WatchOS2 的调试建议
Debugging advice for WatchOS2
我一直在浏览 RayWenderlich 团队编写的 WatchOS 2 By Tutorial 书中的示例，特别是第 18 章。它们都运行良好。在我自己的应用程序中，我试图从手表发送按钮按下以触发 iPhone 应用程序上的按钮。这是 Watch 和 Phone 中 Swift 中的相关代码：

以及接收码
iPhone:CODE:

didReceiveMessage message: [String : AnyObject],
replyHandler: ([String : AnyObject]) -> Void) {
if let counterd = message["add"] as? Float {
let reply = ["add":counterd]
print("iPhone Receive Add \(counterd)")
addButtonPressed(self)
replyHandler(reply)
}
if let counterd = message["minus"] as? Float {
let reply = ["minus":counterd]
print("iPhone Receive minus \(counterd)")
removeButtonPressed(self)
replyHandler(reply)
}
if let status = message["status"] as? String {
if status == "Start" {
let reply = ["status":"Quorum"]
meetingStartedButtonPressed(self)
replyHandler(reply)
}
if status == "Quorum" {
let reply = ["status": "Finish"]
quorumButtonPressed(self)
replyHandler(reply)
}
if status == "Finish" {
let reply = ["status": "Reset"]
meetingEndedButtonPressed(self)
replyHandler(reply)
}
if status == "Reset" {
let reply = ["status": "Start"]
resetButtonPressed(self)
replyHandler(reply)
}
print("iPhone Received Status Button \(status)")
}
}
我在 Watch 上收到消息并在调试日志中看到它们...但它们似乎没有在 Phone 上触发。 phone 已成功将其消息发送到手表。
我已经在模拟器和我自己的手表上以及 iPhone 上测试了这段代码。请注意，从 iPhone 到 Watch 的消息是使用 via updateApplicationContext 完成的，而我尝试使用发送消息将消息从手表发送到 iPhone。这是用于发送上下文的 iPhone 代码示例：
if WCSession.isSupported() {
if session.watchAppInstalled {
let UserInfo = ["waste":Float((wastedAmount.text! as NSString).floatValue), "cost":Float((totalAmount.text! as NSString).floatValue), "counter":Float((peopleInMeeting.text! as NSString).floatValue), "status":"Start"]
do {
try session.updateApplicationContext(UserInfo as! [String : AnyObject])
} catch {
print("Updating the context failed: ")
}
}
}
当您说：
时，需要更多关于您在手表上实际看到的具体信息
I get the messages firing fine on the Watch and see them in the debug log... But they do not seem to fire on the Phone. The phone is successfully sending its messages to the watch.
然而，一种常见的情况是 iPhone 代码实际上工作正常，您唯一看不到的是打印到控制台的调试语句。这似乎是这种情况，因为您说您看到了预期的 Watch 消息，大概包括来自 print("Reply: \(reply)") 的消息。这表示消息正在由 iPhone.
处理
在这种情况下，通常只是因为您希望同时看到来自 Watch 和 iOS 模拟器进程的调试控制台消息，但实际上您只连接到一个或另一个。您可以（至少）在这里做两件事：
- 运行 来自 Xcode 的 WatchKit 应用程序，但随后更改为附加到 iPhone 进程。在 Xcode 中，转到
Debug > Attach to Process... 和 select "Likely Targets" 下的 iPhone 应用程序。
- 首先 运行安装 iPhone 应用程序，这意味着您已经连接到该进程。在 Apple Watch 模拟器中，运行 Watch 应用程序。然后您将能够调试通信的 iPhone 端。
在 Watch-OS 中调试，而在 运行 iPhone 应用程序中调试，在 Xcode-8.1 中反之亦然。必需 运行 需要附加进程 。
