CoreBtn 核心按钮，让界面更专业！如果你不知道是做什么用的，那就继续使用HUD吧。

    以下是一些使用示例：
    //代码
    CoreStatusBtn *btn=[[CoreStatusBtn alloc] initWithFrame:CGRectMake(50, 110, 160, 40)];
    btn.msg=@"登陆中";
    //    btn.shutOffZoomAnim = YES;
    //设置文字
    [btn setTitle:@"我是按钮" forState:UIControlStateNormal];

    btn.backgroundColorForNormal=[UIColor brownColor];
    btn.backgroundColorForHighlighted=[UIColor redColor];
    btn.backgroundColorForSelected=[UIColor yellowColor];
    self.btn=btn;
    
    //添加事件
    [btn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
   
    [self.view addSubview:btn];
    

    //nib
    self.myBtn.backgroundColorForNormal=rgb(121, 36, 98);
    self.myBtn.shutOffColorLoadingAnim = YES;
    self.myBtn.shutOffZoomAnim = YES;
    self.countBtn.backgroundColorForNormal=rgb(167, 132, 27);
    self.countBtn.countNum=60;
    
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(16.0f * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        
        self.countBtn.status=CoreCountBtnStatusNormal;
    });
    
    
    CoreBtn *btn2 = [[CoreBtn alloc] initWithFrame:CGRectMake(0, 0, 100, 40)];
    btn2.backgroundColorForNormal = [UIColor redColor];
    [self.view addSubview:btn2];
    [btn2 Click:UIControlEventTouchDown ClickBlock:^{
        NSLog(@"点击");
    }];
