• Mac Quick Look Preview in an NSView or NSImage?

  - by Niko Matsakis

  I am looking for a way (public or otherwise) to get an NSView, NSImage, CGImageRef, etc that shows the QuickLook preview for a file. Essentially the equivalent of QLThumbnailImageCreate() but for the preview. The public APIs I can find do not support this. They allow the creation of a thumbnail image or a QLPreviewPanel. The panel does in fact display the quick look preview, but I cannot get access to the preview's appearance to embed it in other views, nor can I display multiple previews at once. For background, I am writing an app where users can embed links to other files that should be displayed inline, kind of like an <img> tag in HTML. For images like JPGs and PDFs it's easy to figure out what to display. I thought that for other formats I would use Quick Look to generate a nice visual representation of the file's contents. This way the set of formats supported by my application would be easily extensible (just download new Quick Look generators).

• UIWebView is ignoring cookies?!

  - by A. Miladinovic

  Hello everybody, I am creating an app for the iPhone that fetches a specific page from a website, but to be able to view this site you need to log in with a username and a password. I've created this code: NSString *urlAddress = @"http://www.wdg-hamburg.de"; NSURL *url = [NSURL URLWithString:urlAddress]; NSString *post = @"name=loginname&pass=pass&form_id=user_login&op=Anmelden"; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod: @"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; [vPlan loadRequest:request]; But I am not logged in at the UIWebView! I am logging NSHTTPCookieStorage to the console and it shows me the necessary cookie, but I dont get logged in. Does anybody knows how I can fix that? Kind regards, A. Miladinovic

• How can you add a UIGestureRecognizer to a UIBarButtonItem as in the common undo/redo UIPopoverContr

  - by SG

  Problem In my iPad app, I cannot attach a popover to a button bar item only after press-and-hold events. But this seems to be standard for undo/redo. How do other apps do this? Background I have an undo button (UIBarButtonSystemItemUndo) in the toolbar of my UIKit (iPad) app. When I press the undo button, it fires it's action which is undo:, and that executes correctly. However, the "standard UE convention" for undo/redo on iPad is that pressing undo executes an undo but pressing and holding the button reveals a popover controller where the user selected either "undo" or "redo" until the controller is dismissed. The normal way to attach a popover controller is with presentPopoverFromBarButtonItem:, and I can configure this easily enough. To get this to show only after press-and-hold we have to set a view to respond to "long press" gesture events as in this snippet: UILongPressGestureRecognizer *longPressOnUndoGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPressOnUndoGesture:)]; //Broken because there is no customView in a UIBarButtonSystemItemUndo item [self.undoButtonItem.customView addGestureRecognizer:longPressOnUndoGesture]; [longPressOnUndoGesture release]; With this, after a press-and-hold on the view the method handleLongPressOnUndoGesture: will get called, and within this method I will configure and display the popover for undo/redo. So far, so good. The problem with this is that there is no view to attach to. self.undoButtonItem is a UIButtonBarItem, not a view. Possible solutions 1) [The ideal] Attach the gesture recognizer to the button bar item. It is possible to attach a gesture recognizer to a view, but UIButtonBarItem is not a view. It does have a property for .customView, but that property is nil when the buttonbaritem is a standard system type (in this case it is). 2) Use another view. I could use the UIToolbar but that would require some weird hit-testing and be an all around hack, if even possible in the first place. There is no other alternative view to use that I can think of. 3) Use the customView property. Standard types like UIBarButtonSystemItemUndo have no customView (it is nil). Setting the customView will erase the standard contents which it needs to have. This would amount to re-implementing all the look and function of UIBarButtonSystemItemUndo, again if even possible to do. Question How can I attach a gesture recognizer to this "button"? More specifically, how can I implement the standard press-and-hold-to-show-redo-popover in an iPad app? Ideas? Thank you very much, especially if someone actually has this working in their app (I'm thinking of you, omni) and wants to share...

