IOS开发专题－－－转化解析JSON格式为字符格式（原生类库解析）

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];

[request
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
dataUsingEncoding:NSUTF8StringEncoding];

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"]);
}
