How can i easily make a tableview readonly but scrollable?
i tried to set tableView.isUserInteractionEnabled = false.
However, it disabled the scrolling action either.
I'm not sure I understand your question but a table view has no default interaction on it unless you write it.
You create the table view, configure the data source and the cells and thats it.
You can add behavior to it so when you tap on a cell allows you to navigate to detail, delete it, etc.
If you don't want the cells to react visually when the user taps them, just set the selectionStyle of the UITableViewCells to UITableViewCellSelectionStyleNone

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 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 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.
In my normal tableview I got a bunch of switches and segments, and I don't want them to be selectable, so I set:
tableView.allowsSelection = FALSE;
Now one of the cells, I want to point to a new view, and thereby make it selectable. But there's no cell.allowSelection or anything, how do I solve this? How do I make it, so that it can be pushed and direct you to another view? I don't want them all to be selectable, since that's ugly...
There is not an allowsSelection property on cells, but there is a similiar property.
Set cell.selectionStyle to UITableViewCellSelectionStyleNone for cells you don't want to the user to be able to select.
(You will have to set table.allowsSelection back to YES.)
Configured this way, you'll still get -tableView:didSelectRowAtIndexPath: for any cell the user taps; just ignore it for cells that you don't intend to be selectable. (Thanks tc.)
Ok. I have made a custom cell for my table, and it contains a text view. When I have multiple lines in the text view, I can scroll up and down, but in doing this the table also scrolls. How can I stop this behaviour? If anyone needs parts of my code or further details, please just ask. I am more than willing.
Thank you for your help
I suggest you to move text edit (write) behavior to another view controller. If you need read-only functionality from it then just increase cell and textView height.
Did you try setting canCancelContentTouches to NO? It's a property of UIScrollView, from which UITableView inherits.
Your custom cell seems to pass on touch events to its container class as well as utilizing them itself. Did you implement any - touchesBegan:, - touchesMoved: or - touchesEnded:?
If you make use of a touch events, you should not pass them on in the responder chain.
When the text view has focus, set scrollEnabled=NO on the table view. You may have to manually remove focus from the text view and restore scrolling when a touch occurs outside the text view.
