对MJRefesh二次封装

因为名字被占用了，改为CMARefresh

    pod 'CMARefresh'

• 添加属性

@property (nonatomic, strong) CMARefreshAdapter *refreshAdapter;

• 初始化

    - (CMARefreshAdapter *)refreshAdapter {
  
        if (!_refreshAdapter) {
  
            _refreshAdapter = [CMARefreshAdapter adapterWithScrollView:self.tableview refreshType:CMARefreshTypeAll];
  
            _refreshAdapter.adapterDelegate = self;
  
            _refreshAdapter.adapterDatasouce = self;
  
        }
  
        return _refreshAdapter;
  
        }
  

• 添加代理

<CMARefreshAdapterDelegate,CMARefreshAdapterDatasouce>

• 选择代理方法

    #pragma mark - CMARefreshAdapterDelegate
  
    - (BOOL)refreshAdapter:(CMARefreshAdapter *)adapter footerShouldEndRefreshingWithNoMoreData:(MJRefreshFooter *)footer {
    return YES;
    }
  
    /**头视图开始刷新时*/
    - (void)refreshAdapter:(CMARefreshAdapter *)adapter didStartRefreshHeader:(MJRefreshHeader *)header {
    }
  
    /**当头部在刷新时开始上拉加载，会停止下拉刷新动画，以下方法同用法*/
    - (void)refreshAdapter:(CMARefreshAdapter *)adapter willCancelRefreshHeader:(MJRefreshHeader *)header{
    }
  
    - (void)refreshAdapter:(CMARefreshAdapter *)adapter didCancelRefreshHeader:(MJRefreshHeader *)header {
    }
  
    - (void)refreshAdapter:(CMARefreshAdapter *)adapter didStartRefreshFooter:(MJRefreshFooter *)footer {
    }
  
    - (void)refreshAdapter:(CMARefreshAdapter *)adapter willChancelRefreshFooter:(MJRefreshFooter *)foote{
    }
  
    - (void)refreshAdapter:(CMARefreshAdapter *)adapter didChancelRefreshFooter:(MJRefreshFooter *)footer {
    }
  
    #pragma mark - CMARefreshAdapterDatasouce
  
    /**定制头视图*/
    - (Class)refreshHeaderOfClass
    {
        return [MJRefreshHeader class];
    }
  
    /**定制尾视图*/
    - (Class)refreshFooterOfClass
    {
        return [MJRefreshFooter class];
    }
