Hi,
The method that returns the NSTextAlignment is interpreting other data to come
up with the best alignment, if there is no “Best Alignment” it needs to signal
this back to the caller.
I’ve solved the problem by returning a BOOL to say if the NSTextAlignment is
valid or not and passing the actual NSTextAlignment value as &myTextAlignment,
e.g.
if ([self getBestAlignmentWithParam1:p1 andParam2:p2 andParam3:p3
returnTextAlignment: &myTextAlignment] == NO)
{
// do something else
}
Cheers
Dave
