Following a previous answer, I am implementing this piece of code to add a UIBarButtonItem to my viewController:
[self.navigationItem setHidesBackButton:YES];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRewind target:self action:selector(backButton:)];
backButton.tintColor = [UIColor redColor];
self.navigationItem.rightBarButtonItem = backButton;
The error warning is:
Expected )
at backButton declaration line.
I have searched the internet to find the valid format of the declaration, but I think it is correct as it is now, but the compiler shows the error warning.
Any help is welcome.
