視圖控制器的轉換 - 從左到右

Question

我沒有使用導航控制器，而我正在使用故事板。

我必須從1視圖控制器轉換到其他，我正在使用segue。

現在我將segue樣式設置爲Custom，並在相應的類中覆蓋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，目標視圖控制器modalTransitionStyle也有一個屬性。

所以現在，源代碼VC從左到右好像被推入，但我想表明它正在被目標視圖控制器推送。相反，目標VC在默認情況下會執行「遮蓋垂直」，並且modalTransitionStyle屬性只有四個選項可用，但其中沒有一個適用於我。

我想讓它工作，這個動畫應該被添加到一些超級視圖層，一個超級視圖從這兩個視圖控制器已經呈現。但是，有沒有這樣的上海華..

通常你會給一個storyboardId到destinationController從sourceViewController這樣稱呼它：

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

或者，您也可以手動做這樣的：

// 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; 
     } 
    }]; 

** EDIT **

逆函數（類似於在導航的返回按鈕控制器）：

// 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]; 
    } 
}];

所有在我的應用程序的ViewControllers從MyViewController繼承它，此外還有一些其他的默認行爲，有此屬性：

@property(readwrite, nonatomic) BOOL slideFromSide; 

而這種代碼：

- (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]; 
    } 
} 

然後，在我想滑入的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; 
} 

調用一個新的視圖控制器就像是正常的：

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