I am getting error when trying to use pasteboard method to post images through input control of the custom keyboard I am following this tutorial [question]: iOS: Custom keyboard: I want to send images to the textDocumentProxy(Input controls) , but I am getting error when trying to send the image with above error of the title that I stated I really hoped some of you guys can help me out.

-(void)keyBoardButtonClick:(UIButton *)sender

    {

    //    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

        if (sender.tag==1111) {
            [self.textDocumentProxy insertText:@"⒜⒝⒞⒟Ψ"];
            NSData *imgData = UIImagePNGRepresentation(@"apple.png");

            if(imgData == nil){
                NSLog(@"error image");
            }else{
                NSLog(@"true image");
            }


            NSLog(@"pressed 1");

        }

Show the whole error message, there should be more about the NSException. But `UIImagePNGRepresentation();` expects a `UIImage` object as parameter, not a `NSString`. – Larme Feb 17 '17 at 14:46
you mean UIImagePNGRepresentation() I should change to UIImage? – user3711175 Feb 17 '17 at 14:51
Hi @Larme u there? – user3711175 Feb 17 '17 at 14:59

The official Doc `NSData * UIImagePNGRepresentation(UIImage *image);`. The doc as you are coding it : `NSData * UIImagePNGRepresentation(NSString *imageName);` (which is invented). So `NSData *imgData = UIImagePNGRepresentation([UIImage imageNamed:@"apple.png"]);` maybe? And you still didn't post more about that crash log you got about that NSException. – Larme Feb 17 '17 at 15:01
Thanks @Larme it works you are the best! – user3711175 Feb 17 '17 at 15:06
Didn't Xcode throw a warning `"Incompatible pointer types passing 'NSString *' to parameter of type 'UIImage * _Nonnull'"` for that line? – Larme Feb 17 '17 at 15:08
No it didnt.... – user3711175 Feb 17 '17 at 15:12
Hi @Larme one more thing after adding the image file apple.png in my file I got nsexception error again can I know what is wrong again? – user3711175 Feb 17 '17 at 15:24
Again, give the complete error message! – Larme Feb 17 '17 at 16:06
