  • selecting a row by means of a button ... using didSelectRowAtIndexPath

    - by John Smith
    hey people , I have a question concerning a button I would like to create which selects my previous selected row. This is what I came up so far but since I'm new with the functionality and such I could definately use some pointers I created a toolbar with a button and behind this button is the following action. -(void)clickRow { selectedRow = [self.tableView indexPathForSelectedRow]; [self.tableView:[self tableView] didSelectRowAtIndexPath:selectedRow]; } in my didSelectRowAtIndexPath there is a rootViewController being pushed rvController = [RootViewController alloc] ...etc So what I would like is my function clickRow to select the row and push the new rootviewcontroller (which has the right info since I'm using a tree ). I tried something like this as well -(void)clickRow { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; NSArray *Children = [dictionary objectForKey:@"Children"]; rvController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; rvController.CurrentLevel += 1; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } The last function works a little but a little is not enough;) For instance if I press the middle row or any other it constantly selects the toprow. thnx all for those of you reading and trying to help

  • What can cause Bonjour to not call me back during browsing?

    - by millenomi
    I have a rather popular Bonjour-based application in App Store. It works perfectly, but around 0.2% of my users report a bizarre bug: "no arrows appear on the edges of the screen, so I can't share stuff with other people!". Needless to say, displaying these arrows is tied to the browsing of a particular Bonjour service on the local domain. The problem is, the Apple review team seems to intermittently happen to be in this 0.2%. This isn't good for review results, as you might imagine. No matter how much I try, I cannot reproduce this bug. From the few logs I have, it looks like my app is running correctly, just not receiving NSNetServiceBrowser delegate calls. What can cause this? Things I've tried: Having a shorter service name < 14 chars in length to be in spec. Publishing on @"local." rather than @"" (aka Go Look For The Default Registration Domain). My app is rather useless on a wide-area network anyway. Things I haven't tried: restarting the browsing machinery periodically. (I have two browsers, though, one looking for the legacy longer name, one for the new shorter one.) What to do?

  • Twitter and Facebook status in

    - by Chris S
    Are there any C# libraries for integrating Facebook status updates and twitter updates (preferably with url shortening) in Monotouch without too much heavy lifting? I know there is a Facebook kit already for objective-C, I really only need status updating however.

  • UTF-8 conversion

    - by leachianus
    Hey guys, I am grabbing a JSON array and storing it in a NSArray, however it includes JSON encoded UTF-8 strings, for example pass\u00e9 represents passé. I need a way of converting all of these different types of strings into the actual character. I have an entire NSArray to convert. Or I can convert it when it is being displayed, which ever is easiest. I found this chart http://tntluoma.com/sidebars/codes/ is there a convenience method for this or a library I can download? thanks, BTW, there is no way I can find to change the server so I can only fix it on my end...

  • UIWebView in multithread ViewController

    - by Tao
    I have a UIWebView in a viewcontroller, which has two methods as below. The question is if I pop out(tap back on navigation bar) this controller before the second thread is done, the app will crash after [super dealloc], because "Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread.". Any help would be really appreciated. -(void)viewDidAppear:(BOOL)animated { [super viewWillAppear:animated]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(load) object:nil]; [operationQueue addOperation:operation]; [operation release]; } -(void)load { [NSThread sleepForTimeInterval:5]; [self performSelectorOnMainThread:@selector(done) withObject:nil waitUntilDone:NO]; }

  • Where to #include?

    - by fuzzygoat
    In my past applications I have been #importing into my *.h files where needed. I have not really thought much about this before as I have not had any problems, but today I spotted something that got me to thinking that maybe I should be #import-ing into my .m files and using @class where needed in the headers (.h) Can anyone shine any light on the way its supposed to be done or best practice? gary

  • How do I switch between Navigation Controllers?

