  • Can not read and save a number from/into an .plist

    - by Flocked
    Hello, I created a property list with the name propertys.plist. Then I wrote this: NSString *path = [[NSBundle mainBundle] bundlePath]; NSString *finalPath = [path stringByAppendingPathComponent:@"speicherung.plist"]; NSMutableArray *plistData = [[NSMutableArray arrayWithContentsOfFile:finalPath] retain]; int a = [plistData objectAtIndex:1]; NSLog(@"%i", a); // returns 41386032, but the right number is 0 a = a + 1; NSNumber *ff = [NSNumber numberWithInt:a]; [plistData insertObject:ff atIndex:1]; NSLog(@"%@", [plistData objectAtIndex:1]); // returns 41386033 [plistData writeToFile:finalPath atomically:YES]; My app always get the wrong number. Why?

  • Add UITabBar Control!

    - by Taimur Hamza
    hi, I m stuck in a really simple problem. And i m afraid my question might annoy some people. The problem i am facing in short is that i want to add UITabBar Control to my iphone application other than the main screen. Let me explain, I have done everything successfully Added UItabbar control from IB in the main window's xib, added a variable at the back end , associated it by dragging the line. Also added a UIWindow variable and wrote these lines . [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; when i launch the application a blank window appears and tab bar shows on its bottom. But the problem i dont want to add it to a particular window which is inside my app. Its no the first screen of my app. Its actually the 3rd screen of my app. Can anybody help ? thanks Taimur

  • Detecting iPhone camera orientation

    - by Stephen Petschulat
    I'm getting inconsistent results depending on whether I get the image directly from the camera in the callback or choosing it from the camera roll. In the UIImagePickerControllerDelegate callback method, the UIImage.imageOrientation comes up as UIImageOrientationRight no matter how the photo is taken. When reading it off the Camera Roll, a landscape shot (turned left) comes up UIImageOrientationUp while a portrait shot comes up UIImageOrientationRight. How can I reliably get the camera orientation in both situations?

  • How can I pass latitude and longitude values from UIViewController to MKMapView?

    - by jerincbus
    I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.mapAddress = self.address; mapController.mapTitle = self.Title; mapController.mapLat = self.lat; mapController.mapLng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; //mapController = nil; } And on my MapViewController.h file I have: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import "DetailViewController.h" #import "CourseAnnotation.h" @class CourseAnnotation; @interface MapViewController : UIViewController <MKMapViewDelegate> { IBOutlet MKMapView *mapView; NSString *mapAddress; NSString *mapTitle; NSNumber *mapLat; NSNumber *mapLng; } @property (nonatomic, retain) IBOutlet MKMapView *mapView; @property (nonatomic, retain) NSString *mapAddress; @property (nonatomic, retain) NSString *mapTitle; @property (nonatomic, retain) NSNumber *mapLat; @property (nonatomic, retain) NSNumber *mapLng; @end And on the pertinent parts of the MapViewController.m file I have: @synthesize mapView, mapAddress, mapTitle, mapLat, mapLng; - (void)viewDidLoad { [super viewDidLoad]; [mapView setMapType:MKMapTypeStandard]; [mapView setZoomEnabled:YES]; [mapView setScrollEnabled:YES]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = mapLat; //40.105085; region.center.longitude = mapLng; //-83.005237; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [mapView setRegion:region animated:YES]; [mapView setDelegate:self]; CourseAnnotation *ann = [[CourseAnnotation alloc] init]; ann.title = mapTitle; ann.subtitle = mapAddress; ann.coordinate = region.center; [mapView addAnnotation:ann]; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

