objective c - Error for open connect of database with FMDB -

when i'm going open connect database, console says: "error opening!: 14". included "mybase.sqlite" on folder resources of project , i'm using fmdb framework.

for open connect i'm using code:

 nsautoreleasepool * pool = [[nsautoreleasepool alloc] init];         fmdatabase* db = [fmdatabase databasewithpath:@"/mybase.sqlite"];     if (![db open]) {         nslog(@"não abriu o banco de dados.");         [pool release];         return 0;     } 

in appdelegate, included code:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {          // override point customization after application launch.  homeviewcontroller *homevc = [[homeviewcontroller alloc] init];  navigationcontroller = [[uinavigationcontroller alloc] initwithrootviewcontroller:homevc];    [self createeditablecopyofdatabaseifneeded];  [window addsubview:navigationcontroller.view];     [window makekeyandvisible];      return yes; }  - (void)createeditablecopyofdatabaseifneeded{  bool success;  nsfilemanager *filemanager = [nsfilemanager defaultmanager];  nserror *error;  nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes);  nsstring *documentsdirectory = [paths objectatindex:0];  nsstring *writabledbpath = [documentsdirectory stringbyappendingpathcomponent:@"mybase.sqlite"];  success = [filemanager fileexistsatpath:writabledbpath];  nslog(@"success %d", success);  if (success) return;    nsstring *defaultdbpath = [[[nsbundle mainbundle] resourcepath] stringbyappendingpathcomponent:@"mybase.sqlite"];  success = [filemanager copyitematpath:defaultdbpath topath:writabledbpath error:&error];  if (!success) {   nsassert1(0, @"failed create writable database file message '%@'.", [error localizeddescription]);  }  } 

i think open path incorrect. specifying path doesn't make sense, if db file in root folder.

fmdatabase* db = [fmdatabase databasewithpath:@"/mybase.sqlite"]; 

the above should use code file path, have in question.

nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes); nsstring *documentsdirectory = [paths objectatindex:0];  nsstring *writabledbpath = [documentsdirectory stringbyappendingpathcomponent:@"mybase.sqlite"]; fmdatabase* db = [fmdatabase databasewithpath:writabledbpath];
