Mounts is being used, but just not in the init function.
You have declared it as a local variable. It *cannot* be used
elsewhere.
I suspect that you have also declared it as a member (attribute,
property,
whatever) and expect that you're assigning to that, but the local
variable
will shadow that, and so there's your problem.
He may have that problem as well, but improper separation of alloc
from init as explained earlier was definitely causing the symptom
described. It's trivial to reproduce:
NSMutableArray *mounts;
NSMutableArray *bonjourServices;
mounts = [[NSMutableArray alloc] init];
[mounts initWithContentsOfFile:@"NonexistentFile"]; // causes
dealloc
bonjourServices = [[NSMutableArray alloc] init]; // reuses
dealloced memory
NSLog(@"mounts = [%X], bonjourServices = [%X], equal? %d",
mounts, bonjourServices, mounts == bonjourServices);
This gives me:
2008-11-17 10:10:53.285 Scratch2[21580:10b] mounts = [1317D0],
bonjourServices = [1317D0], equal? 1
