I hope someone can help:
I am using a popover style container for an iPhone app. I am trying to put a UITableViewController into the container - but keep getting the NSInternalInconsistancyException error - stating that I have not set up the tableviewcontroller with a prototype cell etc - which as far as I can see I have. The TVC I am placing in the container is in the main storyboard but not connected to any other views via segues.
Should I be using seperate nib files for this TVC and TableViewCell? I don't have experience with doing this - and my attempt earlier today to solve this problem didn't work!
Setting up the UITableViewController programmatically sorted this problem out. Also, ensuring that null tableview cells are set up correctly when dequeing.

I had a tableviewcontroller with a SearchController I managed programmatically. For some reasons, I need to have a storyboard to display things a bit differently not anymore a tabéeview in full screen.
Everything is going fine with a container view inside my storyboard. The container view is linked to my custom tableviewcontroller which was managing my searchbar. When I instantiate an object, I can see my custom tableView (with a searchbar lying at the top) in the same way it was before.
I would like to remove the search bar embeded to my tableview (i.e in my tableviewcontroller) and add it directly in the storyboard (to have more at the top of my screen with free space between the search bar and the table view. I tried to insert a searchbar and displaycontroller but I am stuck in the sense I cannot link the searchBar to my tableViewController.
How can I do to link the searchbar in the UIViewController to the tableviewcontroller in the containerview? My tableviewcontroller conforms to the protocol necessary to have a searchbar working still there was no problem when they were not gathered inside a storyboard.
Here is an image if it can help.
If anyone could help me to link the searchbar and the tableviewcontroller...
Thanks!
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 am trying to create a simple app which uses a main view and has a smaller subview within it. I need to have buttons in the subview and I am having trouble getting the connections for the buttons to work. I have done the following:
Create a new View-based project, which gave me the ViewController.h & .m, the MainStoryboard.storyboard and the AppDelegate.h & .m.
Create the subView using NewFile - Objective-C Class - then naming it "subView1" and making it a subclass of UIViewController and checking the with xib check box.
This gave me the subView1.h &.m files and the subView1.xib.
I then re-sized the subView in the xib, by setting it's size to "FreeForm" in the attributes inspector and then specifying the width (to 280) and height (to 300) in the size inspector. I also change the background colour to differentiate it from the main view.
I then dragged a UIButton into the subView and connected it as an IBAction (which i named "clickButton1") to the subView1.h file using touchupinside.
For testing purposes only i then used a simple NSLog to check the functionality of the button which i placed in the subView.m file as follows:
-(IBAction)clickButton1:(id)sender {
NSLog(#"It Worked!");
}
In my ViewController.m file in the viewDidLoad i then added the following code to add the subview to the main view:
subView1 *sv1 = [[subView1 alloc]init];
sv1.view.frame = CGRectMake(20,120,280,300);
[self.view addSubview: sv1.view];
This all worked fine, and when i run the app i get the main view and the subview appear as expected. The problem is when i click on the button which is located in the subview it crashes with the following error:
Thread1:EXC_BAD_ACCESS(code=1, address=0xe00000008)
From what i have read i believe this may have something to do with how I am adding the subview and the fact that I am using ARC. Something about once the subview is added it is automatically released and therefore all buttons/connections etc within the subview are lost.
So my two questions are 1) Am i missing something silly here and is there an easy fix? and 2) Is this an appropriate way to create an app which uses subviews with buttons within them or is there a better way? Thanks to anyone who takes the time to answer!
I tried to reiterate what you said.
So you first made a View-Based Application (checking the "Use Storyboards" checkbox), and you put a button in the storyboard. Then, you control-dragged the button to the "ViewController.h" file. If that is right, you should just be able to put
NSLog(#"It Worked!");
in the method implementation (at least, I could do that)
I am trying to build an iPad app set-up as a split-view, but on the detail page being able to drill down like a navigation controller.
An example of this working is the setting app on the iPad where if you select the 'General' tab you can then drill down on the detail page from say general > network > VPN
Any help or tips on this would be great. I thought it might be two navigation controllers on the root nib, but couldn't get this working.
you mean like General -> About ->.. (in ipad simulator) right .
if all your detail view needs the TableView, then its better to make your detailviewcontroller as the subclass of UITableViewCOntroller.
OR If you need different views when click on the cells of rootcontroller(left pane)
Create a method in DetailViewController say setDetailView{}. And call this method when click on the cell of RootController
inside this method,
remove all subviews from detailview
create UITableView and set its delegates
on tableview didSelect method, we can push other UIViewController instance
[self.navigationController push...]
Hope it helps.
I am attempting to make an iPad app. I started out using the splitViewController app template, and realized that was a bit restrictive, so I've started moving everything over to a regular View-based app template. However, I'd still like to have a table on the left with a different view on the right. I have a NIB with a tableView on the left and a view on the right. The tableView is still in a separate class. Is there a way to load that view into the tableView of the NIB?
I'm trying code that looks like this:
rootViewController = [rootViewController initWithShow:assetOneID];
[rootViewController.tableView reloadData];
[htmlPage viewDidLoad];
htmlPage.myContent = rootViewController.tableView;
[htmlPage.myContent reloadData];
htmlPage is the main page with the table and the other view. myContent is its table. rootViewController is the class that I used for the table of items. When I try to run this(and I know there are items in rootViewController's table through using NSLog), nothing happens. The table just stays blank, even though it should have the title of the item in rootViewController.
I'm probably missing something obvious here, but I've tried many different things and none of them have worked.
Thanks in advance for any help.
Delegation sounds like a solution but, regarding the blank tableview - Have you set the delegate and data source for the tablview in IB or programmatically?
