How to store UISegmentedControle state in NSUserdefaults

The problem is when de selectedSegmentIndex is unselected: "UISegmentedControlNoSegment" alias "-1".

The other states (0, 1, 2 , etc.), I can store as Integers and retrieve with

carTypeSegmentedControl.selectedSegmentIndex = [defaults integerForKey:@"typeOfCar"];

But -1 is no NSInteger.

I also tried to remove the Integer out of the NSUserdefaults but a request would return an "0", which is not acceptable.

So, is t开发者_StackOverflow社区here another easy way?

-1 is an integer, it's a negative integer. You should be able to store this in NSUserDefaults.

You need to use NSNumber, which is an object representation of values of common numerical and boolean types, e.g. to set:

[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:-1] forKey:kDefaultCarSegmentedControlState];

To retrieve:

NSInteger defaultCarSegmentedControlSelectedIndex = [[[NSUserDefaults standardUserDefaults] objectForKey:kDefaultCarSegmentedControlState] intValue];

You are right Ben, -1 is indead an integer. And it is stored after all. I did an NSLog on that. Stupid i didn't try that. I didn't find clear documentation on that.

So probably my problem is somewhere els.

I guess your answer works as well, Alex.

Thank you for helping
