Question

我有一个问题（与Objective-C相关）。

我想通过单击注释在根映射视图控制器顶部创建从底部ViewController滑动。

1）点击注释后，它应从底部滑动并显示10％的高度;
2）向上滑动手势后 - 如果用户将其完全向上拖动，它应显示高达100％;
3）在向下手势上，用户应该能够将其可见高度再次降低到10％;
4）在MapView上单击底部的ViewController应该隐藏。

我包括流程实施的可视化方案。

非常感谢任何想法！

您始终可以尝试编写自己的segue动画以在ViewControllers之间进行切换。只需创建一个自定义的UIStoryboardSegue，并覆盖其perform方法。以下是一段摘录：

@interface HorizontalSegue : UIStoryboardSegue

@property CGPoint originatingPoint;

@end


@implementation VerticalSegue

- (void)perform {
    UIViewController *sourceViewController = self.sourceViewController;
    UIViewController *destinationViewController = self.destinationViewController;

    NSArray* windowArray = [UIApplication sharedApplication].windows;
    if (windowArray.count > 0) {
        UIWindow* appWindow = [windowArray lastObject];
        [appWindow insertSubview:destinationViewController.view aboveSubview:sourceViewController.view];
    }
    else
        [sourceViewController.view addSubview:destinationViewController.view];

    // Store original centre point of the destination view
    CGPoint originalCenter = destinationViewController.view.center;

    // Set center to start point of the button
    destinationViewController.view.center = CGPointMake(self.originatingPoint.x, self.originatingPoint.y*3);

    [UIView animateWithDuration:0.25
                          delay:0.0
                        options:UIViewAnimationOptionCurveEaseInOut
                     animations:^{
                         destinationViewController.view.center = originalCenter;
                     }
                     completion:^(BOOL finished){
                         [sourceViewController presentViewController:destinationViewController animated:NO completion:NULL]; // present VC
                     }];
}

@end

使用此功能，您可以轻松制作自定义动画。我不完全确定将ViewController添加到窗口的部分是否正确，但您可以尝试自行检查/纠正。

动画segues的另一种方法是使用CATransition：

-(void)perform
{
    UIViewController *sourceViewController = (UIViewController*)[self sourceViewController];
    UIViewController *destinationController = (UIViewController*)[self destinationViewController];

    CATransition* transition = [CATransition animation];
    transition.duration = 0.25;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionMoveIn; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
    transition.subtype = kCATransitionFromLeft; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom

    [destinationController.view.layer addAnimation:transition forKey:kCATransition];
    [sourceViewController presentViewController:destinationController animated:NO completion:nil];
}

使用手势从底部滑动视图控制器
