• Send custom headers with UIWebView loadRequest

  - by Thomas Clayson

  I want to be able to send some extra headers with my UIWebView loadRequest method. I have tried: NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.reliply.org/tools/requestheaders.php"]]; [req addValue:@"hello" forHTTPHeaderField:@"aHeader"]; [self.theWebView loadRequest:req]; I have also tried subclassing the UIWebView and intercepting the - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType method. In that method I had a block of code which looked like this: NSMutableURLRequest *newRequest = [request mutableCopy]; for(NSString *key in [customHeaders allKeys]) { [newRequest setValue:[customHeaders valueForKey:key] forHTTPHeaderField:key]; } [self loadRequest:newRequest]; But for some unknown reason it was causing the web view to not load anything (blank frame) and the error message NSURLErrorCancelled (-999) comes up (all known fixes don't fix it for me). So I am at a loss as to what to do. How can I send a custom header along with a UIWebView request? Many thanks!

• Before data is entered, is there a way to make a grouped table graphic placeholder?

  - by Matt Winters

  I have a grouped table with 3 sections, each section with a title. The 1st and 3rd sections always have only 1 row of information so before any user data is entered, I just put some words like "Enter Data Here..." as placeholder text. This text is edited (replaced) by the user with their own actual data. No problem. The 2nd section however will contain several rows of information entered by user and I'd prefer not to enter placeholder data in row 0, having the user Edit the first row of data then Add subsequent rows. If the numberOfRowsInSection is set to 0, the title for the 3rd section comes close to the title for the 2nd section and it looks ugly. The best that I could come with, and I don't know to do it, is to have a fake graphic placeholder on the striped background (between the 2nd and third titles) that looks like a single row in the 2nd section, put "Enter Data Here..." text in the graphic, and then the first row of actual data entered and all subsequent rows will cover it up. Can anyone tell me how to do this or offer a better suggestion. Thanks.

• UISearchDisplayController changing row height

  - by tewha

  I've set my UITableView row height to in Interface Builder to 54.0. I have a UISearchDisplayController on that view. When the user taps the search bar in it, the table resizes properly. However, when they start typing (and actually doing the search) the row height decreases. It stays wrong until the search taps Cancel. I could find no documentation on this behavior on Apple's site. I've tried setting the row height in UISearchDisplayDelegate delegate calls. This might be the right approach, but I don't know the details and couldn't get it ti work. I've also tried implementing -- (CGFloat)tableView:(UITableView *)tableView -heightForRowAtIndexPath:(NSIndexPath *)indexPath;. This worked, but I have thousands of entries in this list and can't take the performance hit. What's the right way to fix this?

• Core Data Relationship List

  - by Dylan Copeland

  I'm not sure whether or not this is the appropriate way of doing this, but I was wondering what's the best way to approach a relationship to a value in a list with Core Data? For example, say you have a 'person' entity. Each person can have a different 'hair color'. I'm trying to basically define the hair colors in my data model and allow the 'person' entity to have a relationship to their given 'hair color. Is this possible? Good idea or bad? Thanks in advance.

• NSOperation and UIKit problem

  - by Infinity

  Hello guys! I am doing my download with an object which was inherited from NSOperation. I have read the documentation and when my operation finished I must call the [self.delegate performSelectorOnMainThread:@selector(operationDidFinish:) withObject:self waitUntilDone:YES]; method. It needs to be called on the main thread, because the UIKit is not thread safe and the documentation says this in these non thread safe frameworks cases. In the delegate method I am drawing a pdf or an image, but because it is drawn on the main thread the User Interface is very laggy until the drawing is finished. Maybe can you suggest me a good way to avoid this problem?