    - by RexOnRoids
    Situation: I have an Xcode project based on the "Navigation-Based-Application" template. So that means I have a SINGLE UINavigationController that manages a UIViewController. What I want To Do: What I want to do is add one more UINavigationController to my project -- and be able to switch back and forth between them. (I want to do this to make space for some seperate unrelated content so that it does not have a back button pointing back to the root view controller.) Question: How do I add one more UINavigationController to my project and switch between the two UINavigationControllers?

  • Bug in UITableView: Why is the section header covered by an row after deleting an row?

    - by mystify
    When I delete a row like this, and then scroll a little bit, one of the rows of that section happens to cover the section header. - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [dataManager deleteValueAtIndex:indexPath.row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; } } Is there any solution to this?

  • In-app subscription apps

    - by Ron Srebro
    Does anyone know of an app that implemented an in-app subscription? I thought about how the subscription model can be implemented and always ends up with more problems to every possible solution I can think of, so I'm wondering if anyone knows of an app that actually does that. Thanks

  • Running out of memory but not seeing excessive object allocation in Instruments

    - by Scotty Allen
    I have an iPad app that's crashing due to low memory. However, Instruments doesn't show any significant amount of memory allocated using ObjectAlloc - it stays under 1MB for the lifetime of the application. Leaks shows less than 1kB leaked over the course of the run. Memory monitor shows the free memory on the devices drop significantly with use, eventually dropping to the point that it's out of memory. Here's a screenshot from Instruments: I'm totally stumped. As far as I can tell, this basically says that as far as my app is concerned, I'm never using more than about 750kB, but that the device is still running out of physical memory, which is causing my app to crash/force exit. I'm new to debugging memory issues with XCode. Am I measuring this wrong? Is there another way to see where this memory is going?

  • UITableViewIndex Grows to Incorrect Bounds Unexpectedly

    - by chadburggraf
    I have a standard UITableView + UISearchDisplayController + UITableViewIndex setup. Everything works like a champ. Except, under very specific conditions, the index grows too long to display on the screen. Specifically, after ending a search and re-displaying the unfiltered, indexed table, the index sometimes grows too long. More specifically, this doesn't happen if I search then cancel. It only happens if I search, then push a view controller from the search table, then pop that view controller back to the still-searching table, then cancel the search, then re-search and then cancel that final search. After the end of the final search the index is too long. In portrait, the table view is reporting a height of 416 and the index a height of 404 under normal conditions. If I log from searchDisplayControllerDidEndSearch when the index is sized incorrectly, it is reporting a height of 620. I've tried everything from setLayout on the table and the index to manually re-sizing the frame. Nothing works (the manual re-size causes the correct height to be logged, but it doesn't change the display on screen). I was about to try re-sizing after a delay in case the cancel animation was interfering, but then I realized what an absurd situation I'm in and thought seeking help might be wise...

  • How Do I create a synchronous version of NSURLConnection

    - by quinn
    I am using NSURLConnection inside of an NSIncrementalStore to synchronize my NSManagedObject with rest based web service built in Rails. I am aware of +sendSynchronousRequest:returningResponse:error but my understanding is that will not allow me to access such things as the HTTP response status code which I will need to properly handle the response, my understanding is sendSynchronousRequest returns the data if it responds in the 200 range and fails if it doesn't and doesn't really give you much more than that. I'm assuming I will somehow have to block the current method call after the NSURLConnection is instantiated and unblock it after NSURLConnection's delegate sets some value that can be returned by the blocked method. I'm assuming this will involve some combination of NSLock and NSThread but I really don't know where to start with this, any help will be greatly appreciated, thank you.

  • How to properly set relationships in Core Data when using setValue and data already exists

    - by ern
    Let's say I have two objects: Articles and Categories. For the sake of this example all relevant categories have already been added to the data store. When looping through data that holds edits for articles, there is category relationship information that needs to be saved. I was planning on using the -setValue method in the Article class in order to set the relationships like so: - (void)setValue:(id)value forUndefinedKey:(NSString *)key { if([key isEqualToString:@"categories"]){ NSLog(@"trying to set categories..."); } } The problem is that value isn't a Category, it is just a string (or array of strings) holding the title of a category. I could certainly do a lookup within this method for each category and assign it, but that seems inefficient when processing a whole bunch of articles at once. Another option is to populate an array of all possible categories and just filter, but my question is where to store that array? Should it be a class method on Article? Is there a way to pass in additional data to the -setValue method? Is there another, better option for setting the relationship I'm not thinking of? Thanks for your help.

