IOS - SQLite DB path from NSBundle mainbundle returns null

Question

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *databasePath = [documentsDirectory stringByAppendingPathComponent:@"idataBase.sqlite3"];
NSLog(@"%@",databasePath);
NSString *databasePathFromApp = [[NSBundle mainBundle] pathForResource:@"idataBase" ofType:@"sqlite3"];
NSLog(@"%@",databasePathFromApp);
bool databaseAlreadyExists = [[NSFileManager defaultManager] fileExistsAtPath:databasePath];
if (!databaseAlreadyExists){
    [[NSFileManager defaultManager] copyItemAtPath:databasePathFromApp toPath:databasePath error:nil];
}

I tried to copy the database to document directory, But it returns null when i try to get the database path from main bundle and my app crashed. The database is present in app. But why it returns null?

Answer 1

if you have twice .sqlite3 in your project

because may be your xCode target is "Build Phases" add the file under "Copy Bundle Resources"".
