如何解析此响应并保存到iphone中的数组中

Question

我是objective-c的新手，我已经完成了NSXML解析，但是如何解析这个响应。答复是：

Array
(
    [success] => 1
    [artworks] => Array
        (
            [0] => Array
                (
                    [id] => 105

您发布的响应看起来像是数组的print_r。

正如Terente在他的评论中所说，解决这个问题的最简单方法是让服务器用JSON编码这个数组。

这非常简单，所有客户端都需要做服务器端更换

print_r($array);

与

json_encode($array);

然后，您将能够使用iOS 5 JSON框架或任何外部JSON框架（YAJLiOS，JSONKit，SBJSON等...）来轻松解析响应。

修改

您在问题评论http://staging.paddle8.com/api_v1/artworks/get_gallery_artworks?gallery_id=19中发布的链接确实会返回JSON。

要解析此问题，您需要使用JSON框架。如果你的应用程序需要与5.0以下的iOS版本兼容，我建议你使用JSONKit框架，它已被证明是最快的JSON解析器。

您可以在此处获取：https://github.com/johnezang/JSONKit

将此框架导入项目后，您可以像这样解析JSON响应：

NSString *jsonString = yourResponseString; // yourResponseString is the NSString object you get in response to your call to the API

NSDictionary *dict = [jsonString objectFromJSONString]; // This will return either an NSDictionary or NSArray depending on the structure of the jsonString, in your case, this will be a NSDictionary

// Now to get the array of "properties"
NSArray *propertiesArray = [dict objectForKey:@"properties"];

// Now you have an NSArray will all the "properties" objects in the JSON, you can cycle through this array to create all your objects accordingly

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

    // get the dictionary for each properties object
    NSDictionary *propertyDict = [propertiesArray objectAtIndex:i];

    // now you can access all the variables in the properties object

    // id
    int id = [[propertyDict objectForKey:@"id"] intValue];

    // title
    NSString *title = [propertyDict objectForKey:@"title"];

    // etc ...

}

希望这有帮助

正如@Mutix和@Terente一样，Ionut Alexandru指出，它是一个JSON输出。试试这个链接，它展示了如何在IOS中进行JSON解析。
