0、类似实现dropdownmunu类型的动画)

-(void)chooseClick:(UIButton *)btn{
    btn.selected = !btn.selected;
    if (btn.selected) {
        [UIView animateWithDuration:0.25 animations:^{
            btn.imageView.transform = CGAffineTransformRotate(btn.transform, M_PI);
        }];
        UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 64, self.view.bounds.size.width, 0)];
        [self.view addSubview:view];
        PopView *popView = [PopView popSideContentView:self.chooseListView belowView:view];
        popView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.2];
        [popView setDidRemovedFromeSuperView:^{
            btn.selected = NO;
            [UIView animateWithDuration:0.25 animations:^{
                btn.imageView.transform = CGAffineTransformIdentity;
            }];
        }];
        [view removeFromSuperview];
    }else{
        [UIView animateWithDuration:0.25 animations:^{
            btn.imageView.transform = CGAffineTransformIdentity;
            }];
            [PopView hidenPopView];
    }
}

1、类似QQ和微信消息页面的右上角微型菜单弹窗

PopView *popView = [PopView showPopViewDirect:PopViewDirection_Bottom onView:sender contentView:self.popContentView];
popView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.3];

2、侧边栏(处理了键盘遮挡的问题)

PopView *popView = [PopView showSidePopDirect:PopViewDirection_SlideFromUp contentView:self.qzoneView];
popView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.3];

3、自定义显示和隐藏动画

CABasicAnimation *showAnima = [CABasicAnimation animationWithKeyPath:@"transform"];
showAnima.duration = 0.25;
showAnima.fillMode = kCAFillModeForwards;
showAnima.removedOnCompletion = YES;
CATransform3D tofrom = CATransform3DMakeScale(1, 1, 1);
CATransform3D from = CATransform3DMakeScale(0, 0, 1);
showAnima.fromValue = [NSValue valueWithCATransform3D:from];
showAnima.toValue =  [NSValue valueWithCATransform3D:tofrom];

CABasicAnimation *hidenAnima = [CABasicAnimation animationWithKeyPath:@"transform"];
hidenAnima.duration = 0.25;
hidenAnima.fillMode = kCAFillModeForwards;
CATransform3D tofrom1 = CATransform3DMakeScale(1, 0, 1);
CATransform3D from1 = CATransform3DMakeScale(1, 1, 1);
hidenAnima.fromValue = [NSValue valueWithCATransform3D:from1];
hidenAnima.toValue =  [NSValue valueWithCATransform3D:tofrom1];

self.loginView.center = self.view.center;
self.loginView.backgroundColor = [UIColor whiteColor];
PopView *popView = [PopView showPopContentView:self.loginView showAnimation:showAnima hidenAnimation:hidenAnima];
popView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.3];
popView.clickOutHidden = NO;
