Im subclassing CCMenuItemImage with this init method
-(id)initWithChildren:(id)targetedApplication {
if(self = [super initFromNormalImage:#"Answer_Box.png" selectedImage:#"Answer_Box.png" disabledImage:#"Answer_Box.png" target:targetedApplication selector:#selector(answerButtonTapped:)] ) {
NSLog(#"Yes?");
return self;
}
return self;
}
-(void)answerButtonTapped:(id)stuff {
NSLog(#"Answer Button Tapped");
}
and it crashes every time with this error in the console
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSInvocation invocationWithMethodSignature:]: method signature argument cannot be nil'
Thanks in advance for any help.
is -answerButtonTapped a method of targetedApplication? It should be that one. The error says that there is no such a function in target. Or you can pass "self" instead of "targetApplication"

-(void)sliderClicked

[self.window bringSubviewToFront:btntemp];
[self.window bringSubviewToFront:sliderView];
if (sliderView.frame.origin.x==0)
{
btntemp.hidden = YES;
[self performSelector:#selector(presentLeftMenuViewController:)]; // Getting Error in this line
}
else
{
btntemp.hidden = NO;
[self performSelector:#selector(presentLeftMenuViewController:)]; // Getting Error in this line
}
}
above Method is in AppDelegate.m , I am getting error like
+[RESideMenu presentLeftMenuViewController:]: unrecognized selector sent to class 0x10e7902b8
libc++abi.dylib: terminate_handler unexpectedly threw an exception.
RESideMenu classes are from Third party, Method -> presentLeftMenuViewController is from them
will Anybody Please Help me to fix this issue.
I have an UIImageView subclassed as CLImageView that has been implemented with lazy load.
Just ago I have encountered this error message :
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Exercised class for selector implementation needs to be pushed'
*** First throw call stack:
at line : if(self=[super initWithCoder:aDecoder]) {
- (instancetype)initWithCoder:(NSCoder *)aDecoder{
if(self=[super initWithCoder:aDecoder]){
self.placeholderImage = nil;
self.delegate = nil;
self.cacheEnabled = NO;
self.prettyLoad = NO;
}return self;
}
I have never seen this error until 5 years of iOS programming, and I could not find any information on this kind of message here.
If anybody can drop me some ideas would be grateful.
If you need more information just leave a comment or reply.
Thank you so much.
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'

libc++abi.dylib: terminating with uncaught exception of type NSException
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)
Getting crash in CMDActivityViewController for iOS8.
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ArtViewController activityViewController:dataTypeIdentifiersForActivityType:]: unrecognized selector sent to instance 0x7acb0b80'
Solution to this-
In dataTypesForActivityType method of "CMDActivityViewController.m", return nil , instead of the array dataTypes.
Use this Method as it is
- (NSArray *)dataTypesForActivityType:(NSString *)type {
return nil;
}
I'm trying to create this application, when you press on a tablecell you get shown the ViewController, and the variable get's set in the other view controller. Although i'm getting a few errors when i press the uitablecell.

libc++abi.dylib: terminate called throwing an exception
The code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)in dexPath{
NSLog(#"Called");
Aircraft = indexPath.row;
[self performSegueWithIdentifier:#"ToSections" sender:self];
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue.identifier isEqualToString:#"ToSections"]){
AirplaneSections *sections = (AirplaneSections *)segue.destinationViewController;
sections.plane = Aircraft;
}
}
I've found out that it's an error on ViewDidLoad on the viewcontroller.
NSString *quickTemp = [NSString alloc];
switch (plane) {
case 0:
quickTemp = #"Boeing 737-800";
break;
default:
break;
}
TitleLabel.text = quickTemp;
*/
I'm doing something wrong there.
Are you using ARC? This sort of problem usually indicates there's a memory error somewhere. Basically, some code somewhere is trying to access an object that was already released. This makes everything go kaboom.
If you aren't using ARC, you should turn it on.
After that, the next thing you should do is run the static analyzer. Fix anything that comes up.
If that doesn't fix the problem, in Xcode, add a breakpoint that stops when an Objective-C exception is thrown. It should show you where exactly this problem is happening.
If that doesn't help, run your code under Instruments' and the Zombie tool. This will show you exactly where you tried to access memory that was already released.
