Switching Views Source Code

ybrikeeg · 07-30-2009, 12:25 AM

Hi there,
I'm have some trouble with the tutorial on how to switch views from iphonedevcentral.org. I have tried every thing, and I can't get it to work.

I was wondering if someone could post the source code. You can email it to me at ybrikeeg@yahoo.com

Thanks

Thanks for the reply MaXiMuM,
But what I'm looking for is how to have two different buttons take you to two different screens. I can't get that to work from a tutorial on how make one button take you to another screen. Any other help would be grealy appreciated.

Thanks for you help, but I've already look at that tutorial. how would you get two buttons on the homescreen to take you to two different views? It must be different from the youtube tutorial because repeating the process doesn't work.

I am currently working on an app that utilizes this. In my mainViewController.h I have these 3 IBActions:

Code:

- (IBAction)loadSecondView:(id)sender;
- (IBAction)loadThirdView:(id)sender;
- (IBAction)loadFourthView:(id)sender;

So in my mainViewController.m is like so:

Code:

#import "mainViewController.h"
#import "SecondViewController.h"
#import "ThirdViewController.h"
#import "FourthViewController.h"

@implementation mainViewController

- (IBAction)loadSecondView:(id)sender {

     SecondViewController *Second = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
     [self presentModalViewController: Second animated: YES];

}

- (IBAction)loadThirdView:(id)sender {

     ThirdViewController *Third = [[ThirdViewController alloc] initWithNibName:nil bundle:nil];
     [self presentModalViewController: Third animated: YES];

}

....// Same concept for Fourth view

Then you should be able to go into Interface Builder and create your mainViewController.xib with 3 buttons and connect each button to the correct function. And if you wanted to go back to the main menu you would use a function that calls [self dismissModalViewController: .... animated: YES] in each of your sub view controllers and link a button to the function that makes the call.

Using this method doesn't it auto instantiate All your subviews automatically when the root view is created? The app I'm working on myself has 8 views and a few views have custom picker controls, seems like this would be bad for memory..

I'm trying to figure out how to do creation dynamically with a rootViewController myself, but I'm kinda stuck on how exactly to switch. I've seen some suggestions to use the notification API and have the root controller listen for it. With this I'm stuck with I won't know which view is calling the display for the new view so I can release it and load the new one.

anyone have any additional suggesstions on this subject?
