I was wondering if I can put the NSMutableArray in Fruit.m file instead of putting it in the Delegate file? That way I would know what I have in Fruit object.

Thanks,

Here is my question:
I get the code part – the controllers, xibs etc.. and after the last few tutorials and other docs I can generalize the learnings into “rules” such as “if you have a variable, you need to create a @property in the .h file and a @synthesize in the .m file” etc….

What I am having a hard time grasping is this whole drag and connect in interface builder… Sometimes you drag from the view inspector to File’s owner, sometimes from the actual view to the View box in the Controller window… This drag-and-connect has me a bit confused and I am unable to generalize this in the form of rules I can learn (like above).

Can you provide some writeup about this? Or point me somewhere which has a lucid description of this? (there might be a tutorial further ahead in your site – if so I just havent gotten to it – if you can point me to that one that will also be great)

Thanks again!!

thanks again…

The code all the way below will switch a View Controller via a p-list by switching the name of the controller in the line of code… rvc.view = viewController.view;
and adding a new case #… case 1: {
RootViewController *rvc = [[RootViewController alloc]

so switching “rvc.view = viewController.view;” to “rvc.view = secondviewController.view;”
and adding a Case 2 enables you to switch between these two views depending on the users selection

if([Children count] == 0) {
NSInteger ViewNumber = [[dictionary objectForKey:@"View"] integerValue];
switch (ViewNumber) {
case 1: {
RootViewController *rvc = [[RootViewController alloc] initWithNibName:@”RootViewController” bundle:[NSBundle mainBundle]];
//Switch the view here
rvc.view = viewController.view;
[self.navigationController pushViewController:rvc animated:YES];
[rvc release];
}
break;

I’m running on the latest version of XCode (+ iPhone OS 3.1.3) and ran into some problems.
I took “description” and sort of cloned it to bring more data in.

Currently the app crashes when I select a cell, GDB says it’s got something to do with the ‘initWithName:bundle:’, since it can’t find a method like that.

That particular line is currently: FruitViewController *viewController = [[FruitViewController alloc] initWithName:@”FruitViewController” bundle:[NSBundle mainBundle]];

Has there been changes that are causing this? Feels like XCode doesn’t know what the “bundle” is, as that wasn’t mentioned in this article.

Thanks in advance!

Thanks for the great tutorial. As someone who hasn’t programmed in years and is just learning object oriented programming on iPhone, your tutorials are the most complete I’ve found. I’m currently about half way through the Apple Dev Intro vids. Great stuff there. Don’t sweat the comments about having to type the code in. Typing the code in does teach two important things. First, you don’t really know the syntax of a language until you have to type it in over and over again. Of course, the basic syntax comes quickly, but thankfully XCode goes a long way in helping avoid unnecessary typing. Second, the fact of the matter is that typing in the code WILL cause several syntax errors that you will get to find when you compile/run. While this may be a pain in the butt, it’s invaluable in your education learning out each part of the system works.

Thanks again. BTW, I’m glad I’m not the first one to notice you need to release each fruit object you make after you put them together into the array in FruitAppDelegate.m.

i got problem when i combine this project with my own project.

My project seems like this, i created an application with multiviews app. From one of the views, i have some buttons and one button that i want to connect to next view which is as example shown in this example. I copied all codes in FruitsViewAppDelegate into my project AppDelegate, being like this:

—-

- (void)applicationDidFinishLaunching:(UIApplication *)application{ {

// Override point for customization after application launch
[window makeKeyAndVisible];
FirstViewController *oView =[[FirstViewController alloc] initWithNibName:@”FirstViewController” bundle:nil];
self.firstView =oView;
[window addSubview: firstView.view];
// [window addSubview: nTraining.view];
[oView release];
}

{

Info *apple = [[Info alloc] initWithName:@”Course Benefit” description:@”The aim of this IPv6 training program is to give in depth information on the transition from IPv4 to IPv6 and expose the participants on the technical expertise needed in the deployment of IPv6 in the organizations network while CNP6 course concentrates in porting IPv4 based applications to IPv6 and writing IPv6 based applications.”];
Info *orange = [[Info alloc] initWithName:@”Who should attend?” description:@”CNE6 is ideal for network administrators, network support personnel, network designers, networking consultants, IT managers and directors. CNP6 is ideal for network programmers, network designers, networking consultants, IT managers and directors. “];
Info *watermelon = [[Info alloc] initWithName:@”Training Approach” description:@”Instructor – Led Training: Set in an interactive classroom environment, the instructor will introduce concepts and guide students with detailed explanations and interesting examples to meet the student’s expectation and requirements and at the same time keep the students engaged. Hands – On Lab: Step by step hand – on labs with detailed instructions and guide are provided to reinforce all key concepts. It allows the student to reinforce concepts by performing the tasks they have just learned. “];

NSMutableArray *fruitArray = [[NSMutableArray alloc] initWithObjects:apple,orange,watermelon,nil];
self.fruits = fruitArray;
[fruitArray release];

// Configure and show the window
// [window1 addSubview: info.view];

[window1 addSubview:[navigationController view]];
[window1 makeKeyAndVisible];}

}

all those RootViewController i copied also with Fruit.h.
The project was sucessful without any errors.
The window with table is shown, but when i want to click to one of the rows, nothing happened.

Can u help me

I saw that Fruit.h has been imported in both RootViewController.m and FruitAppDelegate.m – since FruitAppDelegate has been imported in RootViewController (and viceversa), shouldn’t it be enough to import Fruit.h only in one of those 2 files?

Thank you for any help! (And thanks for these tutorials, they’re great.)

Please modify the tutorial by adding pictures to it. Waiting for the next tutorial.

thanks in advance
