ios - 打开/关闭 View 作为菜单

Question

我正在尝试执行打开和关闭 View (菜单)的效果，该 View 的原点为x = 55。打开效果正常效果不错，但是关闭效果有问题:效果从 x = 0 开始，而我的 View 在 x = 55...然后效果看起来很奇怪...

这是我的代码:

    -(IBAction)menuClick:(id)sender {
    if(!self.viewMais) {
        CGRect screen = [[UIScreen mainScreen]bounds];
        self.viewMais = [[UIView alloc]initWithFrame:CGRectMake(55, 0, screen.size.width-55, screen.size.height)];
        [self.viewMais setBackgroundColor:[UIColor blackColor]];
        [self.view addSubview:self.viewMais];
        [self open];
    }
    else {
        [self close];
    }

}

    -(void)open {
    CATransition *transition = [CATransition animation];
    transition.duration = 0.3;
    transition.timingFunction =
    [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionMoveIn;
    transition.subtype = kCATransitionFromRight;
    UIView *containerView = self.viewMais;
    [containerView.layer addAnimation:transition forKey:nil];
}

-(void)close {
    CATransition *transition = [CATransition animation];
    transition.duration = 0.3;
    transition.timingFunction =
    [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionMoveIn;
    transition.subtype = kCATransitionFromLeft;
    UIView *containerView = self.viewMais;
    [containerView.layer addAnimation:transition forKey:nil];
    [self performSelector:@selector(removerViewMais) withObject:nil afterDelay:0.3];
}

-(void) removerViewMais {
    [self.viewMais removeFromSuperview];
    self.viewMais = nil;
}

-(IBAction)showPicker{

if (!isPickerShow) {

    [self.view endEditing:YES];
        [UIView animateWithDuration:0.3 animations:^{

            viewWithPicker.frame = CGRectMake(0, [UIScreen mainScreen].bounds.size.height-viewWithPicker.frame.size.height, 320, 555);
            isPickerShow=YES;
        }];

}

-(IBAction)隐藏选择器{

if (isPickerShow) {

    [UIView animateWithDuration:0.3 animations:^{

            viewWithPicker.frame = CGRectMake(0, [UIScreen mainScreen].bounds.size.height , 320, 255);

            isPickerShow=NO;


    }];
