prepareForSegue（ViewController）

Question

然后我嘗試將數據從一個視圖發送到另一個視圖

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]

    }

}

我在女巫遇到錯誤時說ViewController是未聲明的？

Answer 1

您可以直接從情節viewController調用viewController並傳遞數據，而不是prepareForSegue

在要傳遞數據的文件中聲明變量，並#import要在其中傳遞數據的頭文件。

#import "file.h"

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

然后按照以下步驟導航...

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

[navigationController pushViewController:createEvent animated:YES];