• Texture2D problem

  - by Anders Karlsson

  I have a problem that is driving me crazy, I want to write a number of texts on the screen using Texture2D however I only seem to be able to write the first one. If I individually write one of the labels it works but not if I write all of them, only the first label is displayed. Let me show some code: -(void)drawText:(NSString*)theString AtX:(float)X Y:(float)Y withFont:(UIFont*)aFont { // set color glColor4f(1, 0, 0, 1.0); // Enable modes needed for drawing glEnableClientState(GL_TEXTURE_COORD_ARRAY); Texture2D* textTexture = [[Texture2D alloc] initWithString:theString dimensions:viewSize // 320x480 alignment:UITextAlignmentLeft font:aFont]; glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); [textTexture drawInRect:CGRectMake(X,Y,1,1)]; glDisableClientState(GL_TEXTURE_COORD_ARRAY); [textTexture release]; } When I call this drawText once it seems to display the text properly, but if I call it a second time nothing seems to be displayed. Somebody has an idea what it could be? The states like GL_BLEND and GL_TEXTURE_2D have been enabled in the view setup function. In the Texture2D the dimensions are 512x512 as I pass the whole screen to function. If I don't pass that the text gets enlarged and fuzzy. I am a bit uncertain about that parameter. TIA for any help.

• Newbie Objective C developer question

  I have been looking everywhere for an answer to this question - perhaps I'm looking in the wrong places. Also, I'm brand new to Objective C although I have around 10 years of experience as a developer. for this code: [receiver makeGroup:group, memberOne, memberTwo, memberThree]; what would the method definition look like? - (void)makeGroup:(Group *)g, (NSString *)memberOne, ...? Thanks for any help you can provide. I know this is probably very simple... Thanks, R

• Callback for camera shutter open event

  - by Raj

  Hi all, I have been working around in UIImagePickerController and am struck with a problem where I need to get the precise moment when the camera shutter opens in UIImagePickerController when the source type is set to camera (UIImagePickerControllerSourceTypeCamera). I have done some googling around and have realized that no one had such strange requirement! I looked around the docs of UIImagePickerController and UIImagePickerControllerDelegate hoping to get some delegate method / callback indicating the camera shutter open event, but did not find any. Any suggestions? Thanks for any help, Raj Pawan

• presentModalViewController does not want to work when called from a protocol method

  - by johnbdh

  I have a subview that when double tapped a protocol method on the subview's parent view controller is called like this... - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *theTouch = [touches anyObject]; if (theTouch.tapCount == 1) { } else if (theTouch.tapCount == 2) { if ([self.delegate respondsToSelector:@selector(editEvent:)]) { [self.delegate editEvent:dictionary]; } } } Here is the protocol method with the dictionary consuming code removed... - (void)editEvent:(NSDictionary){ EventEditViewController *eventEditViewController = [[EventEditViewController alloc] initWithNibName:@"EventEditViewController" bundle:nil]; eventEditViewController.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:eventEditViewController]; [self presentModalViewController:navigationController animated:YES]; [eventEditViewController release]; } The protocol method is called and runs without any errors but the modal view does not present itself. I temporarily copied the protocol method's code to an IBAction method for one of the parent's view button's to isolate it from the subview. When I tap this button the modal view works fine. Can anyone tell me what I am doing wrong? Why does it work when executed from a button on the parent view, and not from a protocol method called from a subview. Here is what I have tried so far to work around the problem... Restarted xCode and the simulator Ran on the device (iTouch) Presenting eventEditViewController instead of navigationController Using Push instead of presentModal. delaying the call to the protocol with performSelector directly to the protocol, to another method in the subview which calls the protocol method, from the protocol method to another method with the presentModal calls. Using a timer. I have it currently setup so that the protocol method calls a known working method that presents a different view. Before calling presentModalViewController it pops a UIAlertView which works every time, but the modal view refuses to display when called via the protocol method. I'm stumped. Perhaps it has something to do with the fact that I am calling the protocol method from a UIView class instead of a UIViewController class. Maybe I need to create a UIViewController for the subView?? Thanks, John

• Objective C selector memory managment (does this leak memory)?

