• iPhone Debugger Message -- Weird

  - by Bill Shiff

  Hello, I have an iPhone app that I've been working on and have recently upgraded my version of XCode. Since the upgrade, I can build and debug in the iPhone Simulator just fine, but when I try to debug on an attached device I get the following messages: From Xcode4: GNU gdb 6.3.50-20050815 (Apple version gdb-1510) (Fri Oct 22 04:12:10 UTC 2010) Copyright 2004 Free Software Foundation, Inc.

• Filter entire NSDictionaries out of NSArray based on multiple keys

  - by user270475

  Hi, I have an NSArray of NSDictionary objects which I would like to be able to return a new array of NSDictionaries from, where every NSDictionary has "Area == North" (for example). The closest example I have found so far is http://stackoverflow.com/questions/958622/using-nspredicate-to-filter-an-nsarray-based-on-nsdictionary-keys but this just returns the unique values for a given key, not the dictionary that has that key. Is there any way to perform a similar operation, and to return the entire dictionary?

• CoreData NSFetchedResultsController Empty Section Display

  - by user280390

  Hello I would like to show a fixed number of sections in a table view with a Fetched Results Controller as the data source. If you image the contacts app where sections organised by the alphabet, it will not have a header for B if there are no contacts in that section, so the section headers you see are A then C. I would like to display a section header in my table (for B), but without any rows. an empty section in effect. Can NSFetchedResultsController do this for me?

  - by srikanth rongali

  Hi, I am doing my program in cocos2d. I am using NSDate to get the current time of the start of animation. And I know my animation takes 3 seconds. So I can get the time at completion of animation by using NSInterval and using the previous time and animation time. But, if If the animation time interval is not fixed how can I calculate the time interval of the animation and time at the completion of the animation ? I am animating a sprite. Please help how can I make it. Thank You.

• Checking if an object has been released before sending a message to it

  - by Tom Irving

  I've only recently noticed a crash in one of my apps when an object tried to message its delegate and the delegate had already been released. At the moment, just before calling any delegate methods, I run this check: if (delegate && [delegate respondsToSelector:...]){ [delegate ...]; } But obviously this doesn't account for if the delegate isn't nil, but has been deallocated. Besides setting the object's delegate to nil in the delegate's dealloc method, is there a way to check if the delegate has already been released just incase I no longer have a reference to the object.

• how to customize NSTokenField like in "To/ CC" fields in mac mail?

  - by Miraaj

  Hi all, I am able to work with NSTokenField, it is easy to use.. but I want your suggestions on how can I customize it just like it is in "To/ CC" fields in mac mail ie. when no. of tokens in a token field increases height of "To" field gets increased to a certain limit then a vertical scroller starts appearing! By default when we use a token field neither its height gets increased nor a vertical scroller appears! I tried different combinations in IB but I could not obtain mac mail like functionality. Can anyone suggest me some solution for it?? Thanks, Miraaj

• zooming from a particular point

  - by Chandan Shetty SP

  I am using this code to zoom from a particular point CGPoint getCenterPointForRect(CGRect inRect) { CGRect screenRect = [[UIScreen mainScreen] bounds]; return CGPointMake((screenRect.size.height-inRect.origin.x)/2,(screenRect.size.width-inRect.origin.y)/2); } -(void) startAnimation { CGPoint centerPoint = getCenterPointForRect(self.view.frame); self.view.transform = CGAffineTransformMakeTranslation(centerPoint.x, centerPoint.y); self.view.transform = CGAffineTransformScale( self.view.transform , 0.001, 0.001); [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:kTransitionDuration]; self.view.transform = CGAffineTransformIdentity; [UIView commitAnimations]; } Its not working. What is the correct way to do zooming from a particular point.

• How can I call different sprites images and properties of it from a file ?

  - by srikanth rongali

  My small game consists of a player and 10 targets. I have an excel sheet of information of target. It includes the target speed, target accuracy, target probability of hitting of the player. These factors change from target1 to target10. Each time target should appear on screen starting from target1 to target10. How can I call them in such a way?

