Dismissing Modal View Swift
提问by rocket101
EDIT: Thanks to the person behind the answer below, who fixed the unknown class. However, can anyone tell me if the code to dismiss is correct? I am on vacation and can't program until I get back.
编辑：感谢下面答案背后的人，他修复了未知类。但是，谁能告诉我解雇的代码是否正确？我正在休假，在我回来之前无法编程。
I am developing an app in Swift. Currently, I am working on an info screen (legal notices, credits, documentation, etc) that will be presented modally atop the main screen.
我正在 Swift 中开发一个应用程序。目前，我正在处理一个信息屏幕（法律通知、信用、文档等），它将在主屏幕上以模态呈现。
The expected behavior is that, when a button press triggers Dismissin InfoViewController, the modal view controller is dismissed.
预期的行为是，当在 中触发按钮按下Dismiss时InfoViewController，模态视图控制器将被解除。
Here's the code I'm trying to use:
这是我尝试使用的代码：
//This is InfoViewController, the swift file used to conorol the info screen.
import UIKit
class InfoViewController: UIViewController {
@IBAction func Dismiss(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: {});//This is intended to dismiss the Info sceen.
println("pressed")
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
}
Here's the layout of the storyboards:
这是故事板的布局：
When I press the button, the app crashes and doesn't dismiss the modal view controller.
当我按下按钮时，应用程序崩溃并且不会关闭模态视图控制器。
It compiles, suggesting it is not a syntactual error.
它编译，表明它不是语法错误。

The main issue here is Unknown class InfoViewController in Interface Builder file.
这里的主要问题是 Unknown class InfoViewController in Interface Builder file.
You need to make sure that (in 'Custom Class' section)
您需要确保（在“自定义类”部分）
1) The class in the storyboard is set to InfoViewController
1）storyboard中的class设置为 InfoViewController
2) The module is set to 'Current - your project name'
2）模块设置为“当前 - 您的项目名称”
