  • How do I reference my MainViewController from another class?

    - by todd412
    Hi, I am building an iPhone Utility app that uses UIImageView to display an animation. Within the MainViewController's viewDidLoad() method, I am creating an instance of a CustomClass, and then setting up the animations: - (void)viewDidLoad { [super viewDidLoad]; cc = [CustomClass new]; NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"image-1-off.jpg"], [UIImage imageNamed:@"image-2-off.jpg"], [UIImage imageNamed:@"image-3-off.jpg"], [UIImage imageNamed:@"image-4-off.jpg"], nil]; offSequence = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; offSequence.animationImages = imageArray; offSequence.animationDuration = .8; offSequence.contentMode = UIViewContentModeBottomLeft; [self.view addSubview:offSequence]; [offSequence startAnimating]; } That works fine. However, I would like to be able to move all the above code that sets up the UIImageView into my CustomClass. The problem is in the second to last line: [self.view addSubview:offSequence]; I basically need to replace 'self' with a reference to the MainControllerView, so I can call addSubview from within my CustomClass. I tried creating an instance var of CustomClass called mvc and a setter method that takes a reference to the MainViewController as an argument as such: - (void) setMainViewController: (MainViewController *) the_mvc { mvc = the_mvc; } And then I called it within MainViewController like so: [cc setMainController:MainViewController:self]; But this yields all sorts of errors which I can post here, but it strikes me that I may be overcomplicating this. Is there an easier way to reference the MainViewController that instanatiated my CustomClass?

  • OpenGL ES - how to keep some object at a fixed size?

    - by OMH
    I'm working on a little game in OpenGL ES. In the background, there is a world/map. The map is just a large texture. Zoom/pinch/pan is used to move around. And I'm using glOrthof (left, right, bottom, top, zNear, zFar) to implement the zoom/pinch. When I zoom in, the sprites on top of the map is also zoomed in. But I would like to have some sprites stay at a fixed size. I could probably calculate a scale factor, depending on the parameters to glOrthof, but there must be a more natural and straightforward way of doing that, instead of scaling the sprites down when I zoom in. If I add some text or some GUI elements on top of the map, they should definately have a fixed size. Is there a solution to do this, or do I have to leave fixed values in glOrthof and implement zoom/pinch in another way? EDIT: To be more clear: I want sprites that zoom in/out along with the map, but stay at the same size. I have some elements that are like the pins on the iPhone's map application. When you zoom, the pins stay the same size, but move around on the screen to stay on the same spot on the map. That is mainly what I want a solution for. Solutions for this already came below, thanks!

  • App crashes every second time a tableview row is selected in navigation controller setup

    - by Thaurin
    Disclaimer first: I'm pretty new to Objective-C and the retain model. I've been developing in a garbage collected .NET environment for the last five years, so I've been spoiled. I'm still learning. I'm having my iPhone app crash with EXC_BAD_ACCESS. It happens in a navigtation controller/tableview setup. When I select a row the first time, no problems. It switches in the child controller without problems. I go back and select the same row again. Program then proceeds to crash. Every other row works fine, but every second time a row is accessed, it's a crash. I've pinpointed the location where this happens. The child controller (which is a class that I reuse for every row of the same type) that's being switched into has an array of NSString's representing the rows that will be displayed. I set it before pushing the child viewcontroller. It's there where this apparently happens. I'm having a hard time debugging this problem, still wrestling with xcode and all. I fear there may be some vital information missing here, but maybe there is something you recognize here.

  • NSFetchedResultsController on secondary UITableView - how to query data?

