Question

I’m trying to create a header file as such:

#import <UIKit/UIKit.h>

typedef void (^RevealBlock)();

@interface BFTasksViewController : UITableViewController <UITableViewDataSource, UITableViewDelegate> {
@private
    RevealBlock _revealBlock;
}

- (id)initWithTitle:(NSString *)title withRevealBlock:(RevealBlock)revealBlock;

@end

But I get this warning:

Redefinition of typedef ‘RevealBlock’ is a C11 feature

Is this something to be worried about? I’m looking at the GHSidebarNav project, which seems to use it just fine.

Answer 1

You must have declared RevealBlock somewhere else, as i don’t see any import other than UIKit/UIKit.h, check you project .pch file for conflicting headers (or could it be that you removed some headers to make the snippet shorter ?).
