• iPhone XMLParser help

  - by Brodie4598

  I am needing to parse an XML file for my app and I dont have any clue how to do it. I went through one XMLParser tutorial, and it worked fine but the XML file in the tutorial was very simple and my XML file is quite a bit more complex. here is a snippet of the xml file: <?xml version="1.0" encoding="UTF-8"?> <digital_tpp cycle="1003" from_edate="0901Z 03/11/10" to_edate="0901Z 04/08/10"> <state_code ID="AK" state_fullname="Alaska"> <city_name ID="ADAK ISLAND" volume="AK-1"> <airport_name ID="ADAK" military="N" apt_ident="ADK" icao_ident="PADK" alnum="1244"> <record> <chartseq>10100</chartseq> <chart_code>MIN</chart_code> <chart_name>TAKE-OFF MINIMUMS</chart_name> <useraction></useraction> <pdf_name>AKTO.PDF</pdf_name> <cn_flg>N</cn_flg> <cnsection></cnsection> <cnpage></cnpage> <bvsection>C</bvsection> <bvpage></bvpage> <procuid></procuid> <two_colored>N</two_colored> <civil> </civil> <faanfd15></faanfd15> <faanfd18></faanfd18> <copter></copter> </record> <record> <chartseq>10200</chartseq> <chart_code>MIN</chart_code> <chart_name>ALTERNATE MINIMUMS</chart_name> <useraction></useraction> <pdf_name>AKALT.PDF</pdf_name> <cn_flg>N</cn_flg> <cnsection></cnsection> <cnpage></cnpage> <bvsection>E</bvsection> <bvpage></bvpage> <procuid></procuid> <two_colored>N</two_colored> <civil> </civil> <faanfd15></faanfd15> <faanfd18></faanfd18> <copter></copter> </record> </airport_name> </city_name> </state_code> </digital_tpp> What I'm needing to do is search the XML file for the <...icao_ident> that the user specifies, then create a dictionary containing the <pdf_name> and <chart_name> for each <record> . I will then create a UI that displays the pdf files. Can someone direct me to a good tutorial or explanation of how XML parser works? Or if I'm going about this the wrong way I'd be open to suggestions too. (the XML file is about 8MB)

• Implementing Autocompletion in iPhone UITextField for contacts in address book

  - by nacho4d

  Hi, I would like to have a UITextField or UITextView in where as I do some input, alternatives will appear something similar to when you type an address in Mail Application, alternatives appear down and is possible tap them so get a better input user interface.(since there is no need to type the complete word or address or phone number) I do know how to fetch data from Address Book framework, also how to input text in UITextField/UITextView and its delegates but I don't know what kind of structure to use for fetching and showing data as the user do his/her input. I know basic CoreData if this matters, I hope I can get some help. UPDATE (2010/3/10): I don't have problem make a native-like GUI but I am asking about the algorithm, does any body knows what kind algorithm is best for this thing? maybe some binary tree? Or should I just fetch data from coredata everytime? Thanks Ignacio UPDATE (2010/03/28): I've been very busy these days, so I have not tried UISearchResults but it seems fine to me. BUT I wonder was there a necessity of deletion of the wining answer? I don't think is fair my reputation went down and couldn't see the winning answer. ;(

• Hiding UITabBar when rotating device iPhone

  - by Tom G

  Has anyone successfully hidden a UITabbar when rotating the device? I have one view in the UItabbar controller that i rotate (So effectively one tab that rotates) When this happens i want the tab bar to disappear... but nothing seems to work! Either the tabbar still remains visible Or it disappears along with the view Or the tabbar disappears and the view no longer rotates! So if anyone has successfully accomplished this task any advice would be greatly appreciated! Thanks Tom

• MPMoviePlayerContentPreloadDidFinishNotification does not fire [iPhone]

  - by JOKe

  I'm running into a problem with the MPMoviePlayerContentPreloadDidFinishNotification notification. I've regisered to recieve the MPMoviePlayerContentPreloadDidFinishNotification notification and MPMoviePlayerPlaybackDidFinishNotification but the first one never fires. Is this bug in Firmware OS 3.0 ? maybe fixed in 3.1 ? or ? Because my divice and similator is 3.0 maybe this is a bug ? My code : ... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(MovieDidLoad:) name:MPMoviePlayerContentPreloadDidFinishNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(MovieDidLoad:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; ... -(void)MovieDidLoad:(NSNotification*)notification { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Notification Listener" message:@"Notification Listener invoked" cancelButtonTitle:@"Ok dude!" otherButtonTitles:nil]; [alert show]; [alert release]; } The MPMoviePlayerPlaybackDidFinishNotification is always fired but MPMoviePlayerContentPreloadDidFinishNotification is never fired. Any ideas ?

