Passing blocks in Objective-C

Question

When writing a method that accepts a block as an argument, do I need to do anything special such as copying the block to the heap before executing it? For example, if I had

This all looks good. Though, you might want to double-check the block parameter:

@property id myObject;
@property (copy) void (^myBlock)(NSString *);

....

- (void)testWithBlock: (void (^)(NSString *))block
{
    NSString *testString = @"Test";
    if (block)
    {
        block(test);
        myObject = Block_copy(block);
        myBlock = block;
    }
}

...

[object testWithBlock: ^(NSString *test)
{
    NSLog(@"[%@]", test);
}];

Should be fine. And I believe that they are even trying to phase out Block_copy(), but they haven't yet.
