  • Core Location question....

    - by Moshe
    This tutorial on mobileorchard.com uses 2 classes (or 2 sets of .h and .m) to implement core location. Can I just use everything there in my existing class? How would I do that? Also, is the - (id) init { self = [super init]; if (self != nil) { self.locationManager = [[[CLLocationManager alloc] init] autorelease]; self.locationManager.delegate = self; // send loc updates to myself } return self; } method the same as the usual initWithNib? I;m trying to quickly implement something based on location information. As much help describing the above linked tutorial would be helpful. Thanks. No - really, Thank You.

  • UIImage from NSDocumentDirectory leaking memory

    - by Emil
    Hey. I currently have this code: UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@.png", [postsArrayID objectAtIndex:indexPath.row]]]]; It's loading in an image to set in a UITableViewCell. This obviously leaks a lot of memory (I do release it, two lines down after setting the cells image to be that image), and I'm not sure if it caches the image at all. Is there another way, that doesen't leak so much, I can use to load in images multiple times, like in a tableView, from the Documents-directory of my app? Thanks.

  • Application crash when using an NSTimer and pushViewController

    - by Cesar
    I'm using an NSTimer to implement a 3 seconds splash screen. If a don't use a timer the view it's correctly pushed but if I use the timer for adding a little delay the application crash with a EXC_BAD_ACCESS. I'm pretty sure the answer contains "memory management" but I can't get the point... @interface RootViewController : UIViewController { NSTimer *timer; } -(void)changeView:(NSTimer*)theTimer; @property(nonatomic,retain) NSTimer *timer; ... @implementation RootViewController @synthesize timer; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [[self navigationController] setNavigationBarHidden:YES]; timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(changeView:) userInfo:nil repeats:NO]; } -(void)changeView:(NSTimer*)theTimer { NSLog(@"timer fired"); //Crash here, but only if called using a timer [[self navigationController] pushViewController:list animated:YES]; }

  • How to change rowHeight of a TableViewCell depending on Stringlength

    - by Jens Koehler
    I have a table with different entries, each with different length. The height of each row should fit, so it can show the whole string. I use the following code: //... cellForRowAtIndexPath if (row == 0) { cell = [tableView dequeueReusableCellWithIdentifier:@"affCell"]; //if (!cell) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"affCell"]autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.autoresizingMask = UIViewAutoresizingFlexibleHeight; affL = [[UILabel alloc] initWithFrame:CGRectZero]; affL.textAlignment = UITextAlignmentLeft; affL.autoresizingMask = UIViewAutoresizingFlexibleHeight; [cell.contentView addSubview:affL]; //} //declaration label affL.text = [fDictionary objectForKey:@"aff"]; affL.numberOfLines = 0; [affL sizeToFit]; affL.frame = CGRectMake(15.0, 10.0, 220.0, affL.frame.size.height); CGFloat affLH = affL.frame.size.height; [tableView setRowHeight:affLH+30]; I also use //... heightForRowAtIndexPath return affL.frame.size.height; How can I fix this problem?

  • Custom UITableViewCell changing indexPath While Scrolling ?

    - by Chris
    I have a custom UITableViewCell which I created in Interface Builder. I am successfully Dequeuing cells, but as I scroll, the cells appear to begin calling different indexPaths. In this example, I am feeding the current indexPath.section and indexPath.row into the customCellLabel. As I scroll the table up and down, some of the cells will change. The numbers can be all over the place, but the cells are not skipping around visually. If I comment out the if(cell==nil), then the problem goes away. If I use a standard cell, the problem goes away. Ideas why this might be happening? // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:@"CalendarEventCell"]; if (cell == nil) { NSLog(@"Creating New Cell !!!!!"); NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CalendarEventCell" owner:self options:nil]; cell = (UITableViewCell *)[nib objectAtIndex:0]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } // Set up the cell... [customCellLabel setText:[NSString stringWithFormat:@"%d - %d",indexPath.section, indexPath.row]]; return cell; }

  • Navigation Controller Views in Landscape

    - by Mahadevan S
    Hi, I have set up a navigation controller ( navController ) in Portrait mode to which I push all the viewcontrollers I have. Now when a user switches to Landscape mode, I need to display all the views as a coverflow. For this I use [navController viewControllers] to get all the view controllers in the stack. In the Landscape view controller NSArray * arr = [navController viewControllers]; self.view = [arr objectAtIndex:0]; [arr objectAtIndex:0]; returns the correct view ( the bottombost viewcontroller's view in the nav stack ). My problem is these views never get displayed ie the views extracted from the navController never gets displayed. If i try to create a new view and insert all the subviews of a view, it gets displayed. eg : UIView * newView = [[UIView alloc] init]; for (UIView *subView in [arr objectAtIndex:0]) [newView addSubView:subView]; self.view = newView; The above piece of code works. But simply adding the view doesnt seem to work.. Can anyone explain the solution? Many thanks

