  • Customizing UISlider look

    - by tcurdt
    To customize the visual look of a UISlider you can set the thumb and track images. Part of the track images gets stretched to the appropriate with. From the documentation: A stretchable region sits between two end cap regions. The end caps define the portions of the image that remain as is and are not stretched. The stretchable region is a 1-point wide area between the end caps that can be replicated to make the image appear longer. Now the problem I have is that my stretchable region needs to be more than 1-point wide. (It's a pattern) Unfortunately the 1-point width seems to be hard coded in the SDK. Anyone having an idea how to work around this? Or will I have to write my own slider from scratch for this?

  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • Leak in managedObjectContext save:

    - by Kamchatka
    Hi I have the following piece of code and when I use Instruments/Object Allocations, it tells me that there is a leak there (which goes down to sqlite3MemMalloc). Is there something that I should release? if (![managedObjectContext save:&error]) { NSLog(@"Error while saving."); } The save works well and doesn't trigger an error.

  • UIButton only responds in a small area

    - by Tom Irving
    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.

  • Showing value of UISlider inside App Prefs?

    - by Garrett H
    I have a settings bundle, working perfectly, that I would like to customize a bit. I have, among other things, a PSSliderSpecifier and a PSTitleValueSpecifier. What I would like to do is change the value of the PSTitleValueSpecifier to show the current value of the slider, preferably updating every time the slider's value changes (Actually, what I'd like even more would be displaying the slider's value on the same row as the slider). I know the settings bundle is rather strict about what you're allowed to do in it, but is there any way of doing this?

  • Rotation of ViewController in TabbarController

    - by hanno
    I have a custom UIViewController in a UITabbarController and want to respond to rotation events. When a rotation occurs, the tabbarcontroller and the viewcontroller get rotated. However, the view in the viewcontroller doesn't get redrawn properly: the layout doesn't autoresize and it is black on parts of the screen. The strange thing is that it works when I go to another tab and the back again to my original viewcontroller. What could possibly be wrong? I checked that didRotateFromInterfaceOrientation:fromInterfaceOrientation is being called. However, the view.frame.size values are still the old ones from before the rotation. That's probably not correct.

  • UITextField blurred text

    - by Mike Weller
    I am having a problem with a UITextField's text being blurred/anti-aliased even with a standard font size. The text will appear crisp when the control is the first responder, but blurred again when it loses focus: Does anybody know how to fix this?

  • xcode collect2: ld returned 1 exit status - how to resolve?

    - by Remover
    From what I have read this is supposed to be when the linker (not exactly sure how that works) can't find a symbol. the symbol in question is: SCNetworkReachabilityCreateWithAddress as can be seen from the full error message below. the thing is that the correct framework is added to my target. xcode recognises the symbol OK, i.e. there is no error message in the .m file. the .m file is added to the correct target so I'm not at all sure what to do. Any ideas please? "SCNetworkReachabilityCreateWithAddress", referenced from: -[AppWelcomeVC viewDidLoad] in AppWelcomeVC.o ld: symbol(s) not found collect2: ld returned 1 exit status

  • Memory allocation and release for UIImage in iPhone?

