Hi, I'm creating an app using the SmallSockets library ( http://smallsockets.sourceforge.net/ ). I have this code: #import "MAController.h" #import "Socket.h" @implementation MAController - (IBAction)doRequest:(id)sender { //Initialize NSURL *uUrl = [[NSURL alloc] initWithString:[tfHost stringValue]]; int ...
Can I intercept a method call in Objective-C? How? Edit: Mark Powell's answer gave me a partial solution, the -forwardInvocation method. But the documentation states that -forwardInvocation is only called when an object is sent a message for which it has no corresponding method. I'd like a method to be called under all circumstances, ev...

Hi Im building an app that will use a Core Data model. I pretty new at Objective C and my usual design patterns does not really apply on Core Data and Objective C, at least I can't seem to find examples that confirms they will. I have been through the Apple Developer examples and different sources on the intertubes. It seems that to l...

I am bothered by the following code snippet in my program. If I write mo=[[myObj alloc] init]; it fails, but if I write mo=[myObj alloc]; mo=[mo init]; it works. These two methods are supposed to be equivalent but somehow I am messing up. Any light? Clarifications: myObj is the name of a class It fails by trying to allocate for...
I couldn't find a convenient way to create an alias, so I went with a symlink. I'm worried that that might not be good enough. Maybe the icon doesn't show on some versions of OS X or something like that. [[NSFileManager defaultManager] createSymbolicLinkAtPath:aliasPath withDestinationPath:destPath error:nil]; Is this sort of thing th...
I am not an idiot, but header files make me feel like one sometimes. I have what is probably an overly-complicated set-up that has an error that I cannot resolve. Here it is in about as simple as detail as I can make it.... I have a Controller class that contains a Model class. I have a Scene class to capture actions and communicates ...
Maybe my memory has gone completely wacko, but I think I remember that declaring pointers without initializing them made them point to nil. But recently this doesn't seem to be the case. Has it always been this way? Or has it something to do with the compiler settings? ...

I've been having a problem creating a checklist in the style of the TouchCells example from the Apple sample code. Basically, it is a table that allows multiple selection of its items and gives each selected item a check mark. The problem I'm having is that when I select an item and then scroll down the screen, another item (off the scr...
I'm new to iPhone development and Xcode, so this might be really obvious. I have the exact same problem as referenced on this forum post I've created a simple list application, starting out with a custom datasource class that simply returns a hard-wired list of data. With that working, I'm now attempting to alter my dataso...
I need to get it as a string to use elsewhere in the program, I'm not worried about compiler settings. I found HowToGetHardwareAndNetworkInfo on CocoaDev, but it seemed a little intense when all I wanted to know is PPC vs. Intel. ...
I want a list of unique contacts that I've stored with core data.

I'm adding a custom background image to my UINavigationBar by overriding the drawRect via a category. - ( void )drawRect:( CGRect )rect{ [[UIImage imageNamed:@"navbar.png"] drawInRect:CGRectMake( 0, self.frame.size.height-44, self.frame.size.width, 44 )]; } This solution seems to work fine, until you try to make use of navigatio...
I am working on an application that will perform a search against an online service and generate many Result objects. A Result object is an NSManagedObject, initialized as required by associating it with an NSManagedObjectContext. Users should be able to select a "Result" and save it as a "Favorite". In the application this is as simple...
I store names as keys and scores as values into an NSDictionary for saving in NSUserDefaults. I then want to get back the keys sorted by score, but I can't seem to sort them numerically, only by string. The result of 100, 50, 300, 200, 500 for example would be 100, 200, 300, 50, 500 Can this be done or do I need to go about this diffe...
I'm still not sure I totally get how this particular case should work out. So if I want to declare an array of NSStrings that won't change, is this correct? static NSString * const strings[] = {@"String 1", @"String 2", ...}; Is the static necessary? (what does it do?) Am I missing an extra const somewhere? There's just too many pl...
