Passing a parameter to a block stored inside an array of blocks

Question

I have this declared on the interface

void (^ soc)(NSString *type, BOOL configured);

and

@property (nonatomic, assign) BOOL serviceOK;

Then inside a method on .m I have this:

soc = ^(NSString *type, BOOL configured){
    // ...
};

// other blocks defined here

And then this:

NSMutableArray *arrayBlocks = [[NSMutableArray alloc] initWithObjects:
                               [block1 copy],
                               [soc(typeOne, self.serviceOK) copy],
                               [block3 copy],
                               [block4 copy],
                               nil];

I have an error on the soc line with the message bad receiver type void (what ???)

If I simply run this:

soc(typeOne, self.serviceOK);

it works fine, but if I include it in the array it complains. Any help appreciated.

If you want to add a copy of the block then add:

[soc copy],

to the array. What you are trying to do is add a copy of the result of calling the block.

soc(typeOne, self.serviceOK)

executes the block. and as it is returning nothing, there is nothing to send the copy message to and put into the array.
