  • How to call JSON asynchronous in xcode/ iphone develope

    - by Frames84
    I'm using the JSON framework hosting on Google. What and it's a news app that loads JSON feeds, when app goes off to load the feed I want to display the UIActivityIndicatorView but I've found my JSON Access code is not being called asynchronous which is locking the user interface. I have highlighted the function in the code and can't figuree out without breaking how to change the code. #import "JSON DataAccess Wrapper.h" #import "JSON.h" @implementation JSON_DataAccess_Wrapper @synthesize dataItemList; ////////////////////////////////////////////// /* START FEED CONNECTION/ HANDLE METHODS */ ////////////////////////////////////////////// - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [responseData setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [responseData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { //label.text = [NSString stringWithFormat:@"Connection failed: %@", [error description]]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } - (NSString *)stringWithUrl:(NSURL *)url { NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:30]; NSData *urlData; NSURLResponse *response = nil; NSError *error = nil; /* HOW TO MAKE THE CALL BELOW ASYNCHRONOUS */ urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error]; return [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding]; } -(id) objectWithUrl:(NSURL *)url { SBJSON *jsonParser = [SBJSON new]; NSString *jsonString = [self stringWithUrl:url]; return [jsonParser objectWithString:jsonString error:NULL]; } - (NSMutableArray *) downloadJSONFeed { id response = [self objectWithUrl:[NSURL URLWithString:@"http://www.mysite.co.uk/index2.php?option=JSON"]]; NSMutableArray *feed = (NSMutableArray *) response; return feed; }

  • Creating an MJPEG Viewer Iphone

    - by Tony
    Hey all, Im trying to make a MJPEG viewer in Objective C but I'm having a bunch of issues with it. First off, Im using AsyncSocket(http://code.google.com/p/cocoaasyncsocket/) which lets me connect to the host. Here's what I got so far NSLog(@"Ready"); asyncSocket = [[AsyncSocket alloc] initWithDelegate:self]; //http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi NSError *err = nil; if(![asyncSocket connectToHost:@"kamera5.vfp.slu.se" onPort:80 error:&err]) { NSLog(@"Error: %@", err); } then in the didConnectToHost method: - (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{ NSLog(@"Accepted client %@:%hu", host, port); NSString *urlString = [NSString stringWithFormat:@"http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi"]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"GET"]; //set headers NSString *_host = [NSString stringWithFormat:host]; [request addValue:_host forHTTPHeaderField: @"Host"]; NSString *KeepAlive = [NSString stringWithFormat:@"300"]; [request addValue:KeepAlive forHTTPHeaderField: @"Keep-Alive"]; NSString *connection = [NSString stringWithFormat:@"keep-alive"]; [request addValue:connection forHTTPHeaderField: @"Connection"]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"Response Code: %d", [urlResponse statusCode]); if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) { NSLog(@"Response: %@", result); //here you get the response } } This calls the MJPEG stream, but it doesn't call it to get more data. What I think its doing is just loading the first chunk of data, then disconnecting. Am I doing this totally wrong or is there light at the end of this tunnel? Thanks!

  • iPhone app running in Instruments fails with unrecognized selector

    - by Mark Smith
    I have an app that appears to run without problems in normal use. The Clang Static Analyzer reports no problems either. When I try to run it in Instruments, it fails with an unrecognized selector exception. The offending line is a simple property setter of the form: self.bar = baz; To figure out what's going on, I added an NSLog() call immediately above it: NSLog(@"class = %@ responds = %d", [self class], [self respondsToSelector:@selector(setBar:)]); self.bar = baz; On the emulator (without Instruments) and on a device, this shows exactly what I'd expect: class = Foo responds = 1 When running under Instruments, I get: class = Foo responds = 0 I'm stumped as to what could cause this. Perhaps a different memory location is getting tromped on when it's in the Instruments environment? Can anyone suggest how I might debug this?

