【IOS】StoryBoard传值TableView点击Cell

问题:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender;

以上方法会先于

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

因此我们必须在跳转的时候找到点击了那一行cell
可以用以下方法:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    //判断哪条segue
    if ([segue.identifier isEqualToString:@"showPhotoList"]) {
        PhotoTableViewCell *cell = (PhotoTableViewCell *)[[sender superview]superview];
        PhotoListViewController *plvc = segue.destinationViewController;
        plvc.model = [_photoLibraryArray objectAtIndex:[_tableView indexPathForCell:cell].row];
    }
}
