I would like to present a view in the same manner as that of UIAlertView - a pop/spring. Unfortunately subclassing UIAlertView is not an option for the view I need to present. I have written some code, but I can't seem to get it as realistic as I would like. I would appreciate any suggestions for greater realism or a link if anything similar has been done (I could not find anything on Google). Thank you.
- (id)initWithFrame:(CGRect)frame {
if ((self = [super initWithFrame:frame])) {
self.backgroundColor = [UIColor whiteColor];
v = [[UIView alloc] initWithFrame:CGRectMake(140, 140, 60, 60)];
v.backgroundColor = [UIColor blueColor];
[self addSubview:v];
[self animate];
}
return self;
}
- (void)animate {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:0.2];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(popStep1Complete)];
v.frame = CGRectMake(90, 90, 140, 140);
[UIView commitAnimations];
}
- (void)popStep1Complete {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:0.15];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(popStep2Complete)];
v.frame = CGRectMake(110, 110, 100, 100);
[UIView commitAnimations];
}
- (void)popStep2Complete {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:0.15];
v.frame = CGRectMake(100, 100, 120, 120);
[UIView commitAnimations];
}
