Ios 如何解析JSON响应

这是我的json响应：

我的代码：

NSURLRequest * urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:response url]];
NSError * error = nil;
NSURLResponse * response = nil;
NSData * jsonSource = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];
NSLog(@" %@",jsonSource);
id jsonObjects = [NSJSONSerialization JSONObjectWithData: jsonSource options:NSJSONReadingMutableContainers error:nil];

if ([jsonObjects objectForKey:@"wk_time"] != [NSNull null]) {
    NSArray *itemArray = [jsonObjects objectForKey:@"wk_time"];
    NSLog(@" %@",itemArray);
}

到目前为止，我已经做了很多。我希望获得项目名称、活动名称。如何获取此信息？

NSDictionary*jsonDict=[NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&err]；
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];

NSDictionary *dictUser = [[jsonDict objectForKey:@"wk_time"]objectForKey:@"user"];

NSArray *array = [[jsonDict objectForKey:@"wk_time"]objectAtIndex:0];

for(int i=0;i<[array count];i++)
{

    NSDictionary *dictTimeEntries = [[array objectAtIndex:i]objectForKey:@"time_entries"];

    NSDictionary *dictProject = [dictTimeEntries objectForKey:@"project"];

    NSString *stringProjectName = [NSString stringWithFormat:@"%@",[dictProject valueForKey@"name"]];

    NSLog(@"The stringProjectName is - %@",stringProjectName);

    NSString *stingProjectID = [NSString stringWithFormat:@"%@",[dictProject valueForKey@"id"]];

    NSLog(@"The stringProjectID is - %@",stingProjectID);


    NSDictionary *dictActivity = [dictTimeEntries objectForKey:@"activity"];

    NSString *stringActivityName = [NSString stringWithFormat:@"%@",[dictActivity valueForKey@"name"]];

    NSLog(@"The stringActivityName is - %@",stringActivityName);

    NSString *stingActivityID = [NSString stringWithFormat:@"%@",[dictActivity valueForKey@"id"]];

    NSLog(@"The stingActivityID is - %@",stingActivityID);

}

NSDictionary*dictUser=[[jsonDict objectForKey:@“工作时间”]objectForKey:@“用户”]；
NSArray*数组=[[jsonDict objectForKey:@“工作时间”]objectAtIndex:0]；
对于（int i=0；i，我强烈建议您将JSON结果转换为object。这是一个非常有用且易于启动的库-

通过这种方式，您可以创建一个表示响应的类，并轻松访问所有属性，如普通属性，即
user.name
[[DictJsonName objectForKey:@“wk_time”]objectForKey:@“time_entries”]objectAtIndex:changeNumber]objectForKey:@“project”]objectForKey:@“name”][[[[[DictJsonName objectForKey:@“工作时间”]objectForKey:@“时间项”]objectAtIndex:changeNumber]objectForKey:@“活动”]objectForKey:@“名称”]catherine告诉我你使用该url获得回复的url。请告诉我，如果你给我显示获取回复的url，我现在会帮助你。@user3182143是的，谢谢你的回复，url在我的本地运行…你怎么能使用该url？有什么想法吗…@RamVinayYadav tahnks bro.它工作正常…是的，谢谢兄弟…你能给我你的邮件id吗。…我将发送我的示例项目我有一些疑问…你能澄清我吗…你想要我的个人身份证吗？你为什么取消勾选我的答案？你能给我你的身份证吗？兄弟？告诉我你的邮件身份证。我会发短信给你。
