I have a very difficult problem when I launched my app on IOS10.3.3.. Indeed, I got this error in my splashviewController :
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
// [[EMAnalyticsManager sharedInstance]sendScreenViewWithName:SplashScreen];
}
I got this crash message:
[__NSCFString nsli_lowerAttribute:intoExpression:withCoefficient:forConstraint:]: unrecognized selector sent to instance 0x165e3630
2018-09-06 16:57:31.456059+0100 **********[2461:1072580] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString nsli_lowerAttribute:intoExpression:withCoefficient:forConstraint:]: unrecognized selector sent to instance 0x165e3630'
I made many research to understand the cause of this crash that didn't occur in IOS11.
Any help please??
Some constraints might be causing this when the very first view controller is loaded. Please check your constraint and you can also remove the constraints and then verify if it works.

After testing my app in a iOS 7 device, I got a crash calling containsString from NSString, and then I realised that that methods has NS_AVAILABLE(10_10, 8_0);
Is there anyway to check automatically my program to see if there is any other method that is not available in iOS 7?
How is possible to compile and app with deployment target of 7.0 and not saying any warning or error in these cases?

You should use rangeOfString instead of containsString. Since rangeOfString available from iOS 2.0, you will not get crash on this.
Code snippets,
NSString *string = #"https://www.google.co.in/";
NSString *substring = #"http";
if ([oneContent rangeOfString:subString].location == NSNotFound) {
NSLog(#"string does not contain substring");
} else {
NSLog(#"string contains substring!");
}
Otherwise you can add category class for NSString and have a method like containsString: where you can implement the above code. It'll work dynamically.
As the name states I am working with UITableView and CoreData. I have a custom UITableViewCell which has title and detail label. In my cellForRowAtIndexPath it crashes. I have found the issue I was passing NULL but the issue is it doesn't crash at
cell.detailLabel.text = [[factors valueForKey:#"factorsdescription"] lastObject];
but after many times cellForRowAtIndexPath is called and even on that cell in which I'm not passing null. any ideas?

I am trying to use KTPhotoBrowser to use its thumbnail view capabilities. I have some difficulties to push to the viewController that was derived from KTThumbsViewController. It seems the navigationController can only push to UIViewController:
- (void)showSDWebImageSample
{
KTThumbsViewController *newController = [[KTThumbsViewController alloc] init];
[self.navigationController pushViewController:newController animated:YES];
}
and the header file for KTThumbsViewController includes:
#interface KTThumbsViewController : UIViewController <KTThumbsViewDataSource>
I grabbed the code from the provided sample. But it gives me the following runtime error:
-[KTThumbsViewController copyWithZone:]: unrecognized selector sent to instance 0x8877130
2012-10-30 14:52:03.004 myCases_MD[36941:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[KTThumbsViewController copyWithZone:]: unrecognized selector sent to instance 0x8877130'
Could anyone help me please?
Cheers,
I want to load another xib, and use this simple code:
AddElementViewController *viewToLoad = [[AddElementViewController alloc] initWithNibName:#"AddElementViewController" bundle:nil];
viewToLoad.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:viewToLoad animated:YES];
for some reason it throws me out with this output:

do you have any idea what can cause it?
Somewhere in your code (it seems to be in AddElementViewController implementation) you are sending message AddPressed: to object of class MainViewController.
The call stack and crash error says that there are no method AddPressed: in class MainViewController.
Try to find all places where you are calling AddPressed: (first of all check loadView, viewDidLoad, viewWillAppear, viewDidAppear, init of AddElementViewController class) and check the type of receiver.
I have a button within interface builder that has a '0' tag on it. The button has a method linked to it called -(IBAction) doTest:(id)sender.
I have the doTest method within my .m file as shown below:
-(IBAction) doTest:(id)sender
{
int currentSelection= [sender tag];
if (currentSelection == 0)
{
// do something
}
}
However my app crashes with the following error message and I have no idea why. Any help would be appreciated. Thanks.
