When I resize the window, the table will be resize as well but the "Amount" is the column that gets span wider.

I'm in the midst of debugging an extremely unusual problem, and I was wondering if anybody might have any insight into what might be going wrong: In a controller class from a NIB, I take an NSPanel from that same NIB, and then show it app modally on an NSWindow (that was created by hand in code): [[NSApplication sharedApplication] begi...
I'm working on a document-based application, and I want to use a document package as my file format. To do that, it seems that the NSDocument method I need to override is -writeToURL:ofType:error:. It sometimes works, but only under certain conditions. For example, this code works: - (BOOL)writeToURL:(NSURL *)absoluteURL ofType:(NSStri...
Let's say I have a method with this signature: -(void)plotPoly:(Polygon *)poly WithColor:(UIColor *)color AndFill:(BOOL)filled; How do I get that UIColor and BOOL in there as well as the Polygon? Should I wrap them in a NSArray and pull them out inside the called method? That would mean I have to change the method sig, right? Is th...
I thought it would be simpler to find if an object in on a dictionary, but it appears it is not. I have a NSMutableDictionary with just one key named "products". I have several products added to the dictionary dynamically, using something like [myDict addObject:@"banana" forKey:@"products"]; [myDict addObject:@"orange" forKey:@"produc...
I'm writing a program that involves playing back sine waves and combinations of sine waves... it must run on Mac, and I'm looking for a simple API that I can use. I'm open to ObjC, C, C++, Ruby, Python, etc.... I don't care what language as long as it's just a few lines of code. But Ruby would be nice :-) On Linux you can write to /dev/...

How would I send a Selector to another class? I know to send it to a selector in the same file you do [self performSelector:@selector(doSomething)]; and for sending it to another class I've tried [otherClass performSelector:@selector(doSomethingElse)]; But I just get an error in the Debugger saying +[otherClass doSomethingElse]:...
There are a number of bad ways to go about what I want to do, but this seems like one of those cases of "there must be a better way". I am using an MKMapView in an iPhone app that displays a number of annotations. Pretend for conceptual discussion that each town in a US state has an annotation, so there's a fairly dense pile of annotati...
I have a class (colorClass) which holds 2 NSStrings (idNumber and favoriteColor). There is an NSMutableArray (arrayColor) that holds over 50,000 colorClass objects. What is the fastest way to find all duplicate idNumbers from all colorClass objects and return them in an array? Right now I'm using 1 for loop that goes copies arrayColor...
In my little cocoa application I have bound the properties of a class to some text fields with help of a NSObjectController. The only problem I have so far: you always have to leave a text field before the NSObjectController updates the class with the current input. This becomes a problem if the user doesn't leave a texfield and clicks ...

Hi all, How would I write a code that would set the gradient level to 50%? It's pretty straight forward, but I'm not using an NSSlider so it just needs to be dropped down to 50% or anywhere around there. Thanks Kevin ...
I have an in memory managed object context called importMoc that I use to import records (e.g. employees). I have parsed a file and set up the employee objects in importMoc with one very important exception. The user confirms they want to process %d employees but I can't quite figure out how or when to set the "parent" relationship of th...
I have a situation where I want to map a pair of objects to a dictionary of information. I'd like to avoid creating an NSDictionary of NSDictionaries of NSDictionaries since that's simply confusing and difficult to maintain. For instance if I have two classes, Foo and Bar, I want {Foo, Bar} -> {NSDictionary} Are there other options th...
Hi there, I'm still learning, and I'm just stuck. I want the user to enter any number and in result, my program will do this equation: x = 5*y (y is the number the user adds, x is outcome) How would I do this? I'm not sure if I'm suppose to add in an int or NSString. Which should I use, and should I enter anything in the header file...
