iPhone/iPad通用應用程序定位

Question

我正在開發通用應用程序。現在我想爲這兩種方式設置方向當在iPhone上啓動應用程序時，它將以縱向模式打開，當應用程序在iPad上啓動時，它將以橫向模式打開。

可能嗎？

Answer 1

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad && UIInterfaceOrientationIsLandscape(interfaceOrientation)) { 
     return YES; 
    } else if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone && UIInterfaceOrientationIsPortrait(interfaceOrientation)) { 
     return YES; 
    } 

    return NO; 
} 

Answer 2

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { 
    // The device is an iPad running iPhone 3.2 or later. 
    // Rotate to landscape 
} 
else { 
    // The device is an iPhone or iPod touch. 
    // Rotate to portrait 
} 

「How does one get UI_USER_INTERFACE_IDOM to work with iOS 3.2?」

Answer 3

此外u可以使用[的UIDevice currentDevice] .MODEL或[的UIDevice currentDevice] .systemName識別裝置則在shouldAutoRotate方法返回interfaceOrientation == UIInterfaceOrientationLandscapeLeft爲ipad和interfaceOrientation ==基於設備類型的iphone UIInterfaceOrientationPortrait。

Answer 4

您可以通過向您的應用程序代理添加一些代碼來達到此目的，每my answer here。

SWIFT代碼：

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> Int { 
    if UIDevice.currentDevice().userInterfaceIdiom == .Phone { 
     return Int(UIInterfaceOrientationMask.Portrait.rawValue) 
    } else { 
     return Int(UIInterfaceOrientationMask.LandscapeLeft.rawValue | UIInterfaceOrientationMask.LandscapeRight.rawValue) 
    } 
}
