Question

我有两个视图（视图1和视图2）。 view1包含一个按钮，当我点击这个按钮时，我去查看2.我想要显示view2的方向纵向和横向。对于view2我创建2个UiviewController一个用于横向和seconde用于纵向方向和相同的Class.but不起作用。任何人都有任何想法？

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
     return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

Answer 1

为什么你需要 TWO ViewControllers只是为了定位......？

HEre Simple scenario，

创建2个视图

Portrait＆amp;＆amp;
景观视图，根据您的要求。

遵循这样的事情。

-(BOOL)shouldAutorotate{
    return YES;
}

- (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    [self orientationChanged:toInterfaceOrientation];
}

-(void)orientationChanged:(UIInterfaceOrientation)orientation{
    NSLog(@"orientation change");
   // UIDeviceOrientation deviceOrientation = [[object object] orientation];

    if(orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown){
        NSLog(@"Changed Orientation To Portrait");
        self.viewPortrait.hidden = NO;
        self.viewLandscape.hidden = YES;
    }

else if(orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight){
    NSLog(@"Changed Orientation To Landscape");

    self.viewPortrait.hidden = YES;
    self.viewLandscape.hidden = NO;
    }  
}

并且您应该设置所需的所有方向。

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
}

在故事板中使用ios 5进行定位
