Question

Suppose I have an enum as follows:

typedef enum {
    FooGoods = 0,
    FooInsurance = 1,
} FooCategory;

And I have it as property and ivar in another object

@property (nonatomic) FooCategory *category;

When I create that other object, I am filling with values from an NSDictionary So I do something like this:

[baz setCategory:[aDictionary objectForKey:@"Category"]];

However because my enum is not a pointer, I get an error.

Doing this get a warning as well, “Incompatible integer to pointer conversion”:

[baz setCategory:[[aDictionary objectForKey:@"Category"] intValue]];

Any other way that is error/warning free?

Answer 1

The following is not correct

@property (nonatomic) FooCategory *category;

should be changed to

@property (nonatomic) FooCategory category;

Now this should work without warnings

baz.category = (FooCategory)[aDictionary objectForKey:@"Category"] intValue];
