  • sqlite3 DELETE problem "Library Routine Called Out Of Sequence"

    - by Michael Bordelon
    Here is my second stupid Noob problem. I am trying to do a simple Delete and I keep blowing up on the prepare step. I already have other Deletes, Inserts, Updates and Selects working. I am sure it is something simple. I appreciate your help. + (void)flushTodaysWorkouts { sqlite3_stmt *statement = nil; //open the database if (sqlite3_open([[BIUtility getDBPath] UTF8String], &database) != SQLITE_OK) { sqlite3_close(database); NSAssert(0, @"Failed to opendatabase"); } NSArray *woList = [self todaysScheduledWorkouts]; for (Workout *wo in woList) { NSInteger woID = wo.woInstanceID; if(statement == nil) { const char *sql = "DELETE FROM IWORKOUT WHERE WOINSTANCEID = ?"; if(sqlite3_prepare_v2(database, sql, -1, &statement, NULL) != SQLITE_OK) NSAssert1(0, @"Error while creating delete statement.

  • Issues using UITapGestureRecognizers in Interface Builder

    - by 5StringRyan
    I'm attempting to use the UITapGestureRecognizer object that can be found in Interface Builder. I've dragged a single "UITapGestureRecognizer" from the object library to a single view xib. I then create an IBAction method from this tap gesture, for a simple test, I'm just printing an "NSLog" message to the console once there is a tap on the view. I've run this, and the tap method isn't being called. I right click the view in IB and I noticed that there is a warning "!" on the view's "Outlook Collections" I see: Outlook Collections gestureRecognizers - Tap Gesture Recognizer (!) The warning states: UIView does not have an outlet collection named gestureRecognizers. What do I need to do to remedy this?

  • Disable ARC with Xcode 5

    - by user2187565
    First, sorry for my bad english, I'm french and had 15years old but StackOverFlow is for me the best forum for developers. So, in the previous versions of Xcode, we can disable ARC (Automatic Reference Counting) in the project settings when we create the project. Not now with Xcode 5 and ARC to pose me a problem: with an property list file, for the reading step, Xcode send me an error: "implicit conversion of 'int' to 'id' is disallowed with ARC". I had not the problem with the same code with Xcode 4. In my property list file, The keys are numbers and also in my viewController.m . NIKOS M.: No problem, but I don't see how I can add compiler flag with the 5th version of Xcode. The code (with french string...): NSString *error; NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *plistPath = [rootPath stringByAppendingPathComponent:@"Save.plist"]; NSArray *keys = [NSArray arrayWithObjects:@"valeurCompteur1", @"valeurCompteur2", @"valeurCompteur3", @"valeurCompteur4", @"valeurCompteur5", @"nomCompteur1", @"nomCompteur2", @"nomCompteur3", @"nomCompteur4", @"nomCompteur5", nil]; NSArray *objs = [NSArray arrayWithObjects: compteur1, compteur2, compteur3, compteur4, compteur5, nameC1, nameC2, nameC3, nameC4, nameC5, nil]; REVIEW: When I disallow ARC for the target, an warning persist. How I can resolve that please ? Thank you very much.

  • Drill down rss reader iphone

    - by bing
    Hi everyone, I have made a simple rss reader. The app loads an xml atom file in an array.

  • How do I convert a NSString into TIS-620 encoded string

    - by MacPC
    In the apple document, I can see that there's a way to convert from UTF8 string to ASCII string like this NSData *asciiData = [theString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:NSASCIIStringEncoding]; But my app requires a TIS-620 string to post to a site so I try to do the same thing NSData *asciiData = [newPost.header dataUsingEncoding:kCFStringEncodingMacThai allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:kCFStringEncodingMacThai]; NSLog(@"%@", asciiString); The output I got is like this ???????????. Does anyone know how to convert the NSString to TIS-620 properly? Thanks so much.

  • NSTableView - Trying to fit exactly 9 rows

    - by Justin808
    Hi, I'm trying to size the rows of a NSTableView to exactly 9 rows fit. I've tried [menuTableView setRowHeight:floor(menuRect.size.height / 9)]; and I've tried [menuTableView setRowHeight:(menuRect.size.height / 9)]; and [menuTableView setRowHeight:ceil(menuRect.size.height / 9)]; but all of them have the same issue, if I've selected row 0 then row 9 is clipped at the bottom and if I select row 9 then row 0 is clipped at the top. How can I set up a NSTableView to show 9 full rows so no matter what there is never a partial row visible? Thanks, edit: Yes menuRect is the frame for the menuTableView

