I just moved to iOS 8, installed Xcode 6 etc.
This code worked nicely on iOS 7 and 6. It even seems to work on an iPhone 4S with iOS 8 installed. But on iPhones 5 and 5S it crashes. (8.0.0 and 8.0.2 alike)
It does not matter whether the app is build against SDK 7 or 8. It crashes in both cases at the same stage.
The .h file contains:
#property (nonatomic, strong) NSMutableArray* filterBrandsExclude;
from the .m file:
// Following lines just to set the conditions for your understanding:
_filterBrandsExclude = [[NSMutableArray alloc] initWithCapacity:0]; // just creates an empty array.
// As a matter of fact, this array may well be empty and it worked nicely on older iOS versions.
// this line crashes:
[userDefaults setObject:_filterBrandsExclude forKey:#"filterBrandsExclude"];
Error Message:
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSKeyValueSlowMutableArray getObjects:range:]: value for key filterBrandsExclude of object 0x17004ae00 is nil'

Any idea is appreciated.
you can manually check
if(self.filterBrandsExclude != nil && self.filterBrandsExclude.count > 0)
[userDefaults setObject:_filterBrandsExclude forKey:#"filterBrandsExclude"];
else
[[NSUserDefaults standardUserDefaults] removeObjectForKey:#"filterBrandsExclude"];
Two things.
In your error it says that the value for the key filterBrandsInclude is nil, but in your question you reference the key filterBrandsExclude. Are you sure you've pinpointed the actual error at this point?
EDIT: Point #2 is invalid.

This line of code crashes. How to check if tabor item is not nil then setting badge?
[self.tabController.tabBar.items objectAtIndex:0].badgeValue = [NSString stringWithFormat:#"%i", num];
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[_CTNativeGlyphStorage
tabBar]: unrecognized selector sent to instance 0x15029cfd0'
I checked it by this line of code, but it didn't solve the problem.
if (self.tabController.tabBar.items != nil) { }
If you are setting the badge value before the tab controller is even presented or fully initiated, then there wont be anything at index 0 as yet. There is no need for the tab controller to initiate everything until time comes for presentation, for memory usage purposes. You can keep a reference to each instance of UITabBarItem and set the badge value on them. Or you are going to have to wait until viewDidAppear is called, ensuring all UITabBarItems are fully instantiated...
I cant assume anything else here without seeing the rest of your code.
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.
I have a iPad app (XCode 6.1.1, iOS 8.1, ARC) that when I run it on the 8.1 simulator, the app crashes comparing the length of a string. This has been running for over a year, and stopped yesterday. This is the code:
This is the code in the .h file:
#property NSString *shopOpenHour;
#property NSString *shopCloseHour;
This is the code in the .m file:
#synthesize shopOpenHour;
#synthesize shopCloseHour;
and:
if(shopOpenHour.length == 0 || shopCloseHour.length == 0) {
and this also causes a crash:
NSLog(#"\n\nlength test: %d", (int)shopCloseHour.length);
This is the error I'm getting:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0xb000000000003203'
It runs fine when running under a 7.1 simulator and a iPad running iOS 8.1. I don't understand where/why NSCFNumber is "in the picture".
My question is: any ideas of what's causing this (before I submit a RADAR?)
Somewhere you have assigned a NSNumber to shopCloseHour, it can happen when assigning value from json .Check
if ([shopCloseHour isKindOfClass:[NSString class]]) {
// this is a string …
}
I have an iOS App that I just submitted an update for. The development version of the app (simulator and my 4S) never crashed and it works just fine. The app got approved today as well as the IAP, but I realized this morning that the iAP was not "cleared for purchase". I just cleared it for purchase, but the app still crashes. The error the iPhone gives (running the app store version) gives the error:
<Error>: *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array'
Here is the code where that happens:
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:
(SKProductsResponse *)response
{
NSArray *myProduct = response.products;
//this line is where the error occurs
noAdProduct = [myProduct objectAtIndex:0];
if (![[[NSUserDefaults standardUserDefaults] objectForKey:#"the id here"] boolValue]) {
adCell.detailTextLabel.text = [NSString stringWithFormat:#"$%#", noAdProduct.price];
adCell.userInteractionEnabled = YES;
adCell.accessoryType = UITableViewCellAccessoryNone;
adCell.accessoryView = nil;
[self.tableView reloadData];
}
}
This happens while requesting a list of available products, which obviously returns the product in the simulator but not in the app. I just added a safeguard against this but I will need to submit it to the App Store again.
Does anyone know why the iAP is not showing up for the App Store version? Do I need to wait for the "cleared for sale" option to go to Apple's servers? Thanks!
Obviously myProduct array is empty. Why this happens is another question, but you should never call objectAtIndex without making sure the requested index exists.
if ([myProduct count] > 0)
noAdProduct = [myProduct objectAtIndex:0];
else
// Deal with the situation when the array is empty.
I just began to work with Objective-C and I'm managing pretty well. My last challenge was to make a command line utility, which I could than use in AppleScript. But my code does not work, not in the terminal, not in the AppleScript. So I'm asking you, what's the error in this peace of code, that should be very plain and easy?
int main(int argc, char *argv[]) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
// -imagePath
// -filePath
NSUserDefaults *args = [NSUserDefaults standardUserDefaults];
NSString *soundPath = [args stringForKey:#"imagePath"];
NSString *filePath = [args stringForKey:#"filePath"];
BOOL worked = [[NSWorkspace sharedWorkspace] setIcon:[[NSImage alloc] initWithContentsOfFile:soundPath] forFile:filePath options:0];
NSLog(#"Worked: %i",worked);
[pool release];
return 0;
}

In effect, that means “You can't do that in a command-line tool”. If you run your tool in the debugger, it'll tell you what “that” is in the stack trace. My guess is that “that” is creating the NSImage.
Another solution is to rewrite the tool to use Icon Services instead of NSWorkspace. The APIs you'll need are still available and not deprecated.

One solution is to rewrite it as an application. Perhaps a document-based one, with an image view in the document window, set up to receive dragged images and files.
I have an application that uses basically that code to set icons on OS X:

I'm not sure why yours isn't working.
