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=[NSURLURLWithString:@"http://192.168.253.101:8080/ERP/mobile/login.action"];

NSMutableURLRequest *request =[[NSMutableURLRequestalloc]initWithURL:urlcachePolicy:NSURLRequestUseProtocolCachePolicytimeoutInterval:10];

//设置请求方式

[requestsetHTTPMethod:@"POST"];

//设置参数

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

NSData *data=[strdataUsingEncoding:NSUTF8StringEncoding];

[requestsetHTTPBody:data];

//连接服务器

NSData *received=[NSURLConnectionsendSynchronousRequest:request returningResponse:nilerror:nil];

NSString *strl=[[NSStringalloc]initWithData:receivedencoding: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=[temstrdataUsingEncoding:NSUTF8StringEncoding];

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

NSDictionary *json=[temstrobjectFromJSONStringWithParseOptions: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<[elistcount];i++) {

NSLog(@"遍历数组 \n %i=%@",i,[[elistobjectAtIndex:i] objectForKey:@"name"]);

}
