Passing array to a segue

问题

I'm trying to pass an array from view A to segue B, here's the code:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([[segue identifier] isEqualToString:@"B"]) {
        BViewController *B = [segue destinationViewController];
        [B setBArray:self.AArray];
}

I've declared BArray as property in BViewCOntroller:

  @property (retain) NSMutableArray *BArray;

and synthesized it....

and the error is

NSInvalidArgumentException', reason: '-[UINavigationController setBArray:]: unrecognized selector sent to instance...

where am i wrong? Thank you in advance,

回答1:

The destinationViewController is returning a UINavigationController, not a BViewController. Are you segueing to a new UINavigationController? May be a mistake in your storyboard.
