ios - UIWebView 不再工作

Question

我重新编辑了我的问题，我在我的应用程序中设置了我的 WebView 大约两周时间，一切都很顺利。昨天我只想看看 webView 是否仍在工作，即使我没有更改任何类的代码，并且发出 SIGABRT。我从昨天开始就遇到了这个错误，不明白为什么它仍然给我一个 SIGABRT。我按照建议做了一些更改，但仍然没有任何效果。如果在 objective c 方面具有高级技能的人可以帮助我，我快要疯了，这是日志消息(如果需要，我可以显示我的所有代码，请随时编辑答案，以便我可以按顺序评价好的答案帮助我之后的人):

    here is my code :

  - (void)showWebView;
    {
        //here i call my webview in my RootViewController
        ViewController *WebViewVC = [[ViewController alloc] init];
        [[self navigationController] pushViewController:WebViewVC  animated:YES];
        [WebViewVC pushIt];

    }

//here is my WebViewController.h
        #import <UIKit/UIKit.h>
        #import <Foundation/Foundation.h>

    @interface ViewController : UIViewController <UIWebViewDelegate>
    {
         IBOutlet UIWebView *myWebView;
    }

    @property (nonatomic, retain) IBOutlet UIWebView *myWebView;
    -(void)XButton;
    -(void)pushIt;
    @end


    //here is my WebViewController.m
        -(void)pushIt;
    {

        navigation control
        self.navigationItem.hidesBackButton = YES;
        self.navigationItem.leftBarButtonItem = nil;


        self.title = @"*****";
        myWebView = [[UIWebView alloc] initWithFrame:self.view.frame];
        [self.view addSubview:myWebView];
        [self XButton];
        [self WebViewBrowserBackButton];

        NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
        NSString *defaults = [prefs stringForKey:@"myKey"];
        NSString *defaults2 = [prefs stringForKey:@"mySecondKey"];
        NSString *username = defaults; 
        NSString *password = defaults2;
        NSURL* url = [NSURL URLWithString:@"**************"]; 
        NSString* body = [NSString stringWithFormat:@"************",      username,     password];  
        NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url     cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30];
        request.HTTPMethod = @"POST";
        request.HTTPBody = [body dataUsingEncoding:NSStringEncodingConversionAllowLossy];

        [myWebView loadRequest:request];
    }

将 WebViewController 的 View 属性从 nib 文件连接到文件所有者的 View 对象。

异常跟踪清楚地表明您在 nib 中的 View 未连接。
