  • Getting Console Logs for My Cocoa App

    - by enchilada
    I'm making a crash reporter, and I can read the crash reporter files just fine within ~/Library/Logs/CrashReporter. However, I want to also send along with the report any console (NSLog) information that was printed to the console (the stuff that one can see both in Xcode and in Console.app). However, I want to make sure I get only the logs for my app. I don't want logs from other apps. How does one get the console logs for a specific app?

  • Showing value of UISlider inside App Prefs?

    - by Garrett H
    I have a settings bundle, working perfectly, that I would like to customize a bit. I have, among other things, a PSSliderSpecifier and a PSTitleValueSpecifier. What I would like to do is change the value of the PSTitleValueSpecifier to show the current value of the slider, preferably updating every time the slider's value changes (Actually, what I'd like even more would be displaying the slider's value on the same row as the slider). I know the settings bundle is rather strict about what you're allowed to do in it, but is there any way of doing this?

  • Cocoa - NSFileManager removeItemAtPath Not Working

    - by Kevin
    Hey there everyone, I am trying to delete a file, but somehow nsfilemanager will not allow me to do so. I do use the file in one line of code, but once that action has been ran, I want the file deleted. I have logged the error code and message and I get error code: 4 and the message: "text.txt" could not be removed Is there a way to fix this error "cleanly" (without any hacks) so that apple will accept this app onto their Mac App Store? EDIT: This is what I am using: [[NSFileManager defaultManager] removeItemAtPath:filePath error:NULL]; Thanks, kevin

  • iPhone: Using dispatch_after to mimick NSTimer

    - by Joseph Tura
    Don't know a whole lot about blocks. How would you go about mimicking a repeating NSTimer with dispatch_after? My problem is that I want to "pause" a timer when the app moves to the background, but subclassing NSTimer does not seem to work. I tried something which seems to work. I cannot judge its performance implications or whether it could be greatly optimized. Any input is welcome. #import "TimerWithPause.h" @implementation TimerWithPause @synthesize timeInterval; @synthesize userInfo; @synthesize invalid; @synthesize invocation; + (TimerWithPause *)scheduledTimerWithTimeInterval:(NSTimeInterval)aTimeInterval target:(id)aTarget selector:(SEL)aSelector userInfo:(id)aUserInfo repeats:(BOOL)aTimerRepeats { TimerWithPause *timer = [[[TimerWithPause alloc] init] autorelease]; timer.timeInterval = aTimeInterval; NSMethodSignature *signature = [[aTarget class] instanceMethodSignatureForSelector:aSelector]; NSInvocation *aInvocation = [NSInvocation invocationWithMethodSignature:signature]; [aInvocation setSelector:aSelector]; [aInvocation setTarget:aTarget]; [aInvocation setArgument:&timer atIndex:2]; timer.invocation = aInvocation; timer.userInfo = aUserInfo; if (!aTimerRepeats) { timer.invalid = YES; } [timer fireAfterDelay]; return timer; } - (void)fireAfterDelay { dispatch_time_t delay = dispatch_time(DISPATCH_TIME_NOW, self.timeInterval * NSEC_PER_SEC); dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0); dispatch_after(delay, queue, ^{ [invocation performSelectorOnMainThread:@selector(invoke) withObject:nil waitUntilDone:NO]; if (!invalid) { [self fireAfterDelay]; } }); } - (void)invalidate { invalid = YES; [invocation release]; invocation = nil; [userInfo release]; userInfo = nil; } - (void)dealloc { [self invalidate]; [super dealloc]; } @end

  • Can I avoid explicitly casting objects with a common subclass?

    - by prendio2
    I have an iPodLibraryGroup object and Artist and Album both inherit from it. When it comes to my view controllers though I find that I'm duplicate lots of code, for example I have an ArtistListViewController and and AlbumListViewController even though they're both doing basically the same thing. The reason I've ended up duplicating the code is because these view controllers each refer to either an Artist object or al Album object and I'm not sure how to set it up so that one view controller could handle both — these view controllers are mainly accessing methods that that the objects have in common from iPodLibraryGroup. As an example, to hopefully make this clearer consider this code in AlbumListViewController: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { Album *album = nil; album = [self albumForRowAtIndexPath:indexPath inTableView:tableView]; … if (!album.thumbnail) { [self startThumbnailDownload:album forIndexPath:indexPath inTableView:tableView]; cell.imageView.image = [UIImage imageNamed:@"Placeholder.png"]; } else { cell.imageView.image = album.thumbnail; } return cell; } This is essentially completely repeated (along with a hell of a lot more repeated code) in ArtistListViewController just so that I can typecast the local variable as an Artist instead of an Album. Is there a way to not explicitly need to set Artist or Album here so that the same code could work for any object that is a child of iPodLibraryGroup?

  • 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!

  • How to get call notification using mobile substrate on iphone?

    - by prathumca
    Hi all, I want to use mobile substrate to "hook" some code into IPhone's "MobileCal" app so that the injected code will send a notification to my app MobileCal gets a call notification. But I'm out of luck and no clue which method need to be replaced by my "hooking" method in the "MobileCal" app. For example, the "MobileLog" and "iRealSMS" has the same functionality and they used mobile substrate to hook their code into "MobileCal" app. If any one has any clue, I would definitely appreciate them.

