  • GKTank example is not working.

    - by david
    Hello, I'm trying to get the GKTank example working with 2 iPhones. Both have bluetooth enabled. I start the app on both devices and tap the screen. The Peer Picker comes up and the devices find each other. If I select one device in the list it says "Waiting for {other iPhone}..." forever. On the {other iPhone} the waiting phone gets grayed out. If I select the device to connect to from both devices at the same time both go into waiting state forever... The debug log says this if I select the other iPhone on the debugged device: 2010-05-30 23:20:24.331 GKTank[2433:4e03] handleEvents started (2) 2010-05-30 23:20:25.269 GKTank[2433:4e03] ~ DNSServiceRegister callback: Ref=135f70, Flags=2, ErrorType=0 name=00oRWv-0A..David’s iPhone regtype=_gktank._udp. domain=local. 2010-05-30 23:20:25.375 GKTank[2433:4e03] ~ DNSServiceBrowse callback: Ref=134f30, Flags=2, IFIndex=8 (name=[en2]), ErrorType=0 name=00oRWv-0A..David’s iPhone regtype=_gktank._udp. domain=local. 2010-05-30 23:20:30.691 GKTank[2433:4e03] ~ DNSServiceBrowse callback: Ref=134f30, Flags=2, IFIndex=-3 (name=[]), ErrorType=0 name=00K83eS0A..iPhone von Tamara regtype=_gktank._udp. domain=local. 2010-05-30 23:20:30.855 GKTank[2433:4e03] ~ DNSServiceQueryRecord callback: Ref=13a320, Flags=2, IFIndex=-3 (name=[]), ErrorType=0 fullname=00k83es0a..iphone\032von\032tamara._gktank._udp.local. rrtype=16 rrclass=1 rdlen=18 ttl=7200 2010-05-30 23:20:30.872 GKTank[2433:4e03] ** peer 480260628: oldbusy=0, newbusy=0 2010-05-30 23:20:35.215 GKTank[2433:207] ** Stop resolving? potentially previous resolves 2010-05-30 23:20:35.226 GKTank[2433:207] **** BEGIN RESOLVE: 480260628 and it stays that way.

  • NSCollectionView draws nothing

    - by PCWiz
    I'm trying to set up an NSCollectionView (I have done this successfully in the past, but for some reason it fails this time). I have a model class called "TestModel", and it has an NSString property that just returns a string (just for testing purposes right now). I then have an NSMutableArray property declaration in my main app delegate class, and to this array I add instances of the TestModel object. I then have an Array Controller that has its Content Array bound the app delegate's NSMutableArray. I can confirm that everything up to here is working fine; NSLogging: [[[arrayController arrangedObjects] objectAtIndex:0] teststring] worked fine. I then have all the appropriate bindings for the collection view set up, (itemPrototype and content), and for the Collection View Item (view). I then have a text field in the collection item view that is bound to Collection View Item.representedObject.teststring. However NOTHING displays in the collection view when I start the app, just a blank white screen. What am I missing? UPDATE: Here is the code I use (requested by wil shipley): // App delegate class @interface AppController : NSObject { NSMutableArray *objectArray; } @property (readwrite, retain) NSMutableArray *objectArray; @end @implementation AppController @synthesize objectArray; - (id)init { if (self = [super init]) { objectArray = [[NSMutableArray alloc] init]; } return self; } - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { TestModel *test = [[[TestModel alloc] initWithString:@"somerandomstring"] autorelease]; if (test) [objectArray addObject:test]; } @end // The model class (TestModel) @interface TestModel : NSObject { NSString *teststring; } @property (readwrite, retain) NSString *teststring; - (id)initWithString:(NSString*)customString; @end @implementation TestModel @synthesize teststring; - (id)initWithString:(NSString*)customString { [self setTeststring:customString]; } - (void)dealloc { [teststring release]; } @end And then like I said the content array of the Array Controller is bound to this "objectArray", and the Content of the NSCollectionView is bound to Array Controller.arrangedObjects. I can verify that the Array Controller has the objects in it by NSLogging [arrayController arrangedObjects], and it returns the correct object. Its just that nothing displays in the NSCollectionView. UPDATE 2: If I log [collectionView content] I get nothing: 2009-10-21 08:02:42.385 CollViewTest[743:a0f] ( ) The problem is probably there. UPDATE 3: As requested here is the Xcode project: http://www.mediafire.com/?mjgdzgjjfzw Its a menubar app, so it has no window. When you build and run the app you'll see a menubar item that says "test", this opens the view that contains the NSCollectionView. Thanks

  • NSURLConnection not "firing" until UITableView scrolls..

