從Web服務接收到JSON響應之後。我有從Web服務iOS 7：以級聯方式使用NSDictionary反序列化後獲取JSON響應
{"d":"{\"Status\":0,\"Message\":\"Registered Successfully\",\"Token\":\"281fecff-2d44-4530-bc24-03558f1ebda1\",\"CurrentTimestamp\":\"23-09-2014 09:58:39 +05:30\",\"ValidUntilTimespan\":\"23-09-2014 09:58:39 +05:30\"}"}
這種答覆，我已經刪除「d：」首先這反序列化字符串和「\」，使其有效的JSON解析 。
NSString *responseData = [[NSString alloc]initWithData:receivedData encoding:NSUTF8StringEncoding];
responseData = [responseData stringByReplacingOccurrencesOfString:@" " withString:@""];
responseData = [responseData stringByReplacingOccurrencesOfString:@"\\" withString:@""];
responseData = [responseData stringByReplacingOccurrencesOfString:@"\"d\":" withString:@""];
responseData = [responseData substringToIndex:[responseData length] - 2];
responseData = [responseData substringWithRange:NSMakeRange(2, [responseData length]-2)];
NSLog(@"Reponse data %@",responseData);
NSData *jsonData = [responseData dataUsingEncoding:NSUTF8StringEncoding];
NSError *errorJson=nil;
NSDictionary *myDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&errorJson];
NSLog(@"Final %@",myDictionary);
NSString *valueMessage = [myDictionary objectForKey:KeyMessage];
NSString *valueStatus = [myDictionary objectForKey:KeyStatus];
NSString *valueCurrentTimestamp = [myDictionary objectForKey:KeyCurrentTimestamp];
NSString *valueToken = [myDictionary objectForKey:KeyToken];
NSString *valueValidUntillTimepstamp = [myDictionary objectForKey:KeyValidUntillTimepstamp];
//values
NSLog(@"Message = %@",valueMessage);
NSLog(@"Status = %@",valueStatus);
NSLog(@"currenttimestamp= %@",valueCurrentTimestamp);
NSLog(@"token= %@",valueToken);
NSLog(@"validuntiltimespan= %@",valueValidUntillTimepstamp);
這是我的日誌結果：
014-09-23 10:03:13.885 Sbits_Journal[1015:60b] Response data {"Status":0,"Message":"RegisteredSuccessfully","Token":"281fecff-2d44-4530-bc24-0 3558f1ebda1","CurrentTimestamp":"23-09-201409:58:39+05:30","ValidUntilTimespan":"23-09- 201409:58:39+05:30"}
2014-09-23 10:03:13.886 Sbits_Journal[1015:60b] Final {
CurrentTimestamp = "23-09-201409:58:39+05:30";
Message = RegisteredSuccessfully;
Status = 0;
Token = "281fecff-2d44-4530-bc24-03558f1ebda1";
ValidUntilTimespan = "23-09-201409:58:39+05:30";
}
但我正在逐漸在串聯方式「RegisteredSuccessfully」字符串響應喜歡這個 但我想只取這個字符串，並顯示警報由於越來越串狀我無法在警報中顯示「已成功註冊」。 這是正確的方式我已解析或有沒有任何其他的方法來凍結？ 提前致謝。
