我在转换 Objective-C 代码以创建 Swift 目录时遇到了一些问题。

objective-C :

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/MyFolder"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];

最佳答案

Swift 5.0

let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let documentsDirectory = paths[0]
let docURL = URL(string: documentsDirectory)!
let dataPath = docURL.appendingPathComponent("MyFolder")
if !FileManager.default.fileExists(atPath: dataPath.path) {
do {
try FileManager.default.createDirectory(atPath: dataPath.path, withIntermediateDirectories: true, attributes: nil)
} catch {
print(error.localizedDescription)
}
}

Swift 4.0

let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentsDirectory: AnyObject = paths[0] as AnyObject
let dataPath = documentsDirectory.appendingPathComponent("MyFolder")!

do {
try FileManager.default.createDirectory(atPath: dataPath.absoluteString, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
print(error.localizedDescription)
}

Swift 3.0

let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentsDirectory: AnyObject = paths[0]
let dataPath = documentsDirectory.appendingPathComponent("MyFolder")!

do {
try FileManager.default.createDirectory(atPath: dataPath.absoluteString, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
print(error.localizedDescription)
}

swift 2.1

您可以使用以下方法创建目录:

let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)
let documentsDirectory: AnyObject = paths[0]
let dataPath = documentsDirectory.stringByAppendingPathComponent("MyFolder")

do {
try NSFileManager.defaultManager().createDirectoryAtPath(dataPath, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
print(error.localizedDescription)
}
