CaptureImage(ScreenShot Of View).

This Code Useful when user wants to capture current view ScreenShot and share or save this image....

- (UIImage *)captureView {

//hide controls if needed

CGRect rect = [self.view bounds];

    

    UIGraphicsBeginImageContext(rect.size);

    CGContextRef context = UIGraphicsGetCurrentContext();

    [self.view.layer renderInContext:context];   

    UIImage *img = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return img;

}

If the view contains the layer images or some graphics related data then use below method.

-(UIImage *)convertViewToImage:(UIView *)viewTemp

{

    UIGraphicsBeginImageContext(viewTemp.bounds.size);

    [viewTemp drawViewHierarchyInRect:viewTemp.bounds afterScreenUpdates:YES];

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    

    return image;

}