  • Retain count problem iphone sdk

    - by neha
    Hi all, I'm facing a memory leak problem which is like this: I'm allocating an object of class A in class B. // RETAIN COUNT OF CLASS A OBJECT BECOMES 1 I'm placing the object in an nsmutablearray. // RETAIN COUNT OF CLASS A OBJECT BECOMES 2 In an another class C, I'm grabbing this nsmutablearray, fetching all the elements in that array in a local nsmutablearray, releasing this first array of class B. // RETAIN COUNT OF CLASS A OBJECTS IN LOCAL ARRAY BECOMES 1 Now in this class C, I'm creating an object of class A and fetching the elements in local nsmutable array. //RETAIN COUNT OF NEW CLASS A OBJECT IN LOCAL ARRAY BECOMES 2 [ALLOCATION + FETCHED OBJECT WITH RETAIN COUNT 1] My question is, I want to retain this array which I'm displaying in tableview, and want to release it after new elements are filled in the array. I'm doing this in class B. So before adding new elements, I'm removing all the elements and releasing this array in class B. And in class C I'm releasing object of class A in dealloc. But in Instruments-Leaks it's showing me leak for this class A object in class C. Can anybody please tell me wheather where I'm going wrong. Thanx in advance.

  • iphone initializing tab bar controller view programatically

    - by unsorted
    I want to initialize my tab bar controller programatically, but I just get a blank screen with the code I have. I tried to imitate TheElements sample app, and stuff seems comparable going line-by-line, but obviously something's wrong. Any suggestions? Thanks... In main.m: #import <UIKit/UIKit.h> int main(int argc, char *argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int retVal = UIApplicationMain(argc, argv, nil, @"DubbleWrapAppDelegate"); [pool release]; return retVal; } In DubbleWrapAppDelegate.h: @interface DubbleWrapAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; @end In DubbleWrapAppDelegate.m: @implementation DubbleWrapAppDelegate @synthesize window; @synthesize tabBarController; - init { if (self = [super init]){ // initialize to nil window = nil; tabBarController = nil; } return self; } - (void)applicationDidFinishLaunching:(UIApplication *)application { SafeTableViewController *vc1 = [[SafeTableViewController alloc] initWithStyle:UITableViewStylePlain]; [vc1 setSafeItems:[SafeItem knownSafeItems]]; // Set the list of known SafeItems: UINavigationController *nc1; nc1 = [[UINavigationController alloc] initWithRootViewController:vc1]; [vc1 release]; BoxXRayTableViewController *vc2 = [[BoxXRayTableViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *nc2; nc2 = [[UINavigationController alloc] initWithRootViewController:vc2]; [vc2 release]; AboutLibertyViewController *vc3 = [[AboutLibertyViewController alloc] init]; UINavigationController *nc3; nc3 = [[UINavigationController alloc] initWithRootViewController:vc3]; [vc3 release]; NSArray* controllers = [NSArray arrayWithObjects:nc1, nc2, nc3, nil]; tabBarController = [[UITabBarController alloc] init]; tabBarController.viewControllers = controllers; [controllers release]; // Add the tab bar controller's current view as a subview of the window window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; [window setBackgroundColor:[UIColor redColor]]; [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; [nc1 release]; [nc2 release]; [nc3 release]; } The plist is set so that there is no NIB file referenced.

  • NSNumberFormatter crashing iPhone SDK 4.0b2

    - by Ward
    Hey there, I've got an app that's been in the app store for a while and functions perfectly on OS 3.1 - 3.13. However, when tested on 4.0b2 I noticed that it crashes in the same place every time, but only on the device, never on the simulator. I'm using a 3GS to test. On loadView I initialize an NSNumberFormatter object which is declared and retained in the interface so I have access to it everywhere. In my method I call it several times to convert string values into nsnumbers to be stored in a mutable dictionary. Here's an example: [myDictionary setObject:[myStyleFormatter numberFromString:@"1"] forKey:@"hours"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"30"] forKey:@"minutes"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"10"] forKey:@"seconds"]; For some reason it crashes as soon as it tries to set hours. The error is "attempt to insert nil value (key: hours)" Have I been doing something wrong all along? Has the api changed for 4.0b2? Thanks, Howie

  • IPhone SDK Default NSUserDefaults...