  • Add blank cell at end of UITable

    - by Michael
    I'm trying to add an additional cell for custom content as the last cell in a tableView, without altering the dictionary that creates the other content of the table. I think the place to add it is in cellForRowAtIndexPath rather than adding one to the numberOfRowsInSection, which just crashes if I do. I get a cellCount from the dictionary that creates the data for the table, then in cellForRowAtIndexPath, I have: if (indexPath.row == cellCount) { ... stuff goes here return cell; } of course, this never gets called. If I do if (indexPath.row == cellCount -1) it overwrites the last cell with content. I can get this to work if I add a blank entry into the xml from which I am populating the dictionary, but that's ugly. Example code would be neat!

  • Convert NSString to fetch synthesized information.

    - by Max
    //COPY THIS CODE IN A FRESH PROJECT!!! //THIS 2 LINES ARE JUST EXAMPLES, IN REAL THEY ARE NOT STATIC! NSString *messagelevel1 = @"45"; NSString *messagelevel = @"1"; NSString *HuidigLevel = messagelevel; NSDecimalNumber *huidigleveldec = [[NSDecimalNumber alloc] initWithString: HuidigLevel]; float HuidigLevelRek = [huidigleveldec floatValue]; //HERE IS THE PROBLEM NSString* LevelTotaal=[[NSString alloc] initWithFormat:@"messagelevel%.f",HuidigLevelRek]; NSString*result = LevelTotaal; NSLog(@"%@",result); // THIS RESULT SHOULD RETURN THE SAME VALUE AS THE LINE UNDER THIS LINE! NSLog(@"%@",messagelevel1); I want the *result string behaves like the *huidiglevel string and fetch some information, but because the LevelTotaal is a NSString, It doesn't fetch this information. I really got no idea where to google for this problem, searching the Developer docs didn't helped either . Maybe you guys can help me out? Actually the second NSLog returns the value and to first NSLog just returns messagelevel1. To tell you in short ;) I hope you guys get what I'm saying!

  • Removing UITextField from superview does not make it disappear on screen

    - by moshy
    I have the following code // Breakpoint here [label removeFromSuperview]; [label release]; label = nil; stepping through it with the debugger outputs (gdb) po [self subviews] <NSCFArray 0x476af70>( <UIImageView: 0x47581a0; frame = (0 0; 232 81); opaque = NO; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b3d0>>, <UILabel: 0x4758870; frame = (15 11; 202 56); text = 'Test'; clipsToBounds = YES; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b590>> ) (gdb) po label <UILabel: 0x4758870; frame = (15 11; 202 56); text = 'Test'; clipsToBounds = YES; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b590>> (gdb) n (gdb) n (gdb) n (gdb) po [self subviews] <NSCFArray 0x478c4e0>( <UIImageView: 0x47581a0; frame = (0 0; 232 81); opaque = NO; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b3d0>> ) Yet it is still visible, it does not disappear. Not even if I do [self setNeedsDisplay] immediately after. Has anyone else come across this? Is it a bug in the SDK or am I missing something?

  • Proper way to resignFirstResponder when a UITableView is touched?

    - by Topher Fangio
    Hello all, I have a pretty simple UITableView who's cells contain UITextFields and I need to be able to call resignFirstResponder to hide the keyboard whenever a user touches the UITableView outside of one of the cells. I have read this question/answer but it seems like a very rudimentary way to achieve this. I have read about a way to do it by converting the UITableView to a UIControl so that you can connect the TouchDown event. Does anybody know the standard or preferred way to achieve this functionality?