    - by Simon
    Hi, I've got a UITableView that loads an image asynchronously and places it in the UITableViewCell once it's loaded (I'm using almost the exact same code as in the "LazyTableImages" tutorial). This works fine for all images when I scroll the table, but it's not loading the images that are first in the view. The code is definitely working fine as the class that actually sends the NSURLConnection request is being called correctly (I added an NSLog and it reached the console). The NSURLConnection is just not calling the delegate methods (didReceiveData, connectionDidFinishLoading, etc). Here's my code: HomeController.m - (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]; NSArray *feed = [feeds objectAtIndex: indexPath.row]; /** * Name of person */ [...] /** * Feed entry */ [...] /** * Misc work */ [...] } FeedRecord *feedRecord = [self.entries objectAtIndex:indexPath.row]; if( !feedRecord.image ) { if (self.table.dragging == NO && self.table.decelerating == NO) { [self startIconDownload:feedRecord forIndexPath:indexPath]; } cell.imageView.image = [UIImage imageNamed:@"Placeholder.png"]; } return cell; } - (void)startIconDownload:(FeedRecord *)feedRecord forIndexPath:(NSIndexPath *)indexPath { IconDownloader *iconDownloader = [imageDownloadsInProgress objectForKey:indexPath]; if (iconDownloader == nil) { iconDownloader = [[IconDownloader alloc] init]; iconDownloader.feedRecord = feedRecord; iconDownloader.indexPathInTableView = indexPath; iconDownloader.delegate = self; [imageDownloadsInProgress setObject:iconDownloader forKey:indexPath]; [iconDownloader startDownload]; [iconDownloader release]; } } IconDownload.m #import "IconDownloader.h" #import "FeedRecord.h" #define kAppIconHeight 48 @implementation IconDownloader @synthesize feedRecord; @synthesize indexPathInTableView; @synthesize delegate; @synthesize activeDownload; @synthesize imageConnection; #pragma mark - (void)dealloc { [feedRecord release]; [indexPathInTableView release]; [activeDownload release]; [imageConnection cancel]; [imageConnection release]; [super dealloc]; } - (void)startDownload { NSLog(@"%@ %@",@"Started downloading", feedRecord.profilePicture); // this shows in log self.activeDownload = [NSMutableData data]; // alloc+init and start an NSURLConnection; release on completion/failure NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest: [NSURLRequest requestWithURL: [NSURL URLWithString:feedRecord.profilePicture]] delegate:self]; self.imageConnection = conn; NSLog(@"%@",conn); // this shows in log [conn release]; } - (void)cancelDownload { [self.imageConnection cancel]; self.imageConnection = nil; self.activeDownload = nil; } #pragma mark - #pragma mark Download support (NSURLConnectionDelegate) - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@ %@",@"Got data for", feedRecord.profilePicture); [self.activeDownload appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"Fail!"); // Clear the activeDownload property to allow later attempts self.activeDownload = nil; // Release the connection now that it's finished self.imageConnection = nil; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"%@ %@",@"Done", feedRecord.profilePicture); // Set appIcon and clear temporary data/image UIImage *image = [[UIImage alloc] initWithData:self.activeDownload]; self.feedRecord.image = image; self.activeDownload = nil; [image release]; // Release the connection now that it's finished self.imageConnection = nil; NSLog(@"%@ %@",@"Our delegate is",delegate); // call our delegate and tell it that our icon is ready for display [delegate feedImageDidLoad:self.indexPathInTableView]; } @end Has anyone else experienced anything like this or can identify an issue with my code? Thanks!

