ARC forbids Objective-C objects in structs or unions despite marking the file -fno-objc-arc? Why is this so?
I had the assumption that if you mark it -fno-objc-arc you don't have this restriction.
If you got this message try __unsafe_unretained. It is only safe, if the objects in the struct are unretained. Example: If you use OpenFeint with ARC the Class OFBragDelegateStrings says this error in a struct.
typedef struct OFBragDelegateStrings
{
NSString* prepopulatedText;
NSString* originalMessage;
} OFBragDelegateStrings;
to
typedef struct OFBragDelegateStrings
{
__unsafe_unretained NSString* prepopulatedText;
__unsafe_unretained NSString* originalMessage;
} OFBragDelegateStrings;
