  • Does tableViewController behave incorrectly when hosted by a popoverController?

    - by dugla
    I have made countless test examples of a tableViewController hosted by a popoverController and I have come to the following conclusion: It does not appear possible to pre-select a tableView cell. It is possible to do pre-selection when a tableViewController is hosted by a splitviewController. I am using the exact same tableViewController code. Here is the relevant tableViewController view lifecycle method that is misbehaving: static BOOL firstTime = YES; - (void)viewDidAppear:(BOOL)animated { NSLog(@"Root ViewController - view Did Appear"); [super viewDidAppear:animated]; if (firstTime == YES) { firstTime = NO; NSIndexPath *preselectedCell = [NSIndexPath indexPathForRow:5 inSection:0]; [self.tableView selectRowAtIndexPath:preselectedCell animated:NO scrollPosition:UITableViewScrollPositionTop]; detailViewController.detailItem = [NSString stringWithFormat:@"Row %d", preselectedCell.row]; } // if (firstTime == YES) } The above code correctly preselects a tableView cell the first time the tableView is unfurled in the splitViewController case (device in portrait mode). Can someone please, please, explain what I am doing wrong. I am completely stumped. Thanks, Doug

  • Paging a UIScrollView with a large PDF

    - by Fousa
    I try to create a simple UIScrollView with paging. And I want to be able to scroll through a large PDF document, but this gives me some problems... I tried the following options: Convert all the PDF pages to UIImages at startup, this works, but is very slow on start Manually drawing the PDF page in the drawRect, but yet again this was slow... And I prefer not to load everything at startup but to do it during the usage. Did anyone did this recently? Can't seem to find a nice example project. Thnx! Jelle

  • iphone/ipad with 2 side by side tables

    - by jesse001
    I want to create a view with 2 tables side by side, where selecting the row on 1 table effects the content of the other and vice versa (not parent child). My problem is how to send the request. I started with a utility app using core data, and added 2 table view controllers. I added these to the main view nib and moved the tables to the view. One table controls a list from Core Data, then on selecting a row I want it to move to the other table which is based on a mutable array. On didselectrow I want to tell the other table to update, however I can only find samples that are parent/child so involves initializing. Does anyone know of a way to do this for an active view? Thanks heaps for your help.

  • What alternatives do I have for source control and does GIT does that?

    - by RubberDuck
    I work as a freelancer programmer for some clients and also create apps for myself. When I work for myself, obviously I work alone. I generally don't work in a linear way. My big problems today are: I have a lot of apps that use the same classes I have developed; In the past, I put all these common classes on a directory outside all projects and included them on my apps using absolute paths, but this method sucks because by accident (if you forget) you may change a path or the disk and all projects are broken. Then I decided to copy those classes to my projects every time. Because the majority of these classes do not change frequently, I am relatively ok, but when they change, I am in hell; When I change one of these classes I have to propagate the changes to all other apps using copies of them. I have also tried to create frameworks but thanks to Apple, I cannot create frameworks for iOS and have to create libraries and bundles and create a nightmare of paths from one to the other and to the project to make that sh!t works. So, I am done with frameworks/libraries on Xcode until Xcode is a decent IDE. So, I see I need something better to manage my source code. What I need is this (I never used GIT on Xcode. I have read Apple docs but I still have these points): does git locally on Xcode allows me to deal with assets or just code? Can I have the equivalent of a "framework" (code + assets) managed by git locally? Can an entire xcodeproj be managed as a unity? I mean, Suppose I have a xcodeproj created and want GIT to manage it. How do I enable git on a project that was created without it and start designating files for management. (I have enabled git on Xcode's preferences, but all source control menu is grayed out). Is git the best option? Do I have another? Remember that my main condition is that the files should stay on the local computer. Please save me (I am a bit dramatic today). Thanks.

  • ivar is inside two blocks

    - by Desperate Developer
    I have an ivar like this declared on interface: BOOL controllerOK; I have to use this ivar inside a block that resides itself in a block. Something like myBlockl = ^(){ [self presentViewController:controller animated:YES completion:^(){ if (controllerOK) [self doStuff]; }]; }; If I try to do that, I see an error capturing self strongly in this block is likely to lead to a retain cycle for the if (controllerOK) line. This does not appear to be one of those blocks problems that you create another variable using __unsafe_unretained before the block starts. First because this instruction cannot be used with a BOOL and second because the ivar controllerOK has to be tested on runtime inside the block. Another problem is that the block itself is declared on the interface, so it will be used outside the context where it is being created. How do I solve that?

