    // Do any additional setup after loading the view, typically from a nib.
    
    
    NSString * datapath = [[NSBundle mainBundle] pathForResource:@"failureReason" ofType:@"json"];
    NSData * jsonData = [NSData dataWithContentsOfFile:datapath];
    NSMutableDictionary *arrayDic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:nil];
    NSLog(@"----arrayDic---%@",arrayDic);
