Question

When I set an xib class to a sub class of UIView and then animateWithDuration on the UIView I get

No visible @interface for 'UIView' declares the selector
'animateWithDuration:delay:options:animations:completion:' 

The error pane shows it is an ARC issue

I am trying to run an animation on the UIView.

EDIT: The code causing error

 [sampleSourceView.view animateWithDuration:1
                                             delay:1.0
                                           options: UIViewAnimationCurveEaseOut
                                        animations:^{
                                            sampleSourceView.view.frame = sampleSourceFrame;
                                        } 
                                        completion:^(BOOL finished){
                                            NSLog(@"Done!");
                                        }];

        [self.view addSubview:sampleSourceView.view];

You are getting the error because you are trying to use a class method on an instance of UIView. Check out the method signature:

+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion

The plus sign indicates it is a class method. An instance method would have a minus sign.

Try this:

[UIView animateWithDuration:1
                     delay:1.0
                   options: UIViewAnimationCurveEaseOut
                animations:^{
                    sampleSourceView.view.frame = sampleSourceFrame;
                } 
                completion:^(BOOL finished){
                    NSLog(@"Done!");
                }];
