How are you accessing your custom view's object value? It almost
sounds like you're asking your original custom view for it's value
each time instead of the object currently being displayed.
When you create your template and insert your custom view, make sure
to keep a reference to that specific object so you can query it later
on.
@interface CustomPredicateEditorRowTemplate : NSPredicateEditorRowTemplate
{
CustomTextField *myTextField;
}
-(CustomTextField *) myTextField;
@end
@implementation CustomPredicateEditorRowTemplate
-(CustomTextField *) myTextField
{
if( !myTextField )
// init your view
return( myTextField );
}
- (NSArray *)templateViews
{
return( [[super templateViews] arrayByAddingObject:[self myTextField]] );
}
-(void) dealloc
{
[myTextField release];
[super dealloc];
}
- (NSPredicate *)predicateWithSubpredicates:(NSArray *)subpredicates
{
id objectValue = [[self myTextField] objectValue];
// Do magical things with objectValue
}
@end
