iOS
对于 iOS 9.2 及更低版本，苹果唯一的自动化技术被称为UIAutomation，它运行在 Instruments 中。从 iOS 10 开始，苹果已经完全删除了 UIAutomation 工具。
同时，苹果推出了一款名为XCUITest 的新型自动化技术，从 iOS 9.3 到 iOS 10 及以上版本，这将是苹果唯一支持的自动化框架。
【Protobuf】Protocol Buffers 2中使用map
Maps
If you want to create an associative map as part of your data definition, protocol buffers provides a handy shortcut syntax:
map<key_type, value_type> map_field = N;
…where the key_type can be any integral or string type (so, any scalar type except for floating point types and bytes). Note that enum is not a valid key_type. The value_type can be any type except another map.
So, for example, if you wanted to create a map of projects where each Project message is associated with a string key, you could define it like this:
map<string, Project> projects = 3;
The generated map API is currently available for all proto2 supported languages. You can find out more about the map API for your chosen language in the relevant API reference.
