  • iPhone programming - problem with CoreFoundation forking, PLEASE for the love of god help! lol

    - by Tom
    Hello all, I've been working on an iPhone for several months. It's a 2d shooting game akin to the old Smash TV type games. I'm doing everything alone and it has come out well so far, but now I am getting unpredictable crashes which seem to be related to CoreFoundation forking and not exec()ing, as the message THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONA LITY_YOU_MUST_EXEC__ always shows up somewhere in the debugger. Usually it shows up around a CFRunLoopRunSpecific and is related to either a timer firing or _InitializeTouchTapCount. I cannot figure out exactly what is causing the fork to occur. My main game loop is running on a timer, first updating all the logic and then drawing everything with openGL. There is nothing highly complex or unusual. I understand you cannot make CF calls on the childside of a fork, or access shared memory and things like that. I am not explicitly trying to fork anything. My question is: can anyone tell me what type of activity might cause CoreFoundation to randomly fork like this? I'd really like to finish this game and I don't know how to solve this problem. Thanks for any help.

  • Weak linking on iPhone refuses to work

    - by Jonathan Grynspan
    I've got an iPhone app that's mainly targetting 3.0, but which takes advantage of newer APIs when they're available. Code goes something like this: if (UIApplicationDidEnterBackgroundNotification != NULL) [nc addObserver: self selector: @selector(irrelelvantCallbackName:) name: UIApplicationDidEnterBackgroundNotification object: nil]; Now, according to everything Apple's ever said, if the relevant APIs are weakly linked, that will work fine because the dynamic linker will evaluate UIApplicationDidEnterBackgroundNotification to NULL. Except that it doesn't. The application compiles, but as soon as it hits "if (UIApplicationDidEnterBackgroundNotification != NULL)" it crashes with EXC_BAD_ACCESS. Is this simply a matter of a compiler flag I need to set? Or am I going about this the wrong way?

  • How to overlay view over navigation controller bar?

    - by 0SX
    I've sorta got a little problem. I'm trying to add a popoverview to my app but part of the popoverview get's hidden by my navigation controller bar. How can I make my popoverview overlay over top of the navcontrollerbar? Here's an image of the problem: http://img593.imageshack.us/img593/4056/viewn.jpg Here's my code I'm working with: - (IBAction)onButtonClick:(UIButton *)button { if (self.popoverController) { [self.popoverController dismissPopoverAnimated:YES]; self.popoverController = nil; [button setTitle:@"Show Popover" forState:UIControlStateNormal]; } else { UIViewController *contentViewController = [[WEPopoverContentViewController alloc] initWithStyle:UITableViewStylePlain]; self.popoverController = [[[WEPopoverController alloc] initWithContentViewController:contentViewController] autorelease]; [self.popoverController presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES]; [contentViewController release]; [button setTitle:@"Hide Popover" forState:UIControlStateNormal]; } } Is there anyway to make this popover above the navigation controller bar? Here is the full source code what I'm working with https://github.com/werner77/WEPopover Hopefully someone knows how to fix this problem, Thanks in advance.

  • NSUndoManager grouping problem?

    - by anonymous
    I'm working on a barebones drawing app. I'm attempting to implement undo/redo capability, so I tell the view's undoManager to save the current image before updating the display. This works perfectly (yes, I understand that redrawing/saving the entire view is not incredibly efficient, but to solve this problem before attempting to optimize the code). However, as expected, when I 'undo' or 'redo', only the minute change is reflected. My goal is to have the whole finger stroke undone/redone. To do that, I told the undoManager to [beginUndoGrouping] in the [touchesBegan] method, and to [endUndoGrouping] in [touchesEnded]. That works for a bit, but after drawing a few strokes, the app crashes, and gdb exits with exc_bad_access. I'm very grateful for any insight you can give me. - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { mouseDragged = YES; currentPoint = [[touches anyObject] locationInView:self]; UIGraphicsBeginImageContext(drawingImageView.bounds.size); [drawingImageView.image drawInRect:drawingImageView.bounds]; CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextSetLineCap(ctx, kCGLineCapRound); CGContextSetLineWidth(ctx, drawingWidth); [drawingColor setStroke]; CGContextBeginPath(ctx); CGContextMoveToPoint(ctx, previousPoint.x, previousPoint.y); CGContextAddLineToPoint(ctx, currentPoint.x, currentPoint.y); CGContextStrokePath(ctx); [self.undoManager registerUndoWithTarget:drawingImageView selector:@selector(setImage:) object:drawingImageView.image]; drawingImageView.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); previousPoint = currentPoint; }

