视图控制器的转换 – 从左到右

我没有使用导航控制器，我正在使用故事板。

我必须从1个视图控制器转换到其他视图，我正在使用segue。

现在我将segue样式设置为Custom，并在相应的类中重写perform方法。

 -(void)perform { UIViewController *sourceViewController = [self sourceViewController]; UIViewController *destinationViewController = [self destinationViewController]; CATransition *transition = [CATransition animation]; transition.duration = 0.25; transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]; transition.type = kCATransitionPush; transition.subtype = kCATransitionFromLeft; [sourceViewController.view.layer addAnimation:transition forKey:kCATransition];animated:NO]; [sourceViewController presentViewController:destinationViewController animated:YES completion:nil]; } 

但是目标视图控制器modalTransitionStyle也有一个属性。

所以现在，源VC从左向右移动就好像它被推动一样，但我想表明它正被目标视图控制器推送。 相反，目标VC默认执行“覆盖垂直”，并且modalTransitionStyle属性只有四个选项可用，但这些选项都不适用于我。

我认为要使它工作，这个动画应该添加到一些superview层，一个superview层，从中可以看到两个视图控制器。 但是没有这样的超级视图..

通常你会给storyController一个storyboardId，并从sourceViewController这样调用它：

 //push next view UIStoryboard *storyboard = self.storyboard; YourViewControllerClass *destVC = [storyboard instantiateViewControllerWithIdentifier:@"StoryboardID"]; [self.navigationController pushViewController:destVC animated:YES]; 

您可以选择手动执行此操作：

  // Get the views. UIView * fromView = sourceViewController.view; UIView * toView = destinationViewController.view; // Get the size of the view area. CGRect viewSize = fromView.frame; // Add the toView to the fromView [fromView.superview addSubview:toView]; // Position it off screen. toView.frame = CGRectMake( 320 , viewSize.origin.y, 320, viewSize.size.height); [UIView animateWithDuration:0.4 animations: ^{ // Animate the views on and off the screen. This will appear to slide. fromView.frame =CGRectMake( -320 , viewSize.origin.y, 320, viewSize.size.height); toView.frame =CGRectMake(0, viewSize.origin.y, 320, viewSize.size.height); } completion:^(BOOL finished) { if (finished) { // Remove the old view from its parent. [fromView removeFromSuperview]; //I use it to have navigationnBar and TabBar at the same time //self.tabBarController.selectedIndex = indexPath.row+1; } }];

反函数（类似于导航控制器中的后退按钮）：

 // Get the views. UIView * fromView = fromViewController.view; UIView * toView = destViewController.view; // Get the size of the view area. CGRect viewSize = fromView.frame; // Add the to view to the tab bar view. [fromView.superview addSubview:toView]; // Position it off screen. toView.frame = CGRectMake( -320 , viewSize.origin.y, 320, viewSize.size.height); [UIView animateWithDuration:0.4 animations: ^{ // Animate the views on and off the screen. This will appear to slide. fromView.frame =CGRectMake( 320 , viewSize.origin.y, 320, viewSize.size.height); toView.frame =CGRectMake(0, viewSize.origin.y, 320, viewSize.size.height); } completion:^(BOOL finished) { if (finished) { // Remove the old view from the tabbar view. [fromView removeFromSuperview]; } }];

我的应用程序中的所有ViewControllers都inheritance自MyViewController ，除了一些其他默认行为外，还具有此属性：

 @property(readwrite, nonatomic) BOOL slideFromSide; 

这段代码：

 - (void) presentViewController: (UIViewController*) vc animated: (BOOL) flag completion: (void (^)(void)) completion { BOOL slideIn = NO; if ([vc isKindOfClass: [MyViewController class]]) { MyViewController *svc = (MyViewController*) vc; slideIn = svc.slideFromSide; } if (slideIn) { [self addChildViewController: vc]; [self.view addSubview: vc.view]; CGRect frame = vc.view.frame; frame.origin.x = frame.size.width; vc.view.frame = frame; frame.origin.x = 0; [UIView animateWithDuration: 0.33 animations: ^{ vc.view.frame = frame; } ]; } else { [super presentViewController: vc animated: flag completion: completion]; } } - (IBAction) backAction: (id) sender { if (_slideFromSide) { CGRect frame = self.view.frame; frame.origin.x = frame.size.width; [UIView animateWithDuration: 0.33 animations: ^{ self.view.frame = frame; } completion:^(BOOL finished) { [self removeFromParentViewController]; } ]; } else { [self dismissViewControllerAnimated: YES completion: nil]; } } 

然后，在我想要滑入的ViewControllers中，我有：

 - (id) initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName: nibNameOrNil bundle: nibBundleOrNil]; if (self) { self.slideFromSide = YES; // Whatever else you want to do } return self; } 

调用新的ViewController就像正常一样：

 WhateverViewController *vc = [WhateverViewController alloc] initWithNibName: nil bundle: nil]; [self presentViewController: vc animated: YES completion: nil];
