您无法通过uitextdocumentproxy发送图片

在自定义键盘中，您必须在粘贴板中复制图像，然后使用以下代码手动粘贴到文本字段中：

NSString *shareImageName = @"cross.png";
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
UIImage *image = [UIImage imageNamed:shareImageName];
NSData *data = UIImagePNGRepresentation(image);
[pasteboard setData:data forPasteboardType:@"public.png"];
