我正在使用ExtensionDelegate，因此可以从自己的evnts(最终是InterfaceController)访问ComplicationController变量。
当我从evnts 中获取数据时，我需要刷新ExtensionDelegate中的WCSession, didReceiveUserInfo，但是无法弄清楚怎么做，有什么想法吗？
原因是:evnts为空，因为它在WCSession, didReceiveUserInfo运行以实际获取数据之前被调用。
(任何问题都让我知道，并将根据需要发布任何额外的代码!)
ExtensionDelegate:class ExtensionDelegate: NSObject, WKExtensionDelegate {
var evnts = [Evnt]()
}
InterfaceController:func session(session: WCSession, didReceiveUserInfo userInfo: [String : AnyObject]) {
if let tColorValue = userInfo["TeamColor"] as? String, let matchValue = userInfo["Matchup"] as? String {
let myDelegate = WKExtension.sharedExtension().delegate as! ExtensionDelegate
var extEvnts = myDelegate.evnts
receivedData.append(["TeamColor" : tColorValue , "Matchup" : matchValue])
extEvnts.append(Evnt(dataDictionary: ["TeamColor" : tColorValue , "Matchup" : matchValue]))
doTable()
} else {
print("tColorValue and matchValue are not same as dictionary value")
}
}
func doTable() {
let myDelegate = WKExtension.sharedExtension().delegate as! ExtensionDelegate
let extEvnts = myDelegate.evnts
self.rowTable.setNumberOfRows(extEvnts.count, withRowType: "rows")
for (index, evt) in extEvnts.enumerate() {
if let row = rowTable.rowControllerAtIndex(index) as? TableRowController {
row.mLabel.setText(evt.eventMatch)
row.cGroup.setBackgroundColor(colorWithHexString(evt.eventTColor))
} else {
print("nope")
}
}
}
最佳答案
您可以将evnts中的ExtensionDelegate设为静态变量
class ExtensionDelegate: NSObject, WKExtensionDelegate {
static var evnts = [Evnt]()
}
然后，您还需要进行更改:
func session(session: WCSession, didReceiveUserInfo userInfo: [String : AnyObject]) {
if let tColorValue = userInfo["TeamColor"] as? String, let matchValue = userInfo["Matchup"] as? String {
receivedData.append(["TeamColor" : tColorValue , "Matchup" : matchValue])
ExtensionDelegate.evnts.append(Evnt(dataDictionary: ["TeamColor" : tColorValue , "Matchup" : matchValue]))
doTable()
} else {
print("tColorValue and matchValue are not same as dictionary value")
}
}
和
func doTable() {
let extEvnts = ExtensionDelegate.evnts
self.rowTable.setNumberOfRows(extEvnts.count, withRowType: "rows")
for (index, evt) in extEvnts.enumerate() {
if let row = rowTable.rowControllerAtIndex(index) as? TableRowController {
row.mLabel.setText(evt.eventMatch)
row.cGroup.setBackgroundColor(colorWithHexString(evt.eventTColor))
} else {
print("nope")
}
}
}
