So, in an iPhone app I am working on, I've decided that the best way to display all the contents to the user is to have the top part of the screen show some information, and the bottom of the screen show different information. However, the bottom part will change sometimes, so I was working on implementing that.
Another app that does this is the MTGLife app, here are some pictures:

You see that upon hitting a button, the picker switches over and displays the log. Hitting the same button switches them back, with a pretty animation. I would like to do the same thing in my application. I'm not sure the best way to go about it though...
I was thinking that I would make 2 UIViews, and then would simply flip between them, but I want to get some opinions first on how to do this, and then a push in the right direction.
Thank you!
The 2 UIViews is a good approach. By using the UIView animations functions, you can switch between the Log and the Picker with the desired transition.
In the UICatalog sample application (see TransitionViewController), there an example on how to animation two subviews

I am losing most of my work time stucking at scrollview,autolayout issues.And now,when i found TNImageSliderViewController.I see that i have hope in scrolling images with no autolayout issue.Thanks to the developer who write TNImageSliderViewController.But,after that I want to do another thing which still keep making me stuck.I tried many tutorial and video and which keep making me stuck.
Here is what i need to do...
1.When I clicked one of my image in scrollview,i want to see full screen of that images i click at another view.
2.That another view should also have capabilities like TNImageSliderViewController which we can slide images.
3.I want to add zoom with pinch or tapped zoom at full screen image that i clicked.
Any Idea?or suggestion or library which it can do it easily and completely with no autolayout issue which we can rotate as we like?
Please help...Please,I really need help.Also all newbie like us might want the same answer like me.
I am trying to develop an application whose view closely matches with groupon app. User should be able to swipe on the screen and the entire screen changes with top pointer pointing to different tool bar entity.
Any pointer of how to go about it?
Take a look at UIScrollView Reference and PageControl Reference from Apple Guides
Hope it helps,
Mário
Looks like a pagecontrol+scrollerview
The complex part is making the toolbar elements move when you are changing the page at a different speed
How do you setup in your application to show little bubbles with text and block the rest of the screen from being used and only allow a small section / button to be pressed. I am wanting to create a walkthrough to show users how to use the application and where to find things within the application when it is opened for the first time.
I would like to dim the rest of the application except for the part I want them to click on. Is there a framework already with these features?
There's no frameworks that provide this functionality, as far as I know.
One way you could do this though is to have a set of overlay images which you overlay over the whole screen the first time the user goes to that screen. To determine if the user has already been to a screen, I suggest you look at NSUserDefaults. To create the overlay images, I'd make the image the full size of the screen (i.e. 460x320 if you are showing the status bar) and then have transparent sections where you want to "see through" to the element below. Add a gesture recogniser to the overlaid image view to detect a tap and then hide the image and set the flag in NSUserDefaults to make it not happen the next time the user goes to that screen.
If you don't get a better answer, you could look at MAAttachedWindow on the page at this link. It's written for Cocoa, not Cocoa Touch, so you would have to convert it. I am considering doing this myself. You might find it to be worth the trouble, but I haven't looked at every detail, yet, so I couldn't say for sure. There are only tow files that are involved (.m and .h).
I want to create view in which when user use in portrait mode then two images scroll in scroll view and when user change mode as landscape then both image views add and become single view. I show this function in restoration hardware apps.I like that so i want to make my apps like that? how do that?
What you ask, is a simple implementation that I could do for you. But then again, you would't learn anything and you would probably come here and ask again. I won't give you the fish, I will show you a way of catching it. Check this tutorial, to learn how to handle rotation and then manipulate your views the way you want:

In my profile you have my personal email, after you learn that, if you need more help, count with me.
When I've learned that I have to write some code to make the iphone keyboard go away. I was quite surprised. I was surprised even more when it become apperent that it is just the top of the iceberg.
What are the expected UI behaviors that aren't provided by system OOTB?
Is the list below complete?
The expected UI behaviors:
Focusing next text field when [done] is hit
Hiding the keyboard when background is hit
Using Touch Up Inside to fire a button action. (To give user opportunity to change his/her mind)
Supporting the screen rotation.
Some of that is silly, but some of it has uses as well.
Focusing next text field when [done] is hit
Which field is "next"? If you have a large form with fields both next to and above/below each other, next might not be so obvious. Even if they are in some linear layout, the iPhone would have to work to figure out which one is next. Do you want to wrap around at the end of the form, or dismiss the keyboard, or submit the form?
Hiding the keyboard when background is hit
I mostly agree with you here, though there are a few cases where this is useless. For example, adding a new phone number in the contact app.
Using Touch Up Inside to fire a button action
This one I really don't get. I can only guess that it's designed to allow you to use buttons instead of the touchesBegan/Moved/Ended methods. I guess it could be useful, but I've never used anything but Touch Up Inside.
Supporting the screen rotation
Many apps just don't work in any other orientation, such as games. If you want to use rotation, you only have to add two lines of code assuming you've done your layout well.
I hope this helps explain some of the strangeness. Aside from the keyboard dismissal, I've never really found anything too annoying. The one thing I wish they supported was using the highlight state of UIButtons for the set state. It would be a quick and easy toggle button, but I've taken to screenshotting a highlighted button and using that for the background image of a selected button.
Want a rounded rectangular button that isn't white? Since that one uses a background image, you can't just click something somewhere that makes it the color of your choice. You have to create your own image or you could even use CSS (WTF!?) to do it.
Unfortunately, the iPhone SDK lacks a lot of helpful things one would think would just be there. However, many people have taken the time to write wrappers for many of these kinds of things to help facilitate development - a quick google search into the functionality you are expecting may turn up a lot of useful answers!
For example, you could make the keyboard go away when you tap outside of it by creating a new view when it appears, and placing that view behind any user-interactable views on the screen. When that new view is tapped, it will become first responder and cause the keyboard to slide away (because the UITextField is no longer first responder).
Such a thing could be easily implemented as a drop-in fix for pretty much anything you'd need it for with very little code.
Still should have been included in the SDK in the first place, though!
