I am creating an app in which user has been provided with the feature just like radio button.
I had added the button in tableview cell and its also acting like radio button but not in all cells working only in some of the cells.
Also the cells on which feature is working i have problem that it get deselected when i scroll the table view.
Please anyone help me out or provide a snippet.
Appreciate your help.
When the UITableViewCell scrolls off the screen, it is actually reused by the UITableView. You will need to account for this by saving off the state of each button in your model the moment they are pressed and then during tableView:cellForRowAtIndexPath:, read back in that value and set the button's state.

I have a quick simple question for you. I have a tableview and want to add a button(which is a star image) to every cell. Thus in the storyboard I drag a button into my tableview prototype cell. I can see perfectly that there is a button in the main.storyboard in my cell but, when I run the app no button is appearing in any tableview cell. How can I fix this issue? I'd appreciate any help!!
You need to create custom class for tableViewCell, and with this class, you can add your button. It's similar like in this tutorial, just instead of images, you can add buttons. On youtube you can find some good tutorial as well.
I am working on a app which includes table cells. I want that when i swipe table cell it shows two options, first about that cell value and another for delete that value. How can i show that in a way that the cell value shows in half of cell and the options show in half of cell.
Thanks in advance.
There are an out of the box solution, called HHPanningTableViewCell. It does exactly what you need!
HHPanningTableViewCell is a UITableViewCell implementing "swipe to reveal" a drawer view. Such a view typically holds action buttons applying to the current row.
This library, SWTableViewCell, should help you:

An easy-to-use UITableViewCell subclass that implements a swipeable content view which exposes utility buttons (similar to iOS 7 Mail Application)
You have to create a custom cell and override Apple's behavior which is swipe left to delete and then show your options. You can add gesture recognizer to the cell and on swipe to left animate the cell content view and animate in your option view or however you like it to be. I can write up an example code if you need.
I need this kind of component to my iPhone Application. How could I Added to this to my project.
after i click that black color I need to animated it to left side and show next one.. like that
Try a tableView with one row and one section. Then the action of clicking on the row can trigger the delegate method of the tableView and use that to do whatever you like.
Alternately, you can make this a button with a custom view and swap out the view each time the user taps it.
I would like to do pretty much what the Mail Application does: that when I select Edit, instead of the usual Delete Button, Radio Buttons appear on the side that may be checked by the user, then the user may click on a Button to take an action on the marked cells(any kind of action not just delete). Is there any apple sample code that does this?, can anyone please provide some code or documentation on how to do this?. Thank you.

I haven't done this so all of the following comes straight from the documentation. This is how I would do it:
Overwrite your view controller's setEditing:animated: method to display one or more buttons to execute your batch action (just like Mail.app does) when the table goes into editing mode.
Use a custom UITableViewCell subclass for your cells.
The key is to overwrite willTransitionToState: in your custom cell class. In this method, add a custom subview containing your radio button to the cell.
Overwrite layoutSubviews to position the radio button and the rest of the cell's content in the cell.
In tableView:didSelectRowAtIndexPath:, differentiate between the normal and editing states. If the table is in editing mode and the user taps a cell, mark it as selected (modify your radio button subview accordingly) and keep a record of all marked cells.
Here is a good article about doing a Mail-style multiple selection:

I want to pop up a view when user touch on the screen,it is just like a tableview cell with disclosure accessory button.It has text showing message and when the user press the accessory button,it will take some action.
I have seen a similar example in iphone cookbook, it create a UICalloutView:UIControl,
but it seems that it uses some private API.
can anyone tell me how to achieved this?
Well, it's probably private. You could printScrn the accessory and add it as a resource to your project, and use it as an image.
