Hi,
When looking how to implement an NSOperationQueue with a loop, I found several
examples that have the following structure:
NSInteger i;
for ( i = 0; i < 1000; i++ ) {
[queue addOperationWithBlock:^{
i += 1;
}];
}
But I get a compiler error: Variable is not assignable (missing __block type
specifier)
I solved by declaring the declaration for i:
NSInteger __block i;
But why does it work in the examples I found?
Thanks,
- Koen.
