一、Swift-OC混编桥文件

1

2

3

二、Git修改密码报错 remote: Invalid username or password

git config --global user.name "yourname"

git config --global user.email "youremail"

三、把数组保存到plist

存：

let paths = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true)[0]

let plistPath = paths + "/areaForEShop.pist"

let plistUrl = URL.init(fileURLWithPath: plistPath)

array.write(to: plistUrl, atomically: true)

读

读上面存的

let paths = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true)[0]

let plistPath = paths + "/areaForEShop.pist"

let array = NSArray.init(contentsOfFile: plistPath)

直接读取plist文件

let plists = Bundle.main.path(forResource: "areaForEShop", ofType: "plist")!

let resultArray: NSArray =  NSArray.init(contentsOfFile: plists)!

四、CoreData

创建CoreData时，如果移动CoreDataClass.swift和CoreDataProperties.swift时搞错，在 TARGETS->Build Phases->Compile Sources中删掉这两个.swift文件就好了。