  • Xcode is not building the Binary

    - by Stephen Furlani
    Hello, Xcode is doing something bizzare which I at one point in time fixed but now for the life of me I can't figure out what's wrong. Xcode is building my project fine - no errors on a clean-all build. All my product names and info.plists agree, all the settings appear to be correct. I've only got the one build configuration (I always delete all of them except when I got to actually release something - waay to many invisible problems with these things). Except that it is not generating binaries for my code. Eh wot? I have recently checked the code out on a new computer, and I checked all the paths and everything exists where it should. any help is appreciated. It is not throwing any errors and neither the binary for the .app nor the .plugin (project.app/Contents/MacOS/THERE IS NOTHING HERE). Thanks!!! -Stephen

  • iPhone Twitter Get UserId

    - by Mick Walker
    Hi, I am looking for a way to get a twitter users userid via their username. For example take http://twitter.com/AlySSa_miLAno (yes I know her twitter page off by heart lol) on the right hand side of the page is a link to her RSS feed: feed://twitter.com/statuses/user_timeline/26642006.rss In this context Alyssa's userid would be 26642006. Ideally I would like to avoid reading the full content of the page, as this could be quite expensive on a mobile device, so if anyone knows how to accomplish this using any Twitter/3rd party webservices that would be great.

  • Implementing A Static NSOutlineView

    - by spamguy
    I'm having a hard time scraping together enough snippets of knowledge to implement an NSOutlineView with a static, never-changing structure defined in an NSArray. This link has been great, but it's not helping me grasp submenus. I'm thinking they're just nested NSArrays, but I have no clear idea. Let's say we have an NSArray inside an NSArray, defined as NSArray *subarray = [[NSArray alloc] initWithObjects:@"2.1", @"2.2", @"2.3", @"2.4", @"2.5", nil]; NSArray *ovStructure = [[NSArray alloc] initWithObjects:@"1", subarray, @"3", nil]; The text is defined in outlineView:objectValueForTableColumn:byItem:. - (id)outlineView:(NSOutlineView *)ov objectValueForTableColumn:(NSTableColumn *)tableColumn byItem:(id)ovItem { if ([[[tableColumn headerCell] stringValue] compare:@"Key"] == NSOrderedSame) { // Return the key for this item. First, get the parent array or dictionary. // If the parent is nil, then that must be root, so we'll get the root // dictionary. id parentObject = [ov parentForItem:ovItem] ? [ov parentForItem:ovItem] : ovStructure; if ([parentObject isKindOfClass:[NSArray class]]) { // Arrays don't have keys (usually), so we have to use a name // based on the index of the object. NSLog([NSString stringWithFormat:@"%@", ovItem]); //return [NSString stringWithFormat:@"Item %d", [parentObject indexOfObject:ovItem]]; return (NSString *) [ovStructure objectAtIndex:[ovStructure indexOfObject:ovItem]]; } } else { // Return the value for the key. If this is a string, just return that. if ([ovItem isKindOfClass:[NSString class]]) { return ovItem; } else if ([ovItem isKindOfClass:[NSDictionary class]]) { return [NSString stringWithFormat:@"%d items", [ovItem count]]; } else if ([ovItem isKindOfClass:[NSArray class]]) { return [NSString stringWithFormat:@"%d items", [ovItem count]]; } } return nil; } The result is '1', '(' (expandable), and '3'. NSLog shows the array starting with '(', hence the second item. Expanding it causes a crash due to going 'beyond bounds.' I tried using parentForItem: but couldn't figure out what to compare the result to. What am I missing?

  • drawRect context Error

    - by user361228
    Hi, I heard that a lot of people get a context error by not using drawRect Now I have this: - (void)drawRect:(CGRect)rect { NSLog(@"drawRect: Starts"); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetRGBStrokeColor(context, 1.0, 1.0, 1.0, 1.0); CGContextSetLineWidth(context, 3.0); CGContextMoveToPoint(context, lineStart.x, lineStart.y); CGContextAddLineToPoint(context, lineEnd.x, lineEnd.y); CGContextStrokePath(context); } Error: <Error>: CGContextSetRGBStrokeColor: invalid context Which had work on previous programs, but not on this one. Whats different: I have a view controller, which calls this UIView: -(void)createLine:(CGPoint)start:(CGPoint)end { NSLog(@"createLine: Starts"); lineEnd = start; lineStart = end; self = [super initWithFrame:drawRect:CGRectMake(fmin(lineStart.x, lineEnd.x), fmin(lineStart.y, lineEnd.y), fabs(lineStart.x - lineEnd.x), fabs(lineStart.y - lineEnd.y))]; } This is my first question, and I am not sure how much info code I should be putting here so be easy on me :D Thanks