• viewDidLoad not being called by parent UITabBarController

  - by Adam Bishop

  Sample: I've created a minimal set of files that highlight the issue here: http://uploads.omega.org.uk/Foo3.zip If viewDidLoad/viewInitWithNibName are called, a message box is displayed. The message box is not displayed, therefore, the methods are not being called. Details: I have an application that is attempting to use a UITabBarController to switch between multiple views. The views are linked up to the UITabBarController using interface builder (select the tab page, open Attributes (Option-1), and fill in the NIB Name field), and so are displayed "automatically" with no extra code-behind to make them appear. Is it intended behaviour that views loaded like this do not have their viewDidLoad method executed? If not, how am I doing it wrong, and what do I need to change. If it is intended behaviour, I can think of a few work-arounds, but any suggestions are appreciated: Scrap the UITabBarController and implement the view switching myself (using initWithNibName and add/insert/push/Subview). Call each of the children's viewDidLoad method manually in the UITabBarController's own viewDidLoad method. Thank you in advance for any help you can offer.

• Need content in UIWebView to display quickly

  - by leftspin

  Part of my app caches web pages for offline viewing. To do that, I am saving the HTML fetched from a site and rewriting img urls to point to a file on the local store. When I load the html into a UIWebView, it loads the images as expected and everything's fine. I am also caching stylesheets in this fashion. The problem is that when I put the phone into airplane mode, loading this cached html causes the UIWebView to display a blank screen and pause for a while before displaying the page. I've figured out that it's caused by non-cached URLs referenced from the original HTML doc that the web view is trying to fetch. These other URLs include images within the cached stylesheets, content in iframes, and javascript that opens a connection to fetch other resources. The pause happens when the UIWebView tries to fetch these resources, and the web page only appears after all these other fetches have timed out. My questions is, how can I make UIWebView just display the stuff I've cached immediately? Here are my thoughts: write even more code to cache these other references. This is potentially a ton more code to catch all the edge cases, etc., especially having to parse the Javascript to see what it loads after the page is loaded force UIWebView to time out immediately so there's no pause. I haven't figured out how to do this. somehow get what's already loaded to display even though the external references haven't finished fetching yet strip the code of all scripts, link tags and iframes to "erase" the external references. I've tried this one, but for some sites, the resultant page is severely messed up Can anyone help me here? I've been working on this forever, and am running out of ideas.

• iPod/iPhone OpenGL ES UIView flashes when updating

  - by Dave Viner

  I have a simple iPhone application which uses OpenGL ES (v1) to draw a line based on the touches of the user. In the XCode Simulator, the code works perfectly. However, when I install the app onto an iPod or iPhone, the OpenGL ES view "flashes" when drawing the line. If I disable the line drawing, the flash disappears. By "flash", I mean that the background image (which is an OpenGL texture) disappears momentarily, and then reappears. It appears as if the entire scene is completely erased and redrawn. The code which handles the line drawing is the following: renderLineFromPoint:(CGPoint)start toPoint:(CGPoint)end { static GLfloat* vertexBuffer = NULL; static NSUInteger vertexMax = 64; NSUInteger vertexCount = 0, count, i; //Allocate vertex array buffer if(vertexBuffer == NULL) vertexBuffer = malloc(vertexMax * 2 * sizeof(GLfloat)); //Add points to the buffer so there are drawing points every X pixels count = MAX(ceilf(sqrtf((end.x - start.x) * (end.x - start.x) + (end.y - start.y) * (end.y - start.y)) / kBrushPixelStep), 1); for(i = 0; i < count; ++i) { if(vertexCount == vertexMax) { vertexMax = 2 * vertexMax; vertexBuffer = realloc(vertexBuffer, vertexMax * 2 * sizeof(GLfloat)); } vertexBuffer[2 * vertexCount + 0] = start.x + (end.x - start.x) * ((GLfloat)i / (GLfloat)count); vertexBuffer[2 * vertexCount + 1] = start.y + (end.y - start.y) * ((GLfloat)i / (GLfloat)count); vertexCount += 1; } //Render the vertex array glVertexPointer(2, GL_FLOAT, 0, vertexBuffer); glDrawArrays(GL_POINTS, 0, vertexCount); //Display the buffer [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } (This function is based on the function of the same name from the GLPaint sample application.) For the life of me, I can not figure out why this causes the screen to flash. The line is drawn properly (both in the Simulator and in the iPod). But, the flash makes it unusable. Anyone have ideas on how to prevent the "flash"?

