如何使用AVCapture iOS捕获仅可见图像

Question

I am using AVCapture to capture the images from camera.Everything works fine except this issue.

I need the final captured image as same like which is visible in camera.But the image shows more area(which is not like visible in camera).How can i get the same visible image as final stillImageOutput?

Any help would be highly appreciated.

use your view/imageview object name instead of contentScrollview. This will help you to render the view and provide you an image. for reference: https://charangiri.wordpress.com/2014/09/18/how-to-render-screen-taking-screen-shot-programmatically/

- (UIImage *) createScreenshotOfCompleteScreen
{
UIImage* image = nil;
UIGraphicsBeginImageContext(contentScrollview.contentSize);
{
    CGPoint savedContentOffset = contentScrollview.contentOffset;
    CGRect savedFrame = contentScrollview.frame;
    contentScrollview.contentOffset = CGPointZero;
    contentScrollview.frame = CGRectMake(0, 0, contentScrollview.contentSize.width, contentScrollview.contentSize.height);
    if ([[NSString versionofiOS] intValue]>=7)
    {
        [contentScrollview drawViewHierarchyInRect:contentScrollview.bounds afterScreenUpdates:YES];
    }
    else
    {
        [contentScrollview.layer renderInContext: UIGraphicsGetCurrentContext()];
    }
    image = UIGraphicsGetImageFromCurrentImageContext();
    contentScrollview.contentOffset = savedContentOffset;
    contentScrollview.frame = savedFrame;
}
UIGraphicsEndImageContext();
return image;
}