    - by rkbang
    Hello all, I am using following code in iPhone to get smaller cropped image as follows: - (UIImage*) getSmallImage:(UIImage*) img { CGSize size = img.size; CGFloat ratio = 0; if (size.width < size.height) { ratio = 36 / size.width; } else { ratio = 36 / size.height; } CGRect rect = CGRectMake(0.0, 0.0, ratio * size.width, ratio * size.height); UIGraphicsBeginImageContext(rect.size); [img drawInRect:rect]; UIImage *tempImg = [UIGraphicsGetImageFromCurrentImageContext() retain]; UIGraphicsEndImageContext(); return [tempImg autorelease]; } - (UIImage*)imageByCropping:(UIImage *)imageToCrop toRect:(CGRect)rect { //create a context to do our clipping in UIGraphicsBeginImageContext(rect.size); CGContextRef currentContext = UIGraphicsGetCurrentContext(); //create a rect with the size we want to crop the image to //the X and Y here are zero so we start at the beginning of our //newly created context CGFloat X = (imageToCrop.size.width - rect.size.width)/2; CGFloat Y = (imageToCrop.size.height - rect.size.height)/2; CGRect clippedRect = CGRectMake(X, Y, rect.size.width, rect.size.height); //CGContextClipToRect( currentContext, clippedRect); //create a rect equivalent to the full size of the image //offset the rect by the X and Y we want to start the crop //from in order to cut off anything before them CGRect drawRect = CGRectMake(0, 0, imageToCrop.size.width, imageToCrop.size.height); CGContextTranslateCTM(currentContext, 0.0, drawRect.size.height); CGContextScaleCTM(currentContext, 1.0, -1.0); //draw the image to our clipped context using our offset rect //CGContextDrawImage(currentContext, drawRect, imageToCrop.CGImage); CGImageRef tmp = CGImageCreateWithImageInRect(imageToCrop.CGImage, clippedRect); //pull the image from our cropped context UIImage *cropped = [UIImage imageWithCGImage:tmp];//UIGraphicsGetImageFromCurrentImageContext(); CGImageRelease(tmp); //pop the context to get back to the default UIGraphicsEndImageContext(); //Note: this is autoreleased*/ return cropped; } I am using following line of code in cellForRowAtIndexPath to update the image of the cell: cell.img.image = [self imageByCropping:[self getSmallImage:[UIImage imageNamed:@"goal_image.png"]] toRect:CGRectMake(0, 0, 36, 36)]; Now when I add this table view and pop it from navigation controller, I see a memory hike.I see no leaks but memory keeps climbing. Please note that the images changes for each row and I am creating the controller using lazy initialization that is I create or alloc it whenever I need it. I saw on internet many people facing the same issue, but very rare good solutions. I have multiple views using the same way and I see almost memory raised to 4MB within 20-25 view transitions. What is the good solution to resolve this issue. tnx.

  • awakeFromNib and loadView execute for different instances

    - by Kamchatka
    Hi, I'm trying to understand why: NSLog(@"self = %p", self); in awakeFromNib prints a different value than the same NSLog in viewDidLoad? This isn't a huge problem because I don't need the awakeFromNib but I would like to understand how it works. The code that creates the controller is the following: MyViewController *myViewController = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil]; myViewController.image = tmpImage; [self.navigationController pushViewController:myViewController animated:YES]; [myViewController release]; Thanks for any advices!

  • Persist UIWebView content and address after changing views

    - by Momeks
    I am using UIWebView as a web browser on my application and when I open an url with my browser and return back to the main view, then go to browser view, my webview doesn't save the content. So, if I go to google.com and switch views, then again go to the browser view, I have to type the url again to open the webpage! How can I save the web browser's content?

  • How to load a NIB inside of a view in another NIB?

    - 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?

