  1，不浪费时间，本代码经实践检验通过！

    //网络请求代码段

    //post  request

    NSURL *url=[NSURL

URLWithString:@"http://192.168.253.101:8080/ERP/mobile/login.action"];

    NSMutableURLRequest *request =[[NSMutableURLRequest

alloc]initWithURL:url

cachePolicy:NSURLRequestUseProtocolCachePolicy

timeoutInterval:10];

    //设置请求方式

    [request

setHTTPMethod:@"POST"];

    //设置参数

    NSString *str=@"username=A023&password=1&master=UAS";

    NSData *data=[str

dataUsingEncoding:NSUTF8StringEncoding];

setHTTPBody:data];

    //连接服务器

    NSData *received=[NSURLConnection

sendSynchronousRequest:request returningResponse:nil

error:nil];

    NSString *strl=[[NSString

alloc]initWithData:received

encoding:NSUTF8StringEncoding];

    // NSLog(@"结果：%@",strl); －－－自定义json 格式字符串  包含集合和数组形式  采用原生类库解析的方式

NSError *error;

    NSString *temstr=@"{\"count\":50,\"allprocess\":[{\"name\":\"神圣天使\"},{\"name\":\"商品天使\"},{\"name\":\"美丽天使\"}]}";

NSLog(@"temstr=%@",temstr);

    NSData *rdata=[temstr

NSLog(@"rdata=%@",rdata);

    NSDictionary *json=[temstr

objectFromJSONStringWithParseOptions:JKParseOptionLooseUnicode];

NSLog(@"json=%@",json);

NSArray *elist=[json

objectForKey:@"allprocess"];

NSString *uu=[elist

objectAtIndex:1];

NSString *u_name=[[elist

objectAtIndex:1]

objectForKey:@"name"];

NSLog(@"elist=%@",elist);

    NSLog(@"elist=%@",uu);

NSLog(@"elist=%@",u_name);

for (int i=0;i<[elist

count];i++) {

        NSLog(@"遍历数组 \n %i=%@",i,[[elist

objectAtIndex:i] objectForKey:@"name"]);

    }
