objectEnumerator()
Returns an enumerator object that lets you access each object in the array.
Declaration
func objectEnumerator() -> NSEnumeratorReturn Value
An enumerator object that lets you access each object in the array, in order, from the element at the lowest index upwards.
Discussion
Returns an enumerator object that lets you access each object in the array, in order, starting with the element at index 0, as in:
NSEnumerator *enumerator = [myArray objectEnumerator];
id anObject;
while (anObject = [enumerator nextObject]) {
/* code to act on each element as it is returned */
}Special Considerations
When you use this method with mutable subclasses of NSArray, you must not modify the array during enumeration.
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.