• Data sources and NSTableView

  - by lampShade

  I know that table sources need a data source to hold the data that the tableview will display. Lets' say that I'm going to make my AppController be the data source of my tableview and that I make the connection in interface builder. My question is since my actual data is going to be stored in an array,let's call it myArray, when I set the data source in code should I do this [tableView setDataSource:myArray]; or this [tableView setDataSource:self]; I'm confused about this. setting the data source with the keyword "self" would set it to the AppController if I'm not mistaken.

• problem with NSInputStream on real iPhone

  - by ThamThang

  Hi guys, I have a problem with NSInputStream. Here is my code: case NSStreamEventHasBytesAvailable: printf("BYTE AVAILABLE\n"); int len = 0; NSMutableData *data = [[NSMutableData alloc] init]; uint8_t buffer[32768]; if(stream == iStream) { printf("Receiving...\n"); len = [iStream read:buffer maxLength:32768]; [data appendBytes:buffer length:len]; } [iStream close]; I try to read small data and it works perfectly on simulator and real iPhone. If I try to read large data (more than 4kB or maybe 5kB), the real iPhone just can read 2736 bytes and stop. Why is it? Help me plz! Merci d'avance!

• How to call a method of a specific class from another class (created in this specific class) ?

  - by choise

  I created a TTModelViewController. in the createModel Method i created a TTURLRequestModel. after Loading content in the TTURLRequestModel i want to call a method in my TTModelViewController. TTModelViewController - (void) createModel { requestModel = [[singlePostModel alloc] initWithId:@"54"]; } - (void)didLoadModel:(BOOL)firstTime { NSLog(@"loaded"); } TTURLRequestModel (singlePostModel) - (void)requestDidFinishLoad:(TTURLRequest*)request { //doing something [super requestDidFinishLoad:request]; } first i thought "didLoadModel" gets called after requestDidFinishLoad was called, but its before. So, how can i call a method in my TTModelViewController after request is finished loading? is there a method that already does that and i only have to overwrite this? or something else? thanks // if knowbody knows how to do this with three20, anybody can tell me how to do this in general?

• iPhone TableView Data Into 2 Sections

  - by MrPink

  Hello, I am trying to get a tableview to split data i have in an array into sections... I'm pretty new to this but below is my code snippet - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if(section == 0) { contentArray = [[NSArray arrayWithObjects:@"Send SMS", @"Reports", nil] retain]; } if(section == 1) { contentArray = [[NSArray arrayWithObjects:@"Accounts", nil] retain]; } return [contentArray count]; } I have split the data successfully into the 2 sections but when populating the rows It just repeats the first content array in both sections. Can any one help... Thanks

• Do autoreleased objects always survive a whole method?

  - by Jan Hendrix

  Hi, If I'm correct then the releasing of the pool of autoreleased objects has something to do with the run loop.. I barely have an idea of what that 'run loop' is but my question is, is it possible that the object gets released before the end of the method is reached?

• How to detect a gamepad button press on OSX 10.5 and higher?

  - by Steph Thirion

  How do I detect a button press on a USB gamepad on OSX 10.5 and higher? I can't wrap my head around the ridiculously complex HID Manager (even though apparently it was simplified with 10.5), and the code samples at Apple have thousands of lines of code that would take days to understand and isolate what I need, so I'd appreciate if someone posts a simple, and fully coded solution for this isolated problem. EDIT: so far all answers are links to source code or semi obscure libraries for all kinds of HID devices, which will require more research time than what I'd like to invest on this. I am starting a bounty to get an actual snippet of code that solves this simple problem (using an external library or not). EDIT POS BOUNTY: thanks to all for you help; but unfortunately the answer that has been automatically selected by the system is not working for me, can't figure out why; and the author has not yet replied to my comments. Any insight would be appreciated, but until a fix is found, anyone looking for resources on this topic should take this answer with a pinch of salt.

• OOP App Architecture: Which layer does a lazy loader sit in?

