如何在IOS 6中将风景图像转换为肖像图像？

Question

我正尝试在风景模式下从相机拍照，我想在 iOS6 中以人像模式显示该图像。我无法以纵向模式旋转图像。

你想旋转，然后你要用旋转的图像做什么？ 如果您只想在视图中显示它，请将其包装在UIImageView中，旋转imageView并插入视图：

-(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];
}