    - by Jason
    I am creating a core-data based Navigation iPhone app with multiple screens. Let's say it is a flash-card application. The data model is very simple, with only two entities: Language, and CardSet. There is a one-to-many relationship between the Language entity and the CardSet entities, so each Language may contain multiple CardSets. In other words, Language has a one-to-many relationship Language.cardSets which points to the list of CardSets, and CardSet has a relationship CardSet.language which points to the Language. There are two screens: (1) An initial TableView screen, which displays the list of languages; and (2) a secondary TableView screen, which displays the list of CardSets in the Language. In the initial screen, which lists the languages, I am using NSFetchedResultsController to keep the list of languages up-to-date. The screen passes the Language selected to the secondary screen. On the secondary screen, I am trying to figure out whether I should again use an NSFetchedResultsController to maintain the list of CardSets, or if I should work through Language.cardSets to simply pull the list out of the object model. The latter makes the most sense programatically because I already have the Language - but then it would not automatically be updated on changes. I have looked at the NSFetchedResultsController documentation, and it seems like I can easily create predicates based on attributes - but not relationships. I.e., I can create the following NSFetchedResultsController: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name LIKE[c] 'Chuck Norris'"]; How can I access my data through the direct relationship - Language.cardSets - and also have the table auto-update using NSFetchedResultsController? Is this possible?

  • Save object in CoreData

    - by John
    I am using CoreData with iPhone SDK. I am making a notes app. I have a table with note objects displayed from my model. When a button is pressed I want to save the text in the textview to the object being edited. How do I do this? I've been trying several things but none seem to work. Thanks EDIT: NSManagedObjectContext *context = [fetchedResultsController managedObjectContext]; NSEntityDescription *entity = [[fetchedResultsController fetchRequest] entity]; NSManagedObject *newManagedObject = [NSEntityDescription insertNewObjectForEntityForName:[entity name] inManagedObjectContext:context]; [newManagedObject setValue:detailViewController.textView.text forKey:@"noteText"]; NSError *error; if (![context save:&error]) { /* Replace this implementation with code to handle the error appropriately. abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button. */ NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } The above code saves it correctly but it saves it as a new object. I want it to be saved as the one I have selected in my tableView.

  • problems getting HTTPRiot working

    - by bwizzy
    I've got an iphone app where I'm trying to use HTTPRiot to make some API calls to a web app. Problem is I can't see that none of the HTTPRiot delegate methods are being called.

  • Problem in calling a function from different class using protocols-iphone

    - by Muniraj
    I use cocos2d for my game. In which I play a movie and have a separate overlay view for controls.The touches are detected in the overlay view.

  • How do I reference an instance of a class using its tag?

    - by Matt Winters
    I have several instances of a UIControl class Foo being instantiated, one instance corresponding to each cell in a UITableView. The Class has: BOOL selected; UIImageView *imageView; UIImage *imageOne; UIImage *imageTwo; I've assigned each instance a tag: foo.tag = indexPath.row; I would now like to reference the UIImageView.image for a (or several) specific instance(s) by its tag to switch it to the other image. In my search I've seen things like classes being assigned tags using initWithTag (I assume they're assigning tags)... SomeClass *someClass = [[SomeClass alloc]initWithTag:1 ... [someArray addObject: [[SomeClass alloc]initWithTag:2 ... [someArray addObject: [[SomeClass alloc]initWithTag:3 ... ...but I haven't seen how they are later referenced by that tag. I have seen a reference to getChildByTag which had promise, but I can't find it in the documentation or examples (maybe not iphone). Does anyone know how reference the imageView.image within an instance using its tag? Thanks

  • Why is my view controllers view not quadratic?

    - by mystify
    I created an UIViewController subclass, and figured out that the default implementation of -loadView in UIViewController will ignore my frame size settings in a strange way. To simplify it and to make sure it's really not the fault of my code, I did a clean test with a plain instance of UIViewController directly, rather than making a subclass. The result is the same. I try to make an exactly quadratic view of 320 x 320, but the view appears like 320 x 200. iPhone OS 3.0, please check this out: UIViewController *ts = [[UIViewController alloc] initWithNibName:nil bundle:nil]; ts.view.frame = CGRectMake(0.0f, 0.0f, 320.0f, 320.0f); ts.view.backgroundColor = [UIColor cyanColor]; [self.view addSubview:ts.view]; like you can see, I do this: 1) Create a UIViewController instance 2) Set the frame of the view to a quadratic dimension of 320 x 320 3) Give it a color, so I can see it 4) Added it as a subview. Now the part, that's even more strange: When I make my own implementation of -loadView, i.e. if I put this code in there like this: - (void)loadView { UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 320.0f)]; v.backgroundColor = [UIColor cyanColor]; self.view = v; [v release]; } then it looks right. Now lets think about that: In the first example, I do pretty much exactly the same, just that I let UIViewController create the view on it's own, and then take it over in order to change it's frame. Right? So why do I get this strange error? Right now I see no other way of messing around like that to correct this wrong behavior. I did not activate anything like clipsToBounds and there's no other code touching this.