• How to change image and disable UIBarButtonItem

  - by Alex

  I have a NavigationBar app with two views: a parent and a sub view. In the sub view I'm adding a button to the right corner as follows: - (void)viewDidLoad { UIBarButtonItem *tempButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"lock-unlocked.png"] style:UIBarButtonItemStylePlain target:self action:@selector(lockScreen)]; self.navigationItem.rightBarButtonItem = tempButton; [tempButton release]; } When that button is clicked I want to change the image of this rightBarButtonItem and disable the leftBarButtonItem (which was added automatically by the controller). Basically have two states of a button, locked and unlocked. Question 1: The only way I can find how to change the image is to create a new UIButtonItem with a new image and replace rightBarButtonItem with that new one. But I'm wondering if there's a way to just change the image without creating a new UIBarButtonItem. Am I creating a memory leak if I keep creating new UIBarButtonItem? Question 2: How can I get a hold of self.navigationItem.leftBarButtonItem and disable/enable it? I don't create that one manually, it's created automatically for me by the controller. I don't see any method/property on UIBarButtonItem to enable/disable user interaction with it.

• Loop an UIScrollView

  - by Ilya

  Hi, I've got an UIScrollView and in it different images(about 30). I'd like to make it possible, when user reaches the last image to show the first one after it and so on. And I want to implement the same feature with the first image(to go to the last one). I'd like to loop the images smoothly that user won't even notice that he is making another loop. What is the best way to achieve this? Thanks.

• Changing CSS on the fly in a UIWebView on iPhone

  - by Shaggy Frog

  Let's say I'm developing an iPhone app that is a catalogue of cars. The user will choose a car from a list, and I will present a detail view for the car, which will describe things like top speed. The detail view will essentially be a UIWebView that is loading an existing HTML file. Different users will live in different parts of the world, so they will like to see the top speed for the car in whatever units are appropriate for their locale. Let's say there are two such units: SI (km/h) and conventional (mph). Let's also say the user will be able to change the display units by hitting a button on the screen; when that happens, the detail screen should switch to show the relevant units. So far, here's what I've done to try and solve this. The HTML might look something like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US"> <head> <title>Some Car</title> <link rel="stylesheet" media="screen" type="text/css" href="persistent.css" /> <link rel="alternate stylesheet" media="screen" type="text/css" href="si.css" title="si" /> <link rel="alternate stylesheet" media="screen" type="text/css" href="conventional.css" title="conventional" /> <script type="text/javascript" src="switch.js"></script> </head> <body> <h1>Some Car</h1> <div id="si"> <h2>Top Speed: 160 km/h</h2> </div> <div id="conventional"> <h2>Top Speed: 100 mph</h2> </div> </body> The peristent stylesheet, persistent.css: #si { display:none; } #conventional { display:none; } The first alternate stylesheet, si.css: #si { display:inline; } #conventional { display:none; } And the second alternate stylesheet, conventional.css: #si { display:none; } #conventional { display:inline; } Based on a tutorial at A List Apart, my switch.js looks something like this: function disableStyleSheet(title) { var i, a; for (i = 0; (a = document.getElementsByTagName("link")[i]); i++) { if ((a.getAttribute("rel").indexOf("alt") != -1) && (a.getAttribute("title") == title)) { a.disabled = true; } } } function enableStyleSheet(title) { var i, a; for (i = 0; (a = document.getElementsByTagName("link")[i]); i++) { if ((a.getAttribute("rel").indexOf("alt") != -1) && (a.getAttribute("title") == title)) { a.disabled = false; } } } function switchToSiStyleSheet() { disableStyleSheet("conventional"); enableStyleSheet("si"); } function switchToConventionalStyleSheet() { disableStyleSheet("si"); enableStyleSheet("conventional"); } My button action handler looks something like this: - (void)notesButtonAction:(id)sender { static BOOL isUsingSi = YES; if (isUsingSi) { NSString* command = [[NSString alloc] initWithString:@"switchToSiStyleSheet();"]; [self.webView stringByEvaluatingJavaScriptFromString:command]; [command release]; } else { NSString* command = [[NSString alloc] initWithFormat:@"switchToConventionalStyleSheet();"]; [self.webView stringByEvaluatingJavaScriptFromString:command]; [command release]; } isUsingSi = !isUsingSi; } Here's the first problem. The first time the button is hit, the UIWebView doesn't change. The second time it's hit, it looks like the conventional style sheet is loaded. The third time, it switches to the SI style sheet; the fourth time, back to the conventional, and so on. So, basically, only that first button press doesn't seem to do anything. Here's the second problem. I'm not sure how to switch to the correct style sheet upon initial load of the UIWebView. I tried this: - (void)webViewDidFinishLoad:(UIWebView *)webView { NSString* command = [[NSString alloc] initWithString:@"switchToSiStyleSheet();"]; [self.webView stringByEvaluatingJavaScriptFromString:command]; [command release]; } But, like the first button hit, it doesn't seem to do anything. Can anyone help me with these two problems?

