将数组传递给segue [英] Passing array to a segue

问题描述

我正在尝试将数组从视图A传递到segue B，这是代码:

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];
}

我已经在BViewCOntroller中将BArray声明为属性:

I've declared BArray as property in BViewCOntroller:

  @property (retain) NSMutableArray *BArray;

并合成它....

错误是

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

我在哪里错?预先谢谢您，

where am i wrong? Thank you in advance,

推荐答案

destinationViewController返回的是UINavigationController，而不是BViewController.您是否正在寻找新的UINavigationController?可能是故事板上的一个错误.

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