因此,这可能不完全是您正在寻找的内容,但这就是我捕获用户(用手指/手写笔)绘制的签名的方式。您的 UIImageView 将具有绘制的签名。我没有考虑过如何将签名图像传输到 .xls,但您可以将图像保存到设备的照片库,然后像导出任何其他图像一样将其导出,然后将其放入 .xls(我知道,这是一本手册)过程)。我希望这有帮助。

So, this may not be exactly what you are looking for, but this is how I capture a signature drawn by a user (with their finger/stylus). Your UIImageView will have the drawn signature. I have not thought about how to transfer the signature image to the .xls but you could save the image to the device's photo library then export it like you would any other image, then drop it into the .xls (I know, that's a manual process). I hope this helps.
