[Code Note] Two Methods of transmitting JSON data to the server: json

I. Code.

-(Void) viewDidLoad {[super viewDidLoad]; // Do any additional setup after loading the view. // The first method is to combine the parameters to be passed into an array, and then convert the dictionary into a string NSDictionary * jsonDic = [NSDictionary dictionaryWithObjectsAndKeys: @ "Li Hua ", @ "name", @ "", @ "sex", @ "20", @ "age", nil]; NSString * jsonString = [jsonDic JSONString]; NSLog (@ "--- jsonString ---- % @", jsonString); // The second method is to directly combine strings in the json format. This method is applicable when there are special requirements on the order of parameters. Otherwise, it looks a little complicated. NSString * jsonStringOther = [NSString stringWithFormat: @ "{\" name \ ": \" % @ \ ", \" sex \ ": \" female \", \ "age \": \ "20 \"} ", @" Li Hua "]; NSLog (@" ----- jsonStringOther --- % @ ", jsonStringOther );}
