Question

我不知道标题是否明确，所以我将在这里解释一下。目前我的 UIViewController 和 UIButton 与 IBAction 相关联另一个UIViewController。我想通过让用户向上滑动来避免这一点击，就像拖动另一个UIViewController一样。我找到的所有内容都只是 UIGestureRecognizer ，但我找不到任何控件或任何教程来拖动 UIViewController 。基本上，如果我制定这个儿童方式，我想用一根手指从底部滑动 UIViewcontroller ，并且 UIViewController < / strong>跟着我的手指。谢谢你的帮助！

编辑：我不使用故事板，顺便说一下

导入QuartzCore框架并按照你想要的方式执行此操作，就像在ios7控制中心中一样从底部出现

- (void)viewDidLoad
    {
        upwardView=[[UIView alloc]init];
        upwardView.backgroundColor=[UIColor blueColor];


        UISwipeGestureRecognizer *gesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipe:)];
        gesture.direction = UISwipeGestureRecognizerDirectionUp;
        [self.view addGestureRecognizer:gesture];
        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
    }
    -(void)didSwipe:(UIGestureRecognizer *)gestureRecognizer
    {
        [upwardView setFrame:CGRectMake(0, 265, 320, 230)];
        CATransition *animation = [CATransition animation];
        [animation setType:kCATransitionPush];
        [animation setSubtype:kCATransitionFromTop];
        [animation setDuration:.50];
        [animation setDelegate:self];
        [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
        CALayer *layer = [upwardView layer];
        [layer addAnimation:animation forKey:nil];
        [self.view.window addSubview:upwardView];
    }

如何从另一个向下滑动UIViewController