    - by Harry
    I have set up the user defaults to record a integer for a UISlider, the problem is that, if the user has only just installed the app then the integer is zero or NULL. Is there a way to detect if it = NULL with a integer? heres my code i have so far: -(void)awakeFromNib { NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; senset = [prefs integerForKey:@"senset"]; senset = sensitivity.value; } - (IBAction) setSens { senset = sensitivity.value; } - (IBAction) goBackopt { { NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; [prefs setInteger:senset forKey:@"senset"]; [prefs synchronize]; } } senset is the integer. i have tried this code, and it sets it to 25 on the first time, but then if i try and overwrite it, it wont work and keeps setting it to 25. :( if ( [prefs integerForKey:@"senset"] == NULL ) { senset = 25; } Please help :P Harry

  • toggling proximity sensor on iPhone loses an event

    - by slugolicious
    I'm using setProximitySensingEnabled and implemented proximityStateChanged in my UIApplication subclass. It looks like if sensing is toggled, that the first "off" event is being lost. My UIApplication class is pretty basic... -(void)proximityStateChanged:(BOOL)state { NSLog(state ? @"ON" : @"OFF"); } In my application delegate, I have a UISwitch that enables/disables the proximity sensor. -(IBAction)toggleProxy:(id)sender { [UIApplication sharedApplication].proximitySensingEnabled = prox.on; } "prox" is my UISwitch. The test works fine when it first starts. I tap the switch to turn it on and then put my hand over the sensor for a second then move it away and get: 2009-03-11 12:43:00.465 Proximity[324:20b] ON 2009-03-11 12:43:02.514 Proximity[324:20b] OFF 2009-03-11 12:43:04.046 Proximity[324:20b] ON 2009-03-11 12:43:05.621 Proximity[324:20b] OFF I then tap the switch to turn it off then tap again to turn it on. Now I get: 2009-03-11 12:43:12.005 Proximity[324:20b] ON 2009-03-11 12:43:14.789 Proximity[324:20b] ON 2009-03-11 12:43:16.467 Proximity[324:20b] OFF 2009-03-11 12:43:17.516 Proximity[324:20b] ON 2009-03-11 12:43:19.077 Proximity[324:20b] OFF Notice I get two ON's before an OFF. The OFF is lost somewhere. I can't replicate this behavior using Google's mobile app so I'm wondering if they're resetting something in between proximity enabling. They don't have the proximity sensor on all the time because if you cover the sensor, the screen doesn't go blank. You have to tilt the phone up and angle it back (to simulate the position it would be in at your ear) and then covering the sensor works. Anyone else playing with the sensor? In my particular app, I'm recording a voice message and when you move the phone away from your ear, I want to pause the recording (when I get an OFF). The first time I move the phone away from my ear, the recording is not paused. However, if I put it to my ear and move it away again, it is paused.

  • Can NSDictionary be used with TableView on iPhone?

    - by bobo
    In a UITableViewController subclass, there are some methods that need to be implemented in order to load the data and handle the row selection event: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; //there is only one section needed for my table view } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [myList count]; //myList is a NSDictionary already populated in viewDidLoad method } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease ]; } // indexPath.row returns an integer index, // but myList uses keys that are not integer, // I don't know how I can retrieve the value and assign it to the cell.textLabel.text return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Handle row on select event, // but indexPath.row only returns the index, // not a key of the myList NSDictionary, // this prevents me from knowing which row is selected } How is NSDictionary supposed to work with TableView? What is the simplest way to get this done?

