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 数组以显示以下内容例如，它将显示名称、显示所有语言、状态，因此输出看起来像
============================
名称:“玛丽亚·路易莎”
语言:es,en
状态:“筹款”
部门:“零售”
位置
名称:“佛罗伦萨”语言:en
状态:“筹款”
部门:“零售”
地点
国家代码:“KE”

最佳答案
loans 数组位于顶级 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.
}
