  • xcode - warning there's no getter/setter for property not even mentioned in the code!!

    - by alexeyndru
    I got the warning : property 'textField' requires method '-textField' to be defined - use @synthesize, @dynamic or provide a method implementation. Now, there is no such property defined in my project! More bizarre, if I just click save in Interface builder and build again, the build is successful - though, right on the line with '@end' the warning appears. Also weird: if I begin to write some code ..and then delete it just the way it was before writing it (maybe not code..anything) and then build&go the warning with the textField appears again. Could be a bug of sdk? What could be happening?

  • UITextView disabling text selection

    - by dizy
    I'm having a hard time getting the UITextView to disable the selecting of the text. I've tried: canCancelContentTouches = YES; I've tried subclassing and overwriting: - (BOOL)canPerformAction:(SEL)action withSender:(id)sender (But that gets called only After the selection) - (BOOL)touchesShouldCancelInContentView:(UIView *)view; (I don't see that getting fired at all) - (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view; (I don't see that getting fired either) What am I missing ?

  • The item you tried to buy is no longer available [Environment: Sandbox]

    - by Ansari
    I am trying to put In App purchase in my application. I had setup a consumable product which was working fine in Sandbox environment. Now i just made a new product which is non-consumable with new price tier, and deleted the old one. Update my code, with the new Product ID. When request is sent, it properly shows the right Product with newly added price tier, But when you tap on Buy button it gives you the error "The item you tried to buy is no longer available [Environment: Sandbox]". Any idea ?

  • How to wait until location is completely found? (Core Location)

    - by sudo rm -rf
    Hello. I have a problem within my app. I'm trying to find the user's location to the best preciseness in order to determine their zip-code. Currently I have a button that, when pressed, starts a method named locateMe. -(IBAction)locateMe; { self.locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; Then I've implemented didUpdateToLocation: -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation; { NSLog(@"Found location! %f,%f",newLocation.coordinate.latitude,newLocation.coordinate.longitude); } I had previously done much more complicated stuff in didUpdateToLocation but as I tested some things I realized that the first location it found was not precise in the least. So, I put the NSLog call in there and it gave me an output similar to below... Found location! 39.594093,-98.614834 Found location! 39.601372,-98.592171 Found location! 39.601372,-98.592171 Found location! 39.611444,-98.538196 Found location! 39.611444,-98.538196 As you can see, it first gives me a value which is not correct, which was causing problems within my app because it wasn't giving the correct location. So, here's my question. Is there any way I can wait for the location manager to finish finding the most precise location? Thanks in advance! EDIT: I'm wanting something like this: if (newLocation.horizontalAccuracy <= locationManager.desiredAccuracy) { } But it never gets called!

  • How to check for an active Internet Connection on iPhone SDK?

    - by Brock Woolf
    I would like to check to see if I have an Internet connection on the iPhone using the Cocoa Touch libraries. I came up with a way to do this using an NSUrl. The way I did it seems a bit unreliable (because even Google could one day be down and relying on a 3rd party seems bad) and while I could check to see for a response from some other websites if Google didn't respond, it does seem wasteful and an unnecessary overhead on my application. - (BOOL) connectedToInternet { NSString *URLString = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com"]]; return ( URLString != NULL ) ? YES : NO; } Is what I have done bad? (Not to mention 'stringWithContentsOfURL' is deprecated in 3.0) And if so what is a better way to accomplish this?

  • Renderbuffer Width (Open GL ES)

    - by Josh Elsasser
    I'm currently experiencing an issue with an Open GL ES renderbuffer where the backing and width are are both set to 15. Is there any way to set them to the width of 320 and 480? My project is built up on Apple's EAGLView class and ES1Renderer, but I've moved it from the app delegate to a controller. I also moved the CADisplayLink outside of it (I update my game logic with the timestamp from this) Any help would be greatly appreciated. I add the glview to the window as follows: CGRect applicationFrame = [[UIScreen mainScreen] applicationFrame]; [window addSubview:gameController.glview]; [window makeKeyAndVisible]; I synthesize the controller and the glview within it. The EAGLView and Renderer are otherwise unmodified. Renderer Initialization: // Get the layer CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = TRUE; eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:FALSE], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; renderer = [[ES1Renderer alloc] init]; Render "resize from layer" Method - (BOOL)resizeFromLayer:(CAEAGLLayer *)layer { // Allocate color buffer backing based on the current layer size glBindRenderbufferOES(GL_RENDERBUFFER_OES, colorRenderbuffer); [context renderbufferStorage:GL_RENDERBUFFER_OES fromDrawable:layer]; glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_WIDTH_OES, &backingWidth); glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_HEIGHT_OES, &backingHeight); NSLog(@"Backing Width:%i and Height: %i", backingWidth, backingHeight); if (glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES) != GL_FRAMEBUFFER_COMPLETE_OES) { NSLog(@"Failed to make complete framebuffer object %x", glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES)); return NO; } return YES; }

    - by Viral
    hi friends I am making a book application, in that for moving to next topic i am keeping a button.

