如何在 UIContainerView 中连接 UICollectionViewController [英] How do I hook up UICollectionViewController in UIContainerView

问题描述

我有一个看起来像这样的应用:

I have an app that looks like this:

ViewController 是我在其中放置 3 个容器视图控制器的父 VC.
我将 UIViewController 子类化为所有三个，Top，Mid &BottomContainerViewControllers.

ViewController is the parent VC into which I placed 3 container view controllers.
I subclassed UIViewController for all three, Top, Mid & BottomContainerViewControllers.

这是我的问题.我希望 BottomVC 有一个横向滚动的 UICollectionView.所以我添加了一个 UICollectionView 如你所见(给它一个漂亮的绿色背景).

Here is my question. I want the BottomVC to have a UICollectionView which scrolls sideways. So I added a UICollectionView as you can see (gave it a nice greenish background).

但我的问题是，我该如何连接?

But my question is, how do I hook this up?

这是我的 BottomContainerViewController.h:

This is my BottomContainerViewController.h:

#import <UIKit/UIKit.h>

@interface BottomContainerViewController : UICollectionViewController <UICollectionViewDataSource, UICollectionViewDelegate>

@property (nonatomic, retain) IBOutlet UICollectionView *collectionView;

@end

而.m文件有以下方法:

And the .m file has the following methods:

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath

但是当我运行它时，我得到:

But when I run it I get:

[UICollectionViewController loadView] loaded the "qcP-Hl-Txn-view-aJq-Dc-875" nib but didn't get a UICollectionView.'

UICollectionView 插座已连接.还有什么问题?

The UICollectionView outlet is connected. What else could be the problem?

推荐答案

创建一个uiviewcontroller类来管理底层容器.像往常一样使用该视图控制器进行链接.连接delegate、datasource、实现delegate、data source……等等……

Create a uiviewcontroller class to manage the bottom container. Link as you normally would using that view controller. Connect delegate, datasource, implement the delegate and data source... etc...
