The question explains it all actually.
I load a custom UIView on top of my current view, animated, using this code:
- (void)showView
{
self.blurView.alpha = 0.f;
[UIView animateWithDuration:2.0 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction animations:^
{
self.blurView.alpha = 1.f;
} completion:^(BOOL finished) {
[UIView animateWithDuration:2.0 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction animations:^
{
self.blurView.alpha = 0.f;
} completion:nil];
}];
}
It works, but when I perform -(void)showView again while it is still animating, the custom view doesn't get removed from the screen.
It just stays like this:
I figured out what the problem was.
blurView
is a public variable and every time I did -(void)showView
it used the same variable, setting the alpha to 0.f just once, thus never changing the alpha of the first show.
I declared the variable blurView
in the method itself and now it works because every blurView
gets it's own pointer.
-(void)someMethod
{
//Create a live blur view
FXBlurView *blurView = [[FXBlurView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
blurView.center = CGPointMake(self.view.window.frame.size.width / 2, self.view.window.frame.size.height / 2);
blurView.layer.cornerRadius = 20.f;
[self.view.window addSubview:blurView];
[self showView:(blurView)];
}
- (void)showView:(FXBlurView *)blurView
{
//Make full transparent before showing
blurView.alpha = 0.f;
//Start animation
[FXBlurView animateWithDuration:1.0 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction animations:^
{
blurView.alpha = 1.f;
} completion:^(BOOL finished) {
if (finished)
{
//End animation
[FXBlurView animateWithDuration:1.0 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction animations:^
{
blurView.alpha = 0.f;
} completion:nil];
}
}];
}
You should add to the top of your function this line:
[self.view.layer removeAllAnimations];
It will remove all of the active animations.
It doesn't work because you have implemented a delay, use animation block with delay - it will create animation keys that could be removed with this function above.
[UIView animateWithDuration:0.3 delay:0.0
options:UIViewAnimationOptionAllowUserInteraction
animations:^
{
// ...
} completion:NULL];
