how can I call a screen with a button action (xcode) ?

Question

I am developing a Window Based app for iPhone. I use Interface Builder to build Interface. I want to call a new screen with a Button Action. How can I call the screen with Button action ?

Answer 1

By pushing the new controller onto the top of the stack of windows. For example:

EnterNameController *newEnterNameController = [[EnterNameController alloc] initWithNibName:@"EnterName" bundle:[NSBundle mainBundle]];
[[self navigationController] pushViewController:newEnterNameController animated:YES];

Answer 2

Apple has an extraordinary amount of sample code, and this question (as well as many others) could easily be solved by simply visiting Apple's iPhone dev site. iPhone Dev Site

If you are using a navigation controller, push it onto the navigation controller's stack, as alamodey suggested.

If you want it to be a modal controller (that is, slide up from the bottom and cover the previous controller's view, like the Bookmarks screen in Safari), present it as a modal view controller:

[self presentModalViewController:myNewController animated:YES];

When you want to bring the old controller back, dismiss the modal view controller. From inside the modal view controller:

[self.parentViewController dismissModalViewControllerAnimated:YES];

If you don't want to do either, just remove the current controller's view from the window and add the new controller's:

UIView * containingView = self.view.superview;
[self.view removeFromSuperview];
[containingView addSubview:myNewController.view];

If you go this route, you may want to look into +[UIView beginAnimations:context:], +[UIView setAnimationTransition:onView:], and +[UIView commitAnimations] (if I recall the method names correctly--check the documentation) to animate the transition. You should almost always animate any switch between screens in iPhone OS.

i have developed tabbar based appliction.as well as particular tabitem is pressed then view is open ok.in this view i add three button with the help of coding(means without using tools),then button is coming.i wrote this code inside DidViewLoad method.this is the code for button:

 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
 [button setTitle:@"Create Tags" forState:UIControlStateNormal];
 button.frame = CGRectMake(100.0, 100.0, 100.0, 34.0);
 [self.view addSubview:button];
 [button addTarget:self action:@selector(createAction) forControlEvents:UIControlEventTouchUpInside];

but my problem is when i clicked on particular button then method is called but next view is not opened.this the code:

-(IBAction)createAction:(id)sender {WhoIsInAppDelegate *newEnterNameController = [[WhoIsInAppDelegate alloc] initWithNibName:@"Create Tags" bundle:[NSBundle mainBundle]]; [[self navigationController] pushViewController:newEnterNameController animated:YES];

} what is the wrong steps i doing please tell me.

Thanks in advanced.
