Main.m

    int main(int argc, char *argv[])
{
    @autoreleasepool {
        return
        UIApplicationMain
        (argc,
         argv,
         nil,
         NSStringFromClass
         ([AppDelegate class]));
    }
}

The debugger says the error is in the "NSStringFromClass" line. I have no idea what this means or is, please help me! :/

  • The above code is not useful. Put a breakpoint and find exactly where the exception is thrown. Post the crash log. NSRangeException normally occurs when you access an element that is beyond the array limit. – Ramaraj T May 27 '13 at 05:27

As already mentioned, the error is not in the code you have pasted. You can however easily find the code line that contains the error:
In the left column of XCode open the breakpoint navigator. Then click at the bottom left the plus sign. In the context menu that appears, select "Add Exception Breakpoint".
If you now run your code with breakpojnts enabled, the debugger will stop at the line where your error is encountered, and you can easily check e.g. your rnge variables.

Generally NSRangeException occurs when you are using NSArray or NSMutableArray and you want a use a value which is out of range of the array. I don't think there is problem in the the line you mentioned

The doc is here 

- (NSString *)substringToIndex:(NSUInteger)anIndex

here an anIndex value must lie within the bounds of the receiver, or be equal to the length of the receiver.

NSRangeException - that means you've overrun the bounds of an array. The code you have pasted doesn't have any error. When xcode gets any uncaught exception it shows the main.m file, however this doesnt mean that the error is in that file or line.

Check the controller file of the view on which you got this error. Probably you are trying to access an array out of its bounds. For eg. in tableView if you are using any NSArray or NSMutableArray to display content and you return numberOfRowsInSection: more than the total count of that Array then you will get this error.
