An easy solution to page controllers like NetEase News

Click here: https://github.com/wangmchn/WMPageController-Swift

• Now page controller has a cache policy and scroll much more fluently!
• Add itemMargin and itemsMargins to custom margin between each item, viewFrame to custom controller.view's frame.
• Add values and keys properties which can help pass values to childControllers through KVC.
• If items width didn't fill the screen width, WMPageController will calculate width and add gap between each item automatically;
• Adjust views and frames when device's orientation changed;
• Set the property itemsWidths to have Different Width! Like @[@(100),@(80),@(50).....];
• Can reload data like NetEase News.

First Drag files in red frame to your project.

Then,create an controller that extends from WMPageController.I recommend to use

- (instancetype)initWithViewControllerClasses:(NSArray *)classes 
                               andTheirTitles:(NSArray *)titles;

to init the controller.Here are two important porperties

classes :contains the classes of view controller, you can put obj in like [UITableViewController class];
titles  :Each View controller's title to show in the menu view at the top of the view;

To have a custom page controller,please set the properties in WMPageController ,They are: titleSize, titleColor, menuHeight, pageAnimatable, menuBGColor, menuItemWidth,rememberLocation,and also itemsWidths.

Override -init method in childViewController, For example:

- (instancetype)init {
    return [self initWithNibName:@"xxxViewController" bundle:nil];
}

pod 'WMPageController'

You can put every controller in WMPageController,But if you want have a UICollectionViewController in, please have an attention to UICollectionViewController's init method.
You should override the - init to give UICollectionViewController a UICollectionViewLayout. Here is an example:

- (instancetype)init {
    // init layout here...
    self = [self initWithCollectionViewLayout:layout];
    if (self) {
        // insert code here...
    }
    return self;
}

WMPageController是一个方便形成如同网易新闻首页，控制器滑动翻页效果的控制器。(原谅我拙略的英文)

戳这里: https://github.com/wangmchn/WMPageController-Swift

• 增加了缓存机制，对加载过的控制器进行缓存，当内存过高时自动清理缓存。
• 可通过itemMargin和itemsMargins来定制顶部标题的间距，通过viewFrame来定制子控制器的frame属性。
• 通过设置values和keys向子控制器传值。(内部利用KVC实现)
• 当标题宽度之和不足宽度时，自动计算并为顶部item添加间隙。
• 适配横屏，当设备旋转时自动调整frame。
• 可通过设置itemsWidths属性来设置不同的标题宽度，例如 @[@(100),@(80),@(50).....];
• 增加了reload功能，可以像网易新闻那样重新更新标题和控制器。

首先，把下面红框里的内容拖入项目。

然后，创建一个控制器继承自WMPageController，并使用以下方法初始化该控制器

- (instancetype)initWithViewControllerClasses:(NSArray *)classes 
                               andTheirTitles:(NSArray *)titles;

其中，Classes是要传人显示的控制器的类型，比如[UITableViewController class], titles是要显示的控制对应的标题。 如要定制WMPageController的外观，可通过设置如下属性： titleSize, titleColor, menuHeight, pageAnimatable, menuBGColor, menuItemWidth,rememberLocation,以及 itemsWidths.

重写子控制器的 -init 方法，例如：

- (instancetype)init {
    return [self initWithNibName:@"xxxViewController" bundle:nil];
}

pod 'WMPageController'

如果需要传入 UICollectionViewController, 需要重写 - init 方法，来为UICollectionViewController提供一个 UICollectionViewLayout。 方式如下：

- (instancetype)init {
    // init layout here...
    self = [self initWithCollectionViewLayout:layout];
    if (self) {
        // insert code here...
    }
    return self;
}
