  • Invalid argument exception - Navigation bar, tab bar, UIView.

    - by Tejaswi Yerukalapudi
    Class 1 has the following code that generates the exception - -(IBAction) searchAllAction: (id) sender { AddDiagSearchController *search = [[AddDiagSearchController alloc] initWithNibName:@"DiagSearch" bundle:nil]; [self.navigationController pushViewController:search animated:YES]; } the pushViewController part generates the following exception - 2010-04-14 14:03:31.060 Nav[10314:207] *** -[UIView addTarget:action:forControlEvents:]: unrecognized selector sent to instance 0x3956a80 And the class I'm trying to push has the following code. All the connections for IBOutlets were made through the interface builder. It's has a tableView, search text bar and a tabbar at the bottom and I'll be adding this to a UINavigationController. @interface AddDiagSearchController : UIViewController <UITableViewDataSource, UITableViewDelegate>{ UIBarButtonItem *quickAdd; UIBarButtonItem *searchAll; UITextField *searchTxt; } @property (nonatomic, retain) IBOutlet UITextField *searchTxt; -(IBAction) searchAllClicked:(id) sender; -(IBAction) quickAddClicked:(id) sender; -(IBAction) searchBtnClicked; -(IBAction) resignResponder: (id) sender; @end

  • Is is possible to derive currency symbol from currency code?

    - by Dave Hunt
    My iPhone app formats an NSDecimalNumber as a currency using setCurrencyCode, however another screen displays just the currency symbol. Rather than storing both the currency code and symbol, is it possible to derive the symbol from the code? I thought the following might work, but it just returns the symbol as $: currencyCode = [dictPrices valueForKey:@"currencyCode"]; NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease]; [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4]; [numberFormatter setCurrencyCode:currencyCode]; [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; NSString *currencySymbol = [numberFormatter currencySymbol];

  • FireBird .net provider 64bit

    - by Lavinski
    I'm trying to get a firebird web application (IIS6 64 bit) to run. However I'm getting bad image format (bit difference incompatability) issues. Has anyone got any advice to get it running. Details AnyCPU application references the .net firebird driver (through nhibernate) which uses a native 64bit dll. There is a native 32bit dll which I use for local development and it works fine. (I havn't got the 32 version working on the 64 bit server either).

  • Is it dangerous to set off an autoreleased NSOperationQueue?

    - by Paperflyer
    I have a task that takes a rather long time and should run in the background. According to the documentation, this can be done using an NSOperationQueue. However, I do not want to keep a class-global copy of the NSOperationQueue since I really only use it for that one task. Hence, I just set it to autorelease and hope that it won't get released before the task is done. It works. like this: NSInvocationOperation *theTask = [NSInvocationOperation alloc]; theTask = [theTask initWithTarget:self selector:@selector(doTask:) object:nil]; NSOperationQueue *operationQueue = [[NSOperationQueue new] autorelease]; [operationQueue addOperation:theTask]; [theTask release]; I am kind of worried, though. Is this guaranteed to work? Or might operationQueue get deallocated at some point and take theTask with it?

  • To store images from UIGetScreenImage() in NSMutable Array

    - by sujyanarayan
    Hi, I'm getting images from UIGetScreenImage() and storing directly in mutable array like:- image = [UIImage imageWithScreenContents]; [array addObject:image]; [image release]; I've set this code in timer so I cant use UIImagePNGRepresentation() to store as NSData as it reduces the performance. I want to use this array directly after sometime i.e after capturing 1000 images in 100 seconds. When I use the code below:- UIImage *im = [[UIImage alloc] init]; im = [array objectAtIndex:i]; UIImageWriteToSavedPhotosAlbum(im, nil, nil, nil); the application crashes. And I dont want to use UIImagePNG or JPGRepresentation() in timer as it reduces performance. My problem is how to use this array so that it is converted into image. If anybody has idea related to it please share with me. Thanks in Advance.

  • Issue Passing NSMutableDictionary to Method

    - by roswell
    Hello all, I'm trying some basic iPhone programming -- all has been going well but recently I've hit a bit of a roadblock. I've got a chunk of code that's passing an NSMutableDictionary (amongst other things) to a method in another class: [self.shuttle makeAPICallAndReturnResultsUsingMode:@"login" module:@"login" query:credentials]; The NSMutableArray credentials is previously defined a bit above as such: NSMutableDictionary *credentials = [[NSMutableDictionary alloc] init]; [credentials setObject:username forKey:@"username"]; [credentials setObject:password forKey:@"password"]; The method that receives it looks like such: -(id)makeAPICallAndReturnResultsUsingMode:(NSString *)mode module:(NSString *)module query:(NSMutableDictionary *)query From debugging I have determined that the code works fine up until this point within the above method: [query setObject:self.sessionID forKey:@"session_id"]; At this point, the application terminates -- the Console informs me of this exception: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSCFDictionary setObject:forKey:]: method sent to an uninitialized mutable dictionary object' This leads me to believe that I must initialize NSMutableDictionary in some way in my new method before I can access it, but I have no idea how. Any advice?

