I need to create a screen with a Listfield and three buttons at the bottom of the screen. I tried to make a status bar and put three buttons into. The screen is displayed correctly but I just only be able to click on that buttons when traversing all items in Listfield. Please give me some helps!
You will probably need to extend the ListField, intercept the gesture you want to cause a traversal from the list to the status bar (before reaching then end of the list) and change focus programatically.

Can anyone tell me that what is the ui element use at the right top of the application? The user is able to swipe left and right to swipe between the view controller and the green bar at the bottom of the icon will animate.
Actually it's not only one element. In my app,I used three buttons and one cursor view to do this.
I want to implement a search bar in my app which mimics the one on iOS 7's home screen. When I pull down, I want it to bounce down while having enough room on top for the status bar, and I want my current view to move down to make room for the search bar as well. How should I go about with this?
My current thought is to make a new UIView class, add a UISearchBar to it and add that view to my current view (So that I can scroll down to display the search bar). But is there a better way to do this?
This is how it looks like on the iPhone home screen

As you said you could create a UIView with a search bar in it. Add it to your main view and set your searchView origin.y to be less than 0 so it will hide below the top of the screen.
Next you could use a UIPanGestureRecognizer to track the dragging of your finger and update the origin.y of your searchView while you drag..
I have used two uibarbuttonitems and added a flexible style between them to adjust them at left and right. But when I click just near the buttons the respective actions are got called, even I don't click on the button (here fox example I clicked approx 20px before the right bar button). can any one explain why the action is performed when i click outside of the button not inside it. I check it with custom uitoolbar also and it is show the same problem.
Cocoa-Touch controls usually have larger active touch areas than they are visible on screen. Especially with bar buttons, the touch area can be dynamically enlarged if there are no other bar buttons nearby.
I'm making an iPad app, and basically, I want to make a tray that pulls out from the bottom of my app, and I'd like to have a little tab at the bottom of the screen that if you pull, it brings up an image, and the image's height would match the height you pulled the button to. It's a bit like how the notification center works, except the tab is always visible.
So my question is how would I have the image follow the tab as it moves vertically across the screen? I would assume using a UIButton for the tab and a UIImage for the tray would make sense, and I have some code for making buttons move, but how can you make one object follow another?
Thanks for your help,

I wouldn't use a button for the tab -- just a regular old view.
To make your image follow the tab (however you implement either of them), simply animate them both together. That is, if you create an animation that moves the center of the button to the Y-coordinate of the user's touch, you can at the same time move the image vertically by the same amount. The two objects will then seem glued together because they move together.
I have implemented a customized ListField with some LabelFields. Here is the screenshot.
The problem is when I scroll the ListField, the whole scroll getting scrolled. Like this Screenshot..
I want the headerfield and the Field between header and the ListField to be stationary and only the listfield get scrolled. How can I achieve this?..Please help me...
Use setBanner(Field field) to create an area at the top of your screen which will always be visible.
By the way, you almost certainly don't need a 'Back' button in the top bar (like you would on an iPhone app) because all BlackBerrys have a physical back button for this purpose. The default action for it is to close the current screen (by popping it off the screen stack) and returning to the previous screen or closing the app if there are no more screens.
You can use 2 different managers and let only the manager that has the listfield to scroll
