swift--load the local resource file and traverse

To get started with Swift, the previous OC was a weak language, and Swift was a strong language, with a big difference in syntax.

//JSON file[ {    "name":"Json1",    "title":"Test 1", }, {     "name":"Json2",     "title":"Test 2", }, {     "name":"Json3",     "title":"Test 3", } ]

        /** Loading local files*/                //1. Get the file pathLet path = Nsbundle.mainbundle (). Pathforresource ("Plist.json", Oftype:nil)//2. Create a nsdata from a file path        ifLet JsonPath =path {let Jsondata=NSData (Contentsoffile:jsonpath)//a method with throws needs to throw an exception             Do {                /** There is a possibility that the exception code is placed in this*/                //3. Serialization of data---array                /** The difference between try and try! * Try exception will jump to catch code * try!

Iterating through an array//To iterate through an array in swift, you must make it clear that the type of the data [[string:string]] means that the key value in the dictionary is a string [[String]] indicating that the array is all strings                 forDictinchDictarr as![[string:string]] {print (dict)}}Catch {                //The exception code is placed hereprint (Error)}}
