通过命令行控制模拟器--simctl

2018-07-13

要想实现命令行控制模拟器需要用的到命令是simctl: Simulators Control 看这命令的意思像是这两个单词的缩写，搭载xcrun命令，可以通过这个命令实现以下功能

创建、删除、开启模拟器
添加图片到模拟器
安装、卸载、打开、关闭APP

帮助命令

1	xcrun simctl --help

查看当前有哪些模拟器

1	xcrun simctl list

截取部分日志如下

搭载查找命令grep可以查看正在使用的模拟器

1 2	➜ ~ xcrun simctl list \| grep Booted iPhone 6s (26A06303-C684-46F1-AF9B-9ECEB737B2AA) (Booted)

添加一个模拟器

设备名称、设备类型、设备的操作系统、可以定位出一个设备信息，比如我们要增加一个名为DemoDevice、iPhone 7、iOS 11.4命令如下

1 2	➜ ~ xcrun simctl create DemoDevice com.apple.CoreSimulator.SimDeviceType.iPhone-7 com.apple.CoreSimulator.SimRuntime.iOS-11-4 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0

创建成果的话会返回设备的id这里是4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0

list下

-- iOS 11.4 --

    DemoDevice (4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0) (Shutdown)

也可以通过grep搜索一下

➜  ~ xcrun simctl list | grep  4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0
    DemoDevice (4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0) (Shutdown)

开启一个模拟器

以刚才那个自己创建的为例子吧

1	➜ ~ xcrun simctl boot 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0

写个图片到刚才的模拟器中

桌面准备一张图片`google@2x.png`

1	➜ ~ xcrun simctl addmedia 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0 ~/Desktop/google@2x.png

打开相册会发现多了一张图片，就不截图了

重置模拟器

重置模拟器的命令

1	➜ ~ xcrun simctl erase 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0

如果你的模拟器已经开启的情况下可能会报下面的错误

1 2	An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=164): Unable to erase contents and settings in current state: Booted

提示你的模拟器当前的状态是booted的，所有要先关掉模拟器

1	➜ ~ xcrun simctl shutdown 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0

再执行

1	➜ ~ xcrun simctl erase 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0

会发现之前的所有的修改都没了

如果发现设备卡住了，可以关掉再重新boot下

通过DerivedData来安装app

（1）在桌面下新建一个名为TestSimctl的工程

（2）cd到TestSimctl目录下通过build命令来得到DerivedData路径

1	xcodebuild build -scheme 'TestSimctl' CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO -sdk iphonesimulator11.4

会得到~/Library/Developer/Xcode/DerivedData/TestSimctl-heyedthdtyuorceyxhlduzjcoqol/Build/Products/Debug-iphonesimulator/TestSimctl.app
每个人的机器路径会有些不一样复制一下就好了

（2）通过刚才的DerivedData来安装TestSimctl应用

1	xcrun simctl install booted ~/Library/Developer/Xcode/DerivedData/TestSimctl-heyedthdtyuorceyxhlduzjcoqol/Build/Products/Debug-iphoneos/TestSimctl.app

（3）通过bundleid来卸载刚才那个app，我这里是com.TestSimctl

1	xcrun simctl uninstall booted com.TestSimctl

发现哪个app不见了

（4）通过bundleid来启动刚才app, 先保证已经安装了app

1	xcrun simctl launch booted com.TestSimctl

会发现已经启动起来了

（4）通过bundleid来关闭已经打开的app

1	xcrun simctl terminate booted com.TestSimctl

截图功能

3

➜  TestSimctl git:(master) ✗ xcrun simctl io booted screenshot test.png
Detected file type 'PNG' from extension
Wrote screenshot to: test.png

会发现当前目录下多了一张照片

1	└── test.png

日志功能

1	xcrun simctl spawn booted log stream --predicate 'processImagePath endswith "TestSimctl"'

改造下viewcontroller代码

3

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    NSLog(@"touchesBegan");
}

重新build后可以发现终端可以看到日志了

删除模拟器

先shutdown

1	xcrun simctl shutdown 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0

再删除

1	xcrun simctl delete 4F5A92A2-8241-4A8E-8A22-2E5A87FECCC0
