Question

I’ve got a very simple project that tries to animate a UIView using block based iOS4.0 animation.

header

@interface animatepadViewController : UIViewController {

    UIView *contentView;
}

@property(nonatomic, retain) IBOutlet UIView *contentView;



@end

implementation

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];

    [UIView animateWithDuration:1.0 animations:^{self.contentView.alpha = 0.0;}];

}

I’ve added a subview of type UIVIew in the interface builder with a background color of black.

these are the only change i’ve made from the default ipad “view” based project.

I get the following error

2010-12-28 17:59:05.689 animatepad[29835:207] *** +[UIView animateWithDuration:animations:]: unrecognized selector sent to class 0x217689c

this happens only on the ipad and NOT on the iPhone

thanks in advance

To update the simulator, you will need to update Xcode to version 3.2.5.