  • OAuth secrets in mobile apps

    - by Felixyz
    When using the OAuth protocol, you need a secret string obtained from the service you want to delegate to. If you are doing this in a web app, you can simply store the secret in your data base or on the file system, but what is the best way to handle it in a mobile app (or a desktop app for that matter)? Storing the string in the app is obviously not good, as someone could easily find it and abuse it. Another approach would be to store it on you server, and have the app fetch it on every run, never storing it on the phone. This is almost as bad, because you have to include the URL in the app. I don't believe using https is any help. The only workable solution I can come up with is to first obtain the Access Token as normal (preferably using a web view inside the app), and then route all further communication through our server, where a script would append the secret to the request data and communicates with the provider. Then again, I'm a security noob, so I'd really like to hear some knowledgeable peoples' opinions on this. It doesn't seem to me that most apps are going to these lengths to guarantee security (for example, Facebook Connect seems to assume that you put the secret into a string right in your app). Another thing: I don't believe the secret is involved in initially requesting the Access Token, so that could be done without involving our own server. Am I correct?

  • applicationWillTerminate Appears to be Inconsistent

    - by Lauren Quantrell
    This one has me batty. In applicationWillTerminate I am doing two things: saving some settings to the app settings plist file and updating any changed data to the SQLite database referenced in the managedObjectContext. Problem is it works sometimes and not others. Same issue in the simulator and on the device. If I hit the home button while the app is running, I can only sometimes get the data to store in the plist and into the CoreData store. It seems that it's both works or neither works, and it makes no difference if I switch the execution order (saveState, managedObjectContext or managedObjectContext, saveState). I can't figure out how this can happen. Any help is greatly appreciated. lq AppDelegate.m @synthesize rootViewController; - (void)applicationWillTerminate:(UIApplication *)application { [rootViewController saveState]; NSError *error; if (managedObjectContext != nil) { if ([managedObjectContext hasChanges] && ![managedObjectContext save:&error]) { // Handle error exit(-1); // Fail } } } RootViewController.m - (void)saveState { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:self.someInteger forKey:kSomeNumber]; [userDefaults setObject:self.someArray forKey:kSomeArray]; }

  • Add double tap action (presentModalViewController) to UISCOLLVIEW

    - by R.J.
    I have been wrestling this issue for a while now and cannot seem to get the following "touchesEnded" method to execute within a UISCROLLVIEW. I have read on many of the forums that UISCROLLVIEW will take control of all touch events unless it is subclassed, but I cannot seem to get the code right (still new to the SDK). Basically I have a scrollview made uo with several UIIMAGEVIEW's and currenlty have scrolling with paging (much like the photo app). I have been studying the SCROLLING MADDNESS example without success. All I want to do is anywhere in the UISCROLLVIEW have the user double tap to presentModalViewController back to my info page (i.e.) (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSSet *allTouches = [event allTouches]; switch ([allTouches count]) { case 1: {// One finger touch UITouch *touch = [[allTouches allObjects] objectAtIndex:0]; if ([touch tapCount] == 2) {InfoButtonViewController *scroll = [[InfoButtonViewController alloc] initWithNibName:nil bundle:nil]; scroll.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:scroll animated:YES]; [scroll release]; } } } } Any code assistance would be greatly appreciated. The UISCROLLVIEW is implemented as follows (let me know if I need to provide additional details). Thank you in advance... MyViewController.h @interface MyViewController : UIViewController { } @end

  • How i print the text using CGContextSetTextPosition?

    - by Rajendra Bhole
    hi, i write an application in which i want to write/draw the text using CGContext functions such as CGContextSetTextPosition, CGContextSetTextDrawingMode, etc. I written an code but it can't be work, CGContextSetTextDrawingMode (ctx , kCGTextFillStroke); CGContextSetRGBFillColor(ctx, 5.0, 5.0, 5.0, 1.0); CGContextSelectFont(ctx, "Times", 10, kCGEncodingMacRoman); CGContextShowTextAtPoint (ctx, 60.0, 426.0, (const char*)"Sat", (size_t)20); The above code is appropriate or not?

  • indentationLevelForRowAtIndexPath not indenting custom cell

    - by Xetius
    I have overridden the tableView:indentationLevelForRowAtIndexPath method in my UITableViewController derived class as follows: - (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath { NSDictionary* item = [self.projects objectAtIndex:indexPath.row]; int indentationLevel = [[item objectForKey:@"indent"] intValue]; DLog (@"Indentation Level for Row %d : %d", indexPath.row, indentationLevel); return indentationLevel; } I initially thought that this was not being called but that was operator error (err, mine) and I hadn't defined the symbol DEBUG=1. However, it is being called (duh me!) and this is the log output: -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 0 : 1 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 1 : 1 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 2 : 2 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 3 : 2 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 4 : 2 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 5 : 1 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 6 : 2 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 7 : 2 -[RootViewController tableView:indentationLevelForRowAtIndexPath:] [Line 129] Indentation Level for Row 8 : 1 But, this is not affecting the layout of the cells. No indentation. This is my itemCellForRowAtIndexPath implementation, if that makes any difference: -(UITableViewCell*)tableView:(UITableView *)tableView itemCellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString* cellIdentifier = @"projectItemCell"; ProjectItemTableViewCell* cell = (ProjectItemTableViewCell*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { NSArray* nib = [[NSBundle mainBundle] loadNibNamed:@"ProjectItemTableViewCell" owner:self options:nil]; for (id oneObject in nib) { if ([oneObject isKindOfClass:[ProjectItemTableViewCell class]]) { cell = (ProjectItemTableViewCell*)oneObject; } } } NSDictionary* item = [self.projects objectAtIndex:indexPath.row]; cell.projectDescLabel.text = [item objectForKey:@"name"]; cell.itemCountlabel.text = [NSString stringWithFormat:@"%d", [[item objectForKey:@"cache_count"] intValue]]; cell.itemCountlabel.backgroundColor = [UIColor colorForHex:[item objectForKey:@"color"]]; cell.indentationWidth = 20; return cell; } How do I indent a custom UITableViewCell which I have defined in Interface Builder? If I change the itemCellForRowAtIndexPath to use a default UITableViewCell with the code below, then it indents fine. static NSString* cellIdentifier = @"projectItemCell"; UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease]; } NSDictionary* item = [self.projects objectAtIndex:indexPath.row]; cell.textLabel.text = [item objectForKey:@"name"]; cell.indentationWidth = 40; return cell;

