Question

The app should forward to another view controller based on some data in a database. The database is working fine, but I can’t get the app to forward to the second view controller.
Here’s the code I have in place.

ssSecondViewController *tempView =[[ssSecondViewController alloc] init];
[self.navigationController pushViewController:tempView animated:YES];

I’m not getting any errors but when I run the code the screen forwards to a blank black view?

if you have already your viewController on storyboard then you can assign it by like below code & you must have set identifier to viewControler on storyboard

ssSecondViewController *tempView =[self.storyboard instantiateViewControllerWithIdentifier:@"yourIdentifier"];

set your viewController id here,in below image identifier is “MenuViewController”

if it is on .Xib file then

ssSecondViewController *tempView =[[ssSecondViewController alloc] initWithNibName:@"yourIdentifier" bundle:nil];

if you just want to add new viewController with programmetically without using already available viewController ,then you have to init it with initWithFrame then it shows viewController

ssSecondViewController *tempView =[[ssSecondViewController alloc] initWithFrame:CGRectMake(0,0,320,480)];

ssSecondViewController *tempView =[[ssSecondViewController alloc] init]; this line just allocates the viewController, it not have any location to draw it.