  • How to disable multiple touches on a ScrollView and UIImage

    - by Rob
    I have a scrollview that I am loading images into that the user can touch and play a sound. However, the program is getting confused when I press one image with one finger and then another one with a different finger. It thinks you are pushing the same button again and therefore plays the sound again (so you have two of the same sounds playing at the same time even though you may have pressed a different sound button). I tried setting exclusiveTouch for each UIImage but that didn't seem to work in this case for some reason. What am I missing or is there a better way to do this? Here is some code: for creating buttons.... - (void) createButtons { CGRect myFrame = [self.outletScrollView bounds]; CGFloat gapX, gapY, x, y; int columns = 3; int myIndex = 0; int viewWidth = myFrame.size.width; int buttonsCount = [g_AppsList count]; float actualRows = (float) buttonsCount / columns; int rows = buttonsCount / columns; int buttonWidth = 100; int buttonHeight = 100; if (actualRows > rows) rows++; //set scrollview content size to hold all the glitter icons library gapX = (viewWidth - columns * buttonWidth) / (columns + 1); gapY = gapX; y = gapY; int contentHeight = (rows * (buttonHeight + gapY)) + gapY; [outletScrollView setContentSize: CGSizeMake(viewWidth, contentHeight)]; UIImage* myImage; NSString* buttonName; //center all buttons to view int i = 1, j = 1; for (i; i <= rows; i++) { //calculate gap between buttons gapX = (viewWidth - (buttonWidth * columns)) / (columns + 1); if (i == rows) { //this is the last row, recalculate gap and pitch gapX = (viewWidth - (buttonWidth * buttonsCount)) / (buttonsCount + 1); columns = buttonsCount; }//end else x = gapX; j = 1; for (j; j <= columns; j++) { //get shape name buttonName = [g_AppsList objectAtIndex: myIndex]; buttonName = [NSString stringWithFormat: @"%@.png", buttonName]; myImage = [UIImage imageNamed: buttonName]; TapDetectingImageView* imageView = [[TapDetectingImageView alloc] initWithImage: myImage]; [imageView setFrame: CGRectMake(x, y, buttonWidth, buttonHeight)]; [imageView setTag: myIndex]; [imageView setContentMode:UIViewContentModeScaleToFill]; [imageView setUserInteractionEnabled: YES]; [imageView setMultipleTouchEnabled: NO]; [imageView setExclusiveTouch: YES]; [imageView setDelegate: self]; //add button to current view [outletScrollView addSubview: imageView]; [imageView release]; x = x + buttonWidth + gapX; //increase button index myIndex++; }//end for j //increase y y = y + buttonHeight + gapY; //decrease buttons count buttonsCount = buttonsCount - columns; }//end for i } and for playing the sounds... - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //stop playing theAudio.stop; // cancel any pending handleSingleTap messages [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(handleSingleTap) object:nil]; UITouch* touch = [[event allTouches] anyObject]; NSString* filename = [g_AppsList objectAtIndex: [touch view].tag]; NSString *path = [[NSBundle mainBundle] pathForResource: filename ofType:@"m4a"]; theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio prepareToPlay]; [theAudio setNumberOfLoops:-1]; [theAudio setVolume: g_Volume]; [theAudio play]; } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { BOOL allTouchesEnded = ([touches count] == [[event touchesForView:self] count]); if (allTouchesEnded) { //stop playing theAudio.stop; }//end if //stop playing theAudio.stop; }

  • NSString copy not copying?

    - by Scotty Allen
    NSString *myString = @"sample string"; NSString *newString = [NSString stringWithString: myString]; If I set a breakpoint after these two lines, the pointer for myString is the same as the pointer for newString. WTF? Isn't NSString copy supposed to return a pointer to a new object? Or am I missing something fundamental about how copy is supposed to work?

  • Get directory contents in date modified order

    - by nevan
    Is there an method to get the contents of a folder in a particular order? I'd like an array of file attribute dictionaries (or just file names) ordered by date modified. Right now, I'm doing it this way: get an array with the file names get the attributes of each file store the file's path and modified date in a dictionary with the date as a key Next I have to output the dictionary in date order, but I wondered if there's an easier way? If not, is there a code snippet somewhere which will do this for me? Thanks.

  • Instruments (Leaks) and NSDateFormatter

    - by Cal
    When I run my iPhone app with Instruments Leaks and parse a bunch of NSDates using NSDateFormatter my memory goes up about 1mb and stays even though these NSDates should be dealloc'd after the parsing (I just discard them if they aren't new). I thought the malloc (in my heaviest stack trace below) could become part of the NSDate but I also thought it could be memory that only used during some intermediate step in parsing. Does anyone know which one it is or how to find out? Also, is there a way to put a breakpoint on NSDate dealloc to see if that memory is really being reclaimed? Here's what my date formatter looks like for parsing these dates: df = [[NSDateFormatter alloc] init]; [df setDateFormat:@"EEE, d MMM yyyy H:m:s z"]; Here's the Heaviest Stack trace when the memory bumps up and stays there: 0 libSystem.B.dylib 208.80 Kb malloc 1 libicucore.A.dylib 868.19 Kb icu::ZoneMeta::getSingleCountry(icu::UnicodeString const&, icu::UnicodeString&) 2 libicucore.A.dylib 868.66 Kb icu::ZoneMeta::getSingleCountry(icu::UnicodeString const&, icu::UnicodeString&) 3 libicucore.A.dylib 868.67 Kb icu::ZoneMeta::getSingleCountry(icu::UnicodeString const&, icu::UnicodeString&) 4 libicucore.A.dylib 868.67 Kb icu::DateFormatSymbols::initZoneStringFormat() 5 libicucore.A.dylib 868.67 Kb icu::DateFormatSymbols::getZoneStringFormat() const 6 libicucore.A.dylib 868.67 Kb icu::SimpleDateFormat::subParse(icu::UnicodeString const&, int&, unsigned short, int, signed char, signed char, signed char*, icu::Calendar&) const 7 libicucore.A.dylib 868.67 Kb icu::SimpleDateFormat::parse(icu::UnicodeString const&, icu::Calendar&, icu::ParsePosition&) const 8 libicucore.A.dylib 868.67 Kb icu::DateFormat::parse(icu::UnicodeString const&, icu::ParsePosition&) const 9 libicucore.A.dylib 868.67 Kb udat_parse 10 CoreFoundation 868.67 Kb CFDateFormatterGetAbsoluteTimeFromString 11 CoreFoundation 868.67 Kb CFDateFormatterCreateDateFromString 12 Foundation 868.67 Kb -[NSDateFormatter getObjectValue:forString:range:error:] 13 Foundation 868.75 Kb -[NSDateFormatter getObjectValue:forString:errorDescription:] 14 Foundation 868.75 Kb -[NSDateFormatter dateFromString:] Thanks!

