  • Cocoa-Created PDF Not Rendering Correctly

    - by Matthew Roberts
    I've created a PDF on the iPad, but the problem is when you have a line of text greater than 1 line, the content just goes off the page. This is my code: void CreatePDFFile (CGRect pageRect, const char *filename) { CGContextRef pdfContext; CFStringRef path; CFURLRef url; CFMutableDictionaryRef myDictionary = NULL; path = CFStringCreateWithCString (NULL, filename, kCFStringEncodingUTF8); url = CFURLCreateWithFileSystemPath (NULL, path, kCFURLPOSIXPathStyle, 0); CFRelease (path); myDictionary = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); NSString *foos = @"Title"; const char *text = [foos UTF8String]; CFDictionarySetValue(myDictionary, kCGPDFContextTitle, CFSTR(text)); CFDictionarySetValue(myDictionary, kCGPDFContextCreator, CFSTR("Author")); pdfContext = CGPDFContextCreateWithURL (url, &pageRect, myDictionary); CFRelease(myDictionary); CFRelease(url); CGContextBeginPage (pdfContext, &pageRect); CGContextSelectFont (pdfContext, "Helvetica", 12, kCGEncodingMacRoman); CGContextSetTextDrawingMode (pdfContext, kCGTextFill); CGContextSetRGBFillColor (pdfContext, 0, 0, 0, 1); NSString *body = @"text goes here"; const char *text = [body UTF8String]; CGContextShowTextAtPoint (pdfContext, 30, 750, text, strlen(text)); CGContextEndPage (pdfContext); CGContextRelease (pdfContext);} Now the issue lies within me writing the text to the page, but the problem is that I can't seem to specify a multi-line "text view".

  • How can I change the animation style of a modal UIViewController?

    - by MrDatabase
    I'm currently displaying a UIViewController like this: [[self navigationController] presentModalViewController:modalViewController animated:YES]; and hiding it like this: [self.navigationController dismissModalViewControllerAnimated:YES]; The animation is "slide up from the bottom"... then slide back down.

  • UIView animation doesn't work first time

    - by BobC
    Hello everybody, I have a seachButton in the navigation bar which upon hitting calls following method: - (IBAction)search:(id)sender { if (nil == searchViewController) searchViewController = [[SearchViewController alloc] initWithNibName:@"SearchViewController" bundle:nil]; searchViewController.view.backgroundColor = [UIColor clearColor]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:searchViewController.view cache:NO]; [self.view addSubview:searchViewController.view]; [UIView commitAnimations]; } It should load SearchViewController.xib which contains a view with UISearchBar and two buttons. When I call the search method for the first time, the view appears very quickly with some weird animation, when I call it again, the animation is alright. Does anyone have a clue what could be wrong?

  • Preserving alpha issues with loaded UIImages - how to avoid discarding alpha values on import?

    - by Peter Hajas
    My application lets the user save/load images with alpha values to the camera roll on the device. I can see in the Photos application that these images are appropriately alpha'd, as alpha'd areas just appear black. However, when I load these images back into the application using the valueForKey:UIImagePickerControllerOriginalImage message to the info dictionary from (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info, the alpha values are turned to just white, making those sections opaque. Is there a way to preserve these alpha values?

  • How do you do a foursquare style uitableview refresh?

    - by nickthedude
    If you haven't seen their implementation Of the refresh of a tableview it is extremely slick. I was surprised to see no search results asking for this to be explained so I figured ask it myself. If you haven't seen it, it basically adds a subviews to the uitableview above the header to the blank part of the screen when you pull a uitableview view down farther than it has data to display. Sorry if that doesn't make sense but just download the app and you will immediately want to do it too. Just wondering how they did it?

  • NSAlert pops up for 3 times

    - by Marco
    Hello community i have a big problem. i implemented an NSAlert in the viewDidLoad() of my app: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:alertMessage delegate:self cancelButtonTitle:ok otherButtonTitles:nil]; But the Alert pops up for 3 times, and then i can klick on it. Could it be that the viewDidLoad() starts for 3 times? This is the viewDidLoad in the rootViewController, that manages the views: - (void)viewDidLoad { Kundenkarte *kartenAnsicht = [[Kundenkarte alloc] initWithNibName:@"Kundenkarte" bundle:nil]; kartenAnsicht.rootViewController = self; kartenAnsicht.viewDidLoad; self.map = kartenAnsicht; [self.view addSubview:kartenAnsicht.view]; [kartenAnsicht release]; // [super viewDidLoad]; } kartenAnsicht is the view where the problem is. I hope someone could help me because my ideas are over!

  • Apple's Sample App TopSongs has 26 Leaks, Ugh!

    - by RoLYroLLs
    Hey all, I've been building an app for a client and part of it uses Apple's TopSongs sample app to download data on another thread. I finally got enough done to start testing that part and found 1000 leaks!!! A closer look at the leaks made me check TopSongs for leaks, since none of the my methods were in leaks report. Running TopSongs returned 26 leaks. Not quite sure how to fix them, or if they are part of some library from Apple. I bet you're asking if it has 26, why do you have 1000? Well, I use their sample to make roughly 48 calls to webservices to get all the information needed on initial install (48 calls x 26 leaks = 1248 leaks!!). Later it makes at least 12 calls + 4 to check for updated information on other sections of the app. Can't do a thing about it, can't make one call, or less calls, please don't comment about this part. I seen people respond to posts that aren't necessarily answering the question the user originally posted, which in this case is has anyone tried patching up the leaks, if they are patchable, or is this a bug in Apple's libraries? Thanks so much.

