我的JSON的网址是http://api.kivaws.org/v1/loans/search.json?status=fundraisingJSON的Objective-C - 对象和数组结合

我Objective-代码显示PAGE_SIZE：20使用下面的代码

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"]);

我的问题是我如何循环以Loans数组显示以下内容示例它将显示名称，显示所有语言，状态以便输出看起来像
====================== === ===
名称： “玛丽亚路易莎”
语言：ES，EN
状态： “筹款”
部门： “零售”
位置

COUNTRY_CODE： “NI”

名称：“Florence” 语言：en
状态：“筹款”
部门：“零售”
位置
COUNTRY_CODE： “KE”

井loans阵列处于顶层JSON对象，所以：

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. 
}

由于它的伟大工程，唯一的问题是我没有得到国家，对。当我使用，NSDictionary *位置=贷款[@“位置”];它给了我国家和country_code。我只想要“国家”。与geo同样的问题（我只想要配对） – user580950

@ user580950对于另一个集合中的每个集合（即字典/数组内的字典/数组），您需要使用类似的模式。我会更新我的答案，展示如何让国家走出去。 – trojanfoe

非常感谢:) – user580950

以及你的loans对象是一个字典数组。

通过[JsonObject objectForKey:@"loans"]你正在获得一个数组。

那么你需要迭代期望的结果。

NSArray * arrloans = [JsonObject objectForKey：@“loans”];

for (NSDictionary *dicloans in arrloans) { 
    NSString *name = [JsonObject objectForKey:@"name"]; 
    NSString *countryCode = [[JsonObject objectForKey:@"location"]objectForKey:@"country_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]; 




// Get loans array from JsonObject 
NSArray *loanJsonObject = JsonObject[@"loans"]; 

// Create a new loans array for store the new items 
NSMutableArray *newLoans = [NSMutableArray array]; 

// Loop loanJsonObject to get items and create new ones 
// for then store them in the new loans array 
for (NSDictionary *loan in loanJsonObject) { 
    NSDictionary *newLoan = @{ 
          @"name": loan[@"name"],

           } 
          } 
          }; 

    [newLoans addObject:newLoan]; 
} 

// the new loans 
NSLog(@"newLoans: %@", newLoans);

我检查它，它显示所有记录我如何nslog一次记录一次？我试过以下但它不工作 NSArray * loans = JsonObject [@“newLoans”]; （NSDictionary *贷款贷款）{ NSNumber * languages = loan [@“languages”]; NSString * name = loan [@“name”]; NSDictionary * pairs = loan [@“pairs”]; NSDictionary * sector = loan [@“sector”]; NSString * country = loan [@“country”]; NSString * status = loan [@“status”]; //等 NSLog（@“languages =％@”，languages）; } – user580950

JSON的Objective-C - 对象和数组结合

COUNTRY_CODE： “NI”
