I created a Custom UITableCellView for my application. Each cell has two buttons. The problem I am facing is that the cell itself is selectable which leads to a confused user and poor design. How do I disable the interaction for the cell but keep the interaction enabled for the UIButtons in the cell?
Thanks!

You can set the cell.selectionStyle = UITableViewCellSelectionStyleNone; and be sure to keep your didSelectRowAtIndexPath unimplemented. That means that your cells will not be interactive, but you can still get messages from your buttons.
Apart from that, of course I don't know what you're trying to achieve, but remember that you can use a UITableViewCellAccessoryDetailDisclosureButton as an accessory view, which is a different "button" from the cell itself. More info here.

I have a UICollectionView which allows for a user to select a cell and upon doing so view 'A' will appear. I am wondering if it is possible for the subviews of this cell, ex: UIlabel and UIImageView to provide a different functionality for when they alone are selected. For example, if the UIImageView is selected, I want to segue to view 'B' as opposed to 'A'.
I have attempted to implement a UITapGestureRecognizer for both the label and the image, however, the cell's functionality overrules and the resulting view is still 'A'. Any ideas?
Thank you in advance.
What you want to achieve is possible through delegates if you don't have custom cell make a custom cell class then inside custom cell declare your protocol
I assume you have to disable the default behavior of the collection view cells:
cell.selectionStyle = UITableViewCellSelectionStyle.none
However, if you set that and you encounter an overlap issue, please take a look at the 'cancelTouchesInView' property of the 'UITapGestureRecognizer'. Basically, by setting that to false, you allow the children to also receive touch actions.
Furthermore, do not forget each gesture recognizer should have it's own method for you to be able to segue into two different places.
I am just thinking. Suppose, i have a tableview which have custom cell. It's simple. But My idea is that, when i click a tableview cell then another tableview is appear under that tableview cell, and again i click that cell then that sub tableview disappear. Similarly when i click second cell than work same. Is it possible? Please Provide me any idea or reference.
This is entirely possible, you're talking about Expandable cells.
My example here
The general idea is that your custom cell has a tableview at the bottom of the cell, and what you do is just change the cell height to display said tableview, on tap.
It's not easy, I'm not gonna lie it took us a while to do it, but we managed, and I'm telling you, it's very possible.
You can find a lot of help using the Expandable Cell keywords.
Note that you're gonna find yourself handling a lot :
What to do when the expanding cells is shown off screen?
What to do when you're expanding the first/last cells ?
What to do when expanding another cell ?
What to do when scrolling inside that cell (a scrollview inside a scrollview !)
There are many cases where it'll work, but won't work fine, and there is gonna be a lot of fine tuning. Specially in our case where we have rounded corners, but only when the cell is expanded, and not in cases where it's the last or first cell (next to section header).
They look cool and make you feel proud, but don't say to your PM it'll be done in a week, because it's a pain to build.
If you want to show additional cell information, you can add more cells after the cell indexpath you have clicked.
Create a custom table view cell classCustomTableViewCell by subclassingUITableViewCell class. And system will generate CustomTableViewCell.h, CustomTableViewCell.m, CustomTableViewCell.xib files for you.
Add protocols UITableViewDataSource and UITableViewDelegate in your CustomTableViewCell.h and implement the required methods in CustomTableViewCell.m files
Add a method for setting datasource and use the datasource for updating the table.
NOTE:
Handle table-dequeue mechanism properly, otherwise you will end up
with weird issues that may take time to investigate and resolve.
If you use this custom cell for all the cells in your parent table then the gestures will only listened by the child table. So plan for that too.

I'm building an app where I've got cells that expand, similar to when you create a new event in iOS' built in calendar app. One of the expanding cells have a disclosure indicator set in storyboard, but return nil when logging it. I've tried to set it both in StoryBoard and like this:
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
and I'm trying to fade it out like this:
self.cell.accessoryView.alpha = 0.0f;
but it doesn't work as it's nil.
Can someone help me with this? Why is it nil? I'm using StoryBoard with a UITableViewController that's static and grouped.
Thanks!

You'd have to provide your own accessoryView. accessoryView will be nil if you're using an accessoryType.
Remember to add a little logic in tableView:cellForRowAtIndexPath: to decide whether or not to show your accessoryView as well since the cells get reused.
I am learning about TableViews in Xcode right now and I am having trouble finding some info on TableViewCell accessories.
My goal is to have a MasterTableView and a SubTableView. When a MasterTableCell is tapped to take the user to the SubTableView. But I'm stuck with something simple like showing a '>' on the right side of the cell to show that it has a SubTableView.
Do I need to design my own button? I thought there was a navigation image already available to me in the UI storyboard maker but it won't let me drag and use it in my custom cell I'm making.
Any thoughts or links to documentation would be great. I've looked in the developer library and all it tells me is that it is possible, not how to do it.
Thank you in advance.
If you are using a Prototype Cell in the Storyboard, just set the "Accessory" type in the Attributes inspector to "Disclosure Indicator".
If you create the cell programmatically, set
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
From the documentation:
UITableViewCellAccessoryDisclosureIndicator
The cell has an accessory
control shaped like a chevron. This control indicates that tapping the
cell triggers a push action. The control does not track touches.
I have a Static TableViewCells on a storyboard. There are just labels in those cells. I would like to fire IBAction event upon touch. What I am doing right now is create a full-size white button and linked to IBAction. But it doesn't show highlighted color when the cell is selected because cell is behind the button.
UITableViewCells have a delegate method specifically for handling row touches -tableView:didSelectRowAtIndexPath:
If you need a custom button over each cell, subclass UITableViewCell instead of going through a storyboard. As much as they may be a timesaver, storyboards are really a limiting factor when it comes to nitty gritty iOS programming.
Try adding this in your cellForRowAtIndexPath (when you initialize each cell):
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
Does this fix it?