  • iPhone sdk Cocoa Touch - Pass touches down from parent UIView to child UIScrollview

    - by Joe
    I have a UIView inside my xib in IB and inside that is a UIScrollview that is a small 80x80 square and dynamically loaded with 8 or so 80 x 80 thumbnail images. The UIScrollview is not clipping the images so that they extend out either side so you can swipe left and right to scroll a chosen image into the the centre, paging is on so they snap ti each image. I have researched and found this is the best and possibly only way to do this. The UIScrollview sits in a 'container' UIView for one reason, it is there to receive the touches/swipes and pass them down to it's child the UIScrollview as otherwise all touches would have to start in the small 80x80 UIScrollview area and I wan them to be anywhere along the row of images. I have seen some sample code somewhere for doing this but just can not implement it. Treat me as a noob, starting from beginning to end, how should the UIView and UIScrollview be set up in IB to allow any touches to be passed, and what code should I put into where? The UIView is set up as scroll_container and the child UIScrollview is char_scroll At the moment I have got it all working except for the touches being passed from the parent to the child, and at the moment the touches have to always start inside the UIScrollview (tiny 80x80 box in centre) when I want to be able to swipe left or right in the long 480X80 horizontal parent UIView and have this still scroll the child UIScrollview. Hope you can help and understand what I mean!

  • Removing Shine/Gloss effect on the iPhone through UIPrerenderedIcon not working on device

    - by hbStarkMuffie
    Hello all, I have tried to use the UIPrerenderedIcon/"Icon already includes gloss and bevel" on the Info.plist of my app and it worked perfectly on the Simulator, but not on the real device (iPod touch 2g). I have even tried to uninstall the app from the device, clean all builds but I still got the shine/gloss, that's really ruining my icon... Any thoughts? Best Regards, Muffie

  • [SOLVED] 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. [NSXMLNewsParser setDelegate:self]; // Depending on the XML document you're parsing, you may want to enable these features of NSXMLParser. [NSXMLNewsParser setShouldProcessNamespaces:NO]; [NSXMLNewsParser setShouldReportNamespacePrefixes:NO]; [NSXMLNewsParser setShouldResolveExternalEntities:NO]; [NSXMLNewsParser parse]; [NSXMLNewsParser release]; } - (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError { NSString * errorString = [NSString stringWithFormat:@"Unable to download story feed from web site (Error code %i )", [parseError code]]; NSLog(@"error parsing XML: %@", errorString); UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:@"Error loading content" message:errorString delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [errorAlert show]; [errorAlert release]; [errorString release]; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ NewsCurrentElement = [elementName copy]; if ([elementName isEqualToString:NewsItemType]) { // clear out our story item caches...

[NewsItem setObject:NewsCurrentElement1 forKey:NewsElement1]; [NewsItem setObject:NewsCurrentElement2 forKey:NewsElement2]; if(NewsNumElements == 3) { [NewsItem setObject:NewsCurrentElement3 forKey:NewsElement3]; } [newsCategories addObject:[[NewsItem copy] autorelease]]; [NewsCurrentElement release]; [NewsCurrentElement1 release]; [NewsCurrentElement2 release]; if(NewsNumElements == 3) { [NewsCurrentElement3 release]; } [NewsItem release]; } } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { //NSLog(@"found characters: %@", string); // save the characters for the current item... if ([NewsCurrentElement isEqualToString:NewsElement1]) { [NewsCurrentElement1 appendString:string]; } else if ([NewsCurrentElement isEqualToString:NewsElement2]) { [NewsCurrentElement2 appendString:string]; } else if (NewsNumElements == 3 && [NewsCurrentElement isEqualToString:NewsElement3]) { [NewsCurrentElement3 appendString:string]; } } - (void)dealloc { [super dealloc]; [newsCategories release]; [NewsItemType release]; [NewsElement1 release]; [NewsElement2 release]; [NewsElement3 release]; } When I create an instance of the class I do like so: NewsFeedParser *categoriesParser = [[NewsFeedParser alloc] init]; if(newsCat == 0) { categoriesParser.NewsItemType = @"article"; categoriesParser.NewsElement1 = @"category"; categoriesParser.NewsElement2 = @"catid"; } else { categoriesParser.NewsItemType = @"article"; categoriesParser.NewsElement1 = @"category"; categoriesParser.NewsElement2 = @"feedUrl"; } [categoriesParser parseXMLFileAtURL:feedUrl]; newsCategories = [[NSMutableArray alloc] initWithArray:categoriesParser.newsCategories copyItems:YES]; [self.tableView reloadData]; [categoriesParser release]; If I run the app with the leaks instrument, the leaks point to the [NSXMLNewsParser parse] call in the NewsFeedParser.m. 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 app memory leak

