iOS cocoa retain variable block

Question

I need to retain a variable inside a block because i have to pass it to a method out of the block. I dont know how to achieve this.

__weak MyClass *weakSelf = self;
[myFile addObserver:self block:^
{
       if ([[[weakSelf myFile] newerStatus] cached] )
       {

            [weakSelf performSelector:@selector(myMethod:) withObject:weakSelf.myFile afterDelay:5];
       }

}];

I tried also doing this but no success:

__block DBFile *myFileFinal;

 __weak MyClass *weakSelf = self;
[myFile addObserver:self block:^
{
       if ([[[weakSelf myFile] newerStatus] cached] )
       {
            __strong MyClass *strongSelf = weakSelf;
            myFileFinal = strongSelf.myFile;
            [weakSelf performSelector:@selector(myMethod:) withObject:myFileFinal afterDelay:5];
       }

}];

How can i retain "myFile" for use outside of the block? Need help please. Thanks in advance.

I don't know what you mean by "How can i retain "myFile" for use outside of the block?"

performSelector:withObject:afterDelay: retains the receiver and arguments until the action is performed.
