Answer 1

use below code for coping database when application launch

in your appdelegate.m

in

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

  [self getdatabase];

  return YES;
}

and add below function in to your appdelegate.m

-(void)getdatabase
{
    BOOL success;
    NSFileManager *filemanager = [NSFileManager defaultManager];
    NSError *error;
    NSArray *pathArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *DBPath = [pathArray objectAtIndex:0];
    NSString *writableDBPath = @"";
    writableDBPath = [DBPath stringByAppendingPathComponent:@"xyz.sqlite"];
    NSLog(@"writableDBPath:%@",writableDBPath);
    success = [filemanager fileExistsAtPath:writableDBPath];
    if (!success) {
        NSString *defaultDBpath = [[[NSBundle mainBundle]resourcePath]stringByAppendingPathComponent:@"xyz.sqlite"];
       success = [filemanager copyItemAtPath:defaultDBpath toPath:writableDBPath error:&error];
       if (!success) {
            NSAssert(0, @"failed to copy database at path with message '%@'.",[error localizedDescription]); 
        }
    }     
    NSLog(@"111writableDBPath:%@",writableDBPath);    
}
