In my Cocoa application, in the header file, I declare a NSString ivar:

NSString *gSdkPath;

Then, in awakeFromNib, I assign it to a value:

gSdkPath = @"hello";

Later, it's value is changed in the code:

gSdkPath = [NSString stringWithString:[folderNames objectAtIndex:0]];

(the object returned from objectAtIndex is an NSString)

However, after this point, in another method when I try to NSLog() (or do anything with) the gSdkPath variable, the app crashes. I'm sure this has something to do with memory management, but I'm beginning with Cocoa and not sure exactly how this all works.

Thanks for any help in advance.
