当我使用交互式委托调用动画时,我的视图控制器上有自定义动画过渡,动画工作正常。当我添加正常工作的交互式组件时。但是,当我在使用交互式组件之前使用按钮来解除像我之前那样,动画完成块没有被调用。
下面是动画块。起初我使用动画块的延迟/选项变化并将其更改为更简单的动画/完成以确保它不是该功能。如果我从动画块中删除所有代码,它将执行并关闭控制器(尽管没有动画)。我不知道什么是冷错,也找不到类似的问题。
手势只是向右滑动手指以解除模态......这很好用。当我删除交互式部分时,按下按钮时动画运行正常。仅当我将交互式组件附加到View Controller时才会发生这种情况。
这是动画块:
[UIView animateWithDuration:PRESENT_DURATION animations:^{
CGAffineTransform newTransform = fromViewController.view.transform;
newTransform = CGAffineTransformTranslate(transform, adjustedBounds.size.width, height);
fromViewController.view.transform = newTransform;
toViewController.view.alpha = 1;
} completion:^(BOOL finished){
NSLog(@"Finished Animation");
if ([transitionContext transitionWasCancelled]) {
[transitionContext completeTransition:NO];
} else {
[fromViewController.view removeFromSuperview];
[transitionContext completeTransition:YES];
}
}];
这是我将animate和interactionController附加到ViewController
的地方- (IBAction)settingsButtonClicked:(id)sender
{
UINavigationController *navigationController =[[self storyboard] instantiateViewControllerWithIdentifier:@"SettingsNavigationViewController"];
navigationController.modalPresentationStyle = UIModalPresentationCustom;
navigationController.transitioningDelegate = self;
navigationController.edgesForExtendedLayout = UIRectEdgeNone;
[self presentViewController:navigationController animated:YES completion:^{
id animator = [navigationController.transitioningDelegate animationControllerForDismissedController:self];
id interactor = [navigationController.transitioningDelegate interactionControllerForDismissal:animator];
if ([interactor respondsToSelector:@selector(attachToViewController:)]) {
[interactor attachToViewController:self];
}
}];
navigationController.view.superview.frame = CGRectMake(0, 0, navigationController.view.frame.size.width, self.view.frame.size.height);
}
答案 0 :(得分:1)
我在使用交互式百分比驱动转换时遇到了同样的问题,因为平移驱动手势会很快发生并且在启动后会立即取消。我相信在演示之后过早地调用完成/取消会在Apple代码中显示某个错误,该错误会忘记调用正在进行的动画的完成块。
最后通过覆盖cancelInteractiveTransition来更新它,使用0%更新它:
override func cancelInteractiveTransition() {
updateInteractiveTransition(0)
super.cancelInteractiveTransition()
}
在obj C中
-(void)cancelInteractiveTransition {
[self updateInteractiveTransition:0];
[super cancelInteractiveTransition];
}
希望这能让你接近答案,我会在finishIneractiveTransition中做类似的事情,也许尝试在下一个运行循环中调用super来调用
编辑:你仍然可以通过以很快的速度来回滑动来完成动画,所以我不得不添加一个小延迟并立即解决这个问题:
override func cancelInteractiveTransition() {
if percentComplete > 0.1 {
updateInteractiveTransition(0)
super.cancelInteractiveTransition()
} else {
var dispatchTime: dispatch_time_t = dispatch_time(DISPATCH_TIME_NOW, Int64(0.1 * Double(NSEC_PER_SEC)))
dispatch_after(dispatchTime, dispatch_get_main_queue(), {
self.updateInteractiveTransition(0)
super.cancelInteractiveTransition()
})
}
}
override func finishInteractiveTransition() {
if percentComplete > 0.1 {
super.finishInteractiveTransition()
} else {
var dispatchTime: dispatch_time_t = dispatch_time(DISPATCH_TIME_NOW, Int64(0.1 * Double(NSEC_PER_SEC)))
dispatch_after(dispatchTime, dispatch_get_main_queue(), {
super.finishInteractiveTransition()
})
}
}
