示例代码：

NSDictionary *content = [[[[yourJSONResponseDict objectForKey:@"data"] objectForKey:@"items"] objectAtIndex:0] objectForKey:@"content"];
NSLog(@"Content :: %@",content);

解释 ：

//1. This will give you the "Value" for key "data".
NSDictionary *data = [yourJSONResponseDict objectForKey:@"data"]; 
//2. This will give you the "Value" for key "items" which is inside "data" Dictionary.
NSArray *items = [data objectForKey:@"items"];
//3. This will give you the First Object of "items" Array which is a Dictionary.
NSDictionary *itemObject = [items objectAtIndex:0]; 
//4. This will give you your Final Component named "Content" which is a Dictionary also.
NSArray *content = [itemObject objectForKey:@"content"];