  - (IBAction) someButtonCall { if(!someCondition) { someButtonCallBack = @selector(someButtonCall); [self presentModalViewController:someController animated:YES]; } else ... } //Called from someController - (void) someControllerFinished:(BOOL) ok { [self dismissModalViewControllerAnimated:YES]; if(ok) [self performSelector:someButtonCallBack]; else ... } I'm wondering if the user keeps getting into the !someCondition clause if the selector is leaked by assigning a new selector each time (the code above is hypothetical and not what i'm doing). Any help is appreciated. Thanks, James Jones

• Cocoa Touch UITableView Alphabetical '#' Match All Unmatched

  - by Kevin Sylvestre

  I have a UITableView containing names that I would like to group (and sort) by the first letter (similar to the Address Book application). I am currently able to match any section ('A'-'Z') using: // Sections is an array of strings "{search}" and "A" to "Z" and "#". NSString *pattern = [self.sections objectAtIndex:section]; NSPredicate *predicate = nil; // Ignore search pattern. if ([pattern isEqualToString:@"{search}"]) return nil; // Non-Alpha and Non-Diacritic-Alpha (?). if ([pattern isEqualToString:@"#"]); // Default case (use case and diacritic insensitivity). if (!predicate) predicate = [NSPredicate predicateWithFormat:@"name beginswith[cd] %@", pattern]; // Return filtered results. return [self.friends filteredArrayUsingPredicate:predicate]; However, matching for the '#' eludes me. I tried constructing a REGEX match using: [NSPredicate predicateWithFormat:@"name matches '[^a-zA-Z].*'"]; But this fails for diacritic-alpha (duplicate rows appear). Any ideas would be greatly appreciated! Thanks.

  I am using the following piece of code to hide the background on a UISearchBar: [[searchView.subviews objectAtIndex:0] setHidden:YES]; Pretty simple, but I worry about hard coding a position in a subview list. So I went looking for the UISearchBarBackground.h file and cannot find it. Does any know where the definition is hiding?

• Can I include a NSUserDefault password test in AppDelegate to load a loginView?

  - by Michael Robinson

  I have a name and password in NSUserDefaults for login. I want to place a test in my AppDelegate.m class to test for presence and load a login/signup loginView.xib modally if there is no password or name stored in the app. Here is the pulling of the defaults: -(void)refreshFields { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; usernameLabel.text = [defaults objectForKey:kUsernameKey]; passwordLabel.text = [defaults objectForKey:kPasswordKey]; Here is the tabcontroller loading part: - (void)applicationDidFinishLaunching:(UIApplication *)application { firstTab = [[FirstTab alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *firstNavigationController = [[UINavigationController alloc] initWithRootViewController:firstTab]; [firstTab release]; secondTab = // EDITED FOR SPACE thirdTab = // EDITED FOR SPACE tabBarController = [[UITabBarController alloc] init]; tabBarController.viewControllers = [NSArray arrayWithObjects:firstNavigationController, secondNavigationController, thirdNavigationController, nil]; [window addSubview:tabBarController.view]; [firstNavigationController release]; [secondNavigationController release]; [thirdNavigationController release]; [self logout]; [window makeKeyAndVisible]; Here is where the loginView.xib loads automatically: - (void)logout { loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil]; UINavigationController *loginNavigationController = [[UINavigationController alloc] initWithRootViewController:loginViewController]; [loginViewController release]; [tabBarController presentModalViewController:loginNavigationController animated:YES]; [loginNavigationController release]; } I want to replace the above autoload with a test similar to below (that works) using IF-ELSE - (void)logout { if ([usernameLabel.text length] == 0 || [passwordLabel.text length] == 0) { loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil]; UINavigationController *loginNavigationController = [[UINavigationController alloc] initWithRootViewController:loginViewController]; [loginViewController release]; [tabBarController presentModalViewController:loginNavigationController animated:YES]; [loginNavigationController release]; }else { [window addSubview:tabBarController.view];} Thanks in advance, I'm totally lost on this.

• Are Subversion 1.6 & Xcode 3.2 compatible?

