Get Button Image File Name in Swift
提问by plumwd
Currently have a button with an embedded image. I'd like to get the image name of the button so that I can create a UIImage with it for sharing when the user clicks the button.
目前有一个带有嵌入图像的按钮。我想获取按钮的图像名称，以便在用户单击按钮时可以使用它创建一个 UIImage 以进行共享。
I've tried a variety of methods including
我尝试了多种方法，包括
let imagename = sender.currentImage
let image = UIImage(name: imagename)
This results in error "Missing argument for parameter 'inBundle' in call
这会导致错误“在调用中缺少参数‘inBundle’的参数
Looking for some guidance on how to proceed. I am going to have many buttons similar to this one and would rather build a function than individual actions for each button.
寻找有关如何进行的一些指导。我将有许多与此类似的按钮，并且宁愿为每个按钮构建一个功能而不是单独的操作。

Get the image name you have assigned to your UIButton:
获取分配给 UIButton 的图像名称：
let createdButton = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
createdButton.setImage(UIImage(named: "Image_Assigned"), for: .normal)
checkButtonName(yourButton: createdButton)
func checkButtonName(yourButton: UIButton) {
if yourButton.currentImage == UIImage(named: "Image_Assigned") {
print("IMAGE NAME IS Image_Assigned")
}
else {
print("IMAGE NAME IS NOT Image_Assigned")
}
}

You can reuse the image using your first line:
您可以使用第一行重复使用图像：
let image = sender.currentImage
让图像 = sender.currentImage
