For now, inside the block, simply log the 'succeeded' parameter using NSLog. BOOL values are really just int values (0 or 1), so you can use the int format specifier: %d. Remember: format specifiers are placed in between the double quotes of an NSString literal, and then the values to be plugged in are specified after the NSString, separated by commas.

Here is a hint: this is what a NSLog with a format specifier usually looks like:

NSLog(@"%d", myVariable);

It tells you what specifier to use (%d), so you should be able to figure it out now

I think you have an extra quotation mark there my friend. the correct format ought to be:

NSLog(@"%d", myVariable);

NOT

NSLog(@"%d", myVariable");

as for myself, NSLog(@"%d", succeeded); is the code that worked.

This should work: NSLog(@"%d", succeeded);

I'm using this, but it doesn't appear to work, does anyone see why?

[newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) { NSLog(@"%d", succeeded) };

you need to close your square bracket of the method call

 [newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) 
   { NSLog(@"%d", succeeded) }];

It doesn't work for me. This one should be rather easy, like Gregg said but I'm afraid I'm missing something. I just can not get it right. If it is only "succeeded "we have to log than I have no clue besides NSLog(@"%d", succeeded); solution which is clearly not the solution.

The solution is in the block where this code is placed. It should be in the {} immediately after the ^(BOOL cr*p)...... :)
