That's cool, but it's actually possible to use recursive blocks directly if you simply declare the block as a __block variable. This works perfectly fine: __

That's cool, but it's actually possible to use recursive blocks directly if you simply declare the block as a __block variable. This works perfectly fine: __block void (^myBlock); myBlock = ^{ myBlock(); }; myBlock(); The only thing you have to watch out for is when the block gets copied prior to its invocation (e.g. if you pass it to some function that does a Block_copy on it). In that case you have to first copy the block yourself and update your block variable: __block void (^myBlock); myBlock = [^{ myBlock(); } copy]; someFunctionThatCopiesTheBlock(myBlock);
