推荐答案
是的,你必须将其转换为Data,然后将其保存到设备上的文档目录中.像这样的功能会起作用:
Yes, you have to convert it to Data and then save it to the documents directory on the device. A function like this would work:
func saveBase64StringToPDF(_ base64String: String) {
guard
var documentsURL = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)).last,
let convertedData = Data(base64Encoded: base64String)
else {
//handle error when getting documents URL
return
}
//name your file however you prefer
documentsURL.appendPathComponent("yourFileName.pdf")
do {
try convertedData.write(to: documentsURL)
} catch {
//handle write error here
}
//if you want to get a quick output of where your
//file was saved from the simulator on your machine
//just print the documentsURL and go there in Finder
print(documentsURL)
}
