How do I encode enum using NSCoder in swift?3个
我有
我有
var priority : Priority! = Priority.defaultPriority
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeInteger(priority.toRaw(),forKey: "priority") //toRaw may not yield the result I am expecting
}
required init(coder aDecoder: NSCoder) {
priority = aDecoder.decodeIntegerForKey("priority") //complaining about conflicting types
}
枚举如下：
enum Priority : Int {
case defaultPriority = 0
case lowPriority = 1
case mediumPriority = 2
case highPriority = 3
}
编码/解码这个的最佳方法是什么？
解决方法
Priority.init(rawValue :)应该可以工作.
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeInteger(priority.rawValue,forKey: "priority")
}
required init(coder aDecoder: NSCoder) {
priority = Priority(rawValue: aDecoder.decodeIntegerForKey("priority"))
}
