I know how to use checkmarks in a tableview when it is not in edit mode. But once in edit mode, it seems that it won't allow me to add checkmarks. Any ideas how to get around this?
Detail accessories are pushed offscreen during editing. This is native behavior and unless you have a peculiar use case it's perfectly fine. If you are editing to sort by checked vs. unchecked, do that automatically. If you really need to, poke around in the methods of your table's delegate. Protocol reference.
Perhaps you can use the built in UIImageView that is on the cell so that when you are editing, if your table allows the editing of multiple rows, when the user taps the cell, the UIImageView is filled with the image of a check mark, but when the table is not in edit mode then the UIImageView is empty.
You can use the allowsMultipleSelectionDuringEditing property of UITableView to decide whether cells are selectable in editing mode.
Then calling indexPathsForSelectedRows will give you the indexPath of the rows the user has selected, and then perhaps you can have some logic to edit the cell's UIImageView property.
A bit hackey, but I hope this helps!

I am trying to use the the dragging functionality that UITableView offers while in editing mode to rearrange some custom views in the cell.contentView. I am successfully getting editing mode turned on after a long press on the cell and turned off following a reorder.
Here is a picture of how I have things set up: http://cl.ly/image/081k3G0A3f2I
The problems I have are:
The contentView indents no matter what I set ShouldIndentWhileEditing to.
I would like to get rid of the delete control and the drag control.
The whole contentView should be the drag area instead of just the little drag control area.
Help with this would be appreciate. Thanks.
Yes, you can customize the look of the drag controls. Try overriding layoutSubviews. In that method, check for editing status and draw /position your elements accordingly.
You can't get rid of the drag control if you have enable row reordering. The API does not allow any customization of row reordering. The only solution would be your own custom table type view.
You can get rid of the delete control. Simply return UITableViewCellEditingStyleNone from the tableView:editingStyleForRowAtIndexPath: delegate method.
i have a UITableView where i want one cell(database row) needs to be default,
So I am thinking of two options
in TableView upon clicking a cell, change accessoryType to mark just like ringtone selection in settings app
when user enters data, add an option (like radio button or segmented control) to make that cell (database row) as default one
I feel first option is good but we can implement code for that only in didSelectRowAtIndexPath but i need to jump to another view when user click on a cell.
So please give me an idea how to accomplish this
One idea iam thinking is adding an edit button but don't know whether its possible or not.
Thanks
Not sure if i understand your question correctly , but according to what i understand you want a table view in which many values will be there , and you want one value to be default which can be changed later.
According to me these ways would be pretty good,
Changing the accessorytype of the tableViewCell. (Most common way)
Changing the Highlighted property of the cell on loading the tableView.
Adding some image then setting the image as the background view of the selected cell.
Adding custom image view (such as tick or something and adding to the cell).
this code can be put in the viewDidload so your default selected value appears.
Hope this helps.
Don't know what you mean by default. I'm assuming you mean already selected. You might just want to set the accessoryType to the checkbox. That would be Apple's way of doing it.
I have created a UITableView that is of type UITableViewStyleGrouped. I have then created several different sections with a few rows in each. Within each of these rows I have created a custom UITableViewCell that contains a UITextField. I also have one UITableViewCell that contains a UITextView.
I have also implemented a UIToolbar that appears on top of the UIKeyboard that allows the user to move through the UITextField's by pressing previous or next.
The issue I'm having is two-fold:
I need the UITableView to scroll so that when the next UITextField (or UITextView) becomes the first responder it is visible (even with the keyboard being displayed).
When a UITextField (or UITextView) is selected (without using the previous and next buttons) is should adjust so that the field is visible above the keyboard.
I have looked around at lots of different tutorials however none of them have resolved my issue. Any help you could offer would be hugely appreciated.
ADDITIONAL INFO:
I'm 100% certain that my app used to do all of the above automatically, however I seems to have stopped doing it now and I don't understand why. Is there a reason why this may of happened? Is there some function or something that I may have changed that would destroy this behaviour?
Probably no use to original poster now, but those having an issue like this where it once did work and then stopped...
check you don't have a:
- (void)viewWillAppear:(BOOL)animated
in your UITableViewController subclass!!!
using viewWillAppear in a UITableViewController breaks the "automagic tableView scrolling up when keyboard appears" behaviour.
I only found this by comparing laboriously an old version of a project where it did work with my latest source where it had stopped working.
Check out TaggedLocations sample code from apple. It does the same thing without any extra manipulation.
The key is that your viewcontrollers are following the standard. i.e you are NOT having container viewcontrollers such as UINavigationController within UIViewController.
You have to update tableview Frame yourself programatically...
and i am 100% sure that if you are 100% certain that your app used to do all of the above automatically ...than it is not your app.
Check the docs..here is the link
https://developer.apple.com/library/ios/#documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/ManageTextFieldTextViews/ManageTextFieldTextViews.html#//apple_ref/doc/uid/TP40009542-CH10-SW1
You will have to register for keyboard notifications..and then update your tableview frame.
And for next and previous.. you have to programmatically check which textfield became active..and then set the frame accordingly.
I have a table view with different cells and basically I would like an edit button which would then make those red circle appear in each cell and be able to delete them. I already know how to make the "Edit" button appear and also I have overridden the commitEditingStyle method for the table view so I would like to know how to link the button to the action which trigers the red circle and how to make them appear and finally how to actually delete the cells thankyou :)
The editing style on your table view cells should be set to UITableViewCellEditingStyleDelete, and then you just need to make sure to call setEditing:animated: on your table view. UITableViewController can help provide a lot of this functionality pre-baked.
That's actually done through an undocumented API (though I'm not quite sure why) - using it would probably get your app rejected.
However, lots of apps simulate this functionality with their own code - you'd basically define a custom UITableViewCell subclass which changed its background color / toggled that extra red circle image when tapped, keep track of which cells had been tapped, and finally delete them all by calling deleteRowsAtIndexPaths: on the table with the collected list of rows.
If I create a UITableViewController - drilling down works as expected. If a user selects a cell and I implement 'didSelectRowAtIndexPath', the cell flashes blue and the next view shows up.
But, if I include an 'edit' button (self.navigationItem.rightBarButtonItem = self.editButtonItem), when the user clicks 'Edit' - the mode correctly changes (all the cells indent and paint an appropriate editingAccessory), ... BUT, the cells are no long 'selectable'.
IE: while in edit mode, when a user selects a cell, nothing is happening. No blue flash. No invocation of 'didSelectRowAtIndexPath', nothing.
When I open the iPhone example 'iPhoneCoreDataRecipes' (as provided in the SDK docs), sure enough, they have a RecipeDetailViewController - that, when put into edit mode, still allows you to drill down. I've downloaded and built their example and it works just fine. I can't seem to find any trickery in their code to enable this 'selectable cell when in edit mode behavior' but I'm just not getting it when I do it.
Thoughts?
Thanks for any time,

UITableView has a property allowsSelectionDuringEditing for this.
IMHO it should have been YES by default.
You have to set the allowsSelectionDuringEditing property of UITableView to YES.
The default value is NO.
It can be changed in Storyboard:
