架构x86_64-领域

问题描述

我正在开发Objective-C应用程序并将Realm用于数据存储。我已经在文件WordsList.h中创建了一个从RLMObject继承的类。

#import <Realm/Realm.h>
#import "Word.h"

RLM_ARRAY_TYPE(Word)

@interface WordsList : RLMObject

@property NSString *name;
@property NSString *basicLanguage;
@property NSString *learnedLanguage;
@property RLMArray<Word *><Word> *words;

@end


@implementation WordsList
+ (NSArray *)requiredProperties {
    return @[@"name",@"basicLanguage",@"learnedLanguage",@"words"];
}
@end

我需要在两个控制器中分别在TableViewController和VocabularyViewController中创建此类的对象，因此我在"import WordsList.h"文件（.h中TableViewController.h VocabularyViewController.h）。我在下面介绍它们：

#import "VocabularyViewController.h"
#import "LanguagesViewController.h"
#import "ListNameCell.h"
#import "WordsList.h"

@interface TableViewController : UITableViewController <UISearchBarDelegate,LanguagesViewControllerDelegate,UIGestureRecognizerDelegate>

@property (weak,nonatomic) IBOutlet UISearchBar *searchBar;
@property (nonatomic,retain) RLMResults<WordsList *>  *wordsLists;
@property (atomic,retain) RLMRealm *realm;

@end

#import <UIKit/UIKit.h>
#import <Realm/Realm.h>
#import "WordCell.h"
#import "WordsList.h"

@interface VocabularyViewController : UIViewController <UITableViewDataSource,UITableViewDelegate>

@property (nonatomic,weak) NSString *vocabularyListName;
@property (weak,nonatomic) IBOutlet UIButton *startButton;
@property (weak,nonatomic) IBOutlet UIButton *addNewButton;
@property (weak,nonatomic) IBOutlet UITableView *tableView;
@property (weak,nonatomic) WordsList* parentList;


@end

如果我在"import "WordsList.h"中键入VocabularyViewController.h，则会出现编译错误：架构x86_64的10个重复符号。确切的错误如下所示：

duplicate symbol '_OBJC_IVAR_$_Word._learnedLanguageText' in:
    /Users/art/Library/Developer/Xcode/DerivedData/Wordee-fafzcjxmbshrdqcvppmrdbdlvzze/Build/Intermediates.noindex/Wordee.build/Debug-iphonesimulator/Wordee.build/Objects-normal/x86_64/VocabularyViewController.o

我已经尝试了许多在本网站和互联网上找到的解决方案， 重新安装该库，删除Obj-C标志，将“ NO COMMON BLOCKS”设置为NO，删除DerivedData，但没有效果：/有没有人遇到过类似的问题？这是Realm库错误吗？

解决方法

暂无找到可以解决该程序问题的有效方法，小编努力寻找整理中！

如果你已经找到好的解决方法，欢迎将解决方案带上本链接一起发送给小编。
