I recently updated our ObjC app on XCode 9. Everything was ok (I even updated to iPhone X new layout), there has been just an issue in one of the viewControllers (built in IB). This viewController, which shows a tableView with news, can be accessed from 2 sources:
From appDelegate if a Push Notification informs about new news. In this case, a right navBarButton is unhidden so the user can dismiss the view
From a specific section, where a normal back button is used
When I try to open the viewController from the second case, the app crashes with the next message:
2017-10-17 12:53:26.747396-0500 verifica[17299:1270771] * Assertion failure in -[_UIButtonBarButtonVisualProviderIOS _addConstraintsForBackgroundImageWithOffset:isBackButton:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3694.4.18/_UIButtonBarButtonVisualProviderIOS.m:485

libc++abi.dylib: terminating with uncaught exception of type NSException
The app worked fine before XCode 9. I've run it in the simulator (with iOS, 10.3, 10.3.1 & 11) and on an iPhone with iOS 11, and crashes all the time for case 2.
I've searched several of the terms referred in the console, but the only similar was http://www.cocoachina.com/bbs/read.php?tid-1726269.html, I used Google Translate and one guy says: "mainly due to the navigantionBarItem picture and the location of the text caused by the offset".
As I said the view was built in IB with a normal Navigation Controller, no offset in the button. The only difference with other similar viewControllers that work fine is the right navBarButton that is shown in case 1 but not in case 2 with the next code in viewDidLoad:
if (self.fromAppDelegate) {
self.doneButton.title = #"Cerrar";
self.doneButton.enabled = YES;
} else self.doneButton.enabled = NO;
I'm sure its gonna be an easy solution but right now I can't find it. I hope someone can help me.
Update
These are this button's configuration in IB:
InterfaceBuilder: Button
OK, when I was checking the configuration for the button in IB, I noticed that its width (Size Inspector) was zero. I changed it to 80 so, the button shows now in the preview. I also, in Attributes Inspector, changed it from Custom system item to Done and in code added the next line for the else statement:
self.doneButton.title = #"";
It worked, the app didn't crash anymore, but the button, if not enabled, was visible as Done all the time which is not what I want (the code above didn't work because it was set as System Button, duh). So, I change it back to Custom and delete the default title aaaand... everything was as before (check image in the question), but the app still works. What? Well, not everything was as before: the code above was the only change. If I commented the line, the app crashes again.
I don't know if it's a bug or a new requirement, but I hope it useful for someone (I knew the answer was gonna be easy).

I am using YHAnimatedCircleView (http://yickhong-ios.blogspot.it/2012/04/animated-circle-on-mkmapview.html) to display an animated circle on a map. It works well with iOS6, while I am experiencing some problems with iOS7.
The circle appears after a long period on the map and it returns me the following error:

I dont know exactly what your Framework is doing but the drawing of layers shouldn't be done in the main thread. So like in this thread discussed and solved, you should just use an async-dispatcher.
dispatch_async(dispatch_get_main_queue(), ^{
[_mapView addOverlay:circle];
});
Here is an example that updated the YickHong solution for iOS7.
https://github.com/jhurray/iOS7AnimatedMapOverlay
In iOS7, you can no longer add subviews to an MKOverlay. Check out the code here and ping me if you have any questions jeff#energ.io.
I have a storyboard.
In this storyboard there is a UITableViewController that uses a custom class, comMasterViewController.
Using the storyboard, I simply control-drag from the UITableViewController to another scene.
A modal segue is created. I change its identifier to "loadingDataSegue".
In my UITableViewController code, I fire this line:
[self performSegueWithIdentifier:#"loadingDataSegue" sender:nil];
I receive:
Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: 'Receiver (<comMasterViewController: 0x1b6290>) has no segue with
identifier 'loadingDataSegue''
What isn't being hooked up properly?
Thanks for the help
EDIT:
I am pretty sure I am linking the TVC, and not any of the subviews. Looking at the storyboard code, I see the following:
<tableViewController storyboardIdentifier="comMasterViewController"
title="comMasterViewController" clearsSelectionOnViewWillAppear="NO" id="19"
userLabel="comMasterViewController" customClass="comMasterViewController"
sceneMemberID="viewController">
and at the bottom, as a child tag to <tableViewController> and not to any of its subviews:
<connections>
<segue destination="UCh-sM-lba" kind="modal" identifier="loadingDataSegue"
id="epP-jH-GLZ"/>
</connections>

