I'd
start with the "Short Practical Guide to Blocks" -
http://developer.apple.com/library/ios/#featuredarticles/
Short_Practical_Guide_Blocks/_index.html.
OK, will do that.
if I try to pass on someString in a C struct (contextInfo) then the
compiler complains that ARC doesn't like object pointers in C
structs.
I could serialize and unserialize the string. Or is there a better
way?
Just use the NSString * right in the block - no need for structs,
serialization, or anything. That's why blocks are so useful.
I still need an alternative because I want to support Leopard where
blocks aren't available. I've written some code using
NSPropertyListSerialization which should do the trick.