  • Problem with video playback on iPad with MPMoviePlayerViewController

    - by Symo
    Hello everybody... I have been fighting some code for about a week, and am hoping that someone else may have experienced this problem and can point me in the right direction. I am using the MPMoviePlayerViewController to play a video on the iPad. The primary problem is that it works FLAWLESSLY on the iPad Simulator, but will not play at all on the iPad. I have tried re-encoding the video to make sure that isn't an issue. The video I'm using is currently a 480x360 video encoded with H.264 Basline 3.0 with AAC/LC audio. The video plays fine on the iPhone, and also does play through Safari on the iPad. The video actually loads, and you can scrub through the video with the scrubber bar and see that it is there. The frames actually display, but just will not play. If you click play, it just immediately stops. Even when I have mp.moviePlayer.shouldAutoplay=YES set, you can see the player attempt to play, but only for a split second (maybe 1 frame?). I have tried just adding view with the following code: in .h ------ MPMoviePlayerViewController *vidViewController; @property (readwrite, retain) MPMoviePlayerViewController *vidViewController; in .m ------ MPMoviePlayerViewController *mp=[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:videoURL]]; [mp shouldAutorotateToInterfaceOrientation:YES]; mp.moviePlayer.scalingMode=MPMovieScalingModeAspectFit; mp.moviePlayer.shouldAutoplay=YES; mp.moviePlayer.controlStyle=MPMovieControlStyleFullscreen; [videoURL release]; self.vidViewController = mp; [mp release]; [self.view addSubview:vidViewController.view]; float w = self.view.frame.size.width; float h = w * 0.75; self.vidViewController.view.frame = CGRectMake(0, 0, w, h); I have also just tried to do a: [self presentMoviePlayerViewControllerAnimated:self.vidViewController]; which I actually can not get to orient properly...always shows up in Portrait and almost completely off the screen on the bottom, and the app is only intended to run in either of the Landscape views... If anybody needs more info, just let me know. I'm about at my wits end on this. ANY help will be GREATLY appreciated.

  • iPad application crash in Apple review - cannot replicate in simulator, have crash log

    - by Mike
    I am clearly missing something obvious here and would really appreciate some input. I have tried repeatedly to submit an application to Apple (iPad in this case) that is crashing on their end when testing but I cannot replicated the situation on my end (obviously I only have the damned simulator to work with at this point). The crash log is as follows: Date/Time: 2010-04-01 05:39:47.226 -0700 OS Version: iPhone OS 3.2 (7B367) Report Version: 104 Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x00000000, 0x00000000 Crashed Thread: 0 Thread 0 Crashed: 0 libSystem.B.dylib 0x000790a0 __kill + 8 1 libSystem.B.dylib 0x00079090 kill + 4 2 libSystem.B.dylib 0x00079082 raise + 10 3 libSystem.B.dylib 0x0008d20a abort + 50 4 libstdc++.6.dylib 0x00044a1c __gnu_cxx::__verbose_terminate_handler() + 376 5 libobjc.A.dylib 0x000057c4 _objc_terminate + 104 6 libstdc++.6.dylib 0x00042dee __cxxabiv1::__terminate(void (*)()) + 46 7 libstdc++.6.dylib 0x00042e42 std::terminate() + 10 8 libstdc++.6.dylib 0x00042f12 __cxa_throw + 78 9 libobjc.A.dylib 0x000046a4 objc_exception_throw + 64 10 CoreFoundation 0x00090c6e +[NSException raise:format:arguments:] + 74 11 CoreFoundation 0x00090d38 +[NSException raise:format:] + 28 12 Foundation 0x00002600 -[NSCFDictionary setObject:forKey:] + 184 13 iPadMosaic 0x00003282 -[iPadMosaicViewController getAlbumThumbs] (iPadMosaicViewController.m:468) 14 Foundation 0x000728fe __NSFireDelayedPerform + 314 15 CoreFoundation 0x00022d1c CFRunLoopRunSpecific + 2092 16 CoreFoundation 0x000224da CFRunLoopRunInMode + 42 17 GraphicsServices 0x000030d4 GSEventRunModal + 108 18 GraphicsServices 0x00003180 GSEventRun + 56 19 UIKit 0x000034c2 -[UIApplication _run] + 374 20 UIKit 0x000019ec UIApplicationMain + 636 21 iPadMosaic 0x00002234 main (main.m:14) 22 iPadMosaic 0x00002204 start + 32 My understanding here is that I am botching the Dictionary add somehow.

