JSON Objective-c - 对象和数组组合(JSON Objective-c - Objects and Arrays Combination)

我的JSON网址是 http://api.kivaws.org/v1/loans/search.json?status=fundraising

我的目标代码使用以下代码显示page_size：20

NSData *allCourseData=[[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://api.kivaws.org/v1/loans/search.json?status=fundraising"]]; NSError *error; NSMutableDictionary *JsonObject = [NSJSONSerialization JSONObjectWithData:allCourseData options:NSJSONReadingMutableContainers error:&error]; //NSLog(@"json object is: - %@", JsonObject); //Print Page size NSLog(@"Page size is %@", [[JsonObject objectForKey:@"paging"] objectForKey:@"page_size"]);

我的问题是如何循环到Loans数组以显示以下示例它将显示名称，显示所有语言，状态因此输出将看起来像 ============================ 姓名：“Maria Luisa” 语言：es，en 状态：“筹款” 部门：“零售” 位置

country_code：“NI”

名称：“佛罗伦萨”语言：en 状态：“筹款” 部门：“零售” 位置 country_code：“KE”

My JSON url is http://api.kivaws.org/v1/loans/search.json?status=fundraising

My Objective- code displays page_size : 20 using the following code

NSData *allCourseData=[[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://api.kivaws.org/v1/loans/search.json?status=fundraising"]]; NSError *error; NSMutableDictionary *JsonObject = [NSJSONSerialization JSONObjectWithData:allCourseData options:NSJSONReadingMutableContainers error:&error]; //NSLog(@"json object is: - %@", JsonObject); //Print Page size NSLog(@"Page size is %@", [[JsonObject objectForKey:@"paging"] objectForKey:@"page_size"]);

最满意答案

loans数组是在顶级JSON对象中，因此：

NSArray *loans = jsonObject[@"loans"]; for (NSDictionary *loan in loans) { NSNumber *ident = loan[@"id"]; NSString *name = loan[@"name"]; NSDictionary *description = loan[@"description"]; NSDictionary *location = loan[@"location"]; NSString *country = location[@"country"]; // etc. }

Well the loans array is in the top-level JSON object, so:

NSArray *loans = jsonObject[@"loans"]; for (NSDictionary *loan in loans) { NSNumber *ident = loan[@"id"]; NSString *name = loan[@"name"]; NSDictionary *description = loan[@"description"]; NSDictionary *location = loan[@"location"]; NSString *country = location[@"country"]; // etc. }
