Ios 解析JSON可以阅读各种字典
我是json新手,遇到了一些困难,我正在尝试解析以下json 但是我不能阅读各种各样的字典Ios 解析JSON可以阅读各种字典,ios,objective-c,json,afnetworking-2,Ios,Objective C,Json,Afnetworking 2,我是json新手,遇到了一些困难,我正在尝试解析以下json 但是我不能阅读各种各样的字典 [{"project": { "id": 123, "name": "Produce RestKit Sample Code", "description": "We need more sample code!", "user": { "id": 1, "name": "Blake Watters", "email": "blake@twotoasters.com" }, "ta

我正在使用AFNETWorking,以下是我的代码:
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
for (NSDictionary *json in [responseObject objectForKey:@"project"]){
simProjects *proj = [[simProjects alloc] init];
proj.description = [json objectForKey: @"description"];
如前所述,您确实有一系列字典。你想要:
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSArray *projects = responseObject;
for (NSDictionary *data in projects) {
NSDictionary *project = data[@"project"];
simProjects *proj = [[simProjects alloc] init];
proj.description = project[@"description"];
}
}
您收到的JSON绝对是一个数组。它是一个NSDictionary数组,每个NSDictionary都有一个密钥项目。