  • iphone view controller class - how to

    - by Brodie4598
    Hello - I need to create my own UIView class and it is not something I have had to do. I created the class, then laid out the small view in IB (it's just a few labels that i will later need to add data to ). but now im stuck on how to actually put an instance of it in my main view. Can someone point me in the direction of a good tutorial? The closest thing I have done to this is creating a custom tableViewCell. DataTagViewController *dataTag = [[DataTagViewController alloc]init]; [theMap addSubView: dataTag];

  • PDF search on the iPhone

    - by pt2ph8
    After two days trying to read annotations from a PDF using Quartz, I've managed to do it and posted my code. Now I'd like to do the same for another frequently asked question: searching PDF documents with Quartz. Same situation as before, this question has been asked many times with almost no practical answers. So I need some pointers first, as I still haven't implemented this myself. What I tried: I tried using CGPDFScannerScan handling the TJ and Tj operators - returns the right text on some PDF, whereas on other documents it returns mostly random letters. Maybe it's related to text encoding? Someone pointed out that text blocks (marked by BT/ET operators) should be handled instead, but I still haven't managed to do so. Anyone managed to extract text from any PDF? After that, searching should be easy by storing all the text in a NSMutableString and using rangeOfString (if there's a better way please let me know). But then how to highlight the result? I know there are a few operators to find the glyph sizes, so I could calculate the resulting rect based on those values, but I've been reading the spec for hours... it's a bloated mess and I'm going insane. Anyone with a practical explanation? Thanks.

  • Correct way to switch between UIView with ARC. My way leads to memory leaks :( (iOS)

    - by Andrei Golubev
    i use xcode 4.4 with ARC on.. I have dynamically created UIViews in the ViewController.m: UIView*myviews[10]; Then in the - (void)viewDidLoad function i fill each of it with pictures i need myviews[viewIndex] = [[UIView alloc]initWithFrame:myrec]; UIImage *testImg; UIImageView * testImgView; testImg = [UIImage imageNamed:[NSString stringWithFormat:@"imgarray%d.png", viewIndex]; testImgView.image = testImg; viewindex++; So all seems to be fine, when i want to jump from one view to another i do with two buttons next: [self.view addSubview:views[viewIndex]]; CATransition *animation = [CATransition animation]; [animation setDelegate:self]; [animation setDuration:1.0f]; [animation setType:@"rippleEffect"]; [animation setSubtype:kCATransitionFromTop]; //[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; [self.view.layer addAnimation:animation forKey:@"transitionViewAnimation"]; Nothing seems to be bad, but the memory consumption grows with huge speed when i switch between views.. and then i get low memory warning or sometimes application will just crash. I have tried to use UIViewController array and was switching between the controllers: nothing changes, the memory low warning is what i end up with.. Maybe i need to clean the memory somehow? But how? ARC does not allow to use release and so on.. last what i have tried (sorry, maybe not very professional) before to add new subview is this NSArray *viewsToRemove = [self.view subviews]; for (UIView *views in viewsToRemove) { [views removeFromSuperview]; } But this does not help either.. Please don't judge too strong, i am still new to iOS and Objective-c..

  • UIView capturing all events

    - by Josh P.
    I have a UIView that uses several UIGestureRecognizers and this view again has at least one child view that contains a MPMoviePlayerController. When a touch event occurs over the movie player, the main view seems to 'eat' all the events, leaving the media player idle. How can I make sure that the events are delivered correctly to the player?

  • Replace an Array with an Array

    - by Dane Man
    I have and NSMutableArray and I want to replace it with another, but if I try to do it like this... firstArray = secondArray; ...then it seems to erase the entire firstArray and I get this error message.. Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)' ...and the bounds should be (6) not (0). Is there a correct way to replace the array? PS: I already checked the secondArray and it functions fine.

  • Having an issue while trying to implement In-App Purchase

    - by Raymond
    This is my first time to implement In-App purchase and I am using the tutorial located here: Ray Wenderlich Now I am sure this is something simple, but I am having issues figuring out, so I figured I would ask all of the gurus out here. The compiler is saying that _products is Use of undeclared identifier - (void)productPurchased:(NSNotification *)notification { NSString * productIdentifier = notification.object; [_products enumerateObjectsUsingBlock:^(SKProduct * product, NSUInteger idx, BOOL *stop) { if ([product.productIdentifier isEqualToString:productIdentifier]) { *stop = YES; } }]; }

  • Adding a view with a view controller as a subview of another view controller. Doesn't work.

    - by Tom
    I'm trying to essentially re-implement the UISplitViewController (because it has its limits), but when I create a UIViewController viewController, and then do an "[viewController.view addSubview contentViewController.view]" on it, to add a view that already has a view controller, that content view doesn't seem to get initialised by its view controller. I guess its view controller is getting detached or deallocated, is this the case?

  • UIButton not getting touch events inside a custom UITableViewCell

    - by user210504
    Hi! I have designed a custom UItableView Cell in IB. This cell has a UIButton with an associated action. This button is not getting touch events, however the cell itself gets the events when called. What could I be doing wrong here. +--------------------------------+ | +----------+ | Cell | Button | | +----------+ +--------------------------------+ When I tap on the Button tableviewcell gets the events. What could be wrong? EDIT: I just checked, that UIButton is also getting touch events, but so is the UITableViewCell. And at then end of it the action associated with UIButton is not getting called.

  • How to quickly access documentation in Xcode 4.5.1?

    - by International Frog
    How can I quickly access the documentation for a symbol, method, enum, etc. in Xcode 4.5? alt + click on symbol shows a quick-info. Apple removed the dictionary icon which opened the documentation. I tried all other possible shortcuts of the cmd / alt / shift / click mumbo jumbo dance and none of them open the documentation browser. I suppose there is a hidden trick to quickly open it anyways? Edit: Figured out this new quick-info box has a link to the documentation.
