如何检查appdelegate的风景和肖像模式？ [英] How to check landscape and portrait mode on appdelegate?

问题描述

我要以横向和纵向模式运行应用程序，

i want to run app in landscape and portrait mode,

如何在Appdelegate上检查横向和纵向模式？

How to check landscape and portrait mode on Appdelegate?

我尝试调用

- (BOOL) isPad{ 
#ifdef UI_USER_INTERFACE_IDIOM
    return (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
#else
    return NO;
#endif
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    if ([self isPad]) {
        NSLog(@"is pad method call");
        return YES;
    }
    else 
    {
        return UIInterfaceOrientationIsPortrait(interfaceOrientation);
    }

}



- (BOOL)isPadPortrait
{

    return (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad
            && (self.interfaceOrientation == UIInterfaceOrientationPortrait
                || self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown));
}


- (BOOL)isPadLandscape
{

    return (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad
            && (self.interfaceOrientation == UIInterfaceOrientationLandscapeRight
                || self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft));

}

但出现错误
未找到属性接口方向对象类型appdelegate。

but gives error Property interface orientation not found on object of type appdelegate.

我如何做到这一点？

推荐答案

p>您应该使用检查iPad的当前方向。我建议您在每个视图检查这些条件，并根据当前的方向行事：

You should check the current orientation of your iPad using. I would recommend you to check these conditions on every view and act according to the current orientation:

if([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeLeft)
{
      //Do what you want in Landscape Left
}
else if([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeRight)
{
      //Do what you want in Landscape Right
}
else if([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait)
{
     //Do what you want in Portrait
}
else if([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
      //Do what you want in Portrait Upside Down
}

我希望这可以帮助你。 ：）
