I have a view controller that I have a static view up at the top with a button and a tableview that is under it. I'm attempting to create custom cells in the tableview, but I cannot add labels or anything to the cell. Storyboard only allows me to add the labels to the original view or the tableview (but not the cell). How can I get around this?
Here's a picture for reference.
Out of pure "trying everything" I got it fixed by manually dragging a cell into the view and not using the auto generated prototype cells by xcode. It looks like it was a bug with xcode where it's auto generated prototype cells would not let any interaction happen. To fix it, I dragged a UITableView cell from the object list into the tableview and I was able to edit that just fine. Hope this helps someone else out.

I have made a custom UITableViewCell called "SwitchCell" that has a switch.
In iOS9 Only, using Xcode 7 beta, the Content view in the cell is on top of the switch. (See screenshot of View Hierarchy. You can clearly see that the content view of the cell is on top of the other views. ):
So all the touches to the UISwitch are intercepted, and the IBAction does not fire.
In iOS8, this is not a problem. See screenshot for iOS 8.4 simulator. You can see that there is no content view on top of the controls:
Has anyone had this problem?
I tried remaking the NIB from scratch, but the same result occurs.
My NIB is a freeform size view with No status bar. It has two outlets: one for UILabel, one for UISwitch.
EDIT: please make sure to check the answer below that asks to verify that the cell's root view is not just a UIView but a UITableViewCell. This issue may also be a side effect of this.
After more investigation and searching, i found my solution here:
Button in UITableViewCell not responding under ios 7
What fixed it for me was:
cell.contentView.userInteractionEnabled = NO;
This prevents the cell content view from taking over the touch events, even though it's on top of the other views.
This issue was not only happening on iOS9, but on iOS7 as well. In iOS8, the Content view was behind the controls.
Problem can be in .xib file for your cell. When you create cell in separate .xib, be sure to drag UITableViewCell on canvas, not UIView.

I had an issue where my buttons in my custom tableviewcell swift files were working just fine, but then I upgraded to Xcode 12 and then all of a sudden I couldn't access them anymore (meaning my taps were not being recognized). The cell content view seemed to be interfering in the hierarchy and this like saved me:
cell.contentView.isUserInteractionEnabled = false
I put the line in cellForRowAt.
Thank you to #FranticRock
I had this problem when I was reusing a cell as a .xib. I didn't realise but when I first created the xib the default view that it created was in fact a UIView and not a UITableViewCell. It seems that at some stage UIKit adds the content view on top of my other elements and therefore interrupts certain events (e.g. touch events).
I resolved this by opening my xib file and dragging a UITableViewCell onto the canvas and copying my UI elements from the old view to the new cell.
Afterwards, additional settings also became available in the attributes inspector that matched those for a UITableViewCell.
I have a static UITableView. Some cells are set to right detail.
I made UILabel IBOUTLETS for all the right labels and connected them in storyboard. In my viewWillAppear I set the text of the UILabel.
Here is the problem. When my view apppears my text on the label is not visible. But when I touch the cell. The label becomes visible.
This is an IOS 8 problem only. Can someone help me with this.
Kind regards!
There is some bug in Interface builder in Xcode 6.
Change Style of Table View Cell in IB to Basic and then to Right Detail again.
It should work then.
I'm trying to implement segueing from a tableview controller when the user taps the cell's accessory button.
I've searched on here and have some new things to try but I just wanted to ask whether in the storyboard you can actually create the segues from the accessory button, or whether you just need to create them from the tableviewcontroller.
It'll be within the accessoryButtonTappedForRowWithIndexPath that I'll want to act on the tap, but I see some answers on here say that you have to just go from the tableviewcontroller when creating your segues where as another answer said that the sender within prepare for segue would be set to the cell that contains your accessory view.
Whenever I try to ctrl drag from the accessory button in my prototype cell it just gets rid of the already existing on-selected segue I'd setup for that cell.
Just wanted to know for sure, what the best practice was before I started making all my detail accessory segues just go from the root TableViewController and passing through accessoryButtonTappedForRowWithIndexPath's indexPath (or it's row) as the sender to my prepareForSegue.
Cheers
Ok, after trying the suggestions I described in my original question I got the code all working how I wanted. I added segues from the root tableview controller and then performed them programatically within the accessoryButtonTappedForRowWithIndexPath delegate function.
I have a few Table View Controllers doing similar things in my navigation controller so I set about implementing this accessory button workflow in each of them. When i reached the last TVC in my nav controller hierarchy I didn't want selecting cells to go any further, so i changed the accessory type to just detail.
As I wasn't concerned at this stage to have the cell interaction sourced segues overwriting each other I just dragged a segue out from the prototype cell to the destination view controller. Upon doing so within the add segue popup I saw 2 options - Selection Segue and Accessory Action. I'm sure that when I first tried doing this I only had the single Selection Segue choice.
Regardless of whether this was my tired eyes missing it, or Xcode having a funny turn (as it seems to from time to time, being laggy at updated states of various files etc) I can now say in answer to my original question, all you have to do is setup your accessory action segue as required. You can have both selection segue and accessory action segues setup from the same prototype cell, and everything just works as you'd expect.
I've just updated my setup to work this way and all seems fine.

I want to create two PopOvers when at the time button clicked and textField clicked in the same UIView (not ViewController). In those popovers I need to load separate array values. Is there any way to create them and added to UIView?
I already added one tableview for base UIView, so without using tableviews, how can I create UIpopOvers and load the arrays in those popOvers? How to handle the selected rows?
This link can help you to create a popover menu.
Or you can take an UIImageView having shape of popover menu and table view in that, it will be easy to load arrays and to handle selected rows.
I did the same using second method.
Happy Coding!
I'm an sdk newbie, so please forgive the simplicity of this question. Here's the scenario:
I used the Utility Based application template because I like the flip effect of the info button. I changed the info button to a round rect button and made a copy of it that to have two round rect buttons on my first view. I modified the flipside view to display a picture and that functionality works fine. For the second button I wanted it to flip to a tableview underneath the navigation bar. I added a navViewController for the navigation bar and a TableViewController for the tableview. I made a nib for that View, added the tableview, hooked up all the appropriate connections, but when I run it, the flip works fine, but there is no tableview displayed. What I mean by no tableview is it is blank. No lines or anything, just a blank navigation bar at top and blank white space. Please help! Thanks!
With limited information you have given here:
Potential Problem 1 - First Level UIViewController is not linked
If you open NIB file in interface builder where you have drag and dropped NavigationViewController, you will see small disclosure triangle. If you expand that you will see NavigationBar and UIViewController. Select the UIViewController and change it to name of the TableViewController.
The NIB file will change and say View Loaded from YourTableViewController.
Potential Problem 2 - You have to do addSubView or insertSubView and pass in [navigationController view]
If you post some code it may be helpful.
Hope this Helps!
