, and the constraints of the layout system, complex animations, especially UIView series or CALayer series of animations, are not possible. The only thing that seems possible now is frame animation, which WKInterfaceImage can be achieved by setting up an image with more than one image, or replacing an image with a timer timing. While Apple's own example has been animated in this way, the storage and power consumption of the device can be challenging, and it needs to be tested and observed after

be really need to strengthen AH. Take a look at the other two map apps, one is Uber and the other is Apple's own map.Yes, Uber also has AW's app, and I've used it to call a few times, and I feel that the map function in Uber is now more powerful than the map function of the graph trader.Apple official Map app:As you can see, Uber, as a third party, can not only complete the core call function, but also show the map on the watch, although the map cann

. WatchKit does not support the setting of frame, currently I know, just support in the landscape "left and right", on the vertical "upper and lower", support set size. If you want to implement a nine Gongge style page, compare flattering by using a three row table row Controller, three buttons per line. Not flattering method, sorry, I found that regardless of the arrangement of these properties, can not come out nine Gongge.3, in the session page dis

This article is mainly about how to write pages on Apple Watch.You need to work in the "Emwatchocdemo WatchKit App" in the project, the structure of the folderWatchKit almost not allow direct coding page, can only drag on the storyboard, and for me this habit directly coding page of people, really very painful.1.

Communicating between the IOS app and the Watch ExtensionThere is four scenarios, where an app and a extension might wish to communicate: Watch extension to suspended/terminated IOS app-use +[wkinterfacedevice openparentapplication:reply:] If you NE Ed to ' Wake up ' your IOS app. If you simply need to leave data in a place for your IOS apps to find it later and then you should write it into the shared

Opencv experiences (1) The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image proce