  • NSSegmentedControl -selectedSegment always returns 0

    - by SphereCat1
    I have an NSSegmentedControl with two segments set to "Select None" mode in Interface Builder. No matter what I try, I can't get -selectedSegment to return anything but 0, even though segment 0 is even disabled by default and can't possibly be selected. Here's the relevant function that gets called when you click any segment on the control: -(IBAction)changeStep:(id)sender { [stepContainer setHidden:TRUE]; [(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]] removeFromSuperview]; switch ([[navigationButton cell] selectedSegment]) { case 0: [wizard setStep:(NSInteger *)[wizard step]-1]; break; case 1: [wizard setStep:(NSInteger *)[wizard step]+1]; break; default: break; } //[[navigationButton cell] setSelected:FALSE forSegment:[navigationButton selectedSegment]]; if ([wizard step] > 0) { [wizard setStep:0]; [navigationButton setEnabled:FALSE forSegment:0]; } NSLog(@"%d", [wizard step]); [stepContainer addSubview:(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]]]; [stepContainer setHidden:FALSE withFade:TRUE]; } I've also tried using -isSelectedForSegment, but it has the same result. Any help you can provide would be awesome, I have no idea what I'm doing wrong. Thanks! SphereCat1

  • OO model for nsxmlparser when delegate is not self

    - by richard
    Hi, I am struggling with the correct design for the delegates of nsxmlparser. In order to build my table of Foos, I need to make two types of webservice calls; one for the whole table and one for each row. It's essentially a master-query then detail-query, except the master-query-result-xml doesn't return enough information so i then need to query the detail for each row. I'm not dealing with enormous amounts of data. Anyway - previously I've just used NSXMLParser *parser = [[NSXMLParser alloc]init]; [parser setDelegate:self]; [parser parse]; and implemented all the appropriate delegate methods in whatever class i'm in. In attempt at cleanliness, I've now created two separate delegate classes and done something like: NSXMLParser *xp = [[NSXMLParser alloc]init]; MyMasterXMLParserDelegate *masterParserDelegate = [[MyMasterXMLParser]alloc]init]; [xp setDelegate:masterParserDelegate]; [xp parse]; In addition to being cleaner (in my opinion, at least), it also means each of the -parser:didStartElement implementations don't spend most of the time trying to figure out which xml they're parsing. So now the real crux of the problem. Before i split out the delegates, i had in the main class that was also implementing the delegate methods, a class-level NSMutableArray that I would just put my objects-created-from-xml in when -parser:didEndElement found the 'end' of each record. Now the delegates are in separate classes, I can't figure out how to have the -parser:didEndElement in the 'detail' delegate class "return" the created object to the calling class. At least, not in a clean OO way. I'm sure i could do it with all sorts of nasty class methods. Does the question make sense? Thanks.

  • Render only a portion of a PDF on iPhone/iPad

    - by Infinity
    Hello guys! I am rendering my pdf in an UIView's drawRect method. Here's my code: - (void)drawRect:(CGRect)rect2 { NSString *filename = @"lol.pdf"; CFStringRef path = CFStringCreateWithCString (NULL, [filename UTF8String], kCFStringEncodingUTF8); CFURLRef url = CFURLCreateWithFileSystemPath (NULL, path, kCFURLPOSIXPathStyle, 0); CGPDFDocumentRef pdf = CGPDFDocumentCreateWithURL(url); CGPDFPageRef page = CGPDFDocumentGetPage (pdf, 1); CGAffineTransform m; CGContextRef context = UIGraphicsGetCurrentContext(); CGRect aRect = CGRectMake(0, 0, 768, 1024); CGContextTranslateCTM(context, 0.0, aRect.size.height); CGContextScaleCTM(context, 1.0, -1.0); m = CGPDFPageGetDrawingTransform (page, kCGPDFMediaBox, aRect, 0, YES); CGContextSaveGState (context); CGContextConcatCTM (context, m); CGContextClipToRect (context,CGPDFPageGetBoxRect (page, kCGPDFCropBox)); CGContextDrawPDFPage (context, page); CGContextRestoreGState (context); } It renders the whole pdf. How can I render only a part from it? Can you help me with it?

  • iPhone write to file (alternative directory)

    - by strider2k
    New to iPhone 3.2, Apple introduced File-Sharing support. Details can be found at https://developer.apple.com/iphone/library/releasenotes/General/WhatsNewIniPhoneOS/Articles/iPhoneOS3_2.html#//apple_ref/doc/uid/TP40009337-SW1 . Now, most examples floating around in the web demonstrates writing to the documents directory. What if I want to write files from my app but I don't want the user to be able to see it via iTunes? I'm looking at the Files and Networking section of the iPhone OS Programming Guide and I'm unsure what would be a good alternative to the documents directory for writing files to hide from the user and not be rejected by Apple's review team.

  • How to rotate a UIImageView?

    - by jkally
    It's quite frustrating not to be able to do such a simple task: I have an "app" with a single viewcontroller, and in it a single UIImageView, that's initialized to a specific image at potrtait mode. Now when the iPhone gets roteated to landscape mode and the shouldAutorotateToInterfaceOrientation event fires, at which I return YES, my resulting UIImageView looks totally screwed up: either the image is stretched so to fill landscape mode frame (which looks ridiculuous of course) or the top and bottom of the image are cropped. How can I have my UIImageview and the contained image handle the device rotation gracefully, and display normal looking image at landscape mode as well?
