• apt-get update mdadm scary warnings

  Just ran an apt-get update on one of my dedicated servers to be left with a relatively scary warning: Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-2.6.26-2-686-bigmem W: mdadm: the array /dev/md/1 with UUID c622dd79:496607cf:c230666b:5103eba0 W: mdadm: is currently active, but it is not listed in mdadm.conf. if W: mdadm: it is needed for boot, then YOUR SYSTEM IS NOW UNBOOTABLE!

• adding UIImageView to UIScrollView throws exception cocoa touch for iPad

  - by Brodie4598

  I am a noob at OBJ-C :) I am trying to add a UIImageView to a UIScrollView to display a large image in my iPad app. I have followed the tutorial here exactly: http://howtomakeiphoneapps.com/2009/12/how-to-use-uiscrollview-in-your-iphone-app/ The only difference is that in my App the View is in a seperate tab and I am using a different image. here is my code: - (void)viewDidLoad { [super viewDidLoad]; UIImageView *tempImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Cheyenne81"]]; self.imageView = tempImageView; [tempImageView release]; scrollView.contentSize = CGSizeMake(imageView.frame.size.width, imageView.frame.size.height); scrollView.maximumZoomScale = 4.0; scrollView.minimumZoomScale = 0.75; scrollView.clipsToBounds = YES; scrollView.delegate = self; [scrollView addSubview:imageView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{ return imageView; } and: @interface UseScrollViewViewController : UIViewController<UIScrollViewDelegate>{ IBOutlet UIScrollView *scrollView; UIImageView *imageView; } @property (nonatomic, retain) UIScrollView *scrollView; @property (nonatomic, retain) UIImageView *imageView; @end I then create a UIScrollView in Interface Builder and link it to the scrollView outlet. Thats when I get the problem. When I run the program it crashes instantly. If I run it without linking the scrollView to the outlet, it will run (allbeit with a blnk screen). The following is the error I get in the console: 2010-03-27 20:18:13.467 UseScrollViewViewController[7421:207] * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key scrollView.'

• Managing subviews in Cocoa Touch

  - by brainfsck

  Hi, I'm developing an iPhone app. I need to create a Quiz application that has different Question views embedded in it (see my similar question). Different types of Question will have different behavior, so I plan to create a controller class for each type of Question. The MultipleChoiceQuestionController would set up a question and 3-4 buttons for the user to select an answer. Similarly, the IdentifyPictureQuestionController would load an image and present a text box to the user. However, the docs say that a UIViewController should only be used for views that take up the entire application window. How else can I create a class to manage events in my subviews? Thanks,

• Cocoa structs and NSMutableArray

  - by Circle

  I have an NSMutableArray that I'm trying to store and access some structs. How do I do this? 'addObject' gives me an error saying "Incompatible type for argument 1 of addObject". Here is an example ('in' is a NSFileHandle, 'array' is the NSMutableArray): //Write points for(int i=0; i<5; i++) { struct Point p; buff = [in readDataOfLength:1]; [buff getBytes:&(p.x) length:sizeof(p.x)]; [array addObject:p]; } //Read points for(int i=0; i<5; i++) { struct Point p = [array objectAtIndex:i]; NSLog(@"%i", p.x); }

  hi, I am attempting to encrypt/decrypt a plain text file in my text editor. encrypting seems to work fine, but the decrypting does not work, the text comes up encrypted. I am certain i've decrypted the text using the word i encrypted it with - could someone look through the snippet below and help me out?

• Cocoa contentsOfDirectoryAtPath: method failing with error for certain users - Mac OS X

  - by Patrick

  Here's a snippet of the code: // Get into the data folder of it keychainPath = [keychainPath stringByAppendingPathComponent:@"data/default"]; DLog(@"Keychain data path: %@", keychainPath); // Define Filemanager NSFileManager *fm = [NSFileManager defaultManager]; // Catch any errors NSError *dataError = nil; // get all the files in the directory NSArray *dataFiles = [fm contentsOfDirectoryAtPath:keychainPath error:&dataError]; if(!dataFiles) NSLog(@"Error: %@",dataError); Now this works perfectly fine for most people, but a few have reported problems, with the 'dataError' object giving: Error: Error Domain=NSCocoaErrorDomain Code=260 UserInfo=0x14d1fa10 "The folder “default” doesn’t exist." Underlying Error=(Error Domain=NSOSStatusErrorDomain Code=-43 "The operation couldn’t be completed. (OSStatus error -43.)" (File not found)) The people having this problem have said that the file / folder 'default' DOES exist exactly where is should be, so I have no idea why this isn't working. Any help would be appreciated!

