indexesThe indexes of the objects to remove from the array. The locations specified by
indexesmust lie within the bounds of the array.
Discussion
This method is similar to remove, but allows you to efficiently remove multiple objects with a single operation. indexes specifies the locations of objects to be removed given the state of the array when the method is invoked, as illustrated in the following example:
NSMutableArray *array = [NSMutableArray arrayWithObjects: @"one", @"a", @"two", @"b", @"three", @"four", nil];
NSMutableIndexSet *indexes = [NSMutableIndexSet indexSetWithIndex:1];
[indexes addIndex:3];
[array removeObjectsAtIndexes:indexes];
NSLog(@"array: %@", array);
// Output: array: (one, two, three, four)
If indexes is nil, this method raises an exception.
