在iOS9之前,我们创建了一个类似的目录

let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as! String
let logsPath = documentsPath.stringByAppendingPathComponent("logs")
let errorPointer = NSErrorPointer()
NSFileManager.defaultManager().createDirectoryAtPath(logsPath, withIntermediateDirectories: true, attributes: nil, error: errorPointer)

但是对于iOS9,他们删除了String.stringByAppendingPathComponent.自动转换工具取代了我们对NSURL使用String.createDirectoryAtPath()接受一个字符串,所以我需要将NSURL转换为字符串.我们像这样使用absolutePath :(更新为iOS9)

let documentsPath = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0])
let logsPath = documentsPath.URLByAppendingPathComponent("logs")
do {
    try NSFileManager.defaultManager().createDirectoryAtPath(logsPath.absoluteString, withIntermediateDirectories: true, attributes: nil)
} catch let error as NSError {
    NSLog("Unable to create directory \(error.debugDescription)")
}

但是我收到以下错误:
