  • Problem with saveToFile

    - by zp26
    Hi, I have a problem with a NSData writeToFile. I have implemented the code below but i have an anomaly. When i run my program on the simulator, the new file is created and the informations are stored; when i build the app in my device , the file isn't created. The debug don't give me any error but don/t save anything. Can you help me? Thanks so much and sorry for my english. -(void)saveXML:(NSString*)name:(float)x:(float)y:(float)z{ NSMutableData *data = [NSMutableData data]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [archiver setOutputFormat:NSPropertyListXMLFormat_v1_0]; [archiver encodeFloat:x forKey:@"x"]; [archiver encodeFloat:y forKey:@"y"]; [archiver encodeFloat:z forKey:@"z"]; [archiver encodeObject:name forKey:@"name"]; [archiver finishEncoding]; BOOL result = [data writeToFile:@"XML Position" atomically:YES]; if(result) [self updateTextView:@"success"]; [archiver release]; }

  • Running out of memory with UIImage creation on an offscreen Bitmap Context by NSOperation

    - by sigsegv
    I have an app with multiple UIView subclasses that acts as pages for a UIScrollView. UIViews are moved back and forth to provide a seamless experience to the user. Since the content of the views is rather slow to draw, it's rendered on a single shared CGBitmapContext guarded by locks by NSOperation subclasses - executed one at once in an NSOperationQueue - wrapped up in an UIImage and then used by the main thread to update the content of the views. -(void)main { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc]init]; if([self isCancelled]) { return; } if(nil == data) { return; } // Buffer is the shared instance of a CG Bitmap Context wrapper class // data is a dictionary CGImageRef img = [buffer imageCreateWithData:data]; UIImage * image = [[UIImage alloc]initWithCGImage:img]; CGImageRelease(img); if([self isCancelled]) { [image release]; return; } NSDictionary * result = [[NSDictionary alloc]initWithObjectsAndKeys:image,@"image",id,@"id",nil]; // target is the instance of the UIView subclass that will use // the image [target performSelectorOnMainThread:@selector(updateContentWithData:) withObject:result waitUntilDone:NO]; [result release]; [image release]; [pool release]; } The updateContentWithData: of the UIView subclass performed on the main thread is just as simple -(void)updateContentWithData:(NSDictionary *)someData { NSDictionary * data = [someData retain]; if([[data valueForKey:@"id"]isEqualToString:[self pendingRequestId]]) { UIImage * image = [data valueForKey:@"image"]; [self setCurrentImage:image]; [self setNeedsDisplay]; } // If the image has not been retained, it should be released together // with the dictionary retaining it [data release]; } The drawLayer:inContext: method of the subclass will just get the CGImage from the UIImage and use it to update the backing layer or part of it. No retain or release is involved in the process. The problem is that after a while I run out of memory. The number of the UIViews is static. CGImageRef and UIImage are created, retained and released correctly (or so it seems to me). Instruments does not show any leaks, just the free memory available dip constantly, rise a few times, and then dip even lower until the application is terminated. The app cycles through about 2-300 of the aforementioned pages before that, but I would expect to have the memory usage reach a more or less stable level of used memory after a bunch of pages have been already skimmed at fast speed or, since the images are up to 3MB in size, deplete way earlier. Any suggestion will be greatly appreciated.

