Question

I need to pass an NSInteger to my Other View Controller:

NSInteger index = [carousel indexOfItemView:sender];

This was implemented in a UIButton, Im thinking of using the NSUserDefaults like this sample code here:

[[NSUserDefaults standardUserDefaults] setObject:4 forKey:@"integer"];
[[NSUserDefaults standardUserDefaults] synchronize];

But I can’t do it with my code above.
Is there other methods.

You can use NSUserdefaults to pass value from one Viewcontroller to another. Use the below code:

NSInteger index = [carousel indexOfItemView:sender];
[[NSUserDefaults standardUserDefaults] setInteger:index forKey:@"integer"];
[[NSUserDefaults standardUserDefaults] synchronize];

You can retrieve it on another view by using the following code:

 NSInteger savedIndex = [[NSUserDefaults standardUserDefaults] integerForKey:@"integer"];
