error: property 'myBoolVariableName' with 'retain' attribute must be of object type

Question

I have a BOOL value inside my @interface definition in my .h file. Here it is below. It has the same problem whether it\'s a pointer or not.

@interface myCusto         


        

Answer 1

I'm guessing that later in your interface you have something like this:

@property (retain) BOOL *myBoolVariableName;

That means make a property who's value is a pointer to a BOOL, and use retain semantics.

Your problem is that BOOL * is a pointer to a byte of memory, not a pointer to an object. And retain is something that applies only to objects.

Here's how you can make a BOOL property.

@interface myCustomViewController : UIViewController <UIWebViewDelegate> {
    BOOL myBoolVariableName;
}

@property myBoolVariableName;

@end

The important differences are that the variable is declared as "BOOL", not "BOOL *" and the property doesn't have (retain).

Answer 2

I have faced similar situation. I solved it like,

@interface myCustomViewController : UIViewController {
BOOL myBoolVariableName;
}
@property BOOL myBoolVariableName;
@end

I refer one answer by Jon Hess but I got one error in it. Type name requires a specifier or qualifier. My previous version was like,

@property myBoolVariableName;

So I added BOOL and solved the issue.
