I have found the solution to the problem. It seems that I have to
pass a mutable string with the path to the file handle's factory
method. Looking back at the output of the error, now it seems
pretty obvious. My worry now is that I am new to the macos
development environment, and I am programming while looking at the
documentation I have installed in my machine. I have tiger, but
upgraded to xcode 2.5 from the version supplied with OSX. The
documentation for the NSFileHandle class shows me in its signature
an NSString as its argument.
Is this common in apple API's or am I looking at the wrong
document's ?
You must show your code to get help.
I guess that you pass an autoreleased string to the file handle, and
the exceptions you get are raised when the file handle try to send a
message to the object you passed, which does not exists any more. The
same address is used now by another object, (an NSArray) which
complain about unrecognized selectors. This is a very common error
for Cocoa beginners.
You should read carefully the memory management guidelines: http://
developer.apple.com/documentation/Cocoa/Conceptual/MemoryMgmt/Tasks/
MemoryManagementRules.html
