Cast NSNumber to int

H, I want to cast a NSNumber to int. When I execute the below code, my result should be 1, not 68213232. What am I doing wrong? Code: NSNumber *setCurrentCount = [NSNumber numberWithInt: 1]; NSLog(@"Test NSNumber cast to int: %i", setCurrentCount); Output: Test NSNumber cast to int: 68213232

Re: Global Object

Thanks, I found this (http://codeendeavor.com/archives/535) nice wrapper for ASL and I wanted to see how I could incorporate it in to my app. Since this is a foundation tool I wanted to init it in my "myTestApp.m" main function, and be able to call "[log info:@"Log Stuff"];" in any of my classes

Re: Apache Module

Ok, I know your idea of a CGI Proxy like PHP CGI and I might try and see how that works. If it works great, I may use it instead of a module, but for now I finish making my first cocoa module at http://mrgeckosmedia.com/mod_example.zip Thanks for the help, Mr. Gecko On Nov 28, 2009, at 9:32 AM,

Confused about Memory Management with Collections

Hi All, I am trying to find out how memory is retained/released when using different Cocoa collection classes. Is there a good resource on this anyone can connect me to? Here is some detailed questions about what I am trying to find out: If I create a dictionary in the following manner (where

Re: Confused about Memory Management with Collections

Hi Mazen, Yes, objects that are added to collections objects (array, set, dictionary) are automatically retained by that collection and not released until removed from the collection or the collection is deallocated. If you don't need them "anywhere else outside the dictionary", then you shoul

When to use exception handling?

I'm trying to understand when to use exception handling when developing Cocoa applications. In regard to this, two points stand out to me in Apple's documentation: "exceptions are resource-intensive in Objective-C" "Conditions giving rise to exceptions are due to programming errors; you shoul

Is there a key path for this?

I want to know if I can do this with bindings or not. I've read a good deal, and tried a few things without success. My document class has an array of Instructors, with a controller. Each instructor has a timeConstraint, which in turn has an array of NSNumbers. I have an NSTableView boun
