iphone – 只有一个视图在xcode中自动旋转？

概述好的,所以我目前有3个视图,我只需要其中一个自动旋转到任何方向,而其余的保持纵向.现在我的设置是一个splashviewcontroller淡入视图A,内部视图A是一个切换到视图B的按钮.我想要的是视图B能够旋转到任何方向. 当我在splashviewcontroller中为shouldautorotatetointerfaceorientation返回YES时,每个视图都会旋转,因为这是父视图. 好的,所以我目前有3个视图,我只需要其中一个自动旋转到任何方向,而其余的保持纵向.现在我的设置是一个splashvIEwcontroller淡入视图A,内部视图A是一个切换到视图B的按钮.我想要的是视图B能够旋转到任何方向.

当我在splashvIEwcontroller中为shouldautorotatetointerfaceorIEntation返回YES时,每个视图都会旋转,因为这是父视图.当我仅在splashvIEw中返回肖像时,即使其他视图返回YES,也不会旋转.有没有办法让视图B旋转？如果你能提供代码,我愿意手动完成.谢谢

解决方法 你可以手动管理任何所需的UIVIEw对象的旋转,如下所示：

编辑：

在init或vIEwDIDLoad中

- (voID)vIEwDIDLoad{    [[NSNotificationCenter defaultCenter] addobserver:self selector:@selector(rotate) name:UIDeviceOrIEntationDIDChangeNotification object:nil];    [super vIEwDIDLoad];}#define degreesToRadian(x) (M_PI * (x) / 180.0)-(voID)rotate{    self.vIEw.bounds = CGRectMake(0,0);    if ([UIDevice currentDevice].orIEntation == UIInterfaceOrIEntationPortrait){        CGAffinetransform landscapetransform = CGAffinetransformMakeRotation(degreesToRadian(0));        landscapetransform = CGAffinetransformTranslate (landscapetransform,0.0,0.0);        self.vIEw.bounds = CGRectMake(self.vIEw.bounds.origin.x,self.vIEw.bounds.origin.y,320,480);        [self.vIEw settransform:landscapetransform];    } else if ([UIDevice currentDevice].orIEntation == UIInterfaceOrIEntationPortraitUpsIDeDown){        CGAffinetransform landscapetransform = CGAffinetransformMakeRotation(degreesToRadian(180));        landscapetransform = CGAffinetransformTranslate (landscapetransform,480);        [self.vIEw settransform:landscapetransform];    } else if ([UIDevice currentDevice].orIEntation == UIInterfaceOrIEntationLandscapeRight){        CGAffinetransform landscapetransform = CGAffinetransformMakeRotation(degreesToRadian(90));         landscapetransform = CGAffinetransformTranslate (landscapetransform,0.0);         self.vIEw.bounds = CGRectMake(self.vIEw.bounds.origin.x,480,320);         [self.vIEw settransform:landscapetransform];    }else if ([UIDevice currentDevice].orIEntation == UIInterfaceOrIEntationLandscapeleft){        CGAffinetransform landscapetransform = CGAffinetransformMakeRotation(degreesToRadian(270));        landscapetransform = CGAffinetransformTranslate (landscapetransform,0.0);        self.vIEw.bounds = CGRectMake(self.vIEw.bounds.origin.x,320);         [self.vIEw settransform:landscapetransform];    }}
