ios - 准备ForSegue( View Controller )

Question

然后我尝试将数据从一个 View 发送到另一个 View

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if segue.identifier == "varView" {
        var viewController = segue.destinationViewController as ViewController

        var indexPath = self.tableView.indexPathForSelectedRow()

        viewController.varView = self.exams[indexPath.row]

    }

}

我收到一个错误，witch said that ViewController is a undeclared?

Answer 1

您可以直接从 Storyboard调用viewController并传递数据，而不是prepareForSegue

在要传递数据的文件中声明变量，以及#import要在其中传递数据的头文件。

#import "file.h"

file *data = [[file alloc]init];
data.index = add_index;

然后按如下方式导航...

UINavigationController *navigationController = (UINavigationController *)self.navigationController;
UIViewController *createEvent = [self.storyboard instantiateViewControllerWithIdentifier:@"yourViewControllerID"];

[navigationController pushViewController:createEvent animated:YES];
