  • Applescript from Mac App says "Expected end of line but found \U201c\"\U201d."

    - by Rasmus Styrk
    I am trying to perform a copy/paste for my to the the last active app, here's my code: NSString *appleScriptSource = [NSString stringWithFormat:@"\ntell application \"%@\" to activate\ntell application \"System Events\" to tell process \"%@\"\nkeystroke \"v\" using command down\nend tell", [lastApp localizedName], [lastApp localizedName]]; NSDictionary *error; NSAppleScript *aScript = [[NSAppleScript alloc] initWithSource:appleScriptSource]; NSAppleEventDescriptor *aDescriptor = [aScript executeAndReturnError:&error]; The problem is that on some computers it works just fine, but on others it fails. My error output from error that is returned by executeAndReturnError is: 2012-06-13 17:43:19.875 Mini Translator[1206:303] (null) (error: { NSAppleScriptErrorBriefMessage = "Expected end of line but found \U201c\"\U201d."; NSAppleScriptErrorMessage = "Expected end of line but found \U201c\"\U201d."; NSAppleScriptErrorNumber = "-2741"; NSAppleScriptErrorRange = "NSRange: {95, 1}"; }) I can't seem to figure out what it means or why it happens. We tried copying the generated apple-script code into the Apple Script editor, and here it works just fine. My App is sandboxed - i have added the bundle identifiers for the key "com.apple.security.temporary-exception.apple-events" for the apps i want to support. Any suggestions?

  • Is this a good KVO-compliant way to model a mutable to-many relationship?

    - by andyvn22
    Say I'd like a mutable, unordered to-many relationship. For internal optimization reasons, it'd be best to store this in an NSMutableDictionary rather than an NSMutableSet. But I'd like to keep that implementation detail private. I'd also like to provide some KVO-compliant accessors, so: - (NSSet*)things; - (NSUInteger)countOfThings; - (void)addThings:(NSSet*)someThings; - (void)removeThings:(NSSet*)someThings; Now, it'd be convenient and less evil to provide accessors (private ones, of course, in my implementation file) for the dictionary as well, so: @interface MYClassWithThings () @property (retain) NSMutableDictionary* keyedThings; @end This seems good to me! I can use accessors to mess with my keyedThings within the class, but other objects think they're dealing with a mutable, unordered (, unkeyed!) to-many relationship. I'm concerned that several things I'm doing may be "evil" though, according to good style and Apple approval and whatnot. Have I done anything evil here? (For example, is it wrong not to provide setThings, since the things property is supposedly mutable?)

  • Replacing text in NSTextFieldCell inside NSTableView

    - by earl.ct
    Whenever a user would type a number, my app would automatically prepend a currency sign before that number. For example, when the user types "1" in a text field, the text inside it becomes "$1.00". All is good when I use an NSNumberFormatter, an NSTextField, and its delegate method control:didFailToFormatString:errorDescription:. - (BOOL)control:(NSControl *)control didFailToFormatString:(NSString *)string errorDescription:(NSString *)error { if ([[control formatter] isKindOfClass:[NSNumberFormatter class]]) { NSNumberFormatter *formatter = [control formatter]; if ([formatter numberStyle] == NSNumberFormatterCurrencyStyle && ! [string hasPrefix:[formatter currencySymbol]]) { NSDecimalNumber *new = [NSDecimalNumber decimalNumberWithString:string]; if (new == [NSDecimalNumber notANumber]) { new = [NSDecimalNumber zero]; } [control setObjectValue:new]; } } return YES;} Now I would like to have this functionality when a user types a number in a cell inside an NSTableView. I tried using control:didFailToFormatString:errorDescription: but the cell would erase the text instead.

  • create custom pdf viewer for iphone

    - by Ankit Sachan
    I want to develop a custom pdf viewer, in which I can add features like: bookmarks jump to specific page take some notes page flipping effect Can you suggest some libraries in Cocoa touch to fullfill my requirements? I followed the PDF viewing tutorial in which a webview was used but it only provides basic scrolling and zoom facilities. I have seen some apps in which bookmarks and page flipping is possible. Kindly suggest me something so that I can integrate more features.

