有時網路獲取的JSON返回的是一個數組，這個時候我們可以將其轉化為字串，然後人為構造成一個字典然後再解析。

    NSURLRequest *request12 = [[NSURLRequest alloc]initWithURL:[NSURL URLWithString:adminURL] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10];
    
    NSData *received = [NSURLConnection sendSynchronousRequest:request12 returningResponse:nil error:nil];
    
    
    
    NSString *str = [[NSString alloc]initWithData:received encoding:NSUTF8StringEncoding];
    
    
    ////////////////將其構造成一個字典再解析
    NSString *str1=[@"{\"result\":" stringByAppendingString:str];
    NSString *STRR=[str1 stringByAppendingString:@"}"];

    NSDictionary* dic12 = [NSJSONSerialization JSONObjectWithData:xmlData options:0 error:nil];
    NSArray *DETAIL=[dic12 objectForKey:@"result"];
    NSMutableArray *TITLEarray=[[NSMutableArray alloc]init];
    NSMutableArray *Title=[[NSMutableArray alloc]init];
