Ios 带有UITableview线程1的书签菜单：信号SIGABRT错误

我有以下问题。我创建了一个功能齐全的浏览器，但当我使用“添加书签功能”或“显示书签功能”时，总是会出现Thread1:signal SIGABRT错误。我试了8个小时后的一切，但我找不到解决办法。有人可以看看我的代码给我一个线索如何解决这个问题吗？我很沮丧，希望有人能帮助我，因为我真的不知道该怎么办。我认为这与“forKey”标签有关，但我不确定。这是我的密码：

AppDelegate.h：

#import <UIKit/UIKit.h>
@class ViewController;

@interface AppDelegate : NSObject <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;


@end

ViewController.h：

#import <UIKit/UIKit.h>
#import "FavoritenController.h"

@interface ViewController : UIViewController <UITextFieldDelegate,   UIWebViewDelegate, UIActionSheetDelegate>

{


UIWebView *Webseite;
UIBarButtonItem *backButton;
UIBarButtonItem *forwardButton;
UITextField *textField;
UIBarButtonItem *refreshButton;
NSString* urlBeforeEditing;


FavoritenController* favoritenController;

}

当您得到错误时，堆栈跟踪是什么样子的？我在问题中添加了它。不，这是崩溃时代码的汇编语言表示。堆栈跟踪将显示到达那里的调用序列。如果在调试控制台中键入“bt all”，它将打印堆栈符号。好的，抱歉。这个？