  • What is NSString in struct?

    - by 4thSpace
    I've defined a struct and want to assign one of its values to a NSMutableDictionary. When I try, I get a EXC_BAD_ACCESS. Here is the code: //in .h file typedef struct { NSString *valueOne; NSString *valueTwo; } myStruct; myStruct aStruct; //in .m file - (void)viewDidLoad { [super viewDidLoad]; aStruct.valueOne = @"firstValue"; } //at some later time [myDictionary setValue:aStruct.valueOne forKey:@"key1"]; //dies here with EXC_BAD_ACCESS This is the output in debugger console: (gdb) p aStruct.valueOne $1 = (NSString *) 0xf41850 Is there a way to tell what the value of aStruct.valueOne is? Since it is an NSString, why does the dictionary have such a problem with it? ------------- EDIT ------------- This edit is based on some comments below. The problem appears to be in the struct memory allocation. I have no issues assigning the struct value to the dictionary in viewDidLoad, as mentioned in one of the comments. The problem is that later on, I run into an issue with the struct. Just before the error, I do: po aStruct.oneValue Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000000 0x9895cedb in objc_msgSend () The program being debugged was signaled while in a function called from GDB. GDB has restored the context to what it was before the call. To change this behavior use "set unwindonsignal off" Evaluation of the expression containing the function (_NSPrintForDebugger) will be abandoned. This occurs just before the EXC_BAD_ACCESS: NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:@"MM-dd-yy_HH-mm-ss-A"]; NSString *date = [formatter stringFromDate:[NSDate date]]; [formatter release]; aStruct.valueOne = date; So the memory issue is most likely in my releasing of formatter. The date var has no retain. Should I instead be doing NSString *date = [[formatter stringFromDate:[NSDate date]] retain]; Which does work but then I'm left with a memory leak.

  • MVC model flow?

    - by fuzzygoat
    I am setting up an application using the MVC model and I have a query regrading the flow of information from the UI to the data model. What I need to do is place data from the UI in the model, what I have done is write a method in the view which collects the required data in an object and then passes it to the model. The model then takes ownership of the data so that the view can release its ownership. Does this sound sensible?

  • iPhone SDK: How to generate a random time of day

    - by bigdave
    Hello all, I am having some problems trying to figure out the best way of generating a random time of day. For instance, if I want to choose a random time between the hours of 9am and 5pm, what would be the best way with the least amount of overhead on the device? I guess I need someone to point me in the right direction. Thanks!

  • iPhone Dev: Animating PNG Sequences

    - by Franky
    What is the best or recommended technique for animating PNG Sequences. Heres what I've learned: Do it Manually Using MutableArrays containing Strings, you can animate a UIImageView with a timer which increments an index number UIImage - animation methods This works, the only problem is to find if an image has completed its animation, you have to check the isAnimating BOOL, and to do that you need a timer. What is the best and recommended? Looking to do Oldschool game sprite animations, ie: Idle Animation Attack Animation Walk Animation ect... Let me know if any one has something. @lessfame

