UIButton setting hidden

[ebeth18]

I am working on an app for the iPad and I have a UIButton in the detail view.

in DetailViewController.h:

IBOutlet UIButton *myButton

in DetailViewController.m:

-(void)setDetailItem:(id)newDetailItem{
  if (detailItem != newDetailItem){
     [detailItem release];
     detailItem = [newDetailItem retain];
  }
  myButton.hidden = NO;
  if (self.popoverController != nil){
     [self.popoverController dismissPopoverAnimated:YES];
  }
}

-(void) viewDidLoad{
myButton.hidden = YES;
[super viewDidLoad]; //also, what does this mean?
}

I am not sure why the button refuses to unhide. I have it set to enabled and hidden in Interface Builder, and am trying to figure out why it's not becoming visible when I change the value of myButton.hidden. Thoughts?

Double check your button connection.

[super viewDidLoad] will call viewDidLoad on your super class. If you are using the default UIViewController subclass, calling viewDidLoad on super won't really do anything but it's good practice. On stuff like viewDidLoad, call super first.

Why did you set it to hidden in IB? Try not to...

Must be your IB to code connection that is broken. setting myButton.hidden = NO should work fine. Try adding this line to viewDidLoad:

NSLog(@"button %@", myButton);

It probably thinks it is nil.
