JSON響應和NSDictionary的

Question

我在iOS開發新的，我打電話返回我的數據，如

[ 
    { 
     "ID": "3416a75f4cea9109507cacd8e2f2aefc3416a75f4cea9109507cacd8e2f2aefc", 
     "Name": "2M Enerji" 
    }, 
    { 
     "ID": "072b030ba126b2f4b2374f342be9ed44072b030ba126b2f4b2374f342be9ed44", 
     "Name": "Çedaş" 
    }, 
    { 
     "ID": "093f65e080a295f8076b1c5722a46aa2093f65e080a295f8076b1c5722a46aa2", 
     "Name": "Çelikler" 
    }, 
    { 
     "ID": "7cbbc409ec990f19c78c75bd1e06f2157cbbc409ec990f19c78c75bd1e06f215", 
     "Name": "Çoruh EDAŞ" 
    }, 
    { 
     "ID": "70efdf2ec9b086079795c442636b55fb70efdf2ec9b086079795c442636b55fb", 
     "Name": "İçdaş" 
    } 
] 

現在我試圖讓它陣列中的Web服務，該陣列將是獨立的名稱和ID，我做了，直到採取在NSDICT下面是我的代碼

-(void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
    NSLog(@"finish loading"); 
    NSString *loginStatus = [[NSString alloc] initWithBytes:[webData mutableBytes] 
                length:[webData length] 
                encoding:NSUTF8StringEncoding]; 

    NSString *responsewith = [[NSString alloc] initWithData:webData 
                encoding:NSUTF8StringEncoding]; 
    //providerData = [NSKeyedUnarchiver unarchiveObjectWithData:webData]; 
    providerDropData = [NSString stringWithFormat:responsewith]; 
    NSLog(@"drop %@",providerDropData); 

    NSArray *providerData = [providerDropData valueForKey:@"ID"]; 
    NSLog(@"jey %@",responsewith); 
    NSLog(@"resonser %@",responsewith); 
    NSLog(@"laoding data %@",loginStatus); 
    //greeting.text = loginStatus; 
    [loginStatus release]; 
    [connection release]; 
    [webData release]; 
} 

，當我試圖保存NSDictionary到NSArray爲@"ID"應用得到墜毀。

請幫

Answer 1

您可以從JSON像下面的方式以及獲取數據，

id jsonObjectData = [NSJSONSerialization JSONObjectWithData:webData error:&error]; 
    if(jsonObjectData){ 
    NSMutableArray *idArray = [jsonObjectData mutableArrayValueForKeyPath:@"ID"]; 
    NSMutableArray *nameArray = [jsonObjectData mutableArrayValueForKeyPath:@"Name"]; 
} 

Answer 2

將數據轉換爲NSDictionary通過解析，那麼你可以使用KVP提取。

NSDictionary *responseDict = [NSJSONSerialization JSONObjectWithData:response options:0 error:&error]; 

Answer 3

你只是想用NSJSONSerialization

NSError *error = nil; 
NSArray *results = [NSJSONSerialization JSONObjectWithData:webData options:0 error:&error]; 
if (!results) 
    NSLog(@"%s: JSONObjectWithData error: %@", __FUNCTION__, error); 

// get the first provider id 

NSString *providerData = results[0][@"ID"]; 

Answer 4

NSDictionary * providerDropData = [NSJSONSerialization JSONObjectWithData:webData error:&error]; 
NSLog(@"drop %@",providerDropData); 

NSMutableArray *providerData = [NSMutableArray new]; 
NSString *key = @"ID"; 
for (key in providerDropData){ 
    NSLog(@"Key: %@, Value %@", key, [providerDropData objectForKey: key]); 
    [providerData addObject:[providerDropData objectForKey:key]]; 
} 

NSLog("ID Array = %@", providerData]); 
}