• How to get OpenGL to display NV12 texture in Cocoa

  - by ReachConnection

  I have a YUV:420 (aka NV12) frame data, how can I get OpenGL to recognize its format for glTexImage2D() rendering. I realize that I might have to perform colorspace transformation, but is there a way that I can tell openGl to command the graphic hardware to perform the colorspace transformation?

• Implementing touch-based rotation in cocoa touch

  - by ewoo

  I am wondering what is the best way to implement rotation-based dragging movements in my iPhone application. I have a UIView that I wish to rotate around its centre, when the users finger is touch the view and they move it. Think of it like a dial that needs to be adjusted with the finger. The basic question comes down to: 1) Should I remember the initial angle and transform when touchesBegan is called, and then every time touchesMoved is called apply a new transform to the view based on the current position of the finger, e.g., something like: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:self.middle] <= ROTATE_RADIUS //middle is centre of view && [Utility getDistance:currentPoint toPoint:self.middle] >= MOVE_RADIUS) { //will be rotation gesture //remember state of view at beginning of touch CGPoint top = CGPointMake(self.middle.x, 0); self.initialTouch = currentPoint; self.initialAngle = angleBetweenLines(self.middle, top, self.middle, currentPoint); self.initialTransform = self.transform; } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:self.middle] <= ROTATE_RADIUS && [Utility getDistance:currentPoint toPoint:self.middle] >= MOVE_RADIUS) { //a rotation gesture //rotate tile float newAngle = angleBetweenLines(self.middle, CGPointMake(self.middle.x, 0), self.middle, currentPoint); //touch angle float angleDif = newAngle - self.initialAngle; //work out dif between angle at beginning of touch and now. CGAffineTransform newTransform = CGAffineTransformRotate(self.initialTransform, angleDif); //create new transform self.transform = newTransform; //apply transform. } OR 2) Should I simply remember the last known position/angle, and rotate the view based on the difference in angle between that and now, e.g.,: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:self.middle] <= ROTATE_RADIUS && [Utility getDistance:currentPoint toPoint:self.middle] >= MOVE_RADIUS) { //will be rotation gesture //remember state of view at beginning of touch CGPoint top = CGPointMake(self.middle.x, 0); self.lastTouch = currentPoint; self.lastAngle = angleBetweenLines(self.middle, top, self.middle, currentPoint); } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:middle] <= ROTATE_RADIUS && [Utility getDistance:currentPoint toPoint:middle] >= MOVE_RADIUS) { //a rotation gesture //rotate tile float newAngle = angleBetweenLines(self.middle, CGPointMake(self.middle.x, 0), self.middle, currentPoint); //touch angle float angleDif = newAngle - self.lastAngle; //work out dif between angle at beginning of touch and now. CGAffineTransform newTransform = CGAffineTransformRotate(self.transform, angleDif); //create new transform self.transform = newTransform; //apply transform. self.lastTouch = currentPoint; self.lastAngle = newAngle; } The second option makes more sense to me, but it is not giving very pleasing results (jaggy updates and non-smooth rotations). Which way is best (if any), in terms of performance? Cheers!

• Cocoa Application with Menubar but no Dock Icon / switch menu

  - by Frank R.