    - by Marian Busoi
    Any idea why this code gives me a memory leak? As you can see, I'm running out of ideas as to what I can do to stop it. (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; NSArray *allSketches = [project.sketches allObjects]; NSMutableArray *temp = [[NSMutableArray alloc] initWithArray:allSketches]; if(sketchesArray != nil) [sketchesArray release]; [self setSketchesArray:temp]; [allSketches release]; allSketches = nil; [temp release]; temp = nil; } I also release sketchesArray inside viewDidDissapear. I'm not using viewDidLoad and dealloc to init/release these objects as what I am doing requires me to use viewWillAppear and viewDidDissapear. Thanks

  • Difficulties signing in to Twitter from iPhone

    - by Tristan
    Hi there, I'm using MGTwitterEngine to add Twitter functionality to my app. It's very easy to simply prompt the user for a username and password and then start posting. Strangely, however, I've noticed other apps (eg Foursquare and Brightkite) require you to visit their website to associate your Twitter account with your foursquare/brightkite/whatever account. Why do they do it this way? Is there a reason why my app shouldn't prompt the user for a Twitter username and password, even though it would be so easy? Thanks a bunch! Tristan

  • iphone cannot rotate views in TabBar controller

    - by Luc
    Hello, I am working on an application that consists of a TabBar controller. Within on of its tab, I have a subclass of UITableViewController, within this list I have a Core-plot graph in the first cell and some other data in the 4 following cells. When I return YES in the shouldAutorotateToInterfaceOrientation method, I would expect the autoresizing of the list view to happen, but... nothing. When I add some log in the willRotateToInterfaceOrientation method, they are not displayed. Is there something I missed ? Thanks a lot, Luc // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations //return (interfaceOrientation == UIInterfaceOrientationPortrait); NSLog(@"Orientation"); return YES; } - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration]; NSLog(@"Rotating"); if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) { NSLog(@"view land:%@", self.view); } if (toInterfaceOrientation == UIInterfaceOrientationPortrait) { NSLog(@"view portrait:%@", self.view); } }

  • Locate RFID tag using iPhone

    Hi all, I am looking into building an app (on my laptop to start) that would be able to locate the signal emitted by an RFID tag (non passive). Say I attach this to my key ring, what would be required of the application to triangulate the location of the RFID tag in a 10m range. Would this even be possible using this technology? I see some older posts here so wondering if there have been any tech breakthroughs in this area since then? Dan

  • Webservices on iPhone - wsdl2objc - Sample Code?

    - by markmcgookin
    I have recently downloaded the most recent build of this awesome tool WSDL2OBJC from google code here: http://code.google.com/p/wsdl2objc/ After a bit of tweaking and downloading the latest version of the trunk from the svn repo I got a version that created the code for a WSDL I am using and compiles great and actually installs on my phone! However, I'm not doing anything with it yet, because I am not really sure how to. There is very little in the way of sample code on the site, and there is a sample file in the project if you download it, but again it is very complicated and there are no real bits of documentation. Has anyone managed to successfully use this stuff? It seems SOOO powerful and useful but from a look around the Internet, no one knows how to use it. We (all) would love someone who has figured it out to post a simple project or detailed walk-through of implementing this so we can put the code that lots of people have worked hard on to good use. If anyone has found a blog entry or has this information it would be great to see! I am totally stuck... with no errors. I would love to know how to use this now that it's all compiled successfully!

  • iPhone - Setting background on UITableView

    Is there any way to set a background view on a UITableViewController? I try with the code I am using on a UIViewController, but the view comes over all the contents of the table view, and if I add the background view in the cellForRowAtIndexPath-method, it is not showing at all. Anyone done this before or have an idea on how it can be done? Here is the code I am using: UIImage *image = [UIImage imageNamed: @"background.jpg"]; UIImageView *backImage = [[UIImageView alloc] initWithImage: image]; [self.view addSubview: backImage]; [self.view sendSubviewToBack: backImage]; Thanks
