Save image to album

[jasanchezsa]

Hello, first congratulations for the project. Sorry for my English.

I tried to save the image in the album but does not save the transformed image.

UIImageWriteToSavedPhotosAlbum([self captureView:self.view], self, @selector(image:didFinishSavingWithError:contextInfo:), nil);

- (UIImage *)captureView:(UIView *)view
{
    CGRect rect = [self.view bounds]; 
    UIGraphicsBeginImageContextWithOptions(rect.size, YES, 0.0);
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return viewImage;
}

Thank you very much.

You need to use this after renderInContext

I dont understand how to use this method:

- (UIImage *)imageWithTransform:(CATransform3D)transform anchorPoint:(CGPoint)anchorPoint;

My code:

- (void)createAndApplyQuad
{  
    AGQuad quad = AGQuadMakeWithCGPoints(self.topLeftControl.frame.origin,
                                         self.topRightControl.frame.origin,
                                         self.bottomRightControl.frame.origin,
                                         self.bottomLeftControl.frame.origin);

    if(AGQuadIsValid(quad))
    {
        self.imageViewMaskBald.layer.quadrilateral = quad;
    }
}

- (void)panGestureChanged:(UIPanGestureRecognizer *)recognizer
{
    UIImageView *view = (UIImageView *)[recognizer view];

    CGPoint translation = [recognizer translationInView:self.view];

    view.centerX += translation.x;
    view.centerY += translation.y;
    [recognizer setTranslation:CGPointZero inView:self.view];

    view.highlighted = recognizer.state == UIGestureRecognizerStateChanged;

    [self createAndApplyQuad];
}

My image call "self.imageViewMaskBald" is inside to other view. I want to make a screenshot of my container view.
Could give an example of how to use the method.

Thank you very much.

I'll send you something this evening

I run this and work fine.

Available in iOS 7.0 and later.

- (UIImage *)snapshot:(UIView *)view
{ 
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, NO, 0.0);
    // Render our snapshot into the image context
    [view drawViewHierarchyInRect:view.bounds afterScreenUpdates:YES];

    // Grab the image from the context
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    // Finish using the context
    UIGraphicsEndImageContext();

    return viewImage;
}

Thank you very much.

Perfect! That is great to know! I didn't know that method existed!
