为 StoryBoard 使用修改 didSelectRowAtIndexPath，IOS

我认为问题出在我无法在情节提要项目中使用的 didSelectRowAtIndexPath 中。 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { PetsViewController *pets = [[PetsViewController alloc] initWithNibName:@"PetsViewController" bundle:nil];

if ([[petsArray objectAtIndex:indexPath.row] isEqual:@"Dog"]) {
    pets.petsInt = 0;
    [pets setTitle:[petsArray objectAtIndex:indexPath.row]];
}

if ([[petsArray objectAtIndex:indexPath.row] isEqual:@"Cat"]) {
    pets.petsInt = 1;
    [pets setTitle:[petsArray objectAtIndex:indexPath.row]];
}

if ([[petsArray objectAtIndex:indexPath.row] isEqual:@"Snake"]) {
    pets.petsInt = 2;
    [pets setTitle:[petsArray objectAtIndex:indexPath.row]];
}

[self.navigationController pushViewController:pets animated:YES];

}

    @end

Answer 1

[self performSegueWithIdentifier:@"SEGUE_NAME" sender:self];


- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([[segue identifier] isEqualToString:@"SEGUE_NAME"]) {
        PetsViewController *pets = [segue destinationViewController];

        [pets setPetsInt:0];
        [pets setTitle:@"Title"];
    }
}

Answer 2

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
NSIndexPath *indexPath = self.tableView.indexPathForSelectedRow;

if ([[gazel objectAtIndex:indexPath.row] isEqual:@"<էրեբունի> Օդանավակայան"]) {
    KangarList *kang = [segue destinationViewController];
    kang.kangarInt = 0;
    [kang setTitle:[gazel objectAtIndex:indexPath.row]];
}

if ([[gazel objectAtIndex:indexPath.row] isEqual:@"<էրեբունի> Օդանավակայան"]) {
    KangarList *kang = [segue destinationViewController];
    kang.kangarInt = 1;
    [kang setTitle:[gazel objectAtIndex:indexPath.row]];
}

if ([[gazel objectAtIndex:indexPath.row] isEqual:@"<էրեբունի> Օդանավակայան"]) {
    KangarList *kang = [segue destinationViewController];
    kang.kangarInt = 2;
    [kang setTitle:[gazel objectAtIndex:indexPath.row]];
}

if ([[gazel objectAtIndex:indexPath.row] isEqual:@"<էրեբունի> Օդանավակայան"]) {
    KangarList *kang = [segue destinationViewController];
    kang.kangarInt = 3;
    [kang setTitle:[gazel objectAtIndex:indexPath.row]];
}
}

我尝试了很多方法，最终实现了正确的方法，但它只有在视图下加载方法对象只有一个描述但如果它有类似 thise 的情况下才有效

gazel = [[NSMutableArray alloc] init];

Data *data = [[Data alloc] init];
data.title = @"<էրեբունի> Օդանավակայան";
data.subtitle = @"Հարաֆ Արևմտյան Թաղամաս";
data.photo = 1;
[gazel addObject:data];

它不工作