• iphone segmented control and uitableview

  - by Emma

  I have a UITableView with a segmented control at the top. When you tap on the different segments, I want the table to reload with a new different sized array. I have tried everything including [self.tableView reloadData]. When you click on a different tab now, it only changes the cells that are out of view and does not add any more. Any ideas??? Thanks.

• iphone how to remove modal uiviewcontroller from memory

  - by Scott Pendleton

  I have a root UIViewController which has a property called webView. WebView is a UIViewController with a XIB that contains a UIWebView. From my root view I modally (is there any other way?) load the webView ViewController and set its URL, always to the same page. I discovered that if, after loading the webView, I used its default Web page to navigate to another Web page, and then closed the webView and returned to the root controller -- AND THEN reopened the webView, that the webView was not showing the default page but rather the page I navigated to, which means the webView ViewController never got destroyed and removed from memory. This strikes me as very bad. So in the root ViewController, I added this code under viewWillAppear:animated -- if (self.webView != nil) { self.webView = nil) } Is that sufficient? Is there a better way?

• UIModalPresentationFormSheet and MPMoviePlayer on iPhone/iPad OS 3.2?

  - by user325699

  I have a UIModalPresentationFormSheet which has a movie player inside of it. When the user hits the button to play it in full screen, my UIModalPresentationFormSheet is still there ontop of the video while it's playing in full screen, behind the window and behind the shadow. What do I need to do to get rid of the dim so the video is playing in fullscreen with being able to select buttons and not having an annoying dim ontop of it?

• Fluid iPhone Animation ala Plants vs Zombies

  - by RyJ

  If you've played Plants vs Zombies, you've seen how fluid and remarkable the character animation is. Can anyone assume how they are doing this? They don't seem to simply be animating bitmaps; the animation is too crisp, even as characters rotate and scale. The artwork looks vector, but I can't imagine that everything is drawn out using Core Graphics. Any ideas?

• How to re codesign iPhone app binary ?

  - by CodeFlakes

  I'd like to send a binary to a client without the source code. How can here sign the app for distribution on it's own name without recompiling everything (since he does not have the source code) I'm not talking about adhoc distribution. I've tried to codesign -f with another distribution profile but itunes connect refuses it.

• iPhone SDK : UIImageView - Collapsing animation

  - by chris.o.

  Hi All, I'm trying to animating across the screen a horizontal bar with a color gradient. For simplicity, I chose to make a png of the fully extended bar, assign it to a UIImageView, and (attempt to) animate resizing of it using a UIView animation. The problem is that in the "closed" state of the Image, the portion of the image showing is not the part that I want. The image is arranged so that from L to R, a white to red color gradient occurs. The right side (about 20 pixels) is solid red and is the part I want to show when the bar is "collapsed". I'm trying to extend the image out by about 100 pixels to its full width. I referenced the "Buy Now" button example for my code as it seemed relevant" http://stackoverflow.com/questions/1669804/uibutton-appstore-buy-button-animation My code: [UIView beginAnimations:@"barAnimation" context:nil]; [UIView setAnimationDuration:0.6]; CGRect barFrame = bookBar.bounds; if (fExtendBar) { barFrame.origin.x -= 100; barFrame.size.width += 100; } else { barFrame.origin.x += 100; barFrame.size.width -= 100; } bookBar.frame = barFrame; [UIView commitAnimations]; I feel like this should be possible, maybe by setting an "offsetOfImage" to display in the UIImageView, but I can't seem to make it work. Also, I've noticed that the behavior is kind of consistent with what happens in Interface Builder when you resize an image. Then again, I would think there would be a way to override this behavior programmatically. Any suggestions (including other approaches) are welcome. Thanks, chris.o.

  I've been working on a project for a few weeks now and today is the last day before it goes to client (typical).

