  • Application creashing in saveAction of Coredata iphone sdk

    - by neha
    Hi all, In my application I'm inserting data using Coredata like this: GoodWork * newGoodwork = (GoodWork *)[NSEntityDescription insertNewObjectForEntityForName:@"GoodWork" inManagedObjectContext:self.managedObjectContext]; // Step 2: Set Properties [newGoodwork setEletitle:[NSString stringWithFormat:@"%@", aGoodwork.eletitle]]; [newGoodwork setEletxt:[NSString stringWithFormat:@"%@", aGoodwork.eletxt]]; [newGoodwork setSortId:[NSNumber numberWithInt:sortId]]; // Step 3: Save Object [self saveAction]; Everythinng is working fine but in saveAction which is: - (void)saveAction { NSError *error; if (![self.managedObjectContext save:&error]) { NSLog(@"Unresolved Core Data Save error %@, %@", error, [error userInfo]); exit(-1); } } My application is crashing after processing if condition. I'm not inserting all the fields in the entity "Goodwork". Can that be the reason? Thanx in advance.

  • 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?

  • Playing sounds in iPhone SDK?

    - by seanny94
    Does anyone have a snippet that uses the AudioToolBox framework that can be used to play a short sound? I would be grateful if you shared it with me and the rest of the community. Everywhere else I have looked doesn't seem to be too clear with their code. Thanks!

  • Custom view in iPhone SDK gets placed incorrectly in realation to statusbar

    - by markqvist
    (ragh, i'm apparently not allowed to post images, so i have included links to the images in this post instead of embedding them) Im writing an iPhone application based on the navigation controller template, but I am not loading the actual navigation controller as the first view in the window. I create a new view controller from a xib, and then add that as a subview, and then only push the navigation view as a modal when i need it. Here's my application: didFinishLaunching ... method in the application deleate RootViewController *rootViewController = (RootViewController *)[navigationController topViewController]; rootViewController.managedObjectContext = self.managedObjectContext; mainViewController = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:[NSBundle mainBundle]]; mainViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [window addSubview:[mainViewController view]]; [[mainViewController view] setNeedsLayout]; [window makeKeyAndVisible]; return YES; It works but the view is not properly aligned with the statusbar: http://img.exdev.dk/1.png When i click "my ambiances" and push the navigation controller view, and then dismiss it again, the layout is fine: same link as above, just replace the 1 with a 2. Sorry for the hassle, apparently I can also only post one link.... Here's the code I use for presenting/dismissing the navigationcontroller: -(void)pushMyAmbiences { [mainViewController presentModalViewController:navigationController animated:TRUE]; } -(void)returnToMainView { [mainViewController dismissModalViewControllerAnimated:TRUE]; } Is there anything I'm missing here? Layout-wise? Something that needs to be set in the xib? In a vain attempt I tried calling setNeedsLayout on the view, no luck. Any help is greatly appreciated!

  • Taking video from video camera and displaying it with MPMoviePlayerController IPhone SDK

    - by Daniel
    Has anyone tried taking a video from the camera and then using the video player provided to play it? When you take the video in portrait mode, sometimes the movie will play (when the player puts it in landscape mode) and when it puts it in portrait mode you cannot view the movie all you hear is sound,sometimes in landscape mode is flickers and does not play right, has anyone encountered this and found a way to fix it? My code to play the video looks like this: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *urls=[info objectForKey:@"UIImagePickerControllerMediaURL"] ; moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[info urls]]; if (moviePlayer) { [moviePlayer play]; } } I checked settings on the docs nothing seems like it would fix this...Thanks

