Hi
Please see the question in the comments of the following code.
NSMutableDictionary* aDictionary = (initialized with some objects)
for (id theKey in aDictionary) {
id anObject = [[aDictionary objectForKey:theKey] retain];
[aDictionary removeObjectForKey:theKey];
// Question: will this removal break or corrupt the loop of enumerating the
elements?
[anObject someMessage];
}
in java, Iterators allow the caller to remove elements from the underlying
collection during the iteration. is there similar semantics in objective-c?
