Hi everyone,

I have a scroll view containing (among others) subviews with SciChart surfaces. I use this method:

 [self.scrollView.layer renderInContext:UIGraphicsGetCurrentContext()];

… to take a screenshot of the whole scroll view (render it as a UIImage). All charts are rendered as black rectangles. Same thing happens if I use “Capture view hierarchy” in XCode – black rectangles where there should be a chart.

Any ideas?

You can try following method to capture the SciChart view

- (UIImage *)screenShort {

CGRect rect = [self bounds];

UIGraphicsBeginImageContext(CGSizeMake(rect.size.width*[UIScreen mainScreen].scale, rect.size.height*[UIScreen mainScreen].scale));

[self drawViewHierarchyInRect:CGRectMake(.0f, .0f, rect.size.width*[UIScreen mainScreen].scale, rect.size.height*[UIScreen mainScreen].scale) afterScreenUpdates:YES];

UIImage *img = UIGraphicsGetImageFromCurrentImageContext();


return img;