  Hi, This is yet one more of those "how to switch from running with a dock icon to running without one" questions with a twist.. I don't want the dock icon but I do want a menu bar when the application is at the front. Is that possible? Running an application with LSUIElement set to 1 in the plist will launch the application without a dock icon, not showing up in the command-tab switch list and without a menu. You can switch from that mode to the "normal" mode with all three switched on via SetSystemModeUI from 10.2 onwards and via NSApplication setApplicationActivationPolicy since 10.6, but crucially there is no way back to the previous mode (go figure). So one way around this would be to launch with LSUIElement = 1 and then activate the menu bar when the application gets the focus and deactivate it on the application losing the focus.. alas I can't find a way of doing that. Can anybody help? Best regards, Frank

• Cocoa NSStream works with SSL, with socks5, but not at the same time

  - by Evan D

  Upon connecting (to an FTP, at first without SSL) I run: NSArray *objects = [NSArray arrayWithObjects:@"proxy.ip", [NSNumber numberWithInt:1080], NSStreamSOCKSProxyVersion5, @"user", @"pass", nil]; NSArray *keys = [NSArray arrayWithObjects:NSStreamSOCKSProxyHostKey, NSStreamSOCKSProxyPortKey, NSStreamSOCKSProxyVersionKey, NSStreamSOCKSProxyUserKey, NSStreamSOCKSProxyPasswordKey, nil]; NSDictionary *proxyDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys]; [iStream retain]; [iStream setDelegate:self]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [iStream setProperty:proxyDictionary forKey:NSStreamSOCKSProxyConfigurationKey]; [iStream open]; same for iStream. This allows me to connect succesfully through a socks5 proxy. If I continue without setProperty:proxyDictionary... (socks5 disabled) I would tell the server to switch to SSL, and then successfully apply these settings to the in/output streams, thus giving me a SSL connection: NSMutableDictionary *settings = [NSMutableDictionary dictionaryWithCapacity:1]; [settings setObject:(NSString *)NSStreamSocketSecurityLevelTLSv1 forKey:(NSString *)kCFStreamSSLLevel]; // to allow selfsigned certificates: [settings setObject:[NSNumber numberWithBool:YES] forKey:(NSString *)kCFStreamSSLAllowsAnyRoot]; [iStream retain]; [iStream setDelegate:self]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; CFReadStreamSetProperty((CFReadStreamRef)iStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings); [iStream setProperty:NSStreamSocketSecurityLevelTLSv1 forKey:NSStreamSocketSecurityLevelKey]; same for oStream. All of which works fine if I disable socks5. If I turn it on (line 7 in the first snippit) I lose contact when applying the SSL settings. If I had to guess, I'd think it's losing some properties when applying (ssl) "settings"? Please help :) Evan

• MVC with cocoa/objective-c

  - by Leonardo

  Hi all, I have a strong j2ee background, and I am trying to move to objective-c for some desktop/iphone programming. I used many java web frameworks with mvc in mind, spring and struts ecc... so I am used to have servlet or controller which pass attributes to jsp pages, which is the view. In jsp pages with jstl you can call this attribute and render to video. In this way controller and view are (in theory) clearly separated. With xcode, I can easily recognize the controller and the view built with IBuilder. All the tutorial I found, shown the controller which go and change directly labels or text fields. So my two questions: seems to me that there's no separation between the two (controller and view), where I am wrong in that ? is there a way for a controller to pack all objects in a kind of context in a j2ee way and have the view read that context ? thanks Leonardo

• Generate a random alphanumeric string in cocoa

  Hey there, I know this can't be that hard. I've searched, but I can't seem to find a simple solution. I want to call a method, pass it the length and have it generate a random alphanumeric string. Any ideas? Are there any utility libraries out there that may have a bunch of these types of functions? Thanks, Howie

• Cocoa - Enumerate mutable array, removing objects

  - by Ward

  Hey there, I have a mutable array that contains mutable dictionaries with strings for the keys latitude, longitude and id. Some of the latitude and longitude values are the same and I want to remove the duplicates from the array so I only have one object per location. I can enumerate my array and using a second enumeration review each object to find objects that have different ids, but the same latitude and longitude, but if I try to remove the object, I'm muting the array during enumeration. Is there any way to remove objects from an array while enumerating so I only enumerate the current set of objects as the array is updated? Hope this question makes sense. Thanks, Howie

