加载笔尖但视图插座未设置 - Swift版 [英] Loaded nib but the view outlet was not set - Swift edition

问题描述

我有一个项目全部在Objective C中，除了我的视图控制器，它在Swift中。

I have a project that is all in Objective C, except for my view controller, which is in Swift.

当我运行它时，我收到错误

When I run it, i get the error

由于未捕获异常而终止应用程序
'NSInternalInconsistencyException'，原因：' - [UIViewController
_loadViewFromNibNamed：bundle：]加载了...笔尖，但未设置视图插座。'

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "..." nib but the view outlet was not set.'

所以我打开了我的nib文件，看看文件的所有者，我看到该视图甚至根本不显示为插座。

对于我的旧视图控制器（目标c），视图插座确实显示出来。

So I opened up my nib file, look at "File's Owner", and I see that the view does not even show up as an outlet at all.
For my old view controller (objective c), the view outlet does show up.

在我的Swift视图控制器中，我尝试从UIViewController覆盖view变量以强制它为@IBOutlet，但它抱怨view变量属于类型UIView，抱怨UIView？，抱怨UIView！。

In my Swift view controller, I tried overriding the "view" variable from UIViewController in order to force it to be an @IBOutlet, but it complained about the "view" variable being of type UIView, complained about UIView?, and complained about UIView!.

以下是

我的AppDelegate的简化版本.H

my AppDelegate.h

#import <UIKit/UIKit.h>

@class MyViewController;
@class MyViewControllerSwift;

@interface MSAppDelegate : UIResponder <UIApplicationDelegate>
{
}

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) UIViewController *viewController;

@end

AppDelegate.m

AppDelegate.m

#import "MyAppDelegate.h"

#import "MyViewController.h"
#import "MySwift-Swift.h"
#import <UIKit/UIKit.h>

@implementation MyAppDelegate

static BOOL USE_SWIFT_VIEW_CONTROLLER = YES;

- (void)dealloc
{
    [_window release];
    [_viewController release];
    [super dealloc];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.

    id viewControllerPtr = nil;
    if(USE_SWIFT_VIEW_CONTROLLER)
    {
        viewControllerPtr = [MyViewControllerSwift alloc];
    }
    else
    {
        viewControllerPtr = [MyViewController alloc];
    }

    UIViewController* vController = nil;
    if(USE_SWIFT_VIEW_CONTROLLER)
    {
        vController = [[viewControllerPtr initWithNibName:@"MyViewControllerSwift" bundle:nil] autorelease];
    }
    else
    {
        vController = [[viewControllerPtr initWithNibName:@"MyViewController" bundle:nil] autorelease];
    }

    self.viewController = vController;
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];

    return YES;
}

ViewController.swift

ViewController.swift

import Foundation
import AVFoundation

@objc class MyViewControllerSwift : UIKit.UIViewController {

    var player : AVFoundation.AVAudioPlayer?;

    @IBOutlet weak var myTextView : UITextView!;

    required init(coder aDecoder : NSCoder) {
        super.init(coder:aDecoder);
    }

    override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
        super.init(nibName:nibNameOrNil, bundle:nibBundleOrNil);
    }

    override func viewDidLoad() {
        super.viewDidLoad();

        println("Using MyViewControllerSwift");
    }

    deinit {
        //TODO
    }
}

我需要做什么才能显示我的视图？

What do I need to do to get my view to display?

谢谢。

（是的，这是与已加载的笔尖但视图插座未设置 - InterfaceBuilder的新功能但视图插座未显示。）

(Yes, this is a similar question to Loaded nib but the view outlet was not set - new to InterfaceBuilder but the view outlet does not show up. )

推荐答案

• 首先 - 在你的nib文件中设置自定义类
  （文件所有者 - >第三个图标 - >自定义类：YourViewController）


• 秒 - 文件所有者中的最后一个图标 - >将view属性链接（拖动）到界面视图



像这样初始化你的ViewController：

Init your ViewController like so:

YourViewController(nibName: "YourViewName", bundle: nil)

它会起作用。不要使用View进行任何操作。

It will work. Don't do any manipulations with View.