• CGContextDrawPDFPage taking up large amounts of memory

  - by Ed Marty

  I have a PDF file that I want to draw in outline form. I want to draw the first several pages on the document each in their own UIImage to use on a button so that when clicked, the main display will navigate to the clicked page. However, CGContextDrawPDFPage seems to be using copious amounts of memory when attempting to draw the page. Even though the image is only supposed to be around 100px tall, the application crashes while drawing one page in particular, which according to Instruments, allocates about 13 MB of memory just for the one page. Here's the code for drawing: //Note: This is always called in a background thread, but the autorelease pool is setup elsewhere + (void) drawPage:(CGPDFPageRef)m_page inRect:(CGRect)rect inContext:(CGContextRef) g { CGPDFBox box = kCGPDFMediaBox; CGAffineTransform t = CGPDFPageGetDrawingTransform(m_page, box, rect, 0,YES); CGRect pageRect = CGPDFPageGetBoxRect(m_page, box); //Start the drawing CGContextSaveGState(g); //Clip to our bounding box CGContextClipToRect(g, pageRect); //Now we have to flip the origin to top-left instead of bottom left //First: flip y-axix CGContextScaleCTM(g, 1, -1); //Second: move origin CGContextTranslateCTM(g, 0, -rect.size.height); //Now apply the transform to draw the page within the rect CGContextConcatCTM(g, t); //Finally, draw the page //The important bit. Commenting out the following line "fixes" the crashing issue. CGContextDrawPDFPage(g, m_page); CGContextRestoreGState(g); } Is there a better way to draw this image that doesn't take up huge amounts of memory?

  I have a library I made, and now I want to utilize it in an application. I've believe I've properly linked to the library.

• Add a sub-view to a DetailView UIView in iPad

  - by Elisabeth

  I'm creating a split view controller app, the detail view has a segmented control in a navigation bar at the top. Clicking on a segment will add a new view to the detail view with the appropriate information on it (covering up the DetailViewController's default UIView). I've created two new UIViews, corresponding to each segment, and I'm trying to add them to the view like this (in DetailViewController.m): if (exerciseSegmentControl.selectedSegmentIndex == UISegmentedControlNoSegment) { NSLog(@"No segment selected"); } UIView *viewToShow; if (selectedView == 0 && exerciseSegmentControl.selectedSegmentIndex == 1) { viewToShow = exerciseSolutionView; } else { viewToShow = exerciseView; } [self.view addSubview:viewToShow]; I see the view appear, but it's in the wrong place, it is placed at the very top of the window, instead of below the navigation bar. In IB, I've created instances of the views, and I've used the Attributes inspector to specify "Navigation Bar" for top bar, which sets the height of the view correctly. But the view is clearly being added too far up in the window - I see the view below it (the DetailViewController's UIView) peaking out at the bottom (I changed the background color so I know which view I'm seeing). Any tips on how to get the subview I'm adding to get placed correctly in the window? Thanks!

