Ipad/Iphone - UIView 中的图像旋转

Question

如何旋转充满内容的 UIView。我在 UIView 旋转方面遇到问题。有人可以帮帮我吗？？？请给我一些类似的逐步示例。

Answer 1

这很简单：

myUIView.transform = CGAffineTransformMakeRotation(M_PI * 0.5); 

这会将整个事情向右转 90 度，包括内容在内。
CGAffineTransformMakeRotation 的参数以弧度为单位...

Answer 2

嘿，非常感谢您的回复。与旋转相关的问题已解决，但我在横向模式下仍然遇到一些问题，我使用此代码为两个 UIView 制作动画，但在横向模式下，一个视图没有出现，我想要一个理想的解决方案。

我当前正在使用的旋转代码...

- (void)viewDidLoad 
{

    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:)   name:UIDeviceOrientationDidChangeNotification object:nil];

}


- (void)didRotate:(NSNotification *)notification {

    UIDeviceOrientation orientation = [[notification object] orientation];

    if (orientation == UIDeviceOrientationLandscapeLeft) 
    {

        CGRect contentRect = CGRectMake(0,0, 1024, 748);
        self.view.bounds = contentRect;
        [self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
    } 
    else if (orientation == UIDeviceOrientationLandscapeRight) 
    {

        CGRect contentRect = CGRectMake(0,0, 1024, 748);
        self.view.bounds = contentRect; 


        [self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
    }

    else if (orientation == UIDeviceOrientationPortraitUpsideDown) 
    {

        CGRect contentRect = CGRectMake(0,0, 768, 1024);
        self.view.bounds = contentRect;
        [self.view setTransform:CGAffineTransformMakeRotation(M_PI)];
    } 
    else if (orientation == UIDeviceOrientationPortrait) {

        CGRect contentRect = CGRectMake(0,0, 768, 1024);
        self.view.bounds = contentRect;
        [self.view setTransform:CGAffineTransformMakeRotation(0.0)];
    }


}

UIView 氨基化代码。

self.loginView.hidden=NO;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
self.AcTypeView.transform=CGAffineTransformMakeTranslation(0, 493);
[UIView commitAnimations];



[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:2.0];

self.loginView.transform=CGAffineTransformMakeTranslation(0, -700);
[UIView commitAnimations];




Thanks!!!!
