iOS：对View添加动画的常用方法

-(void) showOrHiddenMenuAndButtomView{

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.25];
//        [UIView setAnimationDelay:0.5];
[UIView setAnimationDelegate:self];
//    [UIView setAnimationDidStopSelector:@selector(showMenuStop)];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

if (ismenuViewShow) {
ismenuViewShow = NO;
//        menuView.hidden = YES;
//        butttomView.hidden = YES;
menuView.frame = CGRectMake(0, -60, 1024, 60);
butttomView.frame = CGRectMake(0, 748, 1024, 40);
} else {
ismenuViewShow = YES;
//        menuView.hidden = NO;
//        butttomView.hidden = NO;
menuView.frame = CGRectMake(0, 0, 1024, 60);
butttomView.frame = CGRectMake(0, 708, 1024, 40);
}

[UIView commitAnimations];
