iPhone的“相機重疊”視圖未在橫向模式下顯示

Question

我已經使用UIImagePickerViewController啟動了相機並嘗試覆蓋另一個視圖。 我已經為“風景”模式設置了“疊加”視圖，但是在疊加到“相機”視圖后，它仍以“人像”模式顯示。

Answer 1

我已經解決了這個問題，方法是旋轉疊加視圖，如下所示：tmpCamera.cameraOverlayView.transform = CGAffineTransformRotate（CGAffineTransformIdentity，117.81）; 希望這可以節省一些時間:)

Answer 2

   first you selected only potrait mode in app settting
then use this function in viewdidLoad
//Orientation View into LandScape Mode
    -(void)orientationToLandscape{
        CGAffineTransform rotateTransform;
        switch ([UIApplication sharedApplication].statusBarOrientation) {
            case UIInterfaceOrientationPortrait:
                rotateTransform = CGAffineTransformMakeRotation(-90*M_PI/180.0);
                break;
            case UIInterfaceOrientationPortraitUpsideDown:
                rotateTransform = CGAffineTransformMakeRotation(90*M_PI/180.0);
                break;

            default:
                rotateTransform = CGAffineTransformMakeRotation(0);
                break;
        }

        rotateTransform = CGAffineTransformTranslate(rotateTransform, +90.0, +90.0);
        [self.view setTransform:rotateTransform];
