iphone - Navigating between UITextFields? - iphone

I have seen a lot of iphone apps which provide an easy to use navigation controll for text fields, which contains next previous and done.
What is the technique for this? any
sample code?
they also scroll the screen until
the selected textField is placed on
top of the keyboard, how do they do
that?

Sorry I don't have direct answers, these are the best I could find off the top of my head:
For 1, take a look at first responders, it seems to be what you're looking for.
For 2, you will have to make it manually. See this article.

Is it possible to move the tab bar to left and right direction in iPhone

Im developing a tabbar application.
There are almost 7 tabs in this app.
Usuall when we add more than 5 tabs a "more button"will come and rest of options will come under that "More option".
But i found a very interesting app in app store and they are moving the tabbar to left and right(just like we do in scroll view) like in the image below.
How can i implement this.
Can anyone help me with this please.
Thanks in advance.
As far as I can see, it's 2 custom UIButtons placed over the tabBar that may programmatically rearrange the tab options on their IBActions. What makes me say that is that the highlighted area of the last tab is just normal, and the arrows does not seem as well placed as what Apple could have done by standard.
You can use custom tabBar, like InfiniTabBar, nice and functional.

iOS 4 - How to add table view to a tab bar application

I am new to iPhone programming and am having a really hard time trying to figure out how to add a table view to a tab bar application. There are not many tutorials on this for iOS SDK 4 and the Apple documentation is very light on details. Since I am new I would really like some tutorial that has screenshots (or at least clear instructions) when it comes to things being done in Interface Builder (like making connections between the objects and File Owner, etc), usually lot of tutorials/blogs gloss out these details.
What I am trying to do is create a tab bar based application with 3 tabs (this I am able to do). The first tab needs to display a table view with the header having 2 buttons (one on right and other on left, with the title in middle).The title is actually today's date, obtained from the phone. Clicking either of the header buttons should take you to another table and the title should be yesterday's date (if left button is clicked) and tomorrow's date if right button is clicked.
Can some one please suggest me a good tutorial for this. I am thoroughly confused by the Interface Builder (especially how to create connections).
The only page I remember frequenting on the past, is CocoaDevCentral.
Personally, I learnt how to use Xcode through video tutorials, so I recommend you to start searching there. Also, to help you with your search, always look for the full name of the objects involved, for example: instead of searching for "tableView", look for "UITableView", apple's notation is very particular and helps narrowing down the result.
Finally, ignore the nay-sayers about Interface Builder, you should give it a try, and see if it fits your style. For instance, I like being able to get a look at the overall design, as I usually help with the design.

Sliding UITabBarItems in UITabBarController

I have a UITabBarController as my rootController with 8 UITabBarItems. and I want to show just 4 UITabBarItems in my screen. By default all my other tab bar items appear in a small tabBarItem called "More" and you can select the other 4. But I have seen some apps that implement a sliding UITabBarItems with a slide icon instead of a "More" icon.
How can I show just 4 at a moment, and I slide the TabBarItems, and so that I can select the other tab bar items ?
~ Something like this ~
And then I can slide to the next 4 sets by dragging
It would be helpful if someone could point me in the right direction.
There is a nifty little github project that could help you... check it out: https://github.com/iosdeveloper/InfiniTabBar
This is not currently a built-in option for UITabBarContoller.
One way to approach the problem is to add a UIGestureRecognizer to the tabBar.view, and programmatically adjust which 4 options are available on the screen. You can add an animation to make it smooth or have a little bounce as it slides.
iPhone users are usually very picky and attached to Apple's UI Guidelines. Although you can pass the Apple verification, you probably wont be able to pass users' (meaning bad reviews and ratings). So I recommend you to re-consider your tabbar structure and use "..." More instead of sliding it... You can always override stuff in code, but then they wont work smooth with InterfaceBuilder and in the end you will have more trouble than you'd expect.
If you have similar tab items merge them and use maybe a segmented control or something to visually distinguish them. Or use a central navigation screen in which you can put 9 maybe more icons in a grid...
The first solution to your problem may not always be the best way. Well, it is very rare actually...
You have to write a custom control for this.
I wrote one for showing a horizontal menu. You can probably modify that to fit your needs.

How can I create a bigger UITabBarItem?

I'd like to re-create something similar to Instagram's tab bar for iPhone, which has a "custom", bigger tabbar item in the middle of the tabbar (see http://cdn.venturebeat.com/wp-content/uploads/2010/10/instagram-screenshot.jpg)
I can think of several approaches, but was wondering if anybody has suggestions on an easy way to accomplish this.
check out this post. It explains how its done.

Mobile Safari iPhone Development - Multiple buttons in a row

I'm an iPhone developer, but new to web development. I've done some basic HTML websites and made one in iWeb as well. I'm trying to branch out to mobile web development now, so I checked out Dashcode.
Anyway, I'm trying to put a Call Button, Mail Button, and Map Button in horizontal alignment. I realize that I can add a Column Layout and have two buttons in a row, but that's the most I've gotten.
Any ideas? Thanks!
Thomas
Edit: I still haven't figured this out yet. I was given advice about a fixed position button bar, but I am not sure how to implement it. I've been looking at code, but haven't gotten it yet. Still trying though. Any help is appreciated!
What i do usually is to select the element you can't align horizontally and then go to the inspector -> dimension tab and in disposition you select fixed absolute.
This should work but beware because if you've the intention to change element's place dynamically you may have some surprise...
I think you are looking for something like this.
A fixed position button bar is created with several buttons side by side.
