UINavigationController：在相反方向彈出視圖控制器

Question

我試圖調用[[self navigationController] popViewControllerAnimated:YES]，但使動畫從右向左滑動，而不是從左向右滑動。任何簡單的方法來做到這一點？我想返回到前一個視圖。任何幫助表示讚賞。謝謝！

Answer 1

這是可能的，看看我用了一段時間後面的代碼，並嘗試使它爲自己工作。鬱可唯需要改變setAnimationTransition

[UIView beginAnimations:nil context:NULL]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 
[UIView setAnimationDuration:0.75]; 
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO]; 
[UIView commitAnimations]; 

[UIView beginAnimations:nil context:NULL]; 
[UIView setAnimationDelay:0.375]; 
[self.navigationController popViewControllerAnimated:NO]; 
[UIView commitAnimations]; 

有幾種不同類型的默認動畫使用，蘋果網站說，這種動畫是可能的：

typedef enum { 
    UIViewAnimationTransitionNone, 
    UIViewAnimationTransitionFlipFromLeft, 
    UIViewAnimationTransitionFlipFromRight, 
    UIViewAnimationTransitionCurlUp, 
    UIViewAnimationTransitionCurlDown, 
} UIViewAnimationTransition; 

所以你的情況，你會想使用以下內容：

[UIView beginAnimations:nil context:nil]; 
    [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut]; 
    [UIView setAnimationDuration:0.75]; 
    [self.navigationController popViewControllerAnimated:NO]; 
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO]; 
    [UIView commitAnimations];

這是如何在相反方向彈出視圖控制器。它爲我工作100％

CATransition *transition = [CATransition animation]; 
    transition.duration = 0.45; 
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]; 
    transition.type = kCATransitionFromRight; 
    [transition setType:kCATransitionPush]; 
    transition.subtype = kCATransitionFromRight; 
    [self.navigationController.view.layer addAnimation:transition forKey:nil]; 
    [self.navigationController popViewControllerAnimated:NO];