  • How to update a detailView in a splitViewController?

    - by pikebu
    Hello, I'm trying to update a detailView in a splitViewController. This is what I try: //Get the application delegate AppDelegate *delegate = [[UIApplication sharedApplication] delegate]; //Get the masterViewController MasterViewController *master = [delegate.splitViewController.viewControllers objectAtIndex:0]; This seems to work fine so far. Then I try to update a label in the detailViewController by doing this: master.detailViewController.myLabel.text = "someText"; But this doesn't work. (ignore the missing at sign in front of the "someText" - I have it, but it seems it's not allowed to put it in this forum.) So how is the right way to access the outlets of in the detailView? Thanks for help.

  • How to directly store SQLite data in XCode?

    - by Justin
    Hi guys: Searched on here and got some vague answers, so I thought i'd rephrase the problem to get some clearer answers- Right now I have an SQL Lite db that reads/parses information from a pre-formatted .txt file. When I open the app, there is a slight 'lag' as the iDevice parses the info, then gets fetched for the iDevice. I'm just wondering if there's any way to just 'save' all the information directly in the xCode so there's no lag/fetch time? Thank you.

  • How to change to a grouped table view in xcode without using Interface Builder

    - by Dave
    I have a table that I created within xcode so there is no nib file in this case. I want to make my table into the 'Grouped' style but im not sure how. I think it has somthing to do with the method below, the problem is Im not really sure how to call it, I do understand how methods work I'm just not too sure on where to start with this one: - (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)UITableViewStyleGrouped So could someone tell me how to call it? The problem is that its not a method I wrote its a built in one so I could put that line into my header file but how would I use it in my implementation file? Thanks guys,

  • handleOpenURL not called using a custom url schema in iPhone OS

    - by favo
    Hi, I have successfuly added my own url schemes to my App. The App correctly launches using the schemes. Now I want to handle the incoming data but the delegate is not called. It is an universal app and I have added the following function to both AppDelegates: - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { if (!url) { return NO; } NSString *URLString = [url absoluteString]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"test message", nil) message:URLString delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil]; [alert show]; [alert release]; return YES; } I am testing with a schema like: myapp://appalarm.com …and would expect to be appalarm.com in the URLString What is wrong with it? Thanks for your responses!

  • iPad: Displaying UIActionSheet with UIPickerView as subview

    - by E-Madd
    I'm in the process of migrating an iPhone app to a universal app. On one of my views, I present a UIActionSheet with a UIPickerView as a subview. On the iPhone this always worked just fine. Of course, on the iPad I had to change a little to present the ActionSheet in a popover control. Here's some psuedo-code to outline where I'm at... actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0,44,0,0)]; pickerView.delegate = self; pickerView.dataSource = self; pickerView.showsSelectionIndicator = YES; [actionSheet addSubview:pickerView]; if (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPad){ [actionSheet showInView:self.view]; [actionSheet setBounds:actRect]; }else{ [actionSheet showFromRect:buttonRect inView:[UIApplication sharedApplication].keyWindow animated:YES]; } The resulting popover on the iPad is very small and only the very top of the UIPickerView is visible. How can I set the size of the popover?

