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


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



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 myCustomViewController : UIViewController <UIWebViewDelegate> { {  //...more iboutlets defined above  BOOL *myBoolVariableName; } 

When I compile, I get "error: property 'myBoolVariableName' with 'retain' attribute must be of object type" on the line for the import of my .h file.

I found this page here about an integer / nsnumber:

http://discussions.apple.com/thread.jspa?threadID=1846927

So, it seems I can't use BOOL values inside an @interface definition. What can I use instead?

What should I do for BOOL / boolean values?


How do I detect when the iPhone goes into landscape mode via JavaScript? Is there an event for this?

I'm guessing this later in your interface you have any thing like this:. Having trouble adding objects to NSMutableArray in Objective C
@property (retain) BOOL *myBoolVariableName; 
That means make a property who's value is a pointer to a BOOL, and use retain semantics.. How can I rotate an UIImageView by 20 degrees? Your problem is this BOOL * is a pointer to a byte of memory, not a pointer to an object. Replacing a document body on the iPhoneAnd retain is any thing this applies only to objects.. iPhone App: How to get data from an API, parse, and store for later use? Here's how you must make a BOOL property.. xcode gives syntax error on cpp code
@interface myCustomViewController : UIViewController <UIWebViewDelegate> {     BOOL myBoolVariableName; }  @property myBoolVariableName;  @end 
The important differences are this the variable is declared as "BOOL", not "BOOL *" and the property doesn't have (retain).. Generate Xml

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 although 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..
