Question

In my app I wish to save at some point an “int” value in NSUserDefaults, and it gives me warning about the value not being of an “id” type and being an “int”. i don’t get this warning if I try to insert an NSString.

Here are the details.

The code I have written:

int currentCategoryForUserDefaults = currentCategory; //"cuurentCategory" is an enum value.

NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];

[defaults setObject:currentCategoryForUserDefaults forKey:@"currentCategoryForUserDefaults"];

The warning I get (for the 3rd line):

Semantic Issue : Incompatible integer to pointer conversion sending 'int' to parameter of type 'id'

Anyone?

Answer 1

Use setInteger:forKey: instead of setObject:forKey:. An integer is not an object, it’s a primitive type.

Then, you can retrieve it with integerForKey:.

Another option is to wrap your integer into a NSNumber object.
