transferCurrentComplicationUserInfo 更适合复杂度更新吗? [英] Is transferCurrentComplicationUserInfo more suitable for complication update?

问题描述

transferCurrentComplicationUserInfo 和 transferUserInfo 有什么区别?

我想将数据从我的 AppDelegate 发送到时钟套件并发症.

I want to send data from my AppDelegate to a clock kit complication.

transferCurrentComplicationUserInfo 似乎与 transferCurrentUserInfo 做的事情完全一样.我错过了什么吗?

transferCurrentComplicationUserInfo seems to do exactly the same thing as transferCurrentUserInfo. Am I missing something?

推荐答案

这两者的区别WCSession 方法涉及数据何时发送，watchkit 扩展是否被唤醒.

The distinction between these two WCSession methods involve when the data is sent, and whether the watchkit extension is woken up or not.

transferCurrentComplicationUserInfo: 专门用于传输要立即显示在表盘上的复杂用户信息.

transferCurrentComplicationUserInfo: is specifically designed for transferring complication user info meant to be shown on the watch face right now.

• 并发症用户信息被标记为紧急"，并被放置在队列的前面，
• 手表在后台唤醒扩展程序以接收信息，并且
• 转移会立即发生.(其他排队的信息也可能在那时传输.)

transferUserInfo: 排队信息，当系统确定是处理队列的好时机时传输:

transferUserInfo: queues up information, to be transferred when the system determines it's a good time to process the queue:

• 用户信息放在队列的后面，
• 如果分机未唤醒，则存储传输的信息，
• 转移不会立即发生，并且
• 信息按发送顺序发送.

iOS 10 更新:

在 iOS 10 中，WCSession 添加了一个 remainingComplicationUserInfoTransfers 属性会影响 iOS 将使用哪种方法传输用户信息:

In iOS 10, WCSession adds a remainingComplicationUserInfoTransfers property which can affect which method that iOS will use to transfer the user info:

当天可以调用transferCurrentComplicationUserInfo:的剩余次数.如果此属性设置为 0，则对 transferCurrentComplicationUserInfo: 的任何其他调用都使用 transferUserInfo: 代替.

The number of remaining times that you can call transferCurrentComplicationUserInfo: during the current day. If this property is set to 0, any additional calls to transferCurrentComplicationUserInfo: use transferUserInfo: instead.

如果复杂功能出现在活跃的表盘上，您每天可以进行 50 次传输.如果复杂功能未激活，则此属性默认为 0.

If the complication is on the active watch face, you are given 50 transfers a day. If the complication is not active, this property defaults to 0.
