myths-Mac:~ myth$ react-native init SqliteApp

To run your app on iOS:
cd /Users/myth/SqliteApp
react-native run-ios
- or -
Open ios/SqliteApp.xcodeproj in Xcode
Hit the Run button
To run your app on Android:
cd /Users/myth/SqliteApp
Have an Android emulator running (quickest way to get started),or a device connected
react-native run-android

How to use (iOS):

# Xcode 8 + 9
myths-Mac:~ myth$ sudo gem install cocoapods

myths-Mac:~ myth$ cd /Users/myth/SqliteApp && yarn add react-native-sqlite-storage

myths-Mac:~ myth$ cd /Users/myth/SqliteApp && ls

App.js android gen ios package.json
__tests__ app.json index.js node_modules yarn.lock

myths-Mac:~ myth$ cd /Users/myth/SqliteApp/ios && ls
SqliteApp SqliteApp-tvOSTests SqliteAppTests
SqliteApp-tvOS SqliteApp.xcodeproj

myths-Mac:~ myth$ cd /Users/myth/SqliteApp/ios && pod init && ls
Podfile SqliteApp-tvOS SqliteApp.xcodeproj
SqliteApp SqliteApp-tvOSTests SqliteAppTests

myths-Mac:~ myth$ cat /Users/myth/SqliteApp/ios/Podfile
# Uncomment the next line to define a global platform for your project
# platform :ios,'9.0'

target 'SqliteApp' do
# Uncomment the next line if you're using Swift or would like to use dynamic frameworks
# use_frameworks!

# Pods for SqliteApp

target 'SqliteApp-tvOSTests' do
inherit! :search_paths
# Pods for testing
end

target 'SqliteAppTests' do
inherit! :search_paths
# Pods for testing
end

end

target 'SqliteApp-tvOS' do
# Uncomment the next line if you're using Swift or would like to use dynamic frameworks
# use_frameworks!

# Pods for SqliteApp-tvOS

target 'SqliteApp-tvOSTests' do
inherit! :search_paths
# Pods for testing
end

end
myths-Mac:~ myth$

上面的命令如何退出呢？先按回车键换行，然后按键盘组合键 Ctrl + D 结束Podfile文件内容写入，我非常喜欢这样去新建或者编辑文件的内容 整个背景色标识的一大块内容只是一条指令哦 在这方面，苹果终端命令与Linux终端命令的玩法一模一样

myths-Mac:~ myth$ cd /Users/myth/SqliteApp/ios && pod install

myths-Mac:~ myth$ cd /Users/myth/SqliteApp && rnpm link
rnpm-link info Linking react-native-sqlite-storage ios dependency
rnpm-link info iOS module react-native-sqlite-storage has been successfully linked

接下来讲如何创建 www 目录并且在终端中如何使用命令创建Sqlite数据表

myths-Mac:~ myth$ cd /Users/myth/SqliteApp/ios/SqliteApp/www && sqlite3 petshop.db
SQLite version 3.16.0 2016-11-04 19:09:39
Enter ".help" for usage hints.
sqlite> create table pet(owner text primary key,petname text not null);
sqlite> insert into pet(owner,petname) values('Tom','Dog');
sqlite> select * from pet;
Tom | Dog
Jason | Cat
sqlite> .exit

现在即使不写任何新代码，使用新建项目中默认的App.js文件代码 执行react-native run-ios会报告上面的错误
