I have a button in my ProfileView view controller nib called that when pressed I went to display the OptionsView view controller.
In my ProfileView.m file I have this is viewDidLoad:
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Options" style:UIBarButtonItemStylePlain target:self action:#selector(actionOptions)];
and then I have:
- (void)actionOptions
{
OptionsView *screen = [[OptionsView alloc] initWithNibName:#"OptionsView" bundle:Nil];
[self.view addSubview:screen.view];
}
But whenever I tap the button I get a Thread 1: signal SIGABRT with the following console output:
2014-11-24 13:43:54.107 app[2161:5537921] didFailToRegisterForRemoteNotificationsWithError Error Domain=NSCocoaErrorDomain Code=3010 "remote notifications are not supported in the simulator" UserInfo=0x7ff7c2c365d0 {NSLocalizedDescription=remote notifications are not supported in the simulator}

You have SIGABRT because datasource of tableview that displayed in OptionsView is not returning valid cell from tableView:cellForRowAtIndexPath: method.
Code that you are posted is OK.

I am trying to do Peek and Pop in my iOS 9 capable app. The view in question has a UITableView, so I have in my code:
- (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location {
// check if we're not already displaying a preview controller
if ([self.presentedViewController isKindOfClass:[WebViewController class]]) {
return nil;
}
// shallow press: return the preview controller here (peek)
self.webViewController = [[[WebViewController alloc] initWithNibName:#"WebViewController" bundle:[NSBundle mainBundle]] autorelease];
return self.webViewController;
}
- (void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit {
// deep press: bring up the commit view controller (pop)
self.webViewController = [[[WebViewController alloc] initWithNibName:#"WebViewController" bundle:[NSBundle mainBundle]] autorelease];
[self showViewController:self.webViewController sender:self];
}
WebViewController is the ViewController I have already set up to display the content when the row of the tableview is selected. The error I get is:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSCFConstantString stringByAppendingString:]: nil argument'

Your log it's saying exactly what is wrong with your code:
-[__NSCFConstantString stringByAppendingString:]: nil argument'
You are performing stringByAppendingString passing a value that is nil
Also, autorelease is not used anymore if you are using ARC (it's default by now)
Hey when I push another view Controller i get this in my main.m
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
I am using this to push the view controller -
-(void)showMore:(UIButton *)sender
{
MoreViewController *moreViewController = [[MoreViewController alloc] init];
[self.navigationController pushViewController:moreViewController animated:YES];
}
I am sending the message here
[moreButton addTarget:self action:#selector(showSettings:) forControlEvents:UIControlEventTouchUpInside];
Here is my Error -

Does it crash on the first line or the second? Add a breakpoint to each and click the continue button to check which one.
If it's the former there might be some illegal code in your alloc/init for MoreViewController.
If it's the latter, maybe there some class/delegate methods (viewDidLoad, etc) are the culprit.
What is the error message during your crash? (Sometimes clicking the resume-play-button in the debugger in Xcode can reveal a bit more after a crash.)
I didnt find a method named showSettings: in the code you posted. You are pushing your viewController in method named showMore: So I think, the code should be like this:
[moreButton addTarget:self action:#selector(showMore:) forControlEvents:UIControlEventTouchUpInside];
Please check with this.
The error message saying showSettings: method is not found
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSConcreteValue **showSettings:**]: unrecognized selector sent to instance 0x14e5ea70'
And I've notified that you are using showMore: as the name of your method
-(void)showMore:(UIButton *)sender
maybe just change showMore to showSettings, or vice versa
I have a mystery problem with UICollectionView.
I add my collection view to my tableview cell like so:
UICollectionViewFlowLayout *layout = [UICollectionViewFlowLayout new];
layout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
UICollectionView *collection = [[UICollectionView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 100) collectionViewLayout:layout];
[collection setDataSource:self];
[collection setDelegate:self];
[collection setBackgroundColor:[UIColor whiteColor]];
[collection registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:#"Cell"];
collection.tag = kTagPhotoCollectionView;
[cell.contentView addSubview:collection];
I'm implementing all the necessary delegate and data source methods and you can see I've set the datasource and delegate and have implemented them in my header.
When I go and press a UIButton which displays a UIImagePickerController and the app crashes with this error:

libc++abi.dylib: terminating with uncaught exception of type NSException
I have set the datasource, so I have no idea why this would occur.
I faced with the similar problem, but my app crashed after I programmatically pop my UICollectionViewController. In some reason (I think it's just a bug in SDK) self.collectionView was alive after its' controller destroy, thus causing this failure:
*** Assertion failure in -[UICollectionView _createPreparedSupplementaryViewForElementOfKind:atIndexPath:withLayoutAttributes:applyAttributes:], /SourceCache/UIKit/UIKit-2935.137/UICollectionView.m:1305
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UICollectionView dataSource is not set'
The solution is just override -dealloc in UICollectionViewController and release self.collectionView manually. ARC code:
- (void)dealloc {
self.collectionView = nil;
}
Hope this will save time for somebody.
I'm using Action Sheet Picket. I added .h and .m files as instructed in readme, picker and even cancelAction is working well but somehow successAction throws NSInvalidArgumentException with this message: "unrecognized selector sent to instance".
Application is a kind of tab bar application with Navigation Controller. There is a TabBarController as root and there are ViewControllers which are located under the TabBarController and one of the ViewControllers is a Navigation Controller. But I'm not getting this error in Navigation Controller. I'm not sure if this causes any error.
Here how I used:
- (IBAction)filterResult:(id)sender {
[ActionSheetStringPicker showPickerWithTitle:#"Pick Filter" rows:self.filterList initialSelection: self.selectedIndexes target:self successAction:#selector(animalWasSelected:element:) cancelAction:nil origin: self];
}
- (void)animalWasSelected:(NSNumber *)selectedIndex element:(id)element {
self.selectedIndexes = [selectedIndex intValue];
NSLog(#"Selected");
}
Yes that's all. I've already included ActionSheetPicker.h file and as I said picker is working fine.
Finally here is error:
[MYYViewController successAction:]: unrecognized selector sent to instance 0x9032400
2012-12-24 12:14:45.488 Example[54268:11303] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MYYViewController successAction:]: unrecognized selector sent to instance 0x9032400'
Any help would be great.
Looks rather straight forward, you need to implement successAction: in your MYYViewController class, because the picker is not checking if it will respond or not and calling it directly.

The error complains on this line of code:

The error appears only on my iPhone but not on the simulator...
You must uncheck the box in your NIB that says "use auto layout" before you try to run this thing on a device that doesn't support the new NSLayoutConstraint class.
