Objective-C:
UIWindow *window = [UIApplication sharedApplication].delegate.window;
|
[UIView animateWithDuration:1.0f animations:^{
|
window.alpha = 0;
|
window.frame = CGRectMake(window.bounds.size.width / 2, window.bounds.size.height / 2, 0, 0);
|
} completion:^(BOOL finished) {
|
exit(0);
|
}];
|
Swift:
let window:UIWindow = ((UIApplication.sharedApplication().delegate?.window)!)!
|
UIView.animateWithDuration(1, animations: {
|
window.alpha = 0
|
window.frame = CGRectMake(window.bounds.size.width / 2, window.bounds.size.height / 2, 0, 0)
|
}, completion: {
|
void in exit(0)
|
})
