Error while creating db in objective-c

Question

I am creating an app in IOS with cordova 2.1.0 framework. I am creating sqlite3 db in objective-c with following code:

NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
self.databaseFile = [docDir stringByAppendingPathComponent:@"splistdb.sqlite3"];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;


if (![fileManager fileExistsAtPath:self.databaseFile]) {
    /*[fileManager copyItemAtPath:[[NSBundle mainBundle] pathForResource:@"FriendsDatabase" ofType:@"sqlite3"] toPath:dbFileName error:&error];*/
    NSString *path = [[NSBundle mainBundle] pathForResource:@"splistdb" ofType:@"sqlite3"];
    NSLog(@"doc path=%@",path);
    [fileManager copyItemAtPath:path toPath:self.databaseFile error:&error];
    [self createConfigTable];
    NSLog(@"database created");
} else {
    NSLog(@"fail to create database");
}

I have included libsqlite3.dylib file in build phases heading. But i am getting following error:

 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSFileManager copyItemAtPath:toPath:error:]: source path is nil'

What could be wrong in my code? Thanks.

Answer 1

Your error message says that path is nil , probably because the file splistdb.sqlite3 is not being copied into the application bundle. Make sure that it is in your project, and has been added to your target application.

Answer 2

最有可能这行给你零价值

NSString *path = [[NSBundle mainBundle] pathForResource:@"splistdb" ofType:@"sqlite3"];