  • Unable to load detached NIB in View

    - by Sheehan Alam
    I have two NIB's ParentViewController.xib ChildViewController.xib ParentViewController.xib contains a UIView and a UIViewController. ChildViewController.xib contains a UIButton I want ChildViewController.xib to load in the ParentViewController.xib's UIView I have done the following: Created @property for UIView in ParentViewController Connected File's Owner to UIView in ParentViewController Set UIViewController in ParentViewController's NIB Name property to ChildViewController in Interface Builder Set ChildViewController view property to UIView in ParentViewController I was hoping this would load ChildViewController into my UIView in ParentViewController but no luck. I did get the following warning, which could be the culprit: 'View Controller (Child View)' has both its 'NIB Name' property set and its 'view' outlet connected. This configuration is not supported. I also have added additional code in ParentViewController's viewDidLoad(): - (void)viewDidLoad { [super viewDidLoad]; ChildViewController *childViewController = [[ChildViewController alloc]initWithNibName:@"ChildViewController" bundle:nil]; childViewController.view = self.myView; } Any thoughts on why ChildViewController does not load in the UIView of ParentViewController?

  • 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]; }

  • How do I Call a method from other Class

    - by balexandre
    Hi guys, I'm having some trouble figuring out to call methods that I have in other classes #import "myNewClass.h" #import "MainViewController.h" @implementation MainViewController @synthesize txtUsername; @synthesize txtPassword; @synthesize lblUserMessage; - (IBAction)calculateSecret { NSString *usec = [self calculateSecretForUser:txtUsername.text withPassword:txtPassword.text]; [lblUserMessage setText:usec]; [usec release]; } ... myNewClass.h #import <Foundation/Foundation.h> @interface myNewClass : NSObject { } - (NSString*)CalculateSecretForUser:(NSString *)user withPassword:(NSString *)pwd; @end myNewClass.m #import "myNewClass.h" @implementation myNewClass - (NSString*)CalculateSecretForUser:(NSString *)user withPassword:(NSString *)pwd { NSString *a = [[NSString alloc] initWithFormat:@"%@ -> %@", user, pwd]; return a; } @end the method CalculateSecretForUser always says 'MainViewController' may not respond to '-calculateSecretForUser:withPassword:' what am I doing wrong here?

  • Show UIAlertView that is same as UIRemoteNotification when app is running in foreground

    - by Sidwyn Koh
    I understand that we can handle push notifications via the method: - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo and we can check if the app was running in the foreground: if (application.applicationState == UIApplicationStateActive ) { ... } How do we show the exact same notification with localisation? NSString *message = [[[userInfo valueForKey:@"aps"] valueForKey:@"alert"] valueForKey:@"loc-key"]; NSString *trueMessage = NSLocalizedString(message, nil); UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Alert" message:trueMessage cancelButtonItem:@"OK" otherButtonItems:@"Show", nil]; [alertView show]; This shows the raw unlocalized text, e.g. "You have a new alert from %1@ on %2@." My question is, how can we place the loc-args inside the UIAlertView as well, when the app is running in the foreground?

  • JBoss Seam - order event listeners

    - by Walter White
    Hi all, I would like to order my event listeners. Is it possible to do this in JBoss Seam 2.x? I am thinking as a workaround, which is quite simple, I will just daisy chain my events: fire event A. do something on event A. a. fire event B do something on event B. Any comments with this design? Is this a good / bad practice? Thanks, Walter

  • iPhone: UITableView Becomes Invisible after Changing the Data it Displays

    - by Alexander Shemshurenko
    Hi I have application with a TabBar that controls several views. In one view, I control connections to different servers. Each server provides a different set of items. I display these items in UITableView on another view. The problem is that the tableview displays OK the first time but if I go back to view number one and change the server, thereby changing the list of items that should be displayed in tableview, the tableview becomes invisible for some reason. If I tap on the screen in the place where it should be, it becomes visible again. I create table view like this UITableView * aTableView = [[UITableView alloc] initWithFrame:CGRectMake(X,Y,Width,Height) style:UITableViewStyleGrouped]; [[self view] addSubview:aTableView]; aTableView.dataSource = self; Ive tried to call reloadData and setNeedsDisplay in viewWillAppear of the UIViewController that hosts this tableview but without success. Any advice? Thanks

