我现在的类有大约50行只是编码和解码变量,以便我的类与NSUserDefaults兼容。有没有更好的方法来处理这个问题?有没有比NSCoder编码和解码所有东西更好的方式来保存自定义类到NSUserDefaults?
例子:
init(coder aDecoder: NSCoder!) {
lightEnabled = aDecoder.decodeBoolForKey("lightEnabled")
soundEnabled = aDecoder.decodeBoolForKey("soundEnabled")
vibrateEnabled = aDecoder.decodeBoolForKey("vibrateEnabled")
pulseEnabled = aDecoder.decodeBoolForKey("pulseEnabled")
songs = aDecoder.decodeObjectForKey("songs") as! [Song]
currentSong = aDecoder.decodeIntegerForKey("currentSong")
enableBackgroundSound = aDecoder.decodeBoolForKey("enableBackgroundSound")
mixSound = aDecoder.decodeBoolForKey("mixSound")
playSoundInBackground = aDecoder.decodeBoolForKey("playSoundInBackground")
duckSounds = aDecoder.decodeBoolForKey("duckSounds")
BPMBackground = NSKeyedUnarchiver.unarchiveObjectWithData(aDecoder.decodeObjectForKey("BPMBackgorund") as! NSData) as! UIColor!
BPMPulseColor = NSKeyedUnarchiver.unarchiveObjectWithData(aDecoder.decodeObjectForKey("BPMPulseColor") as! NSData) as! UIColor!
TempoBackGround = NSKeyedUnarchiver.unarchiveObjectWithData(aDecoder.decodeObjectForKey("TempoBackGround") as! NSData) as! UIColor!
TempoPulseColor = NSKeyedUnarchiver.unarchiveObjectWithData(aDecoder.decodeObjectForKey("TempoPulseColor") as! NSData) as! UIColor!
TimeBackGround = NSKeyedUnarchiver.unarchiveObjectWithData(aDecoder.decodeObjectForKey("TimeBackGround") as! NSData) as! UIColor!
TimeStrokeColor = NSKeyedUnarchiver.unarchiveObjectWithData(aDecoder.decodeObjectForKey("TimeStrokeColor") as! NSData) as! UIColor!
TextColor = NSKeyedUnarchiver.unarchiveObjectWithData(aDecoder.decodeObjectForKey("TextColor") as! NSData) as! UIColor!
}
func encodeWithCoder(aCoder: NSCoder!) {
aCoder.encodeBool(lightEnabled, forKey: "lightEnabled")
aCoder.encodeBool(soundEnabled, forKey: "soundEnabled")
aCoder.encodeBool(vibrateEnabled, forKey: "vibrateEnabled")
aCoder.encodeBool(pulseEnabled, forKey: "pulseEnabled")
aCoder.encodeObject(songs, forKey: "songs")
aCoder.encodeInteger(currentSong, forKey: "currentSong")
aCoder.encodeBool(enableBackgroundSound, forKey: "enableBackgroundSound")
aCoder.encodeBool(mixSound, forKey: "mixSound")
aCoder.encodeBool(playSoundInBackground, forKey: "playSoundInBackground")
aCoder.encodeBool(duckSounds, forKey: "duckSounds")
aCoder.encodeObject(BPMBackground.archivedData(), forKey: "BPMBackground")
aCoder.encodeObject(BPMPulseColor.archivedData(), forKey: "BPMPulseColor")
aCoder.encodeObject(TempoBackGround.archivedData(), forKey: "TempoBackGround")
aCoder.encodeObject(TempoPulseColor.archivedData(), forKey: "TempoPulseColor")
aCoder.encodeObject(TimeBackGround.archivedData(), forKey: "TimeBackGround")
aCoder.encodeObject(TimeStrokeColor.archivedData(), forKey: "TimeStrokeColor")
aCoder.encodeObject(TextColor.archivedData(), forKey: "TextColor")
}
你见过尼克洛克伍德的https://github.com/nicklockwood/FastCoding吗? – Shripada
如果你很好奇,我会用最近刚开始做的一件小事来稍微更新我的答案。在我的回答结束时检查更新的位。我相信它会改善你的代码甚至模式。 – crashoverride777
嘿,请再次阅读我的答案,主要是有关解码器方法的部分。我注意到那里有一个错误。我没有考虑到您可能会向SettingsDict添加新值,而不是在下次应用启动时将这些值删除,因为整个字典会被保存的字典所取代。我现在只用保存的数据更新字典。这应该会使它在未来更加灵活。 – crashoverride777