  Hi, I've created a UIView (of type ColumnView) in Interface Builder. Is it possible to add that UIView multiple times to my window? I'm trying to create a UIView template that I can add to my window in a couple of places but can't figure out how to do that. I tried referencing the outlet of that UIView to 2 different IBOutlets but when I add the 2 outlets to my window, it's just treated as a single UIView. Need the UIView to be duplicated. Thanks, Tee

• cocoa Expected specifier-qualifier-list before struct

  - by Circle

  I read the other posted solutions to using structs and resolving the "Expected specifier-qualifier-list before struct" related errors, but those aren't working. Is it different in Objective C? Do I need to declare my struct somewhere else in the class? It gives me the error on the line where I declare the typedef. Here is how it looks right now: @interface ClassA : NSObject { NSString *name; typedef struct _point { uint32_t x; uint64_t y; } Point; Point a; } @end

• Cocoa Virtual Keystrokes Pain

  - by bhargav

  I'm writing an application to respond on a hotkey by copying highlighted text into NSPasteboard's generalPasteboard. After looking around here for a solution for sending virtual keystrokes, I found this: http://stackoverflow.com/questions/1505933/how-to-send-a-cmd-c-keystroke-to-the-active-application-in-objective-c-or-tell I tried the applescript suggested with NSAppleScript: NSLog(@"Hotkey Pressed"); NSPasteboard *pasteboard = [NSPasteboard generalPasteboard]; NSAppleScript *playScript; playScript = [[NSAppleScript alloc] initWithSource:@"tell application \"System Events\" to keystroke \"c\" using command down"]; if([playScript isCompiled] == NO){ [playScript compileAndReturnError:nil]; } id exerror = [playScript executeAndReturnError:nil]; if(exerror == nil){ NSLog(@"Script Failed"); } It works, but only on the first time I hit the hotkey. Each subsequent hit will not to grab the highlighted text. The generalPasteboard still contains the same contents as before the script is run again. Clearing the generalPasteboard before I run the code is no use, because then the code fails when attempting to read the pasteboard contents. So I tried the next suggested solution: CFRelease(CGEventCreate(NULL)); CGEventRef event1, event2, event3, event4; event1 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)50, true); event2 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)8, true); event3 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)8, false); event4 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)50, false); CGEventPost(kCGHIDEventTap, event1); CGEventPost(kCGHIDEventTap, event2); CGEventPost(kCGHIDEventTap, event3); CGEventPost(kCGHIDEventTap, event4); The above should send the keystrokes Command + c, but all I get is a beep, and the pasteboard contents are unchanged. I'm at wits end - can anyone enlighten me as to what I'm missing or point me out to what I'm overlooking for something so simple?

• Microphone audio streaming from Cocoa mac app to iPhone

  - by Benzamin

  Hi devs, I'm trying to build a microphone audio streamer to iPhone. The server software will be a mac desktop app and the client will be iPhone, and they are connected via tcp port. I've successfully connected the mac app and iPhone, and tried to send a fixed test.m4a audio file first. But at the iPhone i grabbed the data well, when tried to play it i used AVAudioPlayer and its returning OSStatus error. I played around with the audio queue service but its very tricky and i only got some example for fixed length audio playing like http://cocoawithlove.com/2009/06/revisiting-old-post-streaming-and.html Now i need help on two things, how can i continuously grab audio data from Mac desktop microphone? And then after grabbing the data how i can play this unfixed length audio data in the iPhone. What exactly i need to do? Please please help me on this......

• [Cocoa] NSTableView bound to NSArrayController

  - by ndg

  Within Interface Builder I've got an NSTableView with two columns bound to a vanilla NSArrayController. The NSArrayController has its Content Array bound to an NSMutableArray in my application delegate. I've used further bindings to setup the addition and removal of rows via bindings (magic!). The issue I'm running into now is that I'd like to grab the currently selected NSTableView row and use its index to look-up the object stored in my NSArrayControllers associated array. The problem I'm running into is trying to access the NSTableView. Within my application delegate, using the following code will cause my application to crash: NSLog(@"%@", [timersTableView selectedRow]); Similarly, this also causes my application to crash: NSLog(@"%@", [timersController selectionIndex]); Given the simplicity of the code above, I must be doing something fundamentally wrong?