  - by Meltemi

  Trying to get Xcode to work with Subversion server. Server: Subversion upgraded to 1.6.9 (Mac OS X Leopard 10.5.8) Client: Xcode 3.2.1 (Snow Leopard 10.6.2 with Subversion 1.6.5 though not sure that matters) Repository on server is setup and working fine via command line. However, I get an error when trying to create the Repository connection in Xcode: Error: 160043 (Unsupported FS format) Description: Expected FS format '2'; found format '4' a Google search seems to say that the server needs to be updated...but it's running 1.6.9 which is the most current version I'm aware of. Anyone know how to make this work? Is it even possible? I'm well aware of the command line usage but I would like to get Xcode & SVN talking... Revisiting this after some time: Using command line: username$ svn+ssh://hostname/Library/Subversion/Repository/test yields the same result: Description: Expected FS format '2'; found format Can anyone verify that I need to upgrade Subversion on the client machine to match version on server (1.6.9)?!? was hoping i wouldn't have to unless it was a "major" revision (ie. 1.5.x - 1.6.x)

• ASIHTTPRequest code design

  - by nico

  I'm using ASIHTTPRequest to communicate with the server asynchronously. It works great, but I'm doing requests in different controllers and now duplicated methods are in all those controllers. What is the best way to abstract that code (requests) in a single class, so I can easily re-use the code, so I can keep the controllers more simple. I can put it in a singleton (or in the app delegate), but I don't think that's a good approach. Or maybe make my own protocol for it with delegate callback. Any advice on a good design approach would be helpful. Thanks.

• How to Anti-Alias Layers in iPhoneOS

  - by Shannon A.

  We've had Reiner Knizia's Money out for a couple of months now. It's done pretty well, and so we've been updating it as time allows. However, one thing continues to bug me. I've never been able to get my layered cards to anti-alias correctly. Here's a sample: Cards that are laid straight are very clean, but whenever they're angled the black lines around the cards get jagged. I've tried this depending on both lines implicit to the artwork and lines drawn through drawRect:, and they both do the same thing. I've tried the edgeAntiAliasingMask and it doesn't do a thing as far as I can tell. I've tried masksToBounds for the sublayers set to NO and YES. Right now my card is set up as a CALayer that has sub-CALayers for the front and the back, plus for a few other things like a lightening mask and a darkening mask. Here's some snippets of the code: CArdLayer *theCardLayer = [CArdLayer layer]; theCardLayer.edgeAntialiasingMask = kCALayerLeftEdge | kCALayerRightEdge | kCALayerBottomEdge | kCALayerTopEdge; theCardLayer.front = [CALayer layer]; theCardLayer.front.edgeAntialiasingMask = kCALayerLeftEdge | kCALayerRightEdge | kCALayerBottomEdge | kCALayerTopEdge; theCardLayer.front.bounds = theCardLayer.bounds; theCardLayer.front.masksToBounds = YES; theCardLayer.front.contents = (id)[cardDrawing CGImage]; [theCardLayer addSublayer:theCardLayer.front]; Etc ... Any ideas on how to make the cards actually anti-alias?

• Setting UIImage dimensions on UITableViewCell image

  - by bbrown

  I've got a standard UITableViewCell where I'm using the text and image properties to display a favicon.ico and a label. For the most part, this works really well since UIImage supports the ICO format. However, some sites (like Amazon.com say) have favicon.icos that make use of the ICO format's ability to store multiple sizes in the same file. Amazon stores four different sizes, all the way up to 48x48. This results in most images being 16x16 except for a few that come in at 32x32 or 48x48 and make everything look terrible. I have searched here, the official forum, the documentation, and elsewhere without success. I have tried everything that I could think of to constrain the image size. The only thing that worked was an undocumented method, which I'm not about to use. This is my first app and my first experience with Cocoa (came from C#). In case I wasn't clear in what I'm looking for, ideally the advice would center around setting the dimensions of the UIImage so that the 48x48 version would scale down to 16x16 or a method to tell UIImage to use the 16x16 version present in the ICO file. I don't necessarily need code: just a suggestion of an approach would do me fine. Does anyone have any suggestions? (I asked in the official forum as well because I've sunk more than a day into this already. If a solution is posted there, I'll put it here as well.)
