使用野狗(Wilddog)云setValue写入数据

- (void)viewDidLoad {
    [super viewDidLoad];
    //创建野狗实例化对象 用于随时监听数值变化
    Wilddog *myRootRef = [[Wilddog alloc] initWithUrl:@"https://exile.wilddogio.com/weather"];
    //监听键值
    [myRootRef observeEventType:WEventTypeValue withBlock:^(WDataSnapshot *snapshot) {
        NSLog(@"%@ -> %@", snapshot.key, snapshot.value);
    }];
    //为weather键赋初始值
    [myRootRef setValue:@"Sunny"];

    UIButton* btn1=[[UIButton alloc]initWithFrame:CGRectMake(20, 20, 100, 30)];
    btn1.backgroundColor=[UIColor orangeColor];
    [btn1 addTarget:self action:@selector(changeValue1) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn1];

    UIButton* btn2=[[UIButton alloc]initWithFrame:CGRectMake(20, 70, 100, 30)];
    btn2.backgroundColor=[UIColor orangeColor];
    [btn2 addTarget:self action:@selector(changeValue2) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn2];
}

-(void)changeValue1
{
    Wilddog *myRootRef = [[Wilddog alloc] initWithUrl:@"https://exile.wilddogio.com/weather"];
    [myRootRef setValue:@"Snow"];
}

-(void)changeValue2
{
    Wilddog *myRootRef = [[Wilddog alloc] initWithUrl:@"https://exile.wilddogio.com/weather"];
    [myRootRef setValue:@"Wind"];