  • UILabel not updating

    - by iFloh
    Sorry the basic question, but this bugs me for a while now. I create a details view from a UITable and try to dynamically set its labels, but they are not updating: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { myObject *tmpObj = [[myObject objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]; myViewController *tmpVC = [[myViewController alloc] initWithNibName:@"NIBfile" bundle:nil]; [tmpVC.myLabel setText:tmpObj.myTitle]; // The debugger shows the text: myTitle = "myText" NSLog(@"%@", tmpVC.myLabel); // NSLog SHOWS NULL [self.navigationController pushViewController:tmpVC animated:YES]; [tmpObj release]; } any ideas why the value is not coming through?

  • Allowing user to select a UIPickerView row by tapping.

    - by camilo
    Hi. I'm trying to use a UIPicker View with a behavior somehow different of what's usually seen in iPhone code examples. What I want to do is to allow users to scroll through the picker contents, but not to select a picker's row automatically (using the "didSelectRow" method from picker's delegate). Instead, I want to allow the user to touch the center row of the picker, which gets highlighted, and becomes the selection. Is there any way to achieve this? Thanks in advance.

  • iPhone app: How to implement in-app purchased game levels

    - by Wonderflonium
    So, I understand that it's possible to set up in-app purchases for iPhone apps to purchase non-consumables like game levels. I understand the logic behind the purchase part, but what I don't understand is, how can I deliver the new game level. For example: I build an app that contains the first level and they purchase additional levels. Is it better to build all the other levels into the app and whenever they purchase the app, it unlocks it with a plist entry or something? That doesn't seem very update-able to me. Every time I come up with a new level, I'd have to update the app. So, what I don't understand then, is what is how do I package up a level and download it as a separate entity that can accessed by the game? Would the level just be some XML with images in a ZIP folder or something? How does the level get added to the game? What are best practices for this type of thing? I Googled and have found NOTHING about this. I'm a little bit confused by the concept and any help would be appreciated. I'm not looking for someone to write the game for me, I just need pointed in the right direction so I can develop it on my own.

  • NSOperation and UIKit problem

    - by Infinity
    Hello guys! I am doing my download with an object which was inherited from NSOperation. I have read the documentation and when my operation finished I must call the [self.delegate performSelectorOnMainThread:@selector(operationDidFinish:) withObject:self waitUntilDone:YES]; method. It needs to be called on the main thread, because the UIKit is not thread safe and the documentation says this in these non thread safe frameworks cases. In the delegate method I am drawing a pdf or an image, but because it is drawn on the main thread the User Interface is very laggy until the drawing is finished. Maybe can you suggest me a good way to avoid this problem?

  • iPhone GPS Development - Tips + Tricks

    - by Keith Fitzgerald
    Hello - I'm looking for some feedback, blog links, etc that offer some tips and tricks for iPhone GPS development. I've read and understand the API, I have my demo app up and running, etc but I have run into some "quirks" with gps on iphone. For example, it seems that you you will receive a lot less location updates when your iphone enters "power save" mode. I've read that you can combat this by playing music in your application [not sure if this is true]. It also seems that, terms of making a reasonable pedometer, you should filter out any reading with horizontal accuracies less than 20 meters. Does this sound right? Is there any kind of checklist out on the web for iphone gps gotchas? Thanks in advance.

  • how can I translate a NSString to NSData? And the data has the same content as the string

    - by someonemaybe
    NSString * theString=@"e88d"; NSData * data; // something I should implement NSLog(@"%@", theString); NSLog(@"%@",[data description]); I want the results of the two printings are the same. AES encryption and decryption: (1).The server: if the plaintext is :@"abcd"; the AES encrypted data(NSData data type) is :"d882830c dc892036 4345839f 13c7516a"; (2).in my local app, my code is : NSData*data=[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://..."]]; NSString * mystring= [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; However, to decrypt data successfully, I must got a data(NSData date type) which equals to "d882830c dc892036 4345839f 13c7516a".But it is the mystring (NSString data type) not the data(NSData data type) that equals to the right value. the encryption and decryption function both need a data(NSData data type) as input datas. (NSData*)AES128EncryptWithKey:(NSString*)key; (NSData*)AES128DecryptWithKey:(NSString*)key;