• cocoa - making a UIImageView class act like a UIButton

  - by Mike

  For some reason that will take too much time to explain, I have to create a UIImageView based class that has some properties of a button. Imagine a class like the UISwitch (no I cannot base my class on the UISwitch) with two states, on and off. WHen the user selects one state, it runs a method like a button that was clicked and the method receives the sender id. I have already the class more or less working. The class is based on UIImageView. I am having difficulties to understand the following. WHen I create a new button I have a line that is like [myButton addTarget:self action:NSSelectorFromString(myMethod) forControlEvents:UIControlEventTouchUpInside]; This line defines a target and an action to run when the button is triggered. I my case I would need something like [myObject addTarget:self action:myMethod ifState:1] //or another thing ifState:2 I have no idea what kind of code I should put on the class to make this work. Remember that as a button the class should send the "sender" information to identify the object which triggered the action... Can you guys, transcendental gurus help? thanks for any help!

• NSStatusItem (cocoa) location on screen

  - by Craig

  I am trying to get the on screen location of an NSStatusItem so that I can perform a click on that area via code like below. I am doing this so that my users can press a hotkey to see the menu. event = CGEventCreateMouseEvent(NULL, kCGEventLeftMouseDown, newLocation, kCGMouseButtonLeft); CGEventPost(kCGHIDEventTap, event); CFRelease(event); Does anyone know of a way to get the location?, I have been trying ideas and searching for days and have found several ideas but none of them seem to work in leopard/snow leopard The NSStatusItem is using an NSMenu not a custom view.

• Cocoa QuickLook initiated by NSTableView Cell

  - by Tristan Seifert

  I have an NSTableView that contains 2 different Columns - one is an NSImageCell that shows a file icon, and the second is a custom subclass of NSTextFieldCell that contains a quick look button on the right of the text. When I click the Quick Look button, the following code is invoked: [[QLPreviewPanel sharedPreviewPanel] makeKeyAndOrderFront:nil]; This does it's job and shows the blank Quick Look panel saying "No Items Selected." After I did a bit of research on the internet, I implemented a custom NSTableView subclass to be the Delegate and Data Source for the Quick Look panel. I get the notification that Quick Look asks if I want to be the delegate, and I respond with return YES. Even though I implement all methods in both QLPreviewPanelDataSource and QLPreviewPanelDelegate, at runtime I get this error on the console: 2010-12-24 15:32:17.235 BackMeUp[4763:80f] clicked: ~/Desktop/HUDTape.mov 2010-12-24 15:32:17.489 BackMeUp[4763:80f] [QL] QLError(): -[QLPreviewPanel setDelegate:] called while the panel has no controller - Fix this or this will raise soon. See comments in QLPreviewPanel.h for -acceptsPreviewPanelControl:/-beginPreviewPanelControl:/-endPreviewPanelControl:. 2010-12-24 15:32:17.490 BackMeUp[4763:80f] [QL] QLError(): -[QLPreviewPanel setDataSource:] called while the panel has no controller - Fix this or this will raise soon. See comments in QLPreviewPanel.h for -acceptsPreviewPanelControl:/-beginPreviewPanelControl:/-endPreviewPanelControl:. 2010-12-24 15:32:17.491 BackMeUp[4763:80f] We can now receive QL Events. 2010-12-24 15:32:18.291 BackMeUp[4763:80f] -[NSPathStore2 stringValue]: unrecognized selector sent to instance 0x5ecb10 2010-12-24 15:32:18.292 BackMeUp[4763:80f] -[NSPathStore2 stringValue]: unrecognized selector sent to instance 0x5ecb10 And the Quick Look panel does not show up, which I find rather odd. The first line above is just that I know the cell has been clicked. Anyways, here is the .m file of the custom table view subclass: // // BackupListTableView.m // BackMeUp // // Created by Tristan Seifert on 12/24/10. // Copyright 2010 24/7 Server.
