Ios WatchKit数据未显示
我正在将数据从iOS传递到WatchKit我无法获得数据来显示在WatchKit端接收到的数据 这工作正常:iOSIos WatchKit数据未显示,ios,swift,watchkit,watchos-2,Ios,Swift,Watchkit,Watchos 2,我正在将数据从iOS传递到WatchKit我无法获得数据来显示在WatchKit端接收到的数据 这工作正常:iOSTableViewController func getCloudKit() { ///... let publicData = container.publicCloudDatabase publicData.performQuery(query, inZoneWithID: nil) { results, error in if error

这不会调用任何NSLog
s或显示任何数据:WatchKitInterfaceController

print(error)

有什么想法吗?谢谢 尝试使用以下内容检查会话是否为零(我的swift foo很弱):
什么是WatchSessionManager,它是否确保设置并激活WCSession?
WatchSessionManager
是一个设置并激活WCSession的单例类。这是在iOS端,所以当我记录所有内容时,这一部分工作得非常完美。手表套件的一面不太好用。有什么想法吗?会话在configureWCSession()中可能为零吗?嗯,可能吧,你如何再检查一下?我做了打印(“会话:\(会话)”)
并且它给了我`session:Optional()`所以我想你是对的?嗯。。。尝试在调用activateSession之后添加打印(“会话…”。然后打印什么?是的,它在activateSession()
之后工作::“session:Optional()”在手表端是session.reachable true?applicationContext不需要它,但可能会提供一个类似于true的ClueLook。如果(session?.reachable!=nil),我这样做了if(session?.reachable!=nil){NSLog(“Yes”)}
它NSLog
ged“Yes”。
