Added buttons, webview, added outlets, but can't play with them in the code...
- by Tom
Hi!
I made a toolbar with two buttons on it. I then created two outlets in my class controller. Then I hooked the the controller to the buttons and selected the outlets.
Finally I rewritten the class files (that added:
IBOutlet id next;
IBOutlet id previous;
to my .h file).
So now, everything looks okay. But then I try somewhere in the code to change the state of one of my button like this:
next.enabled = YES;
I tried with self. too but unfortunately I receive this error message:
error: request for member 'enabled' in something not a structure or union
Do you have any idea of what's happening there?
And yes I have:
#import <UIKit/UIKit.h>
:)
Using:
[next setEnabled:YES];
gives me no error but still doesn't work...
And finally, for documenting purposes here's the whole method:
- (void)viewDidLoad {
[super viewDidLoad];
if (!self.currentLevel) {
self.currentLevel = @"1";
}
NSArray *etape = [self.etapes objectForKey:self.currentLevel];
if ([etape count] > 0) {
self.navigationItem.title = [etape objectAtIndex:1];
if ([etape count] > 1) {
[next setEnabled:YES];
}
} else {
self.navigationItem.title = @"Aucune étape";
}
}
When I do:
NSLog(@"%@", [next class]);
It returns (null) ... I guess it is supposed to be UIBarButtonItem...
It seems that it is impossible to play with any outlets even if I don't receive any errors while playing with them...