  • Google Docs iphone library error reporting

    - by phil harris
    I'm in the process of adding a Google Docs interface to my iPhone app, and I'm largely following the example in the GoogleDocs.m file from Tom Saxton's example app. The objective-c library I'm using is from http://code.google.com/p/gdata-objectivec-client/wiki/GDataObjCIntroduction The library file used is from gdata-objectivec-client-1.10.0.zip. This service:username:password method is a slight variant of the one found in the Saxton file GoogleDocs.m starting at line 351: - (void)service:(NSString *)username password:(NSString *)password { if(service == nil) { service = [[[GDataServiceGoogleDocs alloc] init] autorelease]; [service setUserAgent:s_strUserAgent]; [service setShouldCacheDatedData:NO]; [service setServiceShouldFollowNextLinks:NO]; (void)[service authenticateWithDelegate:self didAuthenticateSelector:@selector(ticket:authenticatedWithError:)]; } // update the username/password each time the service is requested if (username != nil && [username length] && password != nil && [password length]) [service setUserCredentialsWithUsername:username password:password]; else [service setUserCredentialsWithUsername:nil password:nil]; } // associated callback for service:username:password: method - (void)ticket:(GDataServiceTicket *)ticket authenticatedWithError:(NSError *)error { NSLog(@"%@",@"authenticatedWithError called"); if(error == nil) [self selectBackupRestore]; else { NSLog(@"error code(%d)", [error code]); NSLog(@"error domain(%d)", [error domain]); NSLog(@"localizedDescription(%@)", error.localizedDescription); NSLog(@"localizedFailureReason(%@)", error.localizedFailureReason); NSLog(@"localizedRecoveryOptions(%@)", error.localizedRecoveryOptions); NSLog(@"localizedRecoverySuggestion(%@)", error.localizedRecoverySuggestion); } } Please note the service:username:password method and the callback compile and run fine. The problem is that the callback is passing a non-nil NSError object. I added an NSLog() for every error reporting attribute of NSError and the (Xcode) log output of a test run is below. [Session started at 2010-05-27 12:27:16 -0700.] 2010-05-27 12:27:38.778 iFilebox[74596:207] authenticatedWithError called 2010-05-27 12:27:38.779 iFilebox[74596:207] error code(-1) 2010-05-27 12:27:38.780 iFilebox[74596:207] error domain(499324) 2010-05-27 12:27:38.781 iFilebox[74596:207] localizedDescription(Operation could not be completed.

I was hoping the localizedDescription would be more specific of the error. All I get for the error code value is -1, and the only description of the error is "Operation could not be completed. (com.google.GDataServiceDomain error -1.". Not very helpful. Does anyone know what a GDataServiceDomain error -1 is? Where can I find a full list of all error codes returned, and a description of what they mean?

  • How to smooth the edge of a zig-zag line?

    - by Horace Ho
    Currently I draw a zig-zap line by CGContextMoveToPoint, CGContextAddLineToPoint, and CGContextStrokePath, following touchesMoved events. How can I smooth the edges of the line? Such that when the user draw a circle-like shape, the circle can be more round'ed. The GLPaint example use OpenGL, is that the only way to do it?

  • How can I render an in-memory UIViewController's view Landscape?

    - by Aaron
    I'm trying to render an in-memory (but not in hierarchy, yet) UIViewController's view into an in-memory image buffer so I can do some interesting transition animations. However, when I render the UIViewController's view into that buffer, it is always rendering as though the controller is in Portrait orientation, no matter the orientation of the rest of the app. How do I clue this controller in? My code in RootViewController looks like this: MyUIViewController* controller = [[MyUIViewController alloc] init]; int width = self.view.frame.size.width; int height = self.view.frame.size.height; int bitmapBytesPerRow = width * 4; unsigned char *offscreenData = calloc(bitmapBytesPerRow * height, sizeof(unsigned char)); CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef offscreenContext = CGBitmapContextCreate(offscreenData, width, height, 8, bitmapBytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast); CGContextTranslateCTM(offscreenContext, 0.0f, height); CGContextScaleCTM(offscreenContext, 1.0f, -1.0f); [(CALayer*)[controller.view layer] renderInContext:offscreenContext]; At that point, the offscreen memory buffers contents are portrait-oriented, even when the window is in landscape orientation. Ideas?

  • Few iPhone noob questions

    - by mshsayem
    Why should I declare local variables as 'static' inside a method? Like: static NSString *cellIdentifier = @"Cell"; Is it a performance advantage? (I know what 'static' does; in C context) What does this syntax mean?[someObj release], someObj = nil; Two statements? Why should I assign nil again? Is not 'release' enough? Should I do it for all objects I allocate/own? Or for just view objects? Why does everyone copy NSString, but retains other objects (in property declaration)? Yes, NSStrings can be changed, but other objects can be changed also, right? Then why 'copy' for just NSString, not for all? Is it just a defensive convention? Shouldn't I release constant NSString? Like here:NSString *CellIdentifier = @"Cell"; Why not? Does the compiler allocate/deallocate it for me? In some tutorial application I observed these (Built with IB): Properties(IBOutlet, with same ivar name): window, someLabel, someTextField, etc etc... In the dealloc method, although the window ivar was released, others were not. My question is: WHY? Shouldn't I release other ivars(labels, textField) as well? Why not? Say, I have 3 cascaded drop-down lists. I mean, based on what is selected on the first list, 2nd list is populated and based on what is selected on the second list, 3rd list is populated. What UI components can reflect this best? How is drop-down list presented in iPhone UI? Tableview with UIPicker? When should I update the 2nd, 3rd list? Or just three labels which have touch events? Can you give me some good example tutorials about Core-Data? (Not just simple data fetching and storing on 2/3 tables with 1/2 relationship) How can I know whether my app is leaking memory? Any tools?

