IOS: fatal exception: NSRangeException

Question

The application works fine before updating iOS 11. After deploying iOS 11, some users get it lower, but I can’t reproduce it in the iOS 11 simulator. Based on fabric.io, not all iOS 11 experience this, so far I have received only 22 reports crashes from 4 users. Need help here, thanks.

Fatal Exception: NSRangeException

Not a complete solution, but if he tries to delete an object at index 9223372036854775807, it is worth noting that this is not a random number, but the maximum value of a 64-bit integer may contain

self.inputDatePicker = [[DatePickerView alloc] init...];
self.inputDatePicker.calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian]
self.inputDatePicker.datePicker.datePickerMode = UIDatePickerModeDate;

if (self.inputDatePicker == nil) {
    // do something or perhaps better to check you nib
}

FirstObject.

You have the opportunity to check the contents nib. Does it contain the requested view or is it empty? If an empty name check your xib file. I personally prefer to write the xib name in something like NSStringFromClass([self class])- because it requires the same name for the class file and xib, but less error prone.

Answer 4

You have the wrong setup view from nib. You can use my library or see the code on how to add components from xib.

RMNibLoadedView

Answer 5

Maybe you assigned 2 collectors for the same property?

self.inputDatePicker = [[DatePickerView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 260)];
self.inputDatePicker = [nib objectAtIndex:0];

It should look like:

self.inputDatePicker = [nib objectAtIndex:0];
self.inputDatePicker.frame = CGRectMake(0, 0, self.view.frame.size.width, 260);