  • How do I find out what objects points to another object i Xcode Instruments

    - by Arlaharen
    I am trying to analyze some code of mine, looking for memory leaks. My problem is that some of my objects are leaking (at least as far as I can see), but the Leaks tool doesn't detect the leaks. My guess is that some iPhone OS object still holds pointers to my leaked objects. The objects I am talking about are subclasses of UIViewController that I use like this: MyController *controller = [[MyController alloc] initWithNibName:@"MyController" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; When these objects are no longer needed I do: [self.navigationController popViewControllerAnimated:YES]; Without a [controller release] call right now. Now when I look at what objects that gets created I see a lot of MyController instances that never gets destroyed. To me these are memory leaks, but to the Leaks tool they are not. Can someone here tell me if there is some way Instruments can tell me what objects are pointing to my MyController instances and thereby making them not count as memory leaks?

  • Why my own UIViewController can't detect touch?

    - by Tattat
    I have my OwnViewController, the viewDidLoad is like this: - (void)viewDidLoad { [super viewDidLoad]; UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImg" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; self.view = imageView; CGImageRelease(imageRef); } It works, and I have detect touches method like this: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesBegan"); } But my UIView can't detect any touches. My Own UIViewController is a subclass of UIViewController. It is a little square view on the IB, why that can't detect touches? thx u.

  • get the time offset from GMT from latitude longitude

    - by ravun
    Is there a way to estimate the offset from GMT (or time zone) from a latitude/longitude? I've seen geonames, but this would need to work long term and we don't really want to rely on a web service. It'd just be used for determining whether to display "today" or "tonight" when giving information to various users so it wouldn't need to be too accurate (an hour or two off wouldn't be bad).

  • UISearchBar animation hidding button

    - by David Carvalho
    Hello I currently have a UISearchBar (attached to a UISearchDisplayController), but I reduced the width of the search bar so I could display a custom button to its right when the search bar is not selected. The button is used to access other views. However, when I select the search bar and then press cancel (or even perform a search) and return to the normal view, where the search bar should be displayed with my custom button, the search bar animates and takes up all the room for the button and the is not displayed. Essentially, the search bar takes up all the width of the screen when I only want it to take up a part of it. Is there any way to prevent the search bar from animating to the whole width of the screen? This is how I defined the CGRect of the search bar: self = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 250.0f, 45.0f)] Any help would be great. Regards

  • How to access pixels of an NSBitmapImageRep?

    - by Paperflyer
    I have an NSBitmapImageRep that is created like this: NSBitmapImageRep *imageRep = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:waveformSize.width pixelsHigh:waveformSize.height bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:YES colorSpaceName:NSCalibratedRGBColorSpace bytesPerRow:0 bitsPerPixel:0]; Now I want to access the pixel data so I get a pointer to the pixel planes using unsigned char *bitmapData; [imageRep getBitmapDataPlanes:&bitmapData]; According to the Documentation this returns a C array of five character pointers. But how can it do that? since the type of the argument is unsigned char **, it can only return an array of chars, but not an array of char pointers. So, this leaves me wondering how to access the individual pixels. Do you have an idea how to do that? (I know there is the method – setColor:atX:y:, but it seems to be pretty slow if invoked for every single pixel of a big bitmap.)

  • iPhone Development: Get images from RSS feed

    - by Matthew Saeger
    I am using the NSXMLParser to get new RSS stories from a feed and am displaying them in a UITableView. However now I want to take ONLY the images, and display them in a UIScrollView/UIImageView (3 images side-by side). I am completely lost. I am using the following code to obtain 1 image from a URL. NSURL *theUrl1=[NSURL URLWithString:@"http://farm3.static.flickr.com/2586/4072164719_0fa5695f59.jpg"]; JImage *photoImage1=[[JImage alloc] init]; [photoImage1 setContentMode:UIViewContentModeScaleAspectFill]; [photoImage1 setFrame:CGRectMake(0, 0, 320, 170)]; [photoImage1 initWithImageAtURL:theUrl1]; [imageView1 addSubview:photoImage1]; [photoImage1 release]; This is all I have accomplished, and it works, for one image, and I have to specify the exact URL. What would you recommend I do to accomplish this?