  • Create a view like Tweetie's User Profile view

    - by Graeme
    Hi, I'm just wondering if anyone has any idea on how you can create a view that looks like the user profile view in apps like Tweetie, where there are seemingly multiple tables with a couple of normal (straight up and down tables) and then two rows of six cells, which in Tweeties case have the number of followers, following etc. I'm trying to make a similar view for my app, but can't seem to find out the best way to create it. Any tutorials, advice etc. would be appreciated. Thanks. P.S. Here's a picture of the view which I'm trying to recreate.

  • All UITableCells rendered at once... why?

    - by Greg
    I'm extremely confused by the proper behavior of UITableView cell rendering. Here's the situation: I have a list of 250 items that are loading into a table view, each with an image. To optimize the image download, I followed along with Apple's LazyTableImages sample code... pretty much following it exactly. Really good system... for reference, here's the cell renderer within the Apple sample code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // customize the appearance of table view cells // static NSString *CellIdentifier = @"LazyTableCell"; static NSString *PlaceholderCellIdentifier = @"PlaceholderCell"; // add a placeholder cell while waiting on table data int nodeCount = [self.entries count]; if (nodeCount == 0 && indexPath.row == 0) { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:PlaceholderCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:PlaceholderCellIdentifier] autorelease]; cell.detailTextLabel.textAlignment = UITextAlignmentCenter; cell.selectionStyle = UITableViewCellSelectionStyleNone; } cell.detailTextLabel.text = @"Loading…"; return cell; } UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; } // Leave cells empty if there's no data yet if (nodeCount > 0) { // Set up the cell... AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row]; cell.textLabel.text = appRecord.appName; cell.detailTextLabel.text = appRecord.artist; // Only load cached images; defer new downloads until scrolling ends if (!appRecord.appIcon) { if (self.tableView.dragging == NO && self.tableView.decelerating == NO) { [self startIconDownload:appRecord forIndexPath:indexPath]; } // if a download is deferred or in progress, return a placeholder image cell.imageView.image = [UIImage imageNamed:@"Placeholder.png"]; } else { cell.imageView.image = appRecord.appIcon; } } return cell; } So – my implementation of Apple's LazyTableImages system has one crucial flaw: it starts all downloads for all images immediately. Now, if I remove this line: //[self startIconDownload:appRecord forIndexPath:indexPath]; Then the system behaves exactly like you would expect: new images load as their placeholders scroll into view. However, the initial view cells do not automatically load their images without that prompt in the cell renderer. So, I have a problem: with the prompt in the cell renderer, all images load at once. Without the prompt, the initial view doesn't load. Now, this works fine in Apple sample code, which got me wondering what was going on with mine. It's almost like it was building all cells up front rather than just the 8 or so that would appear within the display. So, I got looking into it, and this is indeed the case... my table is building 250 unique cells! I didn't think the UITableView worked like this, I guess I thought it only built as many items as were needed to populate the table. Is this the case, or is it correct that it would build all 250 cells up front? Also – related question: I've tried to compare my implementation against the Apple LazyTableImages sample, but have discovered that NSLog appears to be disabled within the Apple sample code (which makes direct behavior comparisons extremely difficult). Is that just a simple publish setting somewhere, or has Apple somehow locked down their samples so that you can't log output at runtime? Thanks!
