Xcode中的視圖控制器動畫

Question

我需要在用戶單擊按鈕時爲視圖添加動畫。我使用下面的代碼動畫

應用代表

ViewController2 *vc2_controller = [[ViewController2 alloc]init]; 

    UINavigationController *baseViewController = [[UINavigationController alloc]initWithRootViewController:vc2_controller]; 
    [self.window addSubview:baseViewController.view]; 
    self.window.rootViewController = vc2_controller; 



    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController]; 

    [self.window addSubview:navigationController.view]; 


    self.viewController = [[vc1controller alloc]initWithNibName:nil bundle:nil]; 

//ViewController1.m - 這是工作

[self.navigationController pushSlideViewController:self.navigationController]; 

我創建的類 //分類

內部函數定義

- (void)pushSlideViewController:(UIViewController *)viewController 
{ 
    // NSLog(@"In Navigation Controller"); 

    //[UIView transitionWithView:viewController.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromLeft animations:nil completion:nil]; 
    CGRect screensize = [[UIScreen mainScreen]bounds]; 

    [UIView animateWithDuration:0.5 animations:^{ 

     NSLog(@"In View ANimatin"); 
     CGRect current_rect = viewController.view.frame; 
     viewController.view.frame = current_rect; 
     current_rect.origin.x = screensize.size.width-50; 
     viewController.view.frame = current_rect; 

    }]; 

} 

現在我從View中調用ViewController1.m Controller2.m - 動畫不能正常工作

ViewController1 *view_control = [[ViewController1 alloc]init]; 

[self.navigationController popSlideViewController:view_control]; 

//Category 
-(void)popSlideViewController:(UIViewController *)viewController 
{ 
    CGRect screensize = [[UIScreen mainScreen]bounds]; 
    //NSLog(@"In Pop"); 
    [UIView animateWithDuration:0.5 animations:^{ 

     //View is not coming to original position. 
     CGRect current_rect = viewController.view.frame; 
     NSLog(@"In View ANimatin %f",current_rect.origin.x); 
     viewController.view.frame = current_rect; 
     current_rect.origin.x = 0.0; 
     viewController.view.frame = current_rect; 

    }]; 
} 

注：我沒有使用iOS5的:-)

感謝，

你從VC1，你說哪個，裝VC2，工作正常。然後，你試圖從VC2加載VC1，這是問題所在 - VC1仍然在VC2後面加載，所以你只需要以類似的方式關閉VC2，就像你第一次啓動VC2一樣，只需要動畫它退出屏幕，將其從視圖中移除，然後釋放它（除非您在顯示時釋放它）。另外，您可以使用內置的方法，

presentViewController:animated:completion: 

和

dismissViewControllerAnimated:completion: 

有自己的動畫。