If retrieving the album cover fails for some reason the object is filled with a default image and then added. The last line of the code is what's showing up in the crash log. It runs fine in the simulator but crashes 100% in testing on device apparently. Can anyone tell me what I am missing here?

  • iPhone 3DES encryption key length issue

    - by Russell Hill
    Hi, I have been banging my head on a wall with this one. I need to code my iPhone application to encrypt a 4 digit "pin" using 3DES in ECB mode for transmission to a webservice which I believe is written in .NET. + (NSData *)TripleDESEncryptWithKey:(NSString *)key dataToEncrypt:(NSData*)encryptData { NSLog(@"kCCKeySize3DES=%d", kCCKeySize3DES); char keyBuffer[kCCKeySize3DES+1]; // room for terminator (unused) bzero( keyBuffer, sizeof(keyBuffer) ); // fill with zeroes (for padding) [key getCString: keyBuffer maxLength: sizeof(keyBuffer) encoding: NSUTF8StringEncoding]; // encrypts in-place, since this is a mutable data object size_t numBytesEncrypted = 0; size_t returnLength = ([encryptData length] + kCCBlockSize3DES) & ~(kCCBlockSize3DES - 1); // NSMutableData* returnBuffer = [NSMutableData dataWithLength:returnLength]; char* returnBuffer = malloc(returnLength * sizeof(uint8_t) ); CCCryptorStatus ccStatus = CCCrypt(kCCEncrypt, kCCAlgorithm3DES , kCCOptionECBMode, keyBuffer, kCCKeySize3DES, nil, [encryptData bytes], [encryptData length], returnBuffer, returnLength, &numBytesEncrypted); if (ccStatus == kCCParamError) NSLog(@"PARAM ERROR"); else if (ccStatus == kCCBufferTooSmall) NSLog(@"BUFFER TOO SMALL"); else if (ccStatus == kCCMemoryFailure) NSLog(@"MEMORY FAILURE"); else if (ccStatus == kCCAlignmentError) NSLog(@"ALIGNMENT"); else if (ccStatus == kCCDecodeError) NSLog(@"DECODE ERROR"); else if (ccStatus == kCCUnimplemented) NSLog(@"UNIMPLEMENTED"); if(ccStatus == kCCSuccess) { NSLog(@"TripleDESEncryptWithKey encrypted: %@", [NSData dataWithBytes:returnBuffer length:numBytesEncrypted]); return [NSData dataWithBytes:returnBuffer length:numBytesEncrypted]; } else return nil; } } I do get a value encrypted using the above code, however it does not match the value from the .NET web service. I believe the issue is that the encryption key I have been supplied by the web service developers is 48 characters long. I see that the iPhone SDK constant "kCCKeySize3DES" is 24. So I SUSPECT, but don't know, that the commoncrypto API call is only using the first 24 characters of the supplied key. Is this correct? Is there ANY way I can get this to generate the correct encrypted pin? I have output the data bytes from the encryption PRIOR to base64 encoding it and have attempted to match this against those generated from the .NET code (with the help of a .NET developer who sent the byte array output to me). Neither the non-base64 encoded byte array nor the final base64 encoded strings match.

    Exactly what the title says. Is it possible to use Facebook Connect (or any other means of FB integration) in a native iPhone app without resorting to the built in login dialog (which looks awful)? Something where I could create my own custom login screen asking for the facebook login username and password and then using the fbconnect native methods to validate that info and retrieve a valid session?
