我正在玩弄新的 UIViewControllerContextTransitioning
在 UViewController
之间里面UINavigationViewController
我所拥有的和我想要实现的很简单,但我在某处失败了
我有一个 MKMapView
(300px * 60px) 在 UIScrollView
内.通过单击该 map (无论它在可见滚动条的哪个位置),我想转到下一个包含全尺寸 MKMapView
的 View 。 .
我想要的感觉和动画是让用户感觉到他们被吸入 map (有点)=)
到目前为止我已经添加了:
<UIViewControllerTransitioningDelegate, UINavigationControllerDelegate>
和
-(id<UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController animationControllerForOperation:(UINavigationControllerOperation)operation fromViewController:(UIViewController *)fromVC toViewController:(UIViewController *)toVC{
if (operation == UINavigationControllerOperationPush) {
NSLog(@"inside itself");
FixRTransitionAnimator *animator = [FixRTransitionAnimator new];
animator.presenting = YES;
CGRect absoluteframe = [self.mainScrollView convertRect:self.mapView.frame toView:self.view];
animator.mapFrame = absoluteframe;
NSLog(@"the map frame is %@", NSStringFromCGRect(self.mapView.frame));
return animator;
}
else
NSLog(@"nope its outside");
return nil;
}
然后到 prepareForSegue
我有的方法:
[super prepareForSegue:sender sender:sender];
MapViewController *mapViewController = segue.destinationViewController;
mapViewController.transitioningDelegate = self;
mapViewController.modalPresentationStyle = UIModalPresentationCustom;
最后我有了 `FixRTransitionAnimator.m``
-(NSTimeInterval)transitionDuration:(id<UIViewControllerContextTransitioning>)transitionContext{
NSLog(@"the time is timed");
return 0.5f;
}
-(void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext{
NSLog(@"we are inside %@",NSStringFromCGRect(self.mapFrame));
UIViewController *fromVController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
UIViewController *toVController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
CGRect endFrame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width,[UIScreen mainScreen].bounds.size.height);
if (self.presenting) {
fromVController.view.userInteractionEnabled = NO;
[[transitionContext containerView]addSubview:fromVController.view];
[[transitionContext containerView]addSubview:toVController.view];
toVController.view.frame = self.mapFrame;
[UIView animateWithDuration:[self transitionDuration:transitionContext] animations:^{
fromVController.view.tintAdjustmentMode = UIViewTintAdjustmentModeDimmed;
NSLog(@"inside the animation");
toVController.view.frame = endFrame;
} completion:^(BOOL finished) {
[transitionContext completeTransition:YES];
}];
}else{
...
}
}
过渡动画在 destinationViewController 为空的情况下效果很好。但是动画中的 map 真的很奇怪,完全不像我想要的那样。
任何人对我错过或需要想到的事情有任何指示吗?
最佳答案
我在另一个answer写了一个帖子,但请确保您正在设置 UINavigationControllerDelegate。
presented Controller 有一个 UIViewControllerTransitioningDelegate
,pushed Controller 有一个 UINavigationControllerDelegate
。协议(protocol)中的委托(delegate)方法返回您的动画师。
关于Ios 7 自定义 UINavigationController 动画因目标 Controller 中的 mapView 而失败,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/22151910/
