I have a PDF file in my DocumentDirectory
.
I want the user to be able to rename this PDF file to something else if they choose to.
I will have a UIButton
to start this process. The new name will come from a UITextField
.
How do I do this? I'm new to Swift and have only found Objective-C info on this and am having a hard time converting it.
An example of the file location is:
/var/mobile/Containers/Data/Application/39E030E3-6DA1-45FF-BF93-6068B3BDCE89/Documents/Restaurant.pdf
I have this code to see check if the file exists or not:
var name = selectedItem.adjustedName
// Search path for file name specified and assign to variable
let getPDFPath = paths.stringByAppendingPathComponent("\(name).pdf")
let checkValidation = NSFileManager.defaultManager()
// If it exists, delete it, otherwise print error to log
if (checkValidation.fileExistsAtPath(getPDFPath)) {
print("FILE AVAILABLE: \(name).pdf")
} else {
print("FILE NOT AVAILABLE: \(name).pdf")
}
To rename a file you can use NSFileManager's moveItemAtURL
.
Moving the file with moveItemAtURL
at the same location but with two different file names is the same operation as "renaming".
Simple example:
Swift 2
do {
let path = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let documentDirectory = NSURL(fileURLWithPath: path)
let originPath = documentDirectory.URLByAppendingPathComponent("currentname.pdf")
let destinationPath = documentDirectory.URLByAppendingPathComponent("newname.pdf")
try NSFileManager.defaultManager().moveItemAtURL(originPath, toURL: destinationPath)
} catch let error as NSError {
print(error)
}
Swift 3
do {
let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
let documentDirectory = URL(fileURLWithPath: path)
let originPath = documentDirectory.appendingPathComponent("currentname.pdf")
let destinationPath = documentDirectory.appendingPathComponent("newname.pdf")
try FileManager.default.moveItem(at: originPath, to: destinationPath)
} catch {
print(error)
}