  • Pass through touches to portion of UIWebView

    - by cannyboy
    I have a UIWebView. Using something like this: http://blog.evandavey.com/2009/02/how-to-make-uiwebview-transparent.html .. I have made the UIWebView transparent. I now need to be able to pass though touches on the webview to the view below, but only on a rectangular portion of the web view. So, imagine the webview is a square, and it has a square area in the centre which must pass-thru touches to the view below. Is there a way to do this?

  • Cocoa window position anomaly

    - by Marius
    Hello everyone, I have a weird problem with positioning a window on screen. I want to center the window on the screen, but i don't know how to do that. Here's what i've got. The window is created from nib by the main controller: IdentFormController *ftf = [[IdentFormController alloc] initWithWindowNibName:@"IdentForm"]; [[ftf window] makeKeyAndOrderFront:self]; Now the IdentFormController has awakeFromNib() method in which it tries to position the window. For the sake of simplicity i've just tried to do setFrameOrigin(NSMakePoint(0, 0)). What happens is as follows: The first time i create this window, everything works as expected. But if i create it again after releasing the previous, it starts appearing at random positions. Why does it do that?

  • Creating iPhoto albums using Cocoa Scripting Bridge

    - by robinjam
    I'm tearing my hair out trying to create a new album from a Cocoa Application. In applescript it's a nice simple procedure: tell application "iPhoto" new album name "Album" end tell But I can't work out how this is done in Cocoa via the Scripting Bridge. I've tried this: iPhotoApplication *iPhoto = [SBApplication applicationWithBundleIdentifier:@"com.apple.iPhoto"]; iPhotoAlbum *newAlbum = [[[[iPhoto classForScriptingClass:@"album"] alloc] initWithProperties:[NSDictionary dictionaryWithObject:@"Album" forKey:@"name"]] autorelease]; [[iPhoto albums] addObject:newAlbum]; But that had no effect. Please help!

  • Long polling with NSURLConnection

    - by pix0r
    I'm working on an iPhone application which will use long-polling to send event notifications from the server to the client over HTTP. After opening a connection on the server I'm sending small bits of JSON that represent events, as they occur. I am finding that -[NSURLConnectionDelegate connection:didReceiveData] is not being called until after I close the connection, regardless of the cache settings I use when creating the NSURLRequest. I've verified that the server end is working as expected - the first JSON event will be sent immediately, and subsequent events will be sent over the wire as they occur. Is there a way to use NSURLConnection to receive these events as they occur, or will I need to instead drop down to the CFSocket API? I'm starting to work on integrating CocoaAsyncSocket, but would prefer to continue using NSURLConnection if possible as it fits much better with the rest of my REST/JSON-based web service structure.

  • Why can't I save changes to application settings with NSUserDefaults?

    - by Brennan
    I am using the following code to save values from a settings view that takes values from a UITextField and stores them with NSUserDefaults. The code below even calls synchronize yet it is not saving the changes. What am I doing wrong here? - (IBAction)save { NSLog(@"save"); NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; if (self.usernameTextField.text != nil) { NSLog(@"username: %@", self.usernameTextField.text); [defaults setObject:kTwitterUsernameKey forKey:self.usernameTextField.text]; } if (self.passwordTextField.text != nil) { NSLog(@"password: %@", self.passwordTextField.text); [defaults setObject:kTwitterPasswordKey forKey:self.passwordTextField.text]; } [defaults synchronize]; [self dismissModalViewControllerAnimated:TRUE]; }

  • Getting random objects from an array, and if the objects are the same, get a new object.

    - by XcodeDev
    Hi, I have made a jokes application, where the user generates a joke and the joke will display in a UILabel. However I am trying to randomise the jokes show, but I do not want to show the same joke twice. Please could you tell me how I could do this. I am using the code below to try and do that, but it seems that it is not working. - (IBAction)generateNewJoke { if (i < [jokeArray count]) { i++; [userDefaults setInteger:[userDefaults integerForKey:kNewIndex] forKey:kOldIndex]; int oldnumber = [userDefaults integerForKey:kOldIndex]; int newnumber = [userDefaults integerForKey:kNewIndex]; [answerLabel setText:@""]; [userDefaults setInteger:i forKey:kNewIndex]; if (oldnumber == newnumber) { NSLog(@"they are the same"); [userDefaults setInteger:arc4random()%[jokeArray count] forKey:kNewIndex]; } [jokeLabel setText:[jokeArray objectAtIndex:[userDefaults integerForKey:kNewIndex]]]; } }

  • What can I read from the iPad Camera Connection Kit?

    - by HELVETICADE
    I'm building a small controller device that I'd like to partner with a computer. I've settled on using OSC out from my custom built hardware and am pretty satisfied with what I can get from WOscLib. Two goals I'd like to achieve are portability and a very ratio between battery:computing power, and this has lured me towards using iPhoneOS to accomplish my goals. I think the iPad would suit my needs perfectly, except that using wifi to broadcast OSC out from my device requires a third device and would destroy the goal of portability, whilst also introducing potential latency and stability headaches. My question is pretty simple: Can I push my OSC-out FROM my controller TO an iPad via USB and the Camera Connection Kit? If I could accomplish this, the two major goals of my project would be fulfilled very nicely. This seems like it should be a simple little question, but researching this obsessively over the past few weeks has left me more almost more uncertain than if I had done no research at all. I'd really like some more confidence before I go down this route, and it seems like it should be possible. Any insight would be very, very appreciated.