  • self.window.rootViewController vs window addSubview

    - by Gazzer
    I've noticed a lot of examples for iPhone apps in the Application Delegate - (void)applicationDidFinishLaunching:(UIApplication *)application have [window addSubview: someController.view]; (1) as opposed to self.window.rootViewController = self.someController; (2) Is there any practical reason to use one over the other? Is one technically correct? Do controller's have the an equivalent command to number (2) like self.someController.rootController = self.someOtherController; // pseudocode

  • Recursively listing, and storing, directory contents

    - by enchilada
    I know how to recursively list directory contents. I will be using Snow Leopard's enumeratorAtURL:includingPropertiesForKeys:options:errorHandler: method to do this. However I want to store my findings into a object hierarchy (of, say, objects of a custom FileOrDirectory class that has isLeaf, children, and count attributes). I need to pre-load the directory and file structure into such a object hierarchy, in order to do whatever I want with NSTreeController and whatnot. I guess the trickiest thing here is to get the children attribute correct in the object hierarchy. Any ideas?

  • How do I remove a button from a view controller's toolbar on the iPhone?

    - by Tony
    I have code that works great for adding a button to the toolbar: NSArray* toolbarItems = [NSArray arrayWithObjects:flexibleSpace,shuffleBarItem,flexibleSpace,nil]; self.toolbarItems = toolbarItems; However, I also want to be able to remove toolbar items. When I use the below method, my application crashes: NSArray* toolbarItems = [NSArray arrayWithObjects:flexibleSpace,nil]; self.toolbarItems = toolbarItems; Does anyone know how I can dynamically alter the toolbar on the iPhone? Thanks!

  • NSView -(void)keyDown in console program

    - by Jonas Byström
    I'm not getting the -(void)keyDown callback on my inherited NSOpenGLView (note that mouseMoved does not work either though I do setAcceptsMouseMovedEvents:YES, but that is not an issue yet). It implements - (BOOL)acceptsFirstResponder { return YES; } but still no luck. My knowledgeable friend implied that it might have something to do with that the application is still a console application and not a bundled .app (I'm currently porting it). If so: is there some way to circumvent? Could the cause be something else? When I terminate my console application, I frequently see all my keypresses go to stdout so it does seem reasonable...

  • editButtonItem set but no minus buttons?

    - by QAD
    My edit button is placed in viewDidLoad: self.navigationItem.rightBarButtonItem = self.editButtonItem; It shows up correctly on the nav bar, and tapping this button indeed change it to Done. However, no minus buttons show up in my table rows. Swiping a row, then tap Delete works, though. Any ideas? EDIT 1: Here's how I'm doing: - (void)loadView { tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; tableView.delegate = self; tableView.dataSource = self; tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; self.view = tableView; } EDIT 2: My observation is that the edit and minus buttons display fine if my tableview is created in IB (RootViewController). The other two (or three) tableview are created by the aforemention code, so that might be the problem. Guess I'd have to dive in to isEditing, editing and whatnot.

  • My UITableView has duplicated rows

    - by Mark
    Im not sure why, but my UITableView, which isnt anything fancy, is showing repeating rows when it shouldnt be. It seems that the rows that get added when the user scrolls (i.e. the rows that are off the screen to start with) are getting the data for the wrong row index. Its almost like when a new cell is de-queued, it's using a cell that 'was' used, but wasn't cleaned up correctly. Do you need to 'clean up' cells that are de-queue so that new cells dont use cells that are already created? my code is as below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CustomCellIdentifier = @"CustomCellIdentifier"; MyDayCell *cell = (MyDayCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[MyDayCell class]]) cell = (MyDayCell *)oneObject; } NSUInteger section = [indexPath section]; NSUInteger row = [indexPath row]; NSArray *thisSectionItems = (NSArray*)[self.listData objectForKey: [[NSNumber alloc] initWithInt:section]]; MyDayDetails *rowData = [thisSectionItems objectAtIndex:row]; //setup my cells data here... return cell; } Is there anything wrong with this code? has anyone seen anything like this before?

