iphone - 将ViewController推到左边-简单吗？

Question

我试图让我的 ViewController 以与标准 PushViewConrtoller 相同的速度从左向右滑动，我没有使用导航栏，也不想使用 Modal，有没有一种简单的方法可以做到这一点，我在不同的线程上看到了很多变体，但它们都不能正常工作!

我正在使用带有以下代码的导航 Controller 来实现右推...

- (IBAction)launch1990:(id)sender {

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"1990Storyboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"1990"];
[self.navigationController pushViewController:vc animated:YES];
}

UIStroryBoard 当您推送 View Controller 或 segues 时，它不允许您自定义太多。我最终做的是覆盖执行方法并使用 QuartzCore 动画来自定义我们的转换。我对 UIStoryBoardSegue 进行了子类化并覆盖了执行函数。

下面自定义 Push 或 Pop，然后自定义 Segues。 (对于segues，请记住将类更改为IB中的自定义类)。

要通过正常的弹出或推送来执行此操作(这会执行淡入淡出动画，请根据您的情况进行调整):

    #import <QuartzCore/QuartzCore.h>


 - (IBAction)launch1990:(id)sender {
    CATransition* transition = [CATransition animation];
    transition.duration = .45;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionFade;
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"1990Storyboard" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"1990"];
    [self.navigationController pushViewController:vc animated:NO];
  }

要从segue中执行此操作:

//ZHCustomSegue.h
#import <Foundation/Foundation.h>

@interface ZHCustomSegue : UIStoryboardSegue

@end


//  ZHCustomSegue.m
#import "ZHCustomSegue.h"
#import "QuartzCore/QuartzCore.h"

@implementation ZHCustomSegue


-(void)perform {

    UIViewController *sourceViewController = (UIViewController*)[self sourceViewController];
    UIViewController *destinationController = (UIViewController*)[self destinationViewController];

    CATransition* transition = [CATransition animation];
    transition.duration = .45;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush,   kCATransitionReveal, kCATransitionFade
   //transition.subtype = kCATransitionFromLeft; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom



    [sourceViewController.navigationController.view.layer addAnimation:transition
                                                            forKey:kCATransition];

    [sourceViewController.navigationController pushViewController:destinationController animated:NO];

}
@end