Here is an image:
Make sure you didn't drag that Segue from a TableView Row or UIButton and instead from the VC itself. If you are in doubt, delete the segue and connect it again. Also check for typo's (including case) if that doesn't solve your issue.
I had this exact problem(the symptoms anyway) and ElJay gave me the hint I needed. My problem was caused by the TableViewController being inside a NavigationController and it was opened by an alloc init and push using the NavigationController. This was the reason [self performSegueWithIdentifier] didn't work. Even more, this was also the reason the segue I created from the cell didn't work, so now I don't even need the [self perform...] part, just prepareForSegue and everything works like a charm.
I would have replied this to ElJay, but for some reason I can't. All I could do was give him a vote.
This is a new one. I'm testing that my various viewcontrollers are getting loaded by my tab bar, so I put this on one of them:
- (void)viewDidLoad
{
[super viewDidLoad];
UILabel*yo=[[UILabel alloc] init];
self.testlabel=yo;
self.testlabel.text=[NSString stringWithFormat:#"sup"];
[yo release];
This is what I get when I click the tab button for that controller:
2011-07-26 14:05:37.773 Pickers[802:707] Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key testlabel.'*
What in the world?! I must be doing something exceptionally basic and wrong here. Can anyone spot it?
I've got this in the .h and .m:
#interface SingleVC : UIViewController
#property (nonatomic, retain) IBOutlet UILabel*testlabel;
#end
and
#implementation SingleVC
#synthesize testlabel;
I get the following stack errors (which I do not know how to read):

So after some Googling on other sites, it turns out that quite a few people have had this exact same and basic problem. I found the solution here:
https://discussions.apple.com/thread/1598422?threadID=1598422
I was checking my classes within the individual nibs of each controller, but you must also set the classes in the tab controller as well, for each item (I had already set the nib name for each tab bar item, but not the class).
so, problem resolved and was, as expected, quite basic.
It's a stumper why the error created was for key value coding, though.
perhaps a connection in IB from some object that formerly had an IBOutlet called testlabel?
stop the debugger in ObjC Exceptions and post your stack trace if it's not obvious
Okay, I have a program that I'm trying to test on my iPad. I have it all set up so that the app is able to get on the iPad just fine, but running it on the iPad is a different story.
Now, the thing is, my program was working fine on the debug configuration, but now it won't work on that, either. It's strange, because before I was able to get to a certain part of the program before it crashed, but now it's crashing before that.
The debugger is hardly helping. When I use the debugger window, it will step into one line of code, and then suddenly jump back to another line of code.
I really don't understand what's going on. The crash is now occuring in a root view controller that I have set up, called 'FunctionMachineViewController. Here's the code for when it crashes:
-(IBAction)startOnePlayer:(id)sender
{
GameViewController* GameView = [[GameViewController alloc] initWithNibName:nil bundle:nil];
[GameView isOnePlayer:YES withLevel:startLevelNumber];
[self presentModalViewController:GameView animated:YES];
}
GameViewController is supposed to initialize just fine, but the debugger shows it as uninitialized. I even tried setting it up in the header file instead, but the problem still happens. Has anyone else come across these problems? Any help would be greatly appreciated!
EDIT: Here's what the console says when it crashes:

terminate called after throwing an instance of 'NSException'
Turns out that, when I went and changed the name of several UILabels in the header of GameViewController, I forgot to fix the names in the interface builder, too. Don't know if that was what was causing the debugger to act weird, but everything is working now!
Hey everyone, I'm creating a tab-view application, and in the one tab I have 7 textFields that I am trying to save the information for with a "Save" button. After making the connections between the objects in my controller.h file and the actual text fields, when I select the tab with all this stuff in it, the application crashes and goes to the springboard. I have the debug here:

Program received signal: “SIGABRT”.
Thanks everyone for any help in advance!
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key colour.
In this case check the following:
Ensure that you have not misspelled the key you are trying to access i.e. colour.
The class attribute you are trying to access i.e. colour should be Key Value compliant. You can have the attribute declared as a property in header and synthesize the same in the implementation file. Do not change the default name for the getter and setter in the property declaration. The default method name/signature is KVC compliant.
Apple documentation on KVC covering the accessor method code: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/KeyValueCoding/Articles/Overview.html
If you are using core data ensure that the property being accessed is present in the corresponding header file and also has its code in the implementation file. It can happen that you have added this property later to the model and have not updated the generated header and implementation file.
Came across this post without an answer so thought I would put a response which may help someone else.