  • Another IKImageView Question: copying a region

    - by Brian Postow
    I'm trying to use the select and copy feature of the IKImageView. If all you want to do is have an app with an image, select a portion and copy it to the clipboard, it's easy. You set the copy menu pick to the first responder's copy:(id) method and magically everything works. However, if you want something more complicated, like you want to copy as part of some other operation, I can't seem to find the method to do this. IKImageView doesn't seem to have a copy method, it doesn't seem to have a method that will even tell you the selected rectangle! I have gone through Hillegass' book, so I understand how the clipboard works, just not how to get the portion of the image out of the view... Now, I'm starting to think that I made a mistake in basing my project on IKImageView, but it's what Preview is built on (or so I've read), so I figured it had to be stable... and anyway, now it's too late, I'm too deep in this to start over... So, other than not using IKImageView, any suggestions on how to copy the select region to the clipboard manually? EDIT actually, I have found the copy(id) method, but when I call it, I get <Error>: CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 16 bits/pixel; 1-component color space; kCGImageAlphaPremultipliedLast; 2624 bytes/row. Which obviously doesn't happen when I do a normal copy through the first-responder... I understand the error message, but I'm not sure where it's getting those parameters from... Is there any way to trace through this and see how this is happening? A debugger won't help for obvious reasons, as well as the fact that I'm doing this in Mozilla, so a debugger isn't an option anyway... EDIT 2 It occurs to me that the copy:(id) method I found may be copying the VIEW rather than copying a chunk of the image to the clipboard, which is what I need. The reason I thought it was the clipboard copy is that in another project, where I'm copying from an IKImageView to the clipboard straight from the edit menu, it just sends a copy:(id) to the firstResponder, but I'm not actually sure what the firstresponder does with it...

  • NSOutlineView/NSTreeController - calculate sum of column

    - by matei
    I have a NSOutlineView bound to a NSTreeController. My data items are a custom class , let's call them "Row", and suppose a Row contains a "name" and a numeric field called "number" . All these "Rows" are found in let's say a "RowContainer" which has a "rows" mutable array holding the parent (level 0) rows. Each row also has a "children" NSMutableArray member which holds it's children. I have this working, and I want to display under the outlineview a textfield with the sum of all the "number" values of the rows. I bound this textfield to a "total" property of the "RowContainer". Now the problem is how or from where to trigger the recalculation of the "total" property, since this involves a recursive walk on the tree of rows, and I always get a "Collection was mutated while being enumerated" error. I've tried making a method "recalculateTotal", and calling it from the "setNumber" method of the "Row" class , but same error occurs. If I put the recalculation logic in the "total" getter, I can't trigger it to do the math. I'm sure the solution is simple but I can't see it

  • Location of the object after scrolling in UIScrollView

    - by ludo
    Hi, I have a scrollView (width:320px height:100px) on my UIView, inside it I add 10 images with width:106.5px each. After that I use this function to have 3 different parts inside my scrollView, so everytime I scroll, an image will automatically be center. -(void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate { [self returnToPosition:self.scrollView]; } -(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { [self returnToPosition:self.scrollView]; } -(void)returnToPosition:(UIScrollView *)scrollView { CGFloat itemWidth = 106.5f; CGFloat position = [self.scrollView contentOffset].x; CGFloat newPosition = 0.0f; CGFloat offSet = position / itemWidth; NSUInteger target = (NSUInteger)(offSet + 0.5f); newPosition = target * itemWidth; [self.scrollView setContentOffset:CGPointMake(newPosition, 0.0f) animated:YES]; } Here is my question, I want to be able to know which image will be in the middle position after the user scroll the View, because I want to display on my UIView a text, specific to that image. But I don't know how to do that. Some Ideas?

  • UIViewControllers - TabBarApplication - iPhone SDK

    - by Kevin
    Hello everyone, I am very new to the iPhone SDK. I need to know if in a tab bar application I need to make UIViewController classes. For example, when I make a new tab bar application there is a default FirstViewController class (.h, .m) already there. Now if I have code on the second tab, would I need to create a SecondViewController class? If not, how would I make a button on the 2nd tab, and make that button do something. I'm not really sure how to do it, because the FirstViewController works with the buttons and code, but if I make a SecondViewController, and I link everything my app crashes. If anyone could help it would be greatly appreciated. Kevin

  • CMBufferQueueCreate fail, required parameters?

