iOS How can I easily connect 2 views?

JamesFoote said:

My app currently has a menu (that is not the mainview so it can't even be seen yet) and another 2 files (rootviewcontroller and mainview) that make up an RSS reding view. I want to be able to do 2 things:

1. Make the menu the mainview
2. Link one of the buttons on the mainview to the RSS view

anyone who can help me out with this rocks - a whole lot!!!

Hi can you be more clear!!

Anyways from what I have understood from the above quest, u want to make some view as the mainview and u wanna traverse from the mainview to the RSS View, if am not wrong..

for your first question : In order to make any view to be displayed first, it shld have a WINDOW in its class declaration and its NIB file shld be mentioned as the first NIB in the pInfo.list file if you are using the IB..

for ur second quest: Just create an Instance of that view controller which you wanna goto and then add its view as a subview to the mainview's window....

Hi ,

I use the below code ,But its not working.
Can you please tell me what is the error in the code?

#import "TestViewController.h"
#import "Test2ViewController.h"


@implementation TestViewController
@synthesize view2Controller;

-(IBAction)display🙁id)sender
{




//Load the view controller from the HelloView nib file.
Test2ViewController *vController = [[Test2ViewController alloc]
initWithNibName😡"Test2View" bundle:[NSBundle mainBundle]];

//set the view.
self.view2Controller = vController;

//release the view controller.
[vController release];


}


- (id)initWithNibName🙁NSString *)nibNameOrNil bundle🙁NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
// Initialization code
}
return self;
}





// If you need to do additional setup after loading the view, override viewDidLoad.
- (void)viewDidLoad {



Test2ViewController *view2 = [[Test2ViewController alloc] initWithNibName😡"Test2View" bundle:[NSBundle mainBundle]];
self.view2Controller = view2;
[view2 release];

}



- (BOOL)shouldAutorotateToInterfaceOrientation🙁UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}


- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview
// Release anything that's not essential, such as cached data
}


- (void)dealloc {
[super dealloc];
}
