Hi,
- (void) setValue: (id) value forKey: (NSString*) key; takes an
object for it's first param. The documentation is referring to the
fact that you can *bind* that key to the intValue of some other
object. But the automatic wrapping won't take place when you're
calling it directly as you are in this code.
Hope that helps,
Guu

Hi
I read the key-value coding documentation and it specifically
states that you should be able to set values without having to
first pack them into an object
"Key-value coding supports properties that are objects, as well as
the scalar data types and structures that are supported by NSNumber
and NSValue. Non-object parameters and return types are detected
and automatically wrapped, and unwrapped, as required."
So how come when I go to compile my project with setValue:forKey: I
get " error: invalid conversion from 'int16' to 'objc_object*'"
For example:
@interface Foo : NSObject
{
int bobo;
}
@end
@implementation Foo
- (id) initFoo
{
self = [super init];
if (self)
{
[self setValue: 10
forKey: @"bobo"];
}
return self;
}
@end
What am I messing up here?
Thanks for any help
Ken
