Instance Method

indexesOfObjectsPassingTest:

Returns the indexes of objects in the array that pass a test in a given block.

Declaration

- (NSIndexSet *)indexesOfObjectsPassingTest:(BOOL (^)(ObjectType obj, NSUInteger idx, BOOL *stop))predicate;

Parameters

predicate

The block to apply to elements in the array.

The block takes three arguments:

obj

The element in the array.

idx

The index of the element in the array.

stop

A reference to a Boolean value. The block can set the value to YES to stop further enumeration of the array. If a block stops further enumeration, that block continues to run until it’s finished. The stop argument is an out-only argument. You should only ever set this Boolean to YES within the block.

The block returns a Boolean value that indicates whether obj passed the test.

Return Value

The indexes whose corresponding values in the array pass the test specified by predicate. If no objects in the array pass the test, returns an empty index set.
