Question

I know its mad but here it goes:

i load a splashView to my app: on viewDidLoad:

[self.view addSubview:splashView];    

UIViewAnimationOptions options = UIViewAnimationOptionCurveLinear;
[UIView animateWithDuration:0.5 delay:3.0 options:options animations:^{            
    splashView.alpha = 0.0f;
    splashView.frame = CGRectMake(512,384,-10,-10);
}

completion:^(BOOL finished){                          
    [splashView removeFromSuperview]; 
}];

Nothing special to the code here.

however, when i try to load the same view as an action through a button
NOTHING happens:

-(IBAction)showSplash:(id)sender {
    [self.view addSubview:splashView];

    UIViewAnimationOptions options = UIViewAnimationOptionCurveLinear;
    [UIView animateWithDuration:0.5 delay:3.0 options:options animations:^{
        splashView.alpha = 0.0f;
        splashView.frame = CGRectMake(512,384,-10,-10);
    }

    completion:^(BOOL finished){ 
        [splashView removeFromSuperview]; 
    }];
}

why is this happening?

By the way if i DO NOT load the splashView on the viewDidLoad and then use the button (action) it works ok!

is this normal behavior?

Answer 1

Reset the alpha value before fading the splash view out.

splashView.alpha = 1.0f;