  • Can't access annotation property of subclassed uibutton

    - by Tzur Gazit
    I have a mapView to which I add annotations. The pin's callout have a button (rightCalloutAccessoryView). In order to be able to display various information when the button is pushed, i've subclassed uibutton and added a class called "Annotation". @interface CustomButton : UIButton { NSIndexPath *indexPath; Annotation *mAnnotation; } @property (nonatomic, retain) NSIndexPath *indexPath; @property (nonatomic, copy) Annotation *mAnnotation; - (id) setAnnotation2:(Annotation *)annotation; @end Here is "Annotation": @interface Annotation : NSObject <MKAnnotation> { CLLocationCoordinate2D coordinate; NSString *mPhotoID; NSString *mPhotoUrl; NSString *mPhotoName; NSString *mOwner; NSString *mAddress; } @property (nonatomic, assign) CLLocationCoordinate2D coordinate; @property (nonatomic, copy) NSString *mPhotoID; @property (nonatomic, copy) NSString *mPhotoUrl; @property (nonatomic, copy) NSString *mPhotoName; @property (nonatomic, copy) NSString *mOwner; @property (nonatomic, copy) NSString *mAddress; - (id) initWithCoordinates:(CLLocationCoordinate2D)coordinate; - (id) setPhotoId:(NSString *)id url:(NSString *)url owner:(NSString *)owner address:(NSString *)address andName:(NSString *)name; @end I want to set the annotation property of the uibutton at - (MKAnnotationView *)mapView:(MKMapView *)pMapView viewForAnnotation:(id )annotation, in order to refer to it at the button push handler (-(IBAction) showDetails:(id)sender). The problem is that I can't set the annotation property of the button. I get the following message at run time: 2010-04-27 08:15:11.781 HotLocations[487:207] *** -[UIButton setMAnnotation:]: unrecognized selector sent to instance 0x5063400 2010-04-27 08:15:11.781 HotLocations[487:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIButton setMAnnotation:]: unrecognized selector sent to instance 0x5063400' 2010-04-27 08:15:11.781 HotLocations[487:207] Stack: ( 32080987, 2472563977, 32462907, 32032374, 31884994, 55885, 30695992, 30679095, 30662137, 30514190, 30553882, 30481385, 30479684, 30496027, 30588515, 63333386, 31865536, 31861832, 40171029, 40171226, 2846639 ) I appreciate the help.

  • Should an NSLock instance be "global"?

    - by Alex Reynolds
    Should I make a single NSLock instance in the application delegate, to be used by all classes? Or is it advisable to have each class instantiate its own NSLock instance as needed? Would the locking work in the second case, if I, for example, had access to a managed object context that is spread across two view controllers?

  • Why are my CATransitions acting up?

    - by Regan
    I am using the following code to switch between views with CATransition. CATransition *applicationLoadViewIn = [CATransition animation]; [applicationLoadViewIn setDuration:20]; [applicationLoadViewIn setType:kCATransitionPush]; [applicationLoadViewIn setSubtype:kCATransitionFromTop]; [applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; ViewToSwitchTo *myviewcontroller = [[ViewToSwitchTo alloc] init]; [self.view.layer addAnimation:applicationLoadViewIn forKey:kCATransitionPush]; [self.view addSubview:myviewcontroller.view]; It functions mostly how I want it to. It pushes from the top like it should, however it for some reason acts strangely. First, the view I am switching to starts coming in from the bottom like it should, but for some reason, the view that I am switching FROM appears over the top of it with low opacity, so you see both of them. However, you also see the view that is coming in, shifted maybe 100 pixels upwards, on top of itself and the other view, once again with low opacity. Just before the halfway point of the the transition, everything works fine, you only see the view that is coming in and the view going out, doing what they should be doing. But slightly after the halfway point, the view I am switching to appears in its final destination, under the view I am switching from, and the view I am switching from has been reduced in opacity. What is going on here?

  • Why does presentModalViewController not always work?

    - by E-Madd
    My application requires data from a server in order to run. The first thing it does is displays a view controller (LoadingViewController) that is responsible for checking if the data is saved to my PersistentStoreCoordinator. If the data isn't cached locally, it gets it from my server and caches it, and posts a notification that the LoadingViewController is listening for. When that notification comes through, LoadingViewController presents the application's MainViewController using the presentModalViewController with a flip animation. So far, so good... no errors. However, if the application loads and determines the data IS cached - the presentModalViewController does not work and the main application view never appears. No errors. I've even gone as far as adding a button to the Loading view that executes the same code when pressed and the damn thing works. I'm suspicious it has something to do with the timing of it all but I'm clueless as to what I can do to ensure the view is displayed with that flipping animation if the data is already cached locally. Any suggestions?