• Iphone NSXMLParser NSCFString memory leak

  - by atticusalien

  I am building an app that parses an rss feed. In the app there are two different types of feeds with different names for the elements in the feed, so I have created an NSXMLParser NSObject that takes the name of the elements of each feed before parsing. Here is my code: NewsFeedParser.h #import @interface NewsFeedParser : NSObject { NSInteger NewsSelectedCategory; NSXMLParser *NSXMLNewsParser; NSMutableArray *newsCategories; NSMutableDictionary *NewsItem; NSMutableString *NewsCurrentElement, *NewsCurrentElement1, *NewsCurrentElement2, *NewsCurrentElement3; NSString *NewsItemType, *NewsElement1, *NewsElement2, *NewsElement3; NSInteger NewsNumElements; } - (void) parseXMLFileAtURL:(NSString *)URL; @property(nonatomic, retain) NSString *NewsItemType; @property(nonatomic, retain) NSString *NewsElement1; @property(nonatomic, retain) NSString *NewsElement2; @property(nonatomic, retain) NSString *NewsElement3; @property(nonatomic, retain) NSMutableArray *newsCategories; @property(assign, nonatomic) NSInteger NewsNumElements; @end NewsFeedParser.m #import "NewsFeedParser.h" @implementation NewsFeedParser @synthesize NewsItemType; @synthesize NewsElement1; @synthesize NewsElement2; @synthesize NewsElement3; @synthesize newsCategories; @synthesize NewsNumElements; - (void)parserDidStartDocument:(NSXMLParser *)parser{ } - (void)parseXMLFileAtURL:(NSString *)URL { newsCategories = [[NSMutableArray alloc] init]; URL = [URL stringByReplacingOccurrencesOfString:@" " withString:@""]; URL = [URL stringByReplacingOccurrencesOfString:@"\n" withString:@""]; URL = [URL stringByReplacingOccurrencesOfString:@" " withString:@""]; //you must then convert the path to a proper NSURL or it won't work NSURL *xmlURL = [NSURL URLWithString:URL]; // here, for some reason you have to use NSClassFromString when trying to alloc NSXMLParser, otherwise you will get an object not found error // this may be necessary only for the toolchain [[NSURLCache sharedURLCache] setMemoryCapacity:0]; [[NSURLCache sharedURLCache] setDiskCapacity:0]; NSXMLNewsParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; // Set self as the delegate of the parser so that it will receive the parser delegate methods callbacks.

Here is a screen shot of the Leaks instrument with the NSCFStrings leaking: http://img139.imageshack.us/img139/3997/leaks.png For the life of me I can't figure out where these leaks are coming from. Any help would be greatly appreciated.

• iphone global variables accessed from different views

  - by Rob

  Okay, so ultimately I want a program where the user can input simple data such as their name, date of birth, address, etc. and then have that information stay through multiple views. I am having the user input their information as UITextFields but their are multiple views that they are using to input the data. Is there a way that when the user inputs data in a UITextField - then moves to another view - then returns to the original view - that the data will still be in that UITextField? I figure since there are placeholders that there must be a command to show previously written text in that field when the viewController is called. Also, for the life of me, I can't figure out how to keep these variables global. I have read in multiple areas that I should define them in the AppDelegate as a simple: NSString *userName; NSString *userDOB; But how do I assign the strings from the UITextFields in a different view to these variables and then re-assign them to the UITextFields when the user returns to the place where they originally input them? (I apologize if I am not explaining this coherently - I am a bit of a newb)

• nsthread in iphone xcode

  - by BibiBuBu

  Good Day! i want to use nsthreads in a project of xcode that will call a function which is for the network access and will check that if the network is there or not, so i need to have a thread which will execute after lets say 1 minutes to check the connectivity. and will continue run unless the app is closed. [NSThread detachNewThreadSelector:@selector(startTheBackgroundJob) toTarget:self withObject:nil]; startTheBackgroundJob NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // wait for 3 seconds before starting the thread, you don't have to do that. This is just an example how to stop the NSThread for some time [NSThread sleepForTimeInterval:5]; //[self performSelectorInBackground:@selector(checkNet) withObject:nil]; [self performSelectorOnMainThread:@selector(checkNet) withObject:nil waitUntilDone:YES]; [pool release]; it works only for the first time but not any other, i mean only 1 loop it makes can somebody help me in this regard.

• Navigation (controller) in Tabbar (c) in Navigation (c) (iphone)

  - by Jonathan

  I want to have a TabBar controller inside a navigation controller. So that when an item is selected on the first Navigation Controller it pushes the TabBar into view. Inside this tabbar on the first tab is another navigation controller. However I only want one navigation bar. I've come up with 2 ways but not sure which way is better (Ie more acceptable etc)? 1) The first navigation controller isn't actually a navigation controller but to the user it looks like one. So when a cell is selected on it's table view the first navC's view is removed from the superview and the TabBarC's view is added, animation would have to be done manually. 2)The first NavC is actually a NavC and when an item is selected and the TabBar is pushed on to the screen the first NavC's navigationbar is hidden so that the first tab's navigationBar is the only nav bar on screen.

• Question regarding the iPhone In App Purchase capabilities

  - by Wesley

  Hi everyone. I am working on releasing an app that will greatly benefit from using the in app purchase model. The app is a sort of book viewer, and the content I would like to make available for purchase will be more books in various languages. Each book is stored in sqlite format, in separate .db files. Now, the way that my developer has set it all up is that he added a line onto the bottom of the info.plist file called databases. Inside that database section, I can type in 'es' as the key, and for the value the name of the spanish database, and it populates in a uitableview in spanish, using NSLocale. So it is very easy to setup and implement different databases, which is great, but now I am confused about how I can implement my in app purchase model. Sorry about the long winded intro, here is my question: Is it possible to have an in app purchase add a line to my info.plist file? Or if not, is it possible to have the purchase reveal a new and updated plist file altogether that I would have already setup correctly? Any help here would be appreciated. Thanks
