Basically what I want to do is have a main screen that the user can enter search criteria and then the next page will bring up the search results in a long list. The user can think click on a row in the table that will take them to another UIView.

UIView -> UITableView -> UIView

Wanted to add some thing. If you get error about “@synthesize view2ViewController” not declared after your build and go then recheck your view2ViewController.h file again

One thing that I’ve come across is the naming conventions that iPhone (and maybe Apple?) developers seem to use, and that is just changing the case of a variable two, maybe three times. Over and over I see this in blogs, tutorials, and even the iPhone SDK (maybe that’s where everyone got it from??)

Terrible programming practice, IMO, and makes readability of the code incredibly difficult, not to mention the confusion the IDE has when trying to guess which variable you want.

If the nature of the language is that it’s case sensitive, that’s fine, but essentially changing the meaning of a variable because of the case doesn’t make any sense. Could you image the confusion if these three sentences all meant something different:

The sun is yellow.
the Sun is yellow.
The Sun Is Yellow.

While the first sentence is the correct case, all three mean the same and everyone knows what I’m saying by looking at any three.

Anyway, my two cents. It’s an interesting platform to develop on, and I would image Apple will hopefully increase the ease of use of the IDE. For example, instead of wiring things up manually, there’s no reason I shouldn’t be able to click on a button (for example) in UI builder, choose an event, and the function outline be automatically written and wired for me instantly.

i hv a view with a button,

wat i am trying to do is,on button click ,new view should come “with tab bars.”

i created 1 tab bar controller and added correspoing nibs to tab bars.

but i m not able to call this tab bar controller view from my previous view whoch is containing a button.

hope i sound clear,with my problem.

looking forward for a quick reply

“This demo is broken with Snow Leopard and Xcode 3.2. As Chris and Vamsi point out above, you can’t connect the view2’s referencing outlet to the File’s Owner. The connection attempt is rejected, not sure why…”

This would have been a nice tutorial if it worked .. should provide a warning so people can skip this or update your tutorial..

I’ve tried this out but keep getting an error when navigating to the other view, When I go to debug it says:

TERMINATION_DUE_TO_UNCAUGHT_EXCEPTION…

and focus on 0×01c1b004 leave

I’ve looked over the code again and again but since I’m new to this can’t seem to find why this is happening. :S

Any thoughts?

In RootViewController.m, don’t we need to release view2ViewController when the RootViewController itself is released?

- (void)dealloc {
[view2ViewController release];
[super dealloc];
}

Not sure if you are still addressing questions, since I haven’t seen you respond since Sept, 2008, but I was trying to follow Uhu’s explanation of iterating the cells and could never get it to work. If you have time, (or anyone else does) it would be nice to see how that got implemented . Most specifically, the iterative loop in the – (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
method to generate multiple rows.

Thanks!

I tried to do a transition on a window-based app & nothing seemed to work.

Can you provide some tips for transitions outside of navigation-based apps?

Thanks,

FYI, in version 3.1.2, it was necessary to uncomment the viewDidLoad method.

First thanks for the great tutorials…

Something I don’t understand in this one… it’s about the back button…

How come setting the title property of the rootview make it a button that goes back to this view….

maybe a stupid question but I don’t get it….

Thanks for these tutorilas, they are really great!!

I do have some questions for you:

1) The bundle thing in the constructor for view2, what’s that?

2) I notice there is an asterisk in the variable name sometimes, and sometimes not. This confuses me. Is it when declaring variables they must be with an asterisk (*)?

3) In didSelectRowAtIndexPath you first construct an instance of View2ViewController named *view2.
Then you assign it to the property view2ViewController, which makes perfekt sense. But then you release view2, which I dont understand. Here’s why:
The programming languages I am used to (Delphi and C#, I know, both running on Windows), would treet this as two pointers or handles to the same instance. By releasing either one of these pointers [view2 release], the object would be released from memory and the other pointer/handle/variable/property would be pointing to invalid or undefined memory.
So the question here is, does the assignment in fact make a complete copy of said instance?

4) The self keyword in RootViewController, which object does this refer to? Is it the application itsself, or the instance of the RootViewController?

Once again. Fantastic tutorials!!

So I updated this code to initWithNibName:@”View 2″ and it worked.

Thanks for the tutorials!

The only hiccup you may see is the deprecated command setText. Darrel’s code can be updated to the following if you want to get rid of the pesky warning message during build&debug:

[cell.textLabel setText:@"Next View"];

Otherwise, it still runs just fine.