  • Allow swipe-to-delete in one instance of UITableViewDataSource, but not another

    - by synic
    I've got a UITableViewDataSource that I'm using for two different UITableViews. In one of the table views, I want to enable swipe-to-delete, so I've implemented tableView:commitEditingStyle:forRowAtIndexPath, and it works as expected. However, in another table, I want to disable that feature. I've got it working by making two UITableViewDataSource classes, one subclassing the other, and I only implement tableView:commitEditingStyle:forRowAtIndexPath in the subclass. I call them RecipientModel and RecipientModelEditable. I'm wondering if there's a better way.

  • Why won't my CATiledLayer scroll in a UIScrollView after zooming?

    - by Brodie4598
    I'm currently having the following problem with CATiledLayer: when the view first loads, the scrolling works perfectly, but then when you zoom once, the view snaps to the anchor point (top left corner) and it can no longer scroll at all. The zooming works in that it will zoom in and out, but it will only zoom to the top left corner. My code is as follows: #import <QuartzCore/QuartzCore.h> #import "PracticeViewController.h" @implementation practiceViewController //@synthesize image; - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, image.size.width, image.size.height); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.anchorPoint = CGPointMake(0.0f, 1.0f); tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1000, 1000); tiledLayer.levelsOfDetail = 6; tiledLayer.levelsOfDetailBias = 0; tiledLayer.bounds = pageRect; tiledLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 0.3f); myContentView = [[UIView alloc] initWithFrame:self.view.bounds]; [myContentView.layer addSublayer:tiledLayer]; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.minimumZoomScale = .2; scrollView.maximumZoomScale = 1; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect imageRect = CGRectMake (0.0, 0.0, image.size.width, image.size.height); CGContextDrawImage (ctx, imageRect, [image CGImage]); } @end

  • Why would a UIDatePicker with no functionality, added to my app via IB, cause my app to crash?

    - by BeachRunnerJoe
    I just added a UIDatePicker to my iPad app using IB, linked it to its outlet in the code, saved it in IB, added the UIPickerViewDelegate to my UIViewController in the code, as well as added the UIDatePicker outlet in code. When I build and run, the app launches, but will crash intermittently when I attempt to open the popover view that contains the datepicker. I say intermittently because the popover view will occasionally open successfully, but never more than once (it always crashes the second time you open the popover, if it doesn't crash the first time). Also, in the console, I get the following messsage objc[594]: FREED(id): message lastClickRow sent to freed object=0x6015a70 Why is this happening and how can I fix it? What does that console message indicate? It may be worth mentioning that the popover view also contains a table view along with the datepicker control. Thanks so much in advance for your help!

  • Problem generating APN SSL certificate after submitting to apple store

    - by MikeQ
    I'm having trouble getting Apple to generate an APN SSL certificate for my app ID. I've submitted the application to the Apple store, and it is pending review. I tested the application using an Ad Hoc app ID "${bundle_id}.adHoc" and everything went fine. I submitted to the Apple store with app ID "${bundle_id}.release". Now I want to generate my production APN SSL certificate for use with my release application ID - but the developer portal doesn't want to. When I upload my certificate request, it sits for about a minute before telling me: "We are not able to generate your Profile at this time. Please try again later or try using the Provisioning Portal" Is it impossible to generate your certificate while the application is under review or something? Should I have generated it prior to submission?

  • NSInvocationOperation and main thread

    - by kpower
    Imagine that I have a view with some UIKit object as its subview (for example, UIActivityIndicatorView - this doesn't matter). This view also has a selector, called doSomething, which somehow manages UIKit object (in our example it can start or stop indicator view). I create NSInvocationOperation (from view's code parts) with initWithTarget:self selector:@selector(doSomething) object:nil. Then add it to NSOperationQueue. And all works fine. How?! It should be a new thread and non-thread-safe UIKit object! Why no error found (and no crash happened)?

  • Can't set background colour for UIView from ViewController

    - by Curyous
    I have the following code in the view controller: - (void)viewDidLoad { [super viewDidLoad]; ThemeManager *themer = [ThemeManager sharedInstance]; UIView *theView = self.view; UIColor *forBackground = [themer backgroundColour]; [theView setBackgroundColor:forBackground]; } but when execution gets to the setBackgroundColor line, I get the following error: *** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40' There's got to be something simple that I'm doing wrong, how do I set the background colour? Do I have to subclass the view and do it in there? I'd prefer not to have the extra class, even though that is better separation of the whole model/view/controller thing. Update: value returned by [themer backgroundColour] is constructed using colorWithPatternImage:, could this make a difference?

  • How to prevent a modal UIImagePickerController from rotating?

    - by coneybeare
    I have an app that fully support rotation. I am modally adding a UIImagePickerController for which there is no support for UIInterfaceOrientationLandscape and I cannot get the controller to stay in portrait. In other words, I need to disable rotation for the UIImagePickerController so it stays in portrait, without removing rotation for the rest of my app. this seems basic, but I can't seem to locate it. How can I prevent this rotation? UPDATE As suggested, I tried subclassing with the following code: @interface UAImagePickerController : UIImagePickerController { } @end @implementation UAImagePickerController - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation { return UIDeviceOrientationIsPortrait(toInterfaceOrientation); } @end The line is not being hit at all with a breakpoint… i think there must be something funky about the UIImagePickerView

I couldn't find a container or grouping element in IB, so is there a way to move all the Views at once? Thank you in advance and sorry for my english!

  • How to observer when a UIAlertView is displayed?

    - by DotSlashSlash
    Is it anyway possible to observe if a UIAlertView is being displayed and call a function when it is. The UIAlertView is not being created and displayed in the same class which I want a function to be called in. Its hard to explain but to put it simply I need to somehow monitor or observe if the view becomes like out of first responder or something because I dont think it is possible to monitor if a UIAlertView is being displayed :/
