use prepareForSegue for button - objective-c

Question

Hi I create button programmatically and I connect my button to another view, but I got segue problem
that I should use prepareForSegue method for storyboard but I don't know how there ar esome sample to the internet but I will get error when I used that sample, would you please help me
Thanks in advance!
here is my code
Creating Button
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
button.backgroundColor=[UIColor colorWithRed: 201.0/255.0 green: 201.0/255.0 blue:201.0/255.0 alpha: 1.0];
button.tag = currentTag;
currentTag++;
[button.layer setBorderColor: [[UIColor blackColor] CGColor]];
[button.layer setBorderWidth: 1.0];
[button setTitle:[NSString stringWithFormat:#"%d",currentTag] forState:UIControlStateNormal];
button.frame = CGRectMake(80*x, 32*y, 80, 32);
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[buttonView addSubview: button];
Action for button
-(void)buttonPressed:(UIButton *)button
{
NSLog(#"button %u -- frame: %#", button.tag, NSStringFromCGRect(button.frame));
WeekView *crtObj=[[WeekView alloc]initWithNibName:#"WeekView" bundle:nil];
[self.navigationController pushViewController:crtObj animated:YES];
[crtObj release];
}
Prepare for segue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"WeekView"]) {
// Get reference to the destination view controller
WeekView *vc = [segue destinationViewController];
// Pass any objects to the view controller here, like...
[vc setMyObjectHere:object]; //// I don't know what should I write instead of object
}}
error
Edit 2:**** I have a warning :
Segues initiated directly from view controllers must have an identifier for use with -[UIViewController performSegueWithIdentifier:sender:]
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"WeekView"]) {
// Get reference to the destination view controller
// WeekView *vc = [segue destinationViewController];
// Pass any objects to the view controller here, like...
// [vc setMyObjectHere:object];
[segue.destinationViewController setTitle:#"WeekView"];
}}

Answer 1

There are really two ways to push a view controller onto the navigation controller.
The old way, all in code. That is what you did. You can completely forget about segues at this point.
The new way: establish a Segue in Storyboard (push segue from one view controller to a new view controller, which you also define in Storyboard), give it an Identifier name and then use this code to push the view controller.
.
[self performSegueWithIdentifier:myIdentifyer sender:self];
where self is the view controller. Now you can do the customizations in prepareForSegue:.

Answer 2

the sample code in this case is just telling you the type of thing you can do in prepareForSegue:sender: .
it is suggesting that the viewController to which you are attempting to segue would have a method setMyObjectHere: and it would be expecting you to pass that object.
as an example, your class might have a setTitle: method, and in the prepareForSegue:sender: code, you could pre-set the title based on information in the controller you are performing the segue from.
to get rid of the warning, you need an identifier, as in the picture below:

Answer 3

"The old way to code", no the better way to code hopefully this helps, but if your using UIButtons and UIViews programmatically you shouldn't even be using segues.
Create a root view control in app delegate, than just pop on and off the next viewcontrollers and such.
For example this is all you need in your viewcontrollers:
-(void)nextControllerButton:(UIButton*)button{
SearchViewController *nextController = [[SearchViewController alloc] init];
nextController.username = _username.text;
nextController.password = _password.text;
[self.navigationController showViewController:nextController sender:self];
}