  • PerformSelectorInBackground leaking on device

    - by Oysio
    While it seems to not pose a problem on the simulator, using performSelectorInBackground on the device causes memory leaks. Or at least that's what Instruments indicates. Looking at the code I don't have a single clue what the cause could be. I tried to strip the affected code to a bare minimum but still strangely Instruments keeps showing a leak every time this piece of code is executed. Anything unusual going on here? //In viewcontrollerA: -(void)mainLoop { [self.viewControllerB performSelectorInBackground:@selector(calculateTotals) withObject:nil]; //This gives the same problem //[NSThread detachNewThreadSelector:@selector(calculateTotals) toTarget:self.viewControllerB withObject:nil]; //UI stuff ... } //viewControllerB: -(void)calculateTotals { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; //Heavy calculations ... [pool release]; }

  • MKReverseGeocoder delegate location?

    - by fuzzygoat
    I have a quick question regarding memory management that I am not quite sure about. I currently have a locationManager delegate that calls locationManager:didUpdateToLocation:fromLocation when it resolves the device location. My question is I am looking at adding ReverseGeoCoding after I have obtained the [newLocation coordinate] but am unsure about doing the alloc here, as each time locationManager:didUpdateToLocation:fromLocation gets called I will be alloc-ing a new MKReverseGeoCoder? // LOCATION -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // GeoCoding: MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:[newLocation coordinate]]; [geoCoder setDelegate:self]; [geoCoder start]; [self foundLocation]; } Can anyone point me in the right direction with regards to this? I did try doing the alloc in application:didFinishLaunchingWithOptions: but then realised I did not have access to [newLocation coordinate]. many thanks gary

  • Is there a difference between only <NSXMLParserDelegate>, only setDelegate method, or the use of bot

    - by gotye
    Hey, I noticed that when I do this : [myParser setDelegate:self]; it works :D (even if I didn't add the code in the header file ... you know, the <delegateStuff, delegateOtherStuff> in the interface declaration) When are you supposed to modify the header file to make your delegate work ? Is the setDelegate method enough to make it work ? Cheers for any help ;) Gauthier

  • Show blank UITableViewCells in custom UITableView

    - by Typeoneerror
    I am trying to customize a UITableView. So far, it looks good. But when I use a custom UITableViewCell sub-class, I do not get the blank table cells when there's only 3 cells: Using the default TableView style I can get the repeating blank rows to fill the view (for example, the mail application has this). I tried to set a backgroundColor pattern on the UITableView to the same tile background: UIColor *color = [UIColor colorWithPatternImage:[UIImage imageNamed:@"score-cell-bg.png"]]; moneyTableView.backgroundColor = color; ...but the tile starts a bit before the TableView's top, so the tile is off once the actual cell's are done displaying: How can I customize my tableview but still keep the blank rows if there's less rows than fill a page?

  • Problem with Xcode organizer screen capture

    I'm currently running Xcode 3.2.2 on Snow Leopard. When opening Organizer Screenshots I see a list of screenshots I did before. But when I click the Capture button, nothing's happening. I don't see any messages popping up or any errors from the Console tab. I also tried restoring the iPod Touch (2nd gen) but that didn't help. Any thoughts? Thanks!

  • OpenGL ES clarifying question regarding FBOs -- sorry can't find this info anywhere else?

    - by DevDevDev
    If I instantiate an FBO without binding a rendering buffer or a texture to it, what happens when I draw to it, nothing? Do I need to associate a rendering target (renderbuffer or texture) to have an FBO do anything? What I'm trying to do is precache some buffers and then merge them later, but that doesn't seem to work at all. Ideally I'd like to do something like glBindFramebufferOES(GL_FRAMEBUFFER_OES, fbo1); // Draw some stuff to fbo1 glBindFramebufferOES(GL_FRAMEBUFFER_OES, fbo2); // Draw some stuff to fbo2 // ... // ... // glRenderFbo(fbo1); -- Not a func // Set blending, etc. etc. // glRenderFbo(fbo2); -- Not a func
