从 UIButton 点击​​左侧动画加载 UIView

Question

我在导航栏上有一个 UIButton 作为右栏按钮项。 我想在单击 UIButton 时显示一个视图， 并且该视图应该从右到左显示动画并停止为用户执行一些操作。 当用户完成视图上的工作时，他将单击相同的按钮，视图将从右到左隐藏动画。

我尝试正常加载视图我成功了， 当我应用动画时 视图从右到左动画并消失。 我是这个动画场景的新手。 所以任何人都可以指导我动画视图并在同一个按钮上显示隐藏操作。

这是我尝试过的代码，

-(IBAction)showView :(id)sender
{
    CGRect screen = [[UIScreen mainScreen]applicationFrame];
    UIView *quizInfoViewObj;
    quizInfoViewObj = [[UIView alloc]init];
    quizInfoViewObj.frame = CGRectMake(70, 0, 250, 480);
    quizInfoViewObj.backgroundColor = [UIColor orangeColor];
    [UIView beginAnimations: nil context: NULL];
    [UIView setAnimationDelegate: self];
    [UIView setAnimationDidStopSelector: @selector(pushAnimationDidStop:finished:context:)];
    quizInfoViewObj.center = self.view.center;
    quizInfoViewObj.center = CGPointMake(self.view.center.x - CGRectGetWidth(self.view.frame), self.view.center.y);
    [UIView commitAnimations];

    [self.view addSubview:quizInfoViewObj];
}

这里是我想要的...

此代码可能会对您有所帮助。

   -(IBAction)showView :(id)sender
    {
        UIButton *button = (UIButton *)sender;

        if ([button isSelected] == NO) {

        CGRect screen = [[UIScreen mainScreen]applicationFrame];
        // UIView *quizInfoViewObj; // use this line in .h file variables declaration

        quizInfoViewObj = [[UIView alloc]init];
        quizInfoViewObj.frame = CGRectMake(self.view.frame.width, 0, 250, 480);

        quizInfoViewObj.backgroundColor = [UIColor orangeColor];

        [self.view addSubview:quizInfoViewObj];

        [UIView beginAnimations: nil context: NULL];

        quizInfoViewObj.frame = CGRectMake(70, 0, 250, 480);

        [UIView commitAnimations];

       }
       else {

        [UIView beginAnimations: nil context: NULL];
        [UIView setAnimationDelegate: self];
        [UIView setAnimationDidStopSelector: @selector(pushAnimationDidStop:finished:context:)];
// In pushAnimationDidStop:finished:context method remove quizInfoViewObj from superview

        quizInfoViewObj.frame = CGRectMake(self.view.frame.width, 0, 250, 480);

        [UIView commitAnimations];
       }
    [button setSelected: ![button isSelected]];
}