  • runModalForWindow throttles http requests

    - by Nikita Rybak
    I have url connection, which normally works fine NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:delegate]; But when I create a modal window, no request ever receives response: [NSApp runModalForWindow:window]; If I comment this line out, thus creating a 'standard' window, everything works. I tried implementing all methods from NSURLConnectionDelegate, not a single of them called. I suspect this is something about 'run loops', but have little experience in this area. Does anybody have experience in this? Thank you

  • Setting synthesized arrays causing memory leaks using nested arrays

    - by webtoad
    Hello: Why is the following code causing a memory leak in an iPhone App? All of the initted objects below leak, including the arrays, the strings and the numbers. So, I'm thinking it has something to do with the the synthesized array property not releasing the object when I set the property again on the second and subsequent time this piece of code is called. Here is the code: "controller" (below) is my custom view controller class, which I have a reference to, and I am setting with this code snippet: sqlite3_stmt *statement; NSMutableArray *foo_IDs = [[NSMutableArray alloc] init]; NSMutableArray *foo_Names = [[NSMutableArray alloc] init]; NSMutableArray *foo_IDsBySection = [[NSMutableArray alloc] init]; NSMutableArray *foo_NamesBySection = [[NSMutableArray alloc] init]; // Get data: NSString *sql = @"select distinct p.foo_ID, p.foo_Name from foo as p "; if (sqlite3_prepare_v2(...) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { int p_id; NSString *foo_Name; p_id = sqlite3_column_int(statement, 0); char *str2 = (char *)sqlite3_column_text(statement, 1); foo_Name = [NSString stringWithCString:str2]; [foo_IDs addObject:[NSNumber numberWithInt:p_id]]; [foo_Names addObject:foo_Name]; } sqlite3_finalize(statement); } // Pass the array itself into another array: // (normally there is more than one array in each array) [foo_IDsBySection addObject: foo_IDs]; [foo_NamesBySection addObject: foo_Names]; [foo_IDs release]; [foo_Names release]; // Set some synthesized properties (of type NSArray, nonatomic, // retain) in controller: controller.foo_IDsBySection = foo_IDsBySection; controller.foo_NamesBySection = foo_NamesBySection; [foo_IDsBySection release]; [foo_NamesBySection release]; Thanks for any help!

  • NSColor, 10.6 and Gamma 2.2

    - by Stephen Blinkhorn
    With Snow Leopard the default gamma changed from 1.8 to 2.2. I happen to be working on a few Mac apps that use a very dark custom colour scheme provided by Cocoa. On 10.5 it looks fine but on 10.6 with the new gamma it's much darker and really hard on the eyes. The colour scheme is defined using numerous [NSColor colorWithCalibratedRed:green:blue:alpha:] objects within a theme class. Is there any way to 'convert' an NSColor object so that it displays on 10.6 exactly as it would on 10.5 with the old 1.8 gamma? I know this can be achieved globally from within System Preferences but that's not what I'm after.

  • Any good way to set the exit status of a Cocoa application?

    - by buglesareking
    I have a Cocoa app which interacts with a server and displays a GUI. If there is a fatal error, I display an alert and exit. I'd like to set the exit status to a non-zero value to reflect that an error occurred, for ease of interaction with some other UNIX based tools. Unfortunately I've been unable to find a good way to do so - NSApplication doesn't seem to have any way to set an exit status. At the moment, I've subclassed NSApplication and added an exitStatus ivar (which I set in my app delegate when necessary), then overridden -terminate: so that it calls exit(exitStatus). This works fine, but it seems a bit grungy to me, not to mention that I may be missing something important that the stadnard `terminate: is doing behind the scenes. I can't call [super terminate:sender] in my subclassed method, because that exit()s without giving me a chance to set the status. Am I missing something obvious?

  • How to call another class's method from my app delegate

    - by Jared
    I have an application that utilizes UILocalNotifications to pop-up UIAlertViews. When the notification fires, the user chooses to go into the app, and this method is called from my app delegate: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {...} Where I can handle it and where I also prompt another alertview for more information. So when the app launches, it is displaying view A, and then the alertview pops up and prompts for input. This alertview, however, is originating from my app delegate. I need to be able to reload view A when the user hits Yes/No on the alertview. How can I do that from within my app delegate? Any help is appreciated!!

  • How does Mach-O loader loads different NSString objects?

    - by overboming
    I have known that If you define a bunch of @"" NSString objects in the source code in Mac OS. These NSStrings will be stored in a segment in the Mach-O library. Section sectname __ustring segname __TEXT addr 0x000b3b54 size 0x000001b7 offset 731988 align 2^1 (2) reloff 0 nreloc 0 flags 0x00000000 reserved1 0 reserved2 0 If I hex dump the binary, they are aligned closely one by one with a 0x0000as separator. What I want to know is how does the loader in Mac OS X load these NSStrings when the program runs? Are they loaded simpily by recognize the 0x0000 separator or these is a string offset table elsewhere in the binary pointing to separate NSString objects? Thanks. (What I really want to do is the increase the length of one of the NSString, so I have to know how the loader recognize these separate objects)
