No. As two people have said already, *you can't initialize an object
more than once*. The only time an init method is to be called is
right after -alloc, when the object is first created. Calling it
again will unexpectedly reset part of the object's state, and
probably mess it up.
What you should do instead of the above line is
[SimParamnames release]; // to get rid of the old object
SimParamnames = [[NSDictionary alloc] initWithContentsOfFile:
aFile]; // new object
If for some reason you absolutely want/need to use the
NSMutableDictionary that you originally allocated, you can do
something like this:
[SimParamnames removeAllObjects];
[SimParamnames addEntriesFromDictionary:[NSDictionary
dictionaryWithContentsOfFile:aFile]];
That should work as expected without releasing the original mutable
dictionary (assuming you really do need it for something you cut in
the example).