  • invalid context 0x0 under iOS 7.0 and system degradation

    - by Alex
    I've read as many search results I could find on this dreaded problem, unfortunatelly, each one seems to focus on a specific function call. My problem is that I get the same error from multiple functions, which I am guessing are being called back from functions that I use. To make matters worse, the actual code is within a custom private framework which is being imported in another project, and as such, debugging isn't as simple? Can anyone point me to the right direction? I have a feeling I'm calling certain methods wrongly or with bad context, but the output from xcode is not very helpful at this point. : CGContextSetFillColorWithColor: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability.

At which point they spawn multiple times, until the keyboard won't provide any input. Touch events are still registered, but system slows down, and eventually may lead to unallocated object errors.

  • SQLite - a smart way to remove and add new objects

    - by Ilya
    Hi, I have a table in my database and I want for each row in my table to have an unique id and to have the rows named sequently. For example: I have 10 rows, each has an id - starting from 0, ending at 9. When I remove a row from a table, lets say - row number 5, there occurs a "hole". And afterwards I add more data, but the "hole" is still there. It is important for me to know exact number of rows and to have at every row data in order to access my table arbitrarily. There is a way in sqlite to do it? Or do I have to manually manage removing and adding of data? Thank you in advance, Ilya.

  • URLCache - iPhone SDK

    Hello everyone.. I need some help in using the NSURLCache to download a simple file. It would need to be saved in the Documents folder of the app. I have seen the URLCache example that apple presented, but I didn't find it useful since it was an image that was being shown. In addition there was some complex code on the modification date. I actually need something when the application opens it will begin the download process. Can someone guide me through just the download process of any file? Thanks Kevin

  • iPhone metering problems

    - by Eric Christensen
    When I'm recording an AVAudioRecorder object, I repeat a chunk of code via an NSTimer that includes: [soundrecording updateMeters]; NSLog(@"channel 0 average:%f, peak:%f",[soundrecording averagePowerForChannel:0],[soundrecording peakPowerForChannel:0]); NSLog(@"channel 1 average:%f, peak:%f",[soundrecording averagePowerForChannel:1],[soundrecording peakPowerForChannel:1]); When I'm recording a mono file, the peak power for channel 0 is just what you'd expect, a float from -160 to 0. But average power for channel 0 is always zero. (And, of course, the values for channel 1 are both zero.) When I'm recording a stereo file, both the average and peak values for both channels are as expected. Any thoughts on why, when recording a mono file, the average value for channel 0 isn't returning correctly, even though the peak is? Thanks!

  • Help with iphone button pressed

    - by StealthRT
    I am trying to see which button was clicked on so I can preform the correct logic. This is the code for the buttons: UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(270, 423, 60, 60)]; [button addTarget:self action:@selector(buttonPressedAction:) forControlEvents:UIControlEventTouchUpInside]; [button setBackgroundImage:[[UIImage imageNamed:@"refreshicon.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; UIButton *button2 = [[UIButton alloc] initWithFrame:CGRectMake(0, 423, 60, 60)]; [button2 addTarget:self action:@selector(buttonPressedAction:) forControlEvents:UIControlEventTouchUpInside]; [button2 setBackgroundImage:[[UIImage imageNamed:@"login.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; [self.navigationController.view addSubview:button]; [self.navigationController.view addSubview:button2]; And this is how I call the buttonPressedAction: - (void)buttonPressedAction:(id)sender { NSLog(@"%@", [sender value]); isRefreshing = TRUE; [self loadTheXML]; [self.tableView reloadData]; } But when I use NSLog to see what the sender value is, it crashes. Any advice for what's happening and how to correct it?
