如何將風景圖像轉換爲IOS6中的portrate圖像？

Question

我想從相機拍照風景模式，我想在肖像模式中顯示該圖像iOS6。我無法在縱向模式下旋轉圖像。

Answer 1

你想旋轉，那麼你要做的旋轉圖像？
如果你想只顯示它在視圖中，UIImageView包裝它，旋轉ImageView的並插入到視圖：

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    UIImage* image = [[info objectForKey: UIImagePickerControllerOriginalImage] fixOrientation]; 
    UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; 
    imageView.transform = CGAffineTransformMakeRotation(M_PI * 90/180); 
    [self.view addSubview:imageView]; 
}
