如何在IOS 8中強(qiáng)制查看控制器方向？在iOS 8之前，我們將下面的代碼與支持接口定向和應(yīng)自旋委托方法強(qiáng)制應(yīng)用程序定向到任何特定方向。我使用下面的代碼片段以編程方式將應(yīng)用程序旋轉(zhuǎn)到所需的方向。首先，我改變了狀態(tài)欄的方向。然后，只要呈現(xiàn)并立即丟棄一個(gè)模態(tài)視圖，就可以將視圖旋轉(zhuǎn)到所需的方向。[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:YES];
UIViewController *c = [[UIViewController alloc]init];[self presentViewController:vc animated:NO completion:nil];
[self dismissViewControllerAnimated:NO completion:nil];但這在iOS 8中是失敗的。而且，我在堆棧溢出中看到了一些答案，人們建議我們應(yīng)該從iOS 8開始始終避免這種方法。更具體地說(shuō)，我的應(yīng)用程序是一種通用的應(yīng)用程序類型。總共有三個(gè)控制器。第一視圖控制器-它應(yīng)該支持iPad中的所有方向，只支持iPhone中的肖像畫(主頁(yè)按鈕)。第二視圖控制器-在任何情況下都應(yīng)支持景觀權(quán)第三視圖控制器-在任何情況下都應(yīng)支持景觀權(quán)我們使用導(dǎo)航控制器進(jìn)行頁(yè)面導(dǎo)航。從第一個(gè)視圖控制器，在一個(gè)按鈕單擊操作，我們推動(dòng)第二個(gè)在堆棧上。因此，當(dāng)?shù)诙€(gè)視圖控制器到達(dá)時(shí)，不管設(shè)備的方向如何，應(yīng)用程序應(yīng)該只鎖定在景觀右側(cè)。下面是我的shouldAutorotate和supportedInterfaceOrientations方法在第二視圖控制器和第三視圖控制器中。-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscapeRight;}-(BOOL)shouldAutorotate {
return NO;}是否有任何解決方案或任何更好的方法鎖定一個(gè)視圖控制器，特別是iOS 8的方向。請(qǐng)幫助！

}}SWIFT 3
extension UINavigationController {
open override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return visibleViewController?.supportedInterfaceOrientations ?? super.supportedInterfaceOrientations }
open override var shouldAutorotate: Bool {

禁用旋轉(zhuǎn)
class ViewController: UIViewController {
override func shouldAutorotate() -> Bool {
return false
}}鎖定到特定方向
class ViewController: UIViewController {
override func supportedInterfaceOrientations() -> Int {
return Int(UIInterfaceOrientationMask.Landscape.rawValue)
