我刚刚从beta 3进入了
Xcode 8 beta 4,但出于任何原因我得到的这个错误没有错误或直到测试版4发出.这里是错误“类型’FileManager’的值没有成员’urlsForDirectory’ “
我的代码：
func setupRecorder(){
let audioSession:AVAudioSession = AVAudioSession.sharedInstance()
//ask for permission
if (audioSession.responds(to: #selector(AVAudioSession.requestRecordPermission(_:)))) {
AVAudioSession.sharedInstance().requestRecordPermission({(granted: Bool)-> Void in
if granted {
print("Permission Granted\n")
//set category and activate recorder session
do {
//----
let fileManager = FileManager.default
let urls = fileManager.urlsForDirectory(.documentDirectory,inDomains: .userDomainMask)
//----
let documentDirectory = urls[0] as URL
let soundURL = try! documentDirectory.appendingPathComponent("sound.m4a")
try audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord)
try self.soundRecorder = AVAudioRecorder(url: soundURL,settings: self.recordSettings)
let micInput = try AVAudioRecorder(url
: soundURL,settings: self.recordSettings)
self.soundRecorder.prepareToRecord()
self.soundRecorder.updateMeters()
} catch {
print("Error Recording");
}
}
})
}
}
但唯一的部分是这一行：
let urls = fileManager.urlsForDirectory(.documentDirectory,inDomains: .userDomainMask)
“”FileManager’类型的值没有成员’urlsForDirectory’”
解决方法
您只需将其更改为网址(对于:),如下所示：
let documentDirectory = FileManager.default.urls(for: .documentDirectory,in: .userDomainMask).first!
