objectEnumerator()
Returns an enumerator object that lets you access each value in the dictionary.
Declaration
func objectEnumerator() -> NSEnumeratorReturn Value
An enumerator object that lets you access each value in the dictionary.
Discussion
The following code fragment illustrates how you might use the method.
NSEnumerator *enumerator = [myDictionary objectEnumerator];
id value;
while ((value = [enumerator nextObject])) {
/* code that acts on the dictionary’s values */
}If you use this method with instances of mutable subclasses of NSDictionary, your code should not modify the entries during enumeration. If you intend to modify the entries, use the allValues method to create a “snapshot” of the dictionary’s values. Work from this snapshot to modify the values.
Special Considerations
It is more efficient to use the fast enumeration protocol (see NSFastEnumeration). Fast enumeration is available in macOS 10.5 and later and iOS 2.0 and later.
