Question

I am somewhat new to blocks and need some help. I want to store a block in an NSDictionary and execute said block when it is accessed based off its key. Here is what I have so far as an example.

NSDictionary *blocks = [NSDictionary dictionaryWithObjectsAndKeys:
                              ^{NSLog(@"Log Block 1");}, @"Block1",
                              ^{NSLog(@"Log Block 2");}, @"Block2",
                              nil];

I then enumerate through the dictionary by using keyEnumerator. I know the block is being stored properly because I call NSLog(@"%@", [blocks objectForKey:key]); during the enumeration and get <__NSGlobalBlock__: 0x100003750>. So I know I can access it but how can I execute it at this point?

Answer 1

Try this:

void(^myAwesomeBlock)() = [blocks objectForKey:key];
myAwesomeBlock();