  - by JW

  I am planning the implemention an Inheritance Mapper pattern for an application component http://martinfowler.com/eaaCatalog/inheritanceMappers.html One feature it needs to have is for a domain object to reference a large list of aggreageted items (10,000 other domain objects) So I need some kind of lazy loading collection to be passed out of the aggregate root domain object to other domain objects. To keep my (php) model scripts organised i am storing them in two folders: MyComponent\ controllers\ models\ domain\ <- domain objects, DDD repository, DDD factory daccess\ <- PoEAA data mappers, SQL queries etc views\ But now I am racking my brains wondering where my lazy loading collection sits. Any suggestions / justifications for putting it in one place over another another?

• How to remove an observer for NSNotification in a UIView?

  - by sudo rm -rf

  Hello! I've added an observer in a custom UIView I've created under initWithFrame:. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateZipFromLocation:) name:@"zipFoundFromLocation" object:nil]; The problem is, this view is a subview. When the view is loaded again, it calls the initWithFrame message again, thus adding two observers and so on. How can I remove the observer when the view is going to disappear? Since it is a UIView, it says that viewWillDisappear:(BOOL)animated is not a valid method. Any ideas?

• What would cause objectForKey: to return null with a valid string in place?

  - by theMikeSwan

  I am having an issue with NSDictionary returning null for an NSString even though the string in in the dictionary. Here is the code: - (void)sourceDidChange:(NSNotification *)aNote { NSDictionary *aDict = [aNote userInfo]; DLog(@"%@", aDict); NSString *newSourceString = [aDict objectForKey:@"newSource"]; DLog(@"%@", newSourceString); newSourceString = [newSourceString stringByReplacingOccurrencesOfString:@" " withString:@""]; DLog(@"%@", newSourceString); NSString *inspectorString = [newSourceString stringByAppendingString:@"InspectorController"]; DLog(@"%@", inspectorString); newSourceString = [newSourceString stringByAppendingString:@"ViewController"]; DLog(@"%@", newSourceString); } And I get the following log statements: 2010-04-17 23:50:13.913 CoreDataUISandbox[13417:a0f] -[RightViewController sourceDidChange:] newSource = "Second View"; 2010-04-17 23:50:13.914 CoreDataUISandbox[13417:a0f] -[RightViewController sourceDidChange:] (null) 2010-04-17 23:50:13.916 CoreDataUISandbox[13417:a0f] -[RightViewController sourceDidChange:] (null) 2010-04-17 23:50:13.917 CoreDataUISandbox[13417:a0f] -[RightViewController sourceDidChange:] (null) 2010-04-17 23:50:13.917 CoreDataUISandbox[13417:a0f] -[RightViewController sourceDidChange:] (null) As you can see the string is in the dictionary under the key newSource, yet when I call objectForKey: I get null. I have even tried the fallback option of cleaning the project. Has anyone ever run into this, or have I just forgotten something really basic?

• Problem while looping on a NSDictionary

  - by Tom

  Hi! The end of my loop causes a EXC_BAD_ACCESS. Here's my dictionary (AppDelegate.data): 1 = ( 3, "Test 1", False, "" ); 2 = ( 4, "Test 2", False, "" ); And here is my loop: for (id theKey in AppDelegate.data) { if (theKey = nil) { NSLog(@"HOLY COW"); } else { NSLog(@"Key: %@ ?", theKey); } } It never says holy cow, and it says the right key but at the end it crashes... Do you have any idea why? It should only loop on 1 and two and then exit the loop... I know that there's always a "nil" object at the end that's why I did a condition with it but it doesn't look like it works at all.. Thanks!

• audio power on AudioQueue

  - by Tomoyuki

  Hi everyone. I'm now creating an Application using speech recognition.To check the Audio Power coming in through the microphone, I wrote a method as follows. -(void)checkPower(AudioqueRef)queue{ UInt32 expectedSize= sizeof(AudioQueueLevelMeterState); AudioQueueGetProperty(queue, kAudioQueueProperty_CurrentLevelMeter, audioLevels, expectedSize); NSLog(@"average:%f peak:%f",audioLevels.mAveragePower,audioLevels.mPeakPower); } I found that sometimes mAveragePower was larger than mPeakPower, and when mAveragePower was 1.0, in other words, averagePower is regarded as max, mPeakPower was lower than 1.0. I think that generally this result is inpossible. please Let me know if you have any information about sound power on CoreAudio. thanks.