  • NSBorderlessWindow not responding to CMD-W/CMD-M

    - by Sean
    I have an NSBorderlessWindow subclass of NSWindow with a transparent and non-opaque background (so it's non-rectangular in appearance). I've added my own buttons to function as the close and minimize buttons when I click them, but for some reason the window will not respond to CMD-W or CMD-M like a normal one does. I have my NSWindow subclass set to return YES to canBecomeKeyWindow and canBecomeMainWindow. My NIB still has all the standard menu items in it that are there when you create a new project - including the "Minimize" item in the Window menu with the default shortcut CMD-M defined. It's hooked up to send performMiniaturize: to the first responder. However it is not enabled when the app is run, so it seems like it must be asking the window if it can minimize and the window says no or something. (I'm still very new to OSX/Cocoa.) What am I missing? Also, and maybe this is related, my borderless window has a shadow enabled - but unlike a normal titled window, when I make my window the active/front window by clicking on it, the shadow doesn't change. Normally an OSX focused window has a slightly larger/darker shadow to make it stand out more but mine never changes the shadow. It's like I'm missing something to make the OS treat this window as a real/normal/main window or something and as a result I lose the shadow change and functioning CMD-W/CMD-M.

  • invalid context 0x0 under iOS 7.0 and system degradation

    - by Alex
    I've read as many search results I could find on this dreaded problem, unfortunatelly, each one seems to focus on a specific function call. My problem is that I get the same error from multiple functions, which I am guessing are being called back from functions that I use. To make matters worse, the actual code is within a custom private framework which is being imported in another project, and as such, debugging isn't as simple? Can anyone point me to the right direction? I have a feeling I'm calling certain methods wrongly or with bad context, but the output from xcode is not very helpful at this point. : CGContextSetFillColorWithColor: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability.

  • NSButton argument binding doesn't pass argument?

    - by Jeff
    I have a NSCollectionView with a NSButton in the collection view item. The xib's owner is set to my BatchListViewController and the controller has the method @interface BatchListViewController : NSViewController -(IBAction)another_click; @end I set the binding for target to be: This works fine but I also want to send the underlying model to the another_click method. According to the Apple docs, The objects specified in the argument bindings are passed as parameters to the selector specified in the target binding when the NSButton is clicked. So I set the binding for argument to be: This runs fine if I keep the selector method's signature the same another_click: but if I change it to -(IBAction)another_click:(id)arg; I get the dreaded error: BatchListViewController another_click]: unrecognized selector sent to instance What am I doing wrong? Apple's docs say this is possible but I haven't been able to find an example of this working. Even other SO threads are saying this isn't possible but that can't be right.

  • How do I access variable values from one view controller in another?

    - by Thomas
    Hello all, I have an integer variable (time) in one view controller whose value I need in another view controller.

[super viewDidLoad]; } I'm kind of unclear on when @property and @synthesize is necessary. Is that the case in this situation? Any help would be greatly appreciated. Thanks! Thomas

Here's a screenshot of what I mean.

  • drawRect context Error

    Hi, I heard that a lot of people get a context error by not using drawRect Now I have this: - (void)drawRect:(CGRect)rect { NSLog(@"drawRect: Starts"); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetRGBStrokeColor(context, 1.0, 1.0, 1.0, 1.0); CGContextSetLineWidth(context, 3.0); CGContextMoveToPoint(context, lineStart.x, lineStart.y); CGContextAddLineToPoint(context, lineEnd.x, lineEnd.y); CGContextStrokePath(context); } Error: <Error>: CGContextSetRGBStrokeColor: invalid context Which had work on previous programs, but not on this one. Whats different: I have a view controller, which calls this UIView: -(void)createLine:(CGPoint)start:(CGPoint)end { NSLog(@"createLine: Starts"); lineEnd = start; lineStart = end; self = [super initWithFrame:drawRect:CGRectMake(fmin(lineStart.x, lineEnd.x), fmin(lineStart.y, lineEnd.y), fabs(lineStart.x - lineEnd.x), fabs(lineStart.y - lineEnd.y))]; } This is my first question, and I am not sure how much info code I should be putting here so be easy on me :D Thanks

  • On iPhone, how do I show a login screen to get username and password before giving access to iPhone

    - by MikeN
    On iPhone, how do I show a login screen to get username and password before giving access to iPhone app? Also, does the iPhone store a cookie to the secure website like a web browser? I was thinking of giving users to my website a long API key to store in the settings of their iPhone instead of asking them to login with a username/password (seems to be the Slicehost iPhone app approach.) Which is the best way to get a user to login securely? I have full control over the design of the iPhone app and website so have a lot of flexibility.
