I want to animate a view inside ViewController, somewhat like the notification center as seen on the iPhone.
How does one extend the subview using the x,y and/or the height values to do this? Because I would like it to be compatible with both the 3.5 inch screens and the 4 inch screens, so it would be better not to use specific values.
I just tested this out in my own project and confirmed that it works on varying screen sizes.
UIView *slidingview = [[UIView alloc] initWithFrame:CGRectOffset(self.view.frame, 0, -self.view.frame.size.height)];
slidingview.backgroundColor = [UIColor whiteColor];
[self.view addSubview:slidingview];
[UIView animateWithDuration:1 animations:^{
slidingview.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2);
}];
To implement this, simply replace slidingview
with the view you want to slide down. You would, however, have to declare your own view using the frame I provided.
How about something like this?
CGRect currentFrame = self.view.bounds;
UIView * slidingView = [UIView alloc] initWithFrame:(CGRect){currentFrame.origin, currentFrame.size.width, 0};
[self.view addSubview:slidingView];
[UIView animateWithDuration:0.5f animations:^{
slidingView.frame = currentFrame;
}];
You may need to use delay
version of animateWithDuration...
to make animation in effect.
