当我使用storyboard id时如何将数据传递到目标视图？

Question

基本上，当我想将数据从源视图传递到目标视图时，我使用＆＃34; prepareForSegue＆＃34;方法并使destinationView等于segue的destinationView。

但是如果我想在下面的代码中使用Storyboard ID来呈现我当前视图的上方：

MyCustomViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"MyViewController"];
[self presentViewController:vc animated:YES completion:nil];

如何使用Storyboard ID ??

将数据从当前视图传递到目标视图

Answer 1

同样的方式..

MyCustomViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"MyViewController"];
vc.someProperty = something;  //use your data here
[self presentViewController:vc animated:YES completion:nil];

Answer 2

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Make sure your segue name in storyboard is the same as this line
    if ([[segue identifier] isEqualToString:@"SEGUE_NAME_HERE"])
    {
        // Get reference to the destination view controller
        ViewController *objVc = [segue destinationViewController];
        objVc.objectProperty = object;

    }
}

Answer 3

我经常快速完成，这不是最佳做法，但我使用NSUserDefaults远程保存数据，而不创建CoustomViewController。
