Question

我正在为iPhone制作应用程序，我希望当我触摸按钮时，当您从屏幕的顶部触摸到底部时，它会打开一个带有幻灯片效果的视图。视图与按钮位于同一个XIB文件中...提前谢谢

Answer 1

您可以尝试这个简单的动画 -

UIView *myView = [[UIView alloc] initWithFrame:self.view.frame];
myView.backgroundColor = [UIColor blueColor];
[self.view addSubview:myView];

[myView setFrame:CGRectMake(0, 480, 320, 480)];
[myView setBounds:CGRectMake(0, 0, 320, 480)];

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
[UIView setAnimationDelegate:self];
[myView setFrame:CGRectMake(0, 0, 320, 480)];
[UIView commitAnimations];

您需要使用GestureRecognizer

简单地使用下面的代码

- (void)viewDidLoad
{

    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.5];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.view layer] addAnimation:animation forKey:kAnimationKey];

    UISwipeGestureRecognizer *swipeGesture = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(addCustomBottomBar)] autorelease];
    swipeGesture.numberOfTouchesRequired = 1;
    swipeGesture.direction = (UISwipeGestureRecognizerDirectionDown);
    [yourDownViewController.view addGestureRecognizer:swipeGesture];
    UISwipeGestureRecognizer *swipeGestureTop = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(addCustomBottomBar)] autorelease];
    swipeGestureTop.numberOfTouchesRequired = 1;
    swipeGestureTop.direction = (UISwipeGestureRecognizerDirectionUp);
    [yourUpViewController.view addGestureRecognizer:swipeGestureTop];
 }

这里你只需在addCustomBottomBar方法中设置这个viewcontroller的框架就像下面那样......

-(void)addCustomBottomBar{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.window cache:YES];


    yourUpViewController.view.frame=CGRectMake(0, 430, 320, 70);//here you can also switch two ViewWith some flag otherwise create another method for anotherView....

    [UIView commitAnimations];
}

2.如果你想使用带按钮的ViewController进行动画点击然后使用下面的代码.....

-(void)btnClicked{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.view cache:YES];

    if (yourflag) {

       yourViewController.view.frame=CGRectMake(0, 430, 320, 70);
    }
    else{
        yourflag=YES;
        yourViewController.view.frame=CGRectMake(0, 210, 320, 270);
        [self.view bringSubviewToFront:yourViewController.view];
    }
    [UIView commitAnimations];
}

希望，这有助于你...... ：）
