【问题描述】：

如何使整个应用程序的背景相同。而不是去另一个ViewController 有一些动画（推，弹出，翻滚等）。 我只想用一些动画改变前景视图。下一个视图应该在另一个 ViewController 中

例如让两个彩色屏幕成为 UIView。单击第一个视图上的按钮时，我想移动 view1 幻灯片 view2。

Anyway the background need to remain unchanged Note: With different view controllers

UINavigationController - Keep Background Image Across All Views的可能重复

【参考方案1】：

试试这个代码：

- (IBAction)btnExit:(id)sender 
    [self setFrame:CGRectMake(-self.frame.size.width
                                 ,200
                                 ,self.frame.size.width
                                 , self.frame.size.height
                                 )];

    CATransition *animation = [CATransition animation];
    [animation setType:kCATransitionPush];
    [animation setSubtype:kCATransitionFromRight];
    [animation setDuration:.50];
    [animation setDelegate:self];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
    CALayer *layer = [self layer];
    [layer addAnimation:animation forKey:nil];


- (IBAction)btnEnter:(id)sender 
    [self setFrame:CGRectMake(10
                                 ,200
                                 ,self.frame.size.width
                                 , self.frame.size.height
                                 )];

    CATransition *animation = [CATransition animation];
    [animation setType:kCATransitionPush];
    [animation setSubtype:kCATransitionFromLeft];
    [animation setDuration:.50];
    [animation setDelegate:self];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
    CALayer *layer = [self layer];
    [layer addAnimation:animation forKey:nil];

通过这个简单的代码，我在屏幕内移动（使用btnEnter）myView（开始时在屏幕外）使用动画，然后（btnExit）使用另一个动画移动。

你可以使用很多动画，我选择了一个。

记得在你的类定义中添加CAAnimationDelegate。

背景总是一样的。 (UIViewController 的视图)

【参考方案2】：

您可以更改动画持续时间 2

 [UIView animateWithDuration:1 animations:^
            [view1 setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];


        ];

    [UIView animateWithDuration:1 animations:^
            [view2 setFrame:CGRectMake( view1.frame.size.width,0, self.view.frame.size.width, self.view.frame.size.height)];


        ];

或

 [UIView animateWithDuration:1 animations:^
                [view2 setFrame:CGRectMake( view1.frame.size.width,0, self.view.frame.size.width, self.view.frame.size.height)];

         [view1 setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];

            ];
