我有一个需要由我的 iOS 应用程序读取的 sqlite 文件，但是 xcode 在将它复制到应用程序中时给了我一个错误...我将 sql 文件放在我项目的“支持文件”文件夹中。这是代码：

-(NSString *)filePath {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                         NSUserDomainMask,
                                                         YES);

    return [[paths objectAtIndex:0] stringByAppendingPathComponent:
                                                         @"LocationsApp.sql"];
}

-(void)createEditableCopyOfDatabaseIfNeeded {
    BOOL success;
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error;
    NSString *writableDBPath = [self filePath];
    success = [fileManager fileExistsAtPath:writableDBPath];

    if (success)
    {
        return;
    }

    NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"LocationsApp.sql"];
    success = [fileManager copyItemAtPath:defaultDBPath toPath:writableDBPath error:&error];
    if (!success)
    {
        NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);
    }
}

这是错误：

更正您的 DBName

LocationsApp.sql to LocationsApp.sqlite

或者你的 DBName 是什么