  • Apple Push Notifications With Foreign Accent Characters Not Receiving

    - by confeng
    I'm sending push notifications and when the message contains foreign characters (Turkish in my case) like I, s, ç, g... The message does not arrive to devices. Here's my code: $message = 'THIS is push'; $passphrase = 'mypass'; $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', 'MyPemFile.pem'); stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase); // Open a connection to the APNS server $fp = stream_socket_client( 'ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx); if (!$fp) exit("Failed to connect: $err $errstr" . PHP_EOL); echo 'Connected to Apple service. ' . PHP_EOL; // Encode the payload as JSON $body['aps'] = array( 'alert' => $message, 'sound' => 'default' ); $payload = json_encode($body); $result = 'Start'.PHP_EOL; $tokenArray = array('mytoken'); foreach ($tokenArray as $item) { // Build the binary notification $msg = chr(0) . pack('n', 32) . pack('H*', $item) . pack('n', strlen($payload)) . $payload; // Send it to the server $result = fwrite($fp, $msg, strlen($msg)); if (!$result) echo 'Failed message'.PHP_EOL; else echo 'Successful message'.PHP_EOL; } // Close the connection to the server fclose($fp); I have tried encoding $message variable with utf8_encode() but the message received as "THÝS is push". And other ways like iconv() didn't work for me, some of them cropped Turkish characters, some didn't receive at all. I also have header('content-type: text/html; charset: utf-8'); and <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> in my page. I don't think the problem appears while I set the value but maybe with pack() function. Any ideas to solve this without replacing characters with English?

  • InApp Purchase on slow network

    - by Chandan Shetty SP
    My InApp purchase code works fine in normal network, but in very slow network(safari browser will take 5 min to load a webpage). I am not getting any delegates... - (void)requestDidFinish:(SKRequest *)request - (void)request:(SKRequest *)request didFailWithError:(NSError *)error - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response So my code blocks indefinetly because i am setting setUserInteractionEnabled to FALSE initially and setting it back to TRUE in the above delegates... [[[UIApplication sharedApplication]keyWindow]setUserInteractionEnabled:FALSE]; Is it possible to check the network status before creating "SKProductsRequest" or any better way to implement inApp Purchase? Thanks in advance,

  • Crash on replacing map annotations

    - by Alwin
    Solved it, see below code I'm trying to replace annotations on my MapView depending on the distance between user location and annotation. The annotations are getting replaced like they should, but when I touch te mapview my app crashes. This is de code I have so far: NSMutableArray *tempArray = [[NSMutableArray alloc] init]; for (id object in self.mapAnnotations) { if([object isKindOfClass:[ClosedAnnotation class]]) { ClosedAnnotation *ann = (ClosedAnnotation *)object; CLLocation *tempLocation = [[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance <= 1.0){ [mapView removeAnnotation:object]; OpenAnnotation *openAnnotation = [[OpenAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:openAnnotation]; [tempArray addObject:openAnnotation]; [openAnnotation release]; } else { [tempArray addObject:object]; } } else if([object isKindOfClass:[OpenAnnotation class]]){ OpenAnnotation *ann = (OpenAnnotation *)object; CLLocation *tempLocation = [[[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude] autorelease]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance > 1.0){ [mapView removeAnnotation:object]; ClosedAnnotation *closedAnnotation = [[ClosedAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:closedAnnotation]; [tempArray addObject:closedAnnotation]; [closedAnnotation release]; } else { [tempArray addObject:object]; } } } [self.mapAnnotations removeAllObjects]; [self.mapAnnotations addObjectsFromArray:tempArray]; [tempArray release]; I solved it by getting rid of the complete "two-class"-structure and handling everything within one annotation class. Works like a charm now.

  • UITableViewCell repeating problem

    - by cannyboy
    I have a UItableview with cells. Some cells have uilabels and some have uibuttons. The UIbuttons are created whenever the first character in an array is "^". However, the uibuttons repeat when i scroll down (appearing over the uilabel).. and then multiply over the uilabels when I scroll up. Any clues why? My voluminous code is below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { const NSInteger LABEL_TAG = 1001; UILabel *label; UIButton *linkButton;

  • renderInContext creating memory that is not promptly released

    - by iworkinprogress
    While debugging in instruments using 'ObjectAlloc' I'm noticing 7megs of memory being allocated for the renderInContext call, but it never is released. When I comment out the renderInContext call this doesn't happen, and future renderInContext calls does not continue to increase the memory allotment. UIGraphicsBeginImageContext(contentHolder.bounds.size); [contentHolder.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); Is there a way to force this memory to be released?

  • Any way to trigger interface orientation check?

    - by Johnny Tee
    My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!

  • Do I need to use decimal places when using floats? Is the "f" suffix necessary?

