Question

当我在willRotateToInterfaceOrientation和animates之间切换时，我已经实施了方法orientation和我的iPhone应用landscape移动portrait。

我的问题是：是否可以使用不同类型的animation？是否有其他内置的animations我可以用于transition？或者我可以自己篡改它吗？任何人都可以向我展示更改animation的代码示例吗？

绝对有可能。这是一个自定义动画，我将几个视图移动到不同的地方：

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation 
                                duration:(NSTimeInterval)duration {
    [UIView beginAnimations:nil context:NULL]; {
        [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
        [UIView setAnimationDuration:0.5];
        [UIView setAnimationDelegate:self];

        if (toInterfaceOrientation == UIInterfaceOrientationPortrait ||
            toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
            [myImage setCenter:CGPointMake(384.0,170.0)];
            [firstLabel setCenter:CGPointMake(235.0,358.0)];
            [secondLabel setCenter:CGPointMake(519.0,358.0)];
            [button0 setCenter:CGPointMake(164.0,508.0)];
            [button1 setCenter:CGPointMake(384.0,508.0)];
            [button2 setCenter:CGPointMake(604.0,508.0)];
            [button3 setCenter:CGPointMake(274.0,666.0)];
            [button4 setCenter:CGPointMake(494.0,666.0)];
            [button5 setCenter:CGPointMake(164.0,824.0)];
            [button6 setCenter:CGPointMake(384.0,824.0)];
            [button7 setCenter:CGPointMake(604.0,824.0)];
            [button8 setCenter:CGPointMake(164.0,954.0)];
            [button9 setCenter:CGPointMake(604.0,954.0)];       
        } else {
            [myImage setCenter:CGPointMake(350.0,173.0)];
            [firstLabel setCenter:CGPointMake(844.0,66.0)];
            [secondLabel setCenter:CGPointMake(844.0,114.0)];
            [button0 setCenter:CGPointMake(140.0,450.0)];
            [button1 setCenter:CGPointMake(388.0,450.0)];
            [button2 setCenter:CGPointMake(636.0,450.0)];
            [button3 setCenter:CGPointMake(884.0,450.0)];
            [button4 setCenter:CGPointMake(140.0,638.0)];
            [button5 setCenter:CGPointMake(388.0,638.0)];
            [button6 setCenter:CGPointMake(636.0,638.0)];
            [button7 setCenter:CGPointMake(884.0,638.0)];
            [button8 setCenter:CGPointMake(844.0,190.0)];
            [button9 setCenter:CGPointMake(844.0,280.0)];       
        }   
    } [UIView commitAnimations];            
}

这很好用，因为每张图像都飞过屏幕，然后降落在一个新的位置。你可以使用这样的东西来创造各种效果。

是否可以在我的应用程序中更改iPhone方向动画
