从UITableView到DetailView的条件搜索基于对象状态

Question

我已经在我的下钻表中设置了Xcode故事板，以分支到两个详细视图。

我希望它根据我在表格视图中点击的Budget对象的状态来切换到任何一个。如果预算对象尚未初始化，我想要转到初始化视图。如果已经初始化，我希望它能够转向细节视图。

到目前为止，这就是我所拥有的......

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

    /*
     When a row is selected, the segue creates the detail view controller as the destination.
     Set the detail view controller's detail item to the item associated with the selected row.
     */

    if ([[segue identifier] isEqualToString:@"showDetailsOfBudget"]) 
    {

        NSIndexPath *indexPath = [self.budgetsTable indexPathForSelectedRow];
        BudgetDetailsViewController *detailsViewController = [segue destinationViewController];
        detailsViewController.budget = [self.budgetPlan.budgets objectAtIndex:indexPath.row];
    }
}

当然，这只会使它偏离细节视图。我希望它在案例为budget.initialized = false时使用“initializeBudget”segue如何实现 performSegue:withIdentifier:方法来执行此操作？

Answer 1

您需要根据您的情况启动方法performSegueWithIdentifier。

类似的东西：

if ([self.budgetPlan.budgets count] > 0) {
    [self performSegueWithIdentifier@"showDetailsOfBudget"];
} else {
    [self performSegueWithIdentifier@"createBudget"];
}