    - by Paulo Fierro
    I've seen several examples in books and around the web where they sometimes use decimal places when declaring float values even if they are whole numbers, and sometimes using an "f" suffix. Is this necessary? For example: [UIColor colorWithRed:0.8 green:0.914 blue:0.9 alpha:1.00]; How is this different from: [UIColor colorWithRed:0.8f green:0.914f blue:0.9f alpha:1.00f]; Does the trailing "f" mean anything special? Getting rid of the trailing zeros for the alpha value works too, so it becomes: [UIColor colorWithRed:0.8 green:0.914 blue:0.9 alpha:1]; So are the decimal zeros just there to remind myself and others that the value is a float? Just one of those things that has puzzled me so any clarification is welcome :)

  • UITableView and keyboard scrolling problem

    - by Jonathan
    after a lot of trial and error, I'm giving up and asking the question. I've seen a lot of people with similar problems but can't get all the answers to work right. I have a UITableView which is composed of custom cells. The cells are made of 5 text fields next to each other (sort of like a grid). When I try to scroll and edit the cells at the bottom of the UITableView, I can't manage to get my cells properly positioned above the keyboard. I have seen many answers talking about changing view sizes,etc... but none of them has worked nicely so far. Could anybody clarify the "right" way to do this with a concrete code example? Thanks in advance, Jonathan

  • merging UIImagePickerController image with cameraOverlayView

    - by GameDev
    Im really in the need for some help and advice. Spent the last week on this and have now just become frustrated as i cant get it to work! Basically, im trying to merge two images into one image to display/save. First the user picks an image from album, it goes to edit image screen where user can move and scale the image. On this screen is an overlay image (320x480) for the person to align there eyes in. Once aligned I want to save this image (edited and overlay) into one and pass the image onto my next screen. It works fine when the image is filling the edit/crop box, but when the image is widescreen with top and bottom not filling the box, then when i save the image the coords of the overlay dont get saved correctly! Heres my code, ive tried various ways of doing this but have failed at every attempt :( - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Access the cropped image from info dictionary UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"]; // Combine image with overlay before saving!! image = [self addOverlayToImage:image]; overlayGraphicView.image = nil; // Take the picture image to the post picture view controller postPictureView = [[PostPictureViewController alloc] init:image Company:companyName withLink:buyButtonLink]; [picker pushViewController:postPictureView animated:YES]; [picker release],picker = nil; } The problem is that the image picked (originalImage) could be of any height, my overlayImage is however always 320x480, its almost all transparent with just two eye images in center which i want to save over the original images eyes! - (UIImage*) addOverlayToImage:(UIImage*)originalImage { CGRect cgRect =[[UIScreen mainScreen] bounds]; CGSize size = cgRect.size; UIGraphicsBeginImageContext(size); [originalImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage* overlayImage = [UIImage imageNamed:overlayGraphicName]; [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext(); [finalImage retain]; UIGraphicsEndImageContext(); return finalImage; } I wish there was just an easy way to take a screenshot of whatever is in the edit crop box :( Please if someone could help me with this ASAP as I need to finish this in 1-2 days time! Thank you. EDIT:- I should also mention that with this I get the correct center of the screen and placement of the overlay on my next screen: [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; However, I am unable to work out the correct position of the main image especially as the height is different for every image if not fullscreen! I tried this to center it into the correct position but it doesnt work: [originalImage drawInRect:CGRectMake(0,(size.height/2 - originalImage.size.height/2), originalImage.size.width, originalImage.size.height)];

  • iPad title bars. Navbars or toolbars?

    - by Squeegy
    I see a bunch of apps for iPad with really cool title bars. These seem to be a combination of a navigation bar and a toolbar. They usually have a back button and a title as well as men other buttons. And a navbar only supports a left item, a right item and and title view. And the toolbar does not really support back buttons or titles. So how do I implement these rich navbars with many buttons on my UINavigationController driven application?

  • iOS App with OCMaps crashes when using the phone in chinese Language

    - by Pedro Morte Rolo
    I've been given the task of doing maintenance to a iOS application that uses OCMapView. I have just realized that when using the application in chinese language, it blows up when the selector doClustering is invoked on a OCMapView instance. This is for me a very puzzling behaviour, because I thought that regardless of the environment language, the OCMapView class should allways have the same methods. Am I wrong? Do you have any recomentations about how to find a solution to this problem? Thank you, Pedro
