我的JSON的網址是http://api.kivaws.org/v1/loans/search.json?status=fundraisingJSON的Objective-C - 對象和數組結合

我Objective-代碼顯示PAGE_SIZE：20使用下面的代碼

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"]);

我的問題是我如何循環以Loans數組顯示以下內容示例它將顯示名稱，顯示所有語言，狀態以便輸出看起來像

井loans陣列處於頂層JSON對象，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. 
}

由於它的偉大工程，唯一的問題是我沒有得到國家，對。當我使用，NSDictionary *位置=貸款[@「位置」];它給了我國家和country_code。我只想要「國家」。與geo同樣的問題（我只想要配對） – user580950

@ user580950對於另一個集合中的每個集合（即字典/數組內的字典/數組），您需要使用類似的模式。我會更新我的答案，展示如何讓國家走出去。 – trojanfoe

非常感謝:) – user580950

以及你的loans對象是一個字典數組。

通過[JsonObject objectForKey:@"loans"]你正在獲得一個數組。

那麼你需要迭代期望的結果。

NSArray * arrloans = [JsonObject objectForKey：@「loans」];

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

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

我檢查它，它顯示所有記錄我如何nslog一次記錄一次？我試過以下但它不工作 NSArray * loans = JsonObject [@「newLoans」]; （NSDictionary *貸款貸款）{ 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