• How to follow user location with MapKit

  - by Bloudermilk

  I'm using MapKit to display the user's location relative to pins around them. I'd like to be able to mimic the functionality that Maps provides via the crosshair button in the lower left-hand corner of the screen. I'm already aware that MapKit provides a CLLocation object with the user's location via MKUserLocation, I just wanted to seek advice on how I should keep focus on that location. My initial inclination was to use an NSTimer to center the map on that coordinate every 500ms or so. Is there a better way to do this? Is there something built in to MapKit that I'm missing that will accomplish this? Thanks so much, Brendan

• Memory management for NSURLConnection

  - by eman

  Sorry if this has been asked before, but I'm wondering what the best memory management practice is for NSURLConnection. Apple's sample code uses -[NSURLConnection initWithRequest:delegate:] in one method and then releases in connection:didFailWithError: or connectionDidFinishLoading:, but this spits out a bunch of analyzer warnings and seems sort of dangerous (what if neither of those methods is called?). I've been autoreleasing (using +[NSURLConnection connectionWithRequest:delegate:]), which seems cleaner, but I'm wondering--in this case, is it at ever possible for the NSURLConnection to be released before the connection has closed?

• Installing a configuration profile on iPhone - programmatically

  - by Seva Alekseyev

  Hi all, I would like to ship a configuration profile with my iPhone application, and install it if needed. Mind you, we're talking about a configuration profile, not a provisioning profile. First off, such a task is possible. If you place a config profile on a Web page and click on it from Safari, it will get installed. If you e-mail a profile and click the attachment, it will install as well. "Installed" in this case means "The installation UI is invoked" - but I could not even get that far. So I was working under the theory that initiating a profile installation involves navigating to it as a URL. I added the profile to my app bundle. A) First, I tried [sharedApp openURL] with the file:// URL into my bundle. No such luck - nothing happens. B) I then added an HTML page to my bundle that has a link to the profile, and loaded it into a UIWebView. Clicking on the link does nothing. Loading an identical page from a Web server in Safari, however, works fine - the link is clickable, the profile installs. I provided a UIWebViewDelegate, answering YES to every navigation request - no difference. C) Then I tried to load the same Web page from my bundle in Safari (using [sharedApp openURL] - nothing happens. I guess, Safari cannot see files inside my app bundle. D) Uploading the page and the profile on a Web server is doable, but a pain on the organizational level, not to mention an extra source of failures (what if no 3G coverage? etc.). So my big question is: how do I install a profile programmatically? And the little questions are: what can make a link non-clickable within a UIWebView? Is it possible to load a file:// URL from my bundle in Safari? If not, is there a local location on iPhone where I can place files and Safari can find them? EDIT on B): the problem is somehow in the fact that we're linking to a profile. I renamed it from .mobileconfig to .xml ('cause it's really XML), altered the link. And the link worked in my UIWebView. Renamed it back - same stuff. It looks as if UIWebView is reluctant to do application-wide stuff - since installation of the profile closes the app. I tried telling it that it's OK - by means of UIWebViewDelegate - but that did not convince. Same behavior for mailto: URLs within UIWebView. For mailto: URLs the common technique is to translate them into [openURL] calls, but that doesn't quite work for my case, see scenario A. For itms: URLs, however, UIWebView works as expected... EDIT2: tried feeding a data URL to Safari via [openURL] - does not work, see here: http://stackoverflow.com/questions/641461/iphone-open-data-url-in-safari EDIT3: found a lot of info on how Safari does not support file:// URLs. UIWebView, however, very much does. Also, Safari on the simulator open them just fine. The latter bit is the most frustrating.
