当用户按下uiviewcontroller导航栏的默认后退按钮(不是自定义按钮)时,我试图产生一个自定义效果。我试图将视图移到某个Y位置,然后弹出视图并让视图控制器消失。按下后退按钮时的自定义动画 - iOS
我尝试了两种方法:
方法1
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[UIView animateWithDuration:0.2 animations:^{
self.cvCell.frame = self.selectedCellFrame;
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.75
animations:^{
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.navigationController.view cache:NO];
} completion:^(BOOL finished) {
[self.navigationController popViewControllerAnimated:NO];
}];
}];
}
方法2:
-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
if ([self.navigationController.viewControllers indexOfObject:self]==NSNotFound) {
[UIView animateWithDuration:0.2 animations:^{
self.cvCell.frame = self.selectedCellFrame;
} completion:^(BOOL finished) {
CATransition *transition = [CATransition animation];
[transition setDuration:0.75];
[transition setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[transition setType:kCATransitionReveal];
[transition setSubtype:kCATransitionFromLeft];
[transition setDelegate:self];
[self.navigationController.view.layer addAnimation:transition forKey:nil];
}];
}
}
在这两种情况下,视图上的UIView动画会踢之前就消失in。 关于实现这个的任何建议?
我试图弹出从B.视图控制器A I登陆b。在使用自定义动画赛格瑞(我使用了一个故事板)。我是否应该创建另一个自定义segue来弹出此视图控制器? – 2015-04-04 05:56:03
是的,如果它自动返回,它可能还需要重新配置“后退”按钮。查看后'prepareForSegue:发件人:'只适用于前进方向,向后移动使用'prepareForUnwind:发件人:'更多信息请点击: [http://spin.atomicobject.com/2014/12/ 01 /程序-IOS退绕-SEGUE /(http://spin.atomicobject.com/2014/12/01/program-ios-unwind-segue/) – 2015-04-05 15:38:07
