如何在IOS6中将景观图像转换成图像？

Question

我试图在景观模式下从相机中拍摄照片，我想在iOS6中以肖像模式显示该图像。我不能在肖像模式下旋转图像。

Answer 1

你想要旋转，然后你要做什么旋转图像？

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];
}