    - by Agustin
    Reading the documentation about iOS SDK CMBufferQueueCreate, it says that getDuration and version are required, all the others callbacks can be NULL. but running the following code: CFAllocatorRef allocator; CMBufferCallbacks *callbacks; callbacks = malloc(sizeof(CMBufferCallbacks)); callbacks->version = 0; callbacks->getDuration = timeCallback; callbacks->refcon = NULL; callbacks->getDecodeTimeStamp = NULL; callbacks->getPresentationTimeStamp = NULL; callbacks->isDataReady = NULL; callbacks->compare = NULL; callbacks->dataBecameReadyNotification = NULL; CMItemCount capacity = 4; OSStatus s = CMBufferQueueCreate(allocator, capacity, callbacks, queue); NSLog(@"QUEUE: %x", queue); NSLog(@"STATUS: %i", s); with timeCallback: CMTime timeCallback(CMBufferRef buf, void *refcon){ return CMTimeMake(1, 1); } and queue is: CMBufferQueueRef* queue; queue creations fails (queue = 0) and returns a status of: kCMBufferQueueError_RequiredParameterMissing = -12761, The callbacks variable is correctly initialized, at least the debugger says so. Somebody have played arround with CMBufferQueue? google doesn't know about that! Thanks

  • Presenting a Popover From a Rect Problem

    - by Sheehan Alam
    I have a UITableViewCell that has some labels and images that can be clicked. I want to present a popover whenever a user clicks on any part of the cell. How can I achieve this without interfering with the click actions of the labels & images? I am currently creating an invisible button ontop of some other clickable items in the cell and calling the popover: [replyPopover presentPopoverFromRect:CGRectMake(77, 25, 408, 68) inView:self permittedArrowDirections: UIPopoverArrowDirectionDown animated:YES]; Unfortunately, because the button is on top of the labels & images I am unable to click them. How can I show a popover by clicking on the background of a cell, so that there is no interference when clicking images & labels inside the cell?

  • Crashing the OS X Pasteboard

    - by Ben Packard
    I have an application that reads in text by emulating CMD-C copy commands and reading the pasteboard - unfortunately this the only way to achieve what I need. Occasionally, something goes wrong in execution (not sure yet if it's related to the copy command or not) and the app crashes. Once in a while, this has a knock on effect on the system-wide pasteboard - any other application that is running will crash if I attempt a copy, cut, or paste. Is there a robust way to handle this - something I should be doing with the NSPasteboard before exiting? Any information on what might be happening is appreciated. For completeness, here are the only snippets of code that access the pasteboard: Reading from the pasteboard: NSString *pBoardText = [[NSPasteboard generalPasteboard]stringForType:NSStringPboardType]; Initially clearing the pasteboard (I run this only once, at launch): [[NSPasteboard generalPasteboard] declareTypes: [NSArray arrayWithObject:NSStringPboardType] owner: self]; [[NSPasteboard generalPasteboard] setString: @"" forType: NSStringPboardType];

  • Apple Push Notifications With Foreign Accent Characters Not Receiving

    - by confeng
    I'm sending push notifications and when the message contains foreign characters (Turkish in my case) like I, s, ç, g... The message does not arrive to devices. Here's my code: $message = 'THIS is push'; $passphrase = 'mypass'; $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', 'MyPemFile.pem'); stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase); // Open a connection to the APNS server $fp = stream_socket_client( 'ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx); if (!$fp) exit("Failed to connect: $err $errstr" . PHP_EOL); echo 'Connected to Apple service. ' . PHP_EOL; // Encode the payload as JSON $body['aps'] = array( 'alert' => $message, 'sound' => 'default' ); $payload = json_encode($body); $result = 'Start'.PHP_EOL; $tokenArray = array('mytoken'); foreach ($tokenArray as $item) { // Build the binary notification $msg = chr(0) . pack('n', 32) . pack('H*', $item) . pack('n', strlen($payload)) . $payload; // Send it to the server $result = fwrite($fp, $msg, strlen($msg)); if (!$result) echo 'Failed message'.PHP_EOL; else echo 'Successful message'.PHP_EOL; } // Close the connection to the server fclose($fp); I have tried encoding $message variable with utf8_encode() but the message received as "THÝS is push". And other ways like iconv() didn't work for me, some of them cropped Turkish characters, some didn't receive at all. I also have header('content-type: text/html; charset: utf-8'); and <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> in my page. I don't think the problem appears while I set the value but maybe with pack() function. Any ideas to solve this without replacing characters with English?
