###UICollectionView重排

###级联菜单
![Mou icon](https://github.com/qingyunhe/HQYModules/blob/master/级联菜单.gif)

####实现思路:

1 分别使用两个继承于`UITableViewController`的控制器管理左右两侧菜单,分别命名为`HQYMainCategoryController`(左菜单控制器)和`HQYSubCategoryController`(右菜单控制器).

2 使用导航控制器`push`出来的控制器(命名为`HQYCascadingMenuController`)来管理`HQYMainCategoryController`和`HQYSubCategoryController`,将`HQYMainCategoryController`和`HQYSubCategoryController`添加为`HQYCascadingMenuController`的子控制器,并将子控制器的`view`作为子控件添加到`HQYCascadingMenuController`的`view`中.

3 使用代理传值,将`HQYMainCategoryController`中的数据传递给`HQYSubCategoryController`.

####注意事项:
1 默认`HQYMainCategoryController`的`view`第0行`cell`应该处于选中状态,该业务逻辑应该在`viewWillAppear`方法中实现,而非在`viewDidLoad`方法中实现.

```objc
- (void)viewWillAppear:(BOOL)animated{
    
    [self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:(UITableViewScrollPositionTop)];
    // 显示第0行数据
    [self showSubCategoriesDataOfArrowZero];
}

```

2 默认`HQYSubCategoryController`的`view`展示`HQYMainCategoryController`的`view`第0行`cell`对应的数据.

```objc
- (void)showSubCategoriesDataOfArrowZero{

if ([self.delegate respondsToSelector:@selector(categoryViewController:didSelectSubCategories:)]) {
        NSDictionary *dict = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"health.plist" ofType:nil]][0];
        HYQHealthItem *item = [HYQHealthItem categoryWithDict:dict];
        [self.delegate categoryViewController:self didSelectSubCategories:item.subcategories];
    }
}

```

### <a id="HQYStatusBar自定义状态栏"></a> HQYStatusBar自定义状态栏

![Mou icon](https://github.com/qingyunhe/HQYModules/blob/master/statusBar.gif)

####实现过程:
 1 拿到`UIStatusBarForegroundView`对象
 
 ```objc
 
    UIApplication *app = [UIApplication sharedApplication];
    UIView *statusBar = [app valueForKeyPath:@"statusBar"];
    statusBar.frame = (CGRect){0, 100, 350, 50};
    statusBar.center = self.view.center;
    statusBar.backgroundColor = [UIColor orangeColor];
    UIView *barForegroundView =  statusBar.subviews[1];

```
 2 对系统状态栏的私有属性进行个性化设置(以网络服务商为例)

```objc
 
    UIView *seviceView =  barForegroundView.subviews[0];
    CGRect seviceFrame = seviceView.frame;
    seviceFrame.size.width = 2 *  seviceFrame.size.width;
    seviceView.frame = seviceFrame;
    seviceView.hidden = YES;
    UILabel *seviceLabel = [[UILabel alloc] init];
    seviceLabel.frame = seviceFrame;
    seviceLabel.text = @"66666";
    seviceLabel.font = [UIFont systemFontOfSize:10];
    [barForegroundView addSubview:seviceLabel];
    
 ```
### <a id="HQYDownMenu自定义下拉菜单"></a> HQYDownMenu自定义下拉菜单
####注意事项:
1 不能将downMenuView添加到主窗口中

```objc
  [[UIApplication sharedApplication].keyWindow addSubview:downMenuView];
  ```
  
  而应该添加到HQYDownMenu中
