I'd like to make a rich text type editor using Core Text (ideally for iPad but I'm pretty sure I can't get iPad specific examples due to the NDA) I have no idea really where to start. I'd like to keep the interaction models without having to rewrite them, so would I be layering stuff on top of a text view? Then how do I keep the overlay...
Are there any good guides on how to use pubsub.framework? Apple's documentation is scarce and the sample code that they give you is impossible to follow ...
Could someone please explain how to go about getting the values passed to a non-existant method that is being intercepted when using: + (void)forwardInvocation:(NSInvocation *)anInvocation; + (NSMethodSignature *)methodSignatureForSelector:(SEL)aSelector; Given a message like: [SomeClass doSomething:@"theThing" withSomething:@"aPar...
How can I get the number of times an NSString (for example, @"cake") appears in a larger NSString (for example, @"Cheesecake, apple cake, and cherry pie")? I need to do this on a lot of strings, so whatever method I use would need to be relatively fast. Thanks! ...
Hi, I am developing an application in cocoa which needs to copy a set of files to the system folder. When copying files to system folder I am getting a "Permission denied " error message . How can I resolve this problem. Please any one help me... Thanks in advance ...
I have an application I want to bundle (with some additional files) together inside a wrapper application. Literally the only thing I want to do is have the wrapper application launch a resource file (i.e. as if I'd typed: /path/to/Resources/Bundled.app/Contents/MacOS/executable into the terminal. Make sense? I thought this should b...
Hi... I am just starting with OSX development, and I am trying to get delegate notifications from a NSTextField. I've got the following code so far: This is where I set the delegate: - (void) awakeFromNib { NSLog(@"Setting delegate"); [amountField setDelegate: [[TextfieldController alloc] initWithLog]]; } And this is my Text...
I am looking for a method exactly like -[NSWorkspace iconForFile:] but which returns the icon in a higher resolution if possible. In particular, I have an app which makes use of QuickLook to display previews of files, and I'd like it to fall back to the file icon if no quick look plugin is available. Using the iconForFile: method, howe...
The CurrencyConverter sample Cocoa application uses unformatted text fields in the interface, and pulls the values using floatValue in the controller. I added a formatter (to Currency) to the input dollar amount field, but this breaks the application. I'm just learning Cocoa, and am assuming "floatValue" cannot handle the $ sign at the...
Hi. I have a NSStatusItem and I want to popup a menu by rightclicking the item. I subclassed a NSView and overwrote the - (void)rightMouseDown:(NSEvent *)event method. I also implemented - (void)mouseDown:(NSEvent *)event for looking at the modifierflags. My problem is, that the view does not recieve the NSRightMouseDown-Event. And I don...

I just began to work with Objective-C and I'm managing pretty well. My last challenge was to make a command line utility, which I could than use in AppleScript. But my code does not work, not in the terminal, not in the AppleScript. So I'm asking you, what's the error in this peace of code, that should be very plain and easy? int main(i...
I am looking for a way (public or otherwise) to get an NSView, NSImage, CGImageRef, etc that shows the QuickLook preview for a file. Essentially the equivalent of QLThumbnailImageCreate() but for the preview. The public APIs I can find do not support this. They allow the creation of a thumbnail image or a QLPreviewPanel. The panel do...
I want to open an OpenGL window ( to display and grab keystrokes / mouse events ) in MacOSX. I don't want to use Glut (since it demandds it be the root thread). I don't want to learn Objective C. Is there anyway to access the OpenGL api in pure C? Thanks! ...
So my problem is that I have a NSManagedObject 'A' which has a has-many relationship to 'b'. So for each object of 'A', there can be many 'b'. Now, I want to make a copy of 'b', so that 'b' can be modified, but not saved to the store, but 'A' can be saved'. For example, self.title = A.name; setOfB = A.setOfb; // This is still managed...
I am writing an API that wraps some core foundation web functionality that can return a number of possible error conditions. I am struggling with deciding the best way to handle error conditions that the API consumer should deal with (like network timeouts, receiving unexpected results, malformed XML, etc). I have come up with 3 differen...

Hey, I didn't see this anywhere in their FAQ and wanted to know if EDMessage.framework [ http://www.mulle-kybernetik.com/software/EDFrameworks/ ] is thread safe. If it matters, I'd be sending out bulk quantities of html emails. I am currently sending each email one at a time on a non-main thread. Also, from the looks of the info on it...

The byte size I get perfectly matches the byte size as reported in...
