I want to include some piece of code, whose job is sending both IMEI and Serial number of IPhone. Scenario 2: At server side, I've a database, which has a list of both IMEI and Serial No info. Here I wanna validate both IMEI and Serial numbers. If both are not matched then I can make sure that the app is pirated. Idea seems good. But I don't know how to handle these two scenarios in my app. Any help is greatly appreciated.

  • How can I run an app's source code that I got from the Android source code?

    - by Wesley
    For all of you android devs out there that have the Android simulator running on your comp, you know that there are a few built in apps that are already 'installed' on your phone. I had an idea for an app that would utilize a function that is already being done in the spare parts app. I went on to the android developer site, dug through the source code files, and found the spare parts app, and am now trying to set it up so that running it from eclipse on my machine actually runs the app in the simulator. In other words, I want to be able to make changes to and adjust some of the things in that app for my own needs. But it won't compile, because of a number of different errors. How do I get that source code running on my local machine? Is there some special trick that I just dont know about? I thought that if I could get the source code than the rest would be easy, but it isn't being too easy. Any help here would be appreciated!!

  • Facebook writing on a wall problem - retrieves only null value.

    - by Viral
    hi all friends, I am making a game application in that I want to pass my score on wall of face book. I've completed all the things (the log in and message passing part) but when I passes the score via global variable, I am getting only null as a value and not the score that I want. Is there any way to pass data or string to Face book and write on a wall? My code is (void)viewDidLoad { static NSString* kApiKey = @"be60415be308e2b44c0ac1db83fe486b"; static NSString* kApiSecret = @"4f880c7e100321f808c41b1d3c813dfa"; _session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain]; score = [NSString stringWithFormat:@"%@",appDelegate.myTextView]; [_session resume]; [super viewDidLoad]; } whre score is NSString and myTextView is NSString in other viewcontrollerfile, And appDelegate is global variable. Any help?? thanks in advance.

  • Good way to cache data during Android application lifecycle?

    - by sniurkst
    Hello, keeping my question short, I have creating application with 3 activities, where A - list of categories, B - list of items, C - single item. Data displayed in B and C is parsed from online XML. But, if I go trough A - B1 - C, then back to A and then back to B1 I would like to have it's data cached somewhere so I wouldn't have to request XML again. I'm new to Android and Java programming, I've googled a lot and still can't find (or simply do not have an idea where to look) a way to do what I want. Would storing all received data in main activity A (HashMaps? ContentProviders?) and then passing to B and C (if they get same request that was before) be a good idea?

  • What is the difference between these two different lines of Objective-C, and why does one work and n

    - by jrtc27
    If I try and release tempSeedsArray after seedsArray = tempSeedsArray , I get an EXEC_BAD_ACCESS, and Instruments shows that tempSeedsArray has been released twice. Here is my viewWillAppear method: - (void)viewWillAppear:(BOOL)animated { NSString *arrayFilePath = [[NSBundle mainBundle] pathForResource:@"SeedsArray" ofType:@"plist"]; NSLog(@"HIT!"); NSMutableArray *tempSeedsArray = [[NSMutableArray alloc] initWithContentsOfFile:arrayFilePath]; seedsArray = tempSeedsArray; NSLog(@"%u", [seedsArray retainCount]); [seedsArray sortUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; [super viewWillAppear:animated]; } seedsArray is an NSMutableArray set as a nonatomic and a retain property, and is synthesised. However, if I change seedsArray = tempSeedsArray to self.seedsArray = tempSeedsArray (or [self seedsArray] = tempSeedsArray etc.), I can release tempSeedsArray. Could someone please explain simply to me why this is, as I am very confused! Thanks

  • Left with extra UITableViewCell after re-ordering

    - by Mark F
    After going into Edit mode, moving a cell, and leaving edit mode, i am left with one extra cell sitting on top of its duplicate cell while still in edit mode. The problem has to be somewhere in here: - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath { NSMutableArray *array = [[fetchedResultsController fetchedObjects] mutableCopy]; id objectToMove = [[array objectAtIndex:sourceIndexPath.row] retain]; [array removeObjectAtIndex:sourceIndexPath.row]; [array insertObject:objectToMove atIndex:destinationIndexPath.row]; [objectToMove release]; for (int i=0; i<[array count]; i++) { [(NSManagedObject *)[array objectAtIndex:i] setValue:[NSNumber numberWithInt:i] forKey:@"userOrder"]; } [array release]; } Any guidance greatly appreciated!

  • ViewController has wrong orientation after Landscape-only has been popped

    - by noroom
    In a navigation-based app, LandscapeViewController only supports landscape mode (all others support both modes). I also have a "loading screen" that advises the user to rotate the phone before continuing. This way I can make sure that when my landscape view loads, that it's in landscape mode. The problem comes when i rotate the phone to portrait mode while still showing LandscapeVC. I press the Back nagivation button to navigate up one level (to a VC that supports both landscape and portrait modes), but the upper level shows in landscape mode even though the phone is in portrait mode. I guess this is because when I left this view I was in portrait mode, I then rotated the phone while in another view, so this view has not received the notification. If I then proceed to rotate the phone to the other landscape mode (say the LandscapeVC was loaded on its right side, so I'd rotate the upper VC from portrait to the left landscape mode), it will update. My question is: how can I notify this upper view that the phone was rotated, so when the user goes up after putting the phone in portrait mode, the upper view shows correctly?

  • changing sounds when objects meet

    - by blacksheep
    i'd like to change sounds when tapping on an image and drag another image over several others. it is not working properly: the "MoveImage" is not dragable, the tapping is working outside the "TouchImage" and the sounds do not change when tapping on it. (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if(((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)))) { [sound_E play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)))) { [sound_F play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)))) { [sound_D play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)))) { [sound_Dis play]; } } (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if (CGRectContainsPoint(myMoveImage.frame, location)){ CGPoint yLocation = CGPointMake(myMoveImage.center.x,location.y); myMoveImage.center = yLocation; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)) { E_NOTE.text = @"E"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)) { F_NOTE.text = @"F"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)) { D_NOTE.text = @"D"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)) { Dis_NOTE.text = @"D#"; } }

  • Playing audio from a wav file in iPhone SpeakHere example

    - by Mo
    I'm working with the iPhone SpeakHere example, and I would like to be able to play audio from either the mic (as in the example) or from a wav file. I have working code to play from a particular wav file, which looks like this: NSString *path = [[NSBundle mainBundle] pathForResource:@"basketBall" ofType:@"wav"]; AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio play]; So I'm fine with actually getting the wav to play in the application (I can hook it up to a button, etc.) but I would like it to also behave the same way pushing the "Play" button does after recorded speech, in that it should be connected to the same visualization (which I have modified quite a bit, but essentially shows the current volume, among other things). Thanks for your help!

  • Android App - disappearance of app GUI

    - by Radek Šimko
    I'm trying to create a simple app, whose main task is to open the browser on defined URL. I've created first Activity: public class MyActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.main); Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://my.url.tld")); startActivity(myIntent); } Here's my AndroidManifest.xml: <manifest ...> <application ...> <activity android:name=".MyActivity" ...> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> This code is fully functional, but before it opens the browser, it displays a black background - blank app GUI. I didn't figured out, how to go directly do the browser (without displaying the GUI). Anyone knows?