  • iPhone SDK / Objective C Syntax Question

    - by Koppo
    To all, I was looking at the sample project from http://iphoneonrails.com/ and I saw they took the NSObject class and added methods to it for the SOAP calls. Their sample project can be downloaded from here http://iphoneonrails.com/downloads/objective_resource-1.01.zip. My question is related to my lack of knowledge on the following syntax as I haven't seen it yet in a iPhone project. There is a header file called NSObject+ObjectiveResource.h where they declare and change NSObject to have extra methods for this project. Is the "+ObjectiveResource.h" in the name there a special syntax or is that just the naming convention of the developers. Finally inside the class NSObject we have the following #import <Foundation/Foundation.h> @interface NSObject (ObjectiveResource) // Response Formats typedef enum { XmlResponse = 0, JSONResponse, } ORSResponseFormat; // Resource configuration + (NSString *)getRemoteSite; + (void)setRemoteSite:(NSString*)siteURL; + (NSString *)getRemoteUser; + (void)setRemoteUser:(NSString *)user; + (NSString *)getRemotePassword; + (void)setRemotePassword:(NSString *)password; + (SEL)getRemoteParseDataMethod; + (void)setRemoteParseDataMethod:(SEL)parseMethod; + (SEL) getRemoteSerializeMethod; + (void) setRemoteSerializeMethod:(SEL)serializeMethod; + (NSString *)getRemoteProtocolExtension; + (void)setRemoteProtocolExtension:(NSString *)protocolExtension; + (void)setRemoteResponseType:(ORSResponseFormat) format; + (ORSResponseFormat)getRemoteResponseType; // Finders + (NSArray *)findAllRemote; + (NSArray *)findAllRemoteWithResponse:(NSError **)aError; + (id)findRemote:(NSString *)elementId; + (id)findRemote:(NSString *)elementId withResponse:(NSError **)aError; // URL construction accessors + (NSString *)getRemoteElementName; + (NSString *)getRemoteCollectionName; + (NSString *)getRemoteElementPath:(NSString *)elementId; + (NSString *)getRemoteCollectionPath; + (NSString *)getRemoteCollectionPathWithParameters:(NSDictionary *)parameters; + (NSString *)populateRemotePath:(NSString *)path withParameters:(NSDictionary *)parameters; // Instance-specific methods - (id)getRemoteId; - (void)setRemoteId:(id)orsId; - (NSString *)getRemoteClassIdName; - (BOOL)createRemote; - (BOOL)createRemoteWithResponse:(NSError **)aError; - (BOOL)createRemoteWithParameters:(NSDictionary *)parameters; - (BOOL)createRemoteWithParameters:(NSDictionary *)parameters andResponse:(NSError **)aError; - (BOOL)destroyRemote; - (BOOL)destroyRemoteWithResponse:(NSError **)aError; - (BOOL)updateRemote; - (BOOL)updateRemoteWithResponse:(NSError **)aError; - (BOOL)saveRemote; - (BOOL)saveRemoteWithResponse:(NSError **)aError; - (BOOL)createRemoteAtPath:(NSString *)path withResponse:(NSError **)aError; - (BOOL)updateRemoteAtPath:(NSString *)path withResponse:(NSError **)aError; - (BOOL)destroyRemoteAtPath:(NSString *)path withResponse:(NSError **)aError; // Instance helpers for getting at commonly used class-level values - (NSString *)getRemoteCollectionPath; - (NSString *)convertToRemoteExpectedType; //Equality test for remote enabled objects based on class name and remote id - (BOOL)isEqualToRemote:(id)anObject; - (NSUInteger)hashForRemote; @end What is the "ObjectiveResource" in the () mean for NSObject? What is that telling Xcode and the compiler about what is happening..? After that things look normal to me as they have various static and instance methods. I know that by doing this all user classes that inherit from NSObject now have all the extra methods for this project. My question is what is the parenthesis are doing after the NSObject. Is that referencing a header file, or is that letting the compiler know that this class is being over ridden. Thanks again and my apologies ahead of time if this is a dumb question but just trying to learn what I lack.

  • iPhone sdk, at dismissModalViewcontrollerAnimated, the parent change y origin coordinate

    - by DigitalVanilla
    Hi guys, my first post here :) I'm having a small trouble with a small but boring problem. I have a view, with a NavigationController. I load in the NC a simple view. Inside this view there's abutton where I fire the presentModalView... in the main view, not on NC, but it's parent view: ABVIEW NC NEWVIEW new attach a presentModalView... on ABVIEW, so [abview present...]; No problem till now. When it's the time to dismiss, after the temporary window (let's calls it NOTES) disappear, my ABVIEW with all the subviews change Y position from 0 to 20, the same height of the status bar. I was looking everywhere and I'm sure it's a stupid thing, but I miss a bit of knowledge here and I have no idea where to find the solution. thanks in advance!

  • URLCache - iPhone SDK

    - by Kevin
    Hello everyone.. I need some help in using the NSURLCache to download a simple file. It would need to be saved in the Documents folder of the app. I have seen the URLCache example that apple presented, but I didn't find it useful since it was an image that was being shown. In addition there was some complex code on the modification date. I actually need something when the application opens it will begin the download process. Can someone guide me through just the download process of any file? Thanks Kevin

  • iPhone SDK background thread image loading problem

    - by retailevolved
    I have created a grid view that displays six "cells" of content. In each cell, an image is loaded from the web. There are a multiple pages of this grid (the user moves through them by swiping up / down to see the next set of cells). Each cell has its own view controller. When these view controllers load, they use an ImageLoader class that I made to load and display an image. These view controllers implement an ImageLoaderDelegate that has a single method that gets called when the image is finished loading. ImageLoader does its work on a background thread and then simply notifies its delegate when it is done loading, passing the image to the delegate method. Trouble is that if the user moves on to the next page of grid content before the image has finished loading (releasing the GridCellViewControllers that use the ImageLoaders), the app crashes. I suspect that this is because along the line, an asynchronous method finishes and attempts to notify its delegate but can't because it's been released. Here's some code to give a better picture: GridCellViewController.m: - (void)viewDidLoad { [super viewDidLoad]; // ImageLoader _loader = [[ProductImageLoader alloc] init]; _loader.delegate = self; if(_boundObject) [_loader loadImageForProduct:_boundObject]; } //ImageLoaderDelegate method - (void) imageDidFinishLoading: (UIImage *)image { [_imgController setImage:image]; } ProductImageLoader.m - (void) loadImageForProduct: (Product *) product { // Get image on another thread [NSThread detachNewThreadSelector:@selector(getImageForProductInBackground:) toTarget:self withObject:product]; } - (void) getImageForProductInBackground: (Product *) product { NSAutoreleasePool *tempPool = [[NSAutoreleasePool alloc] init]; HttpRequestLoader *tempLoader = [[HttpRequestLoader alloc] init]; NSURL *tempUrl = [product getImageUrl]; NSData *imageData = tempUrl ? [tempLoader loadSynchronousDataFromAddress:[tempUrl absoluteString]] : nil; UIImage *image = [[UIImage alloc] initWithData:imageData]; [tempPool release]; if(delegate) [delegate imageDidFinishLoading:image]; } The app crashes with EXC_BAD_ACCESS. Disclaimer: The code has been slightly modified to focus on the issue at hand.
